Well, you should have mentioned so in your question, don't you think? :)
Anyways, there is nothing called cannot do. So I'd tell you the solution that comes off the top of my mind.

Normally, the user you use to run your website as is not given 'write' permissions. For obvious and potential security reasons. So security aspect of this, I'd leave it to you, should you choose to implement it.

All you have to do is, create two web pages, or a web service with two method calls for this matter. One method/page should allow, you to get the list of files/directories (say an array of file names and sizes) in a certain location and the other method should allow you to upload a file and save it to the location you pass along.

You haven't mentioned whether this synchronization is one way or two way and how the synchronization is triggered. But regardless, with the usage of these 2 functionality you should be able to compare the list of files/folders and sync where necessary. It may be a scheduled task or it may be done upon a request to another web-service; I'd leave the implementation details for you.

Lastly, for this to work, you should allow the user with whom you are running on localhost, the privileges to write to folders. My last advice is security, security, security, security. Because, if you leave this unprotected in any sort, you won't have much left :)

Hope this helps, regards

Reason for my vote of 5 \n This simple solution is elegant :)

We don't have an idea about the states and triggers about what you are talking :) If you provide a code sample of what you tried and where you fail exactly. We can help you easily :)

Yet another Google search, don't you think? Have you tried?

Hey there,

Firstly, your question is not clear at all. I understand that you might have sensitive data in your tables, by all means remove them. But please, do change them to something we can understand (e.g.: to an example which shows some logical relationship).

Secondly, I believe your problem can ideally be solved at a SQL level (or database level), if I am not mistaken.

If you elaborate more on your problem, am sure someone would be able to answer you faster.

Regards

Just a quick tweak on your Button1_Click code

if (!string.IsNullOrWhiteSpace(TextBox1.Text))
TextBox2.Text = TextBox1.Text.Substring(0, 2);


Hi Bhargava,

Your code is correct. The only thing missing is that, your view doesn't understand what is the exact type of your Model is. By adding the line,
@Model List<Users>
to the beginning of the view file, you tell to the parser that, your model is of the type of a List of Users. Then only the parser knows how to map the properties in your view.

Hope this helps, regards

Hi, I added this part of your question to the question itself. What you need to realize is that, an image is a certain format of bytes, not just some bytes. When you encrypt you destroy this format and it becomes a meaningless set of bytes. Therefore, you cannot display it, unless you decrypt back again

I get what you mean by an encrypted image. Let me get back to you on that :)

Regards

lol :D I feel your frustration. The number of people who don't know to form a question properly is too damn high :\

Prabhat, let's imagine you make customized cages for animals. If i come and ask Hi, 'I am in need a cage to put my pet', what would you say? You'll first be like 'errm.. crazy guy' and ask 'what do you have for a pet? what is the size of it?' and so on. Because, without that it's impossible for you to come up with a cage with correct size. isn't it?

Likewise, we can't either. The other difference is, we are not doing a business here. So give us all the relevant information you got, so that we can help you. A few examples, explanation of the problem you faced, sample code, etc. would be really nice. Otherwise people wouldn't even bother to help you (even though I took this time to type all this hoping you'd learn how to explain a problem of yours to someone else).

How do you expect someone to know that image was encrypted using what method?

Please, improve your question

agreed :)

hehe, I got it but thought others might not, that's why :)

Correct answer :) My 5

Just a small note, you've used '==', it should be '=' :)

He means to 'programmatically' even though there is no such word :) I know you could understand :D Don't pick on the fellow, sin :)

Well, I've been dying to write a code snippet to shut down my router but couldn't. If someone could add that too to his question, it would be awesome :P

:D I'd bet on it that your regular expression is not validating capital letters. If you want some other error to be fixed let me know. Good luck

@Professionals above this comment: Don't pick on the poor fellow :D Point him in the right direction would you? I bet any of you can write few steps for him to get the basic idea :)

Why don't you guys use Google? :S
Server.Transfer vs Response.Redirect[^]

Rather than a concrete implementation, teach the principals/theory behind of a solution, which he/she can reuse << This is something I strongly believe :) And you have done it exactly. My 5

What's stopping you from using the image itself as a button? :) If you are using WPF, this is achievable easily

Indeed, it won't compile since the String class have not got a constructor with a string parameter. But there are other string constructors and is very useful in some cases :)

We'll need to know what videoData is, don't you think? :)

Of course there is :) Go to the link below, search for 'SelectedIndex', 'SelectedValue' and 'SelectedItem'. Play with these properties and you'll figure it out
http://msdn.microsoft.com/en-us/library/e0ybx34e.aspx

Good luck :)

Can't you post a sample code replicating your problem? It's impossible for us to help you out other than taking wild guesses based on our experience :)

@Pratik: No-one will give you a complete solution, if I am not mistaken and you will also not learn anything. Start creating some small web application. You will face lots of problems. Read books, use the knowledge you acquired previously, use google and solve them. You'll get one or more problems that you won't be able to solve how much you try, then come and post here about those problems. These guys would jump to help you out. In short, no one will spoon feed you, this is not a school :)

Nicely put. But if I may add to that, by answering lot of questions that are poorly elaborated, our frustration builds up and some may not see the sarcasm/hint that we try to provide for him to think and understand by himself.
Therefore, I personally take care (I lose it too :D) to put it simple as possible and retain from long arguments/discussions off the topic/problem. :) Just my 2 cents

Sigh. Another one...

How could another person know these by the information you've given?
1. What is 'running condition'?
2. Windows application is shown in the taskbar by default. Do you mean systems tray?
3. Should this be achieved in a windows application, service?
4. What should you be 'running' in this 'running condition'?

I also attempted to achieve this by hooking onto those events. But didn't have any luck. Let's see, others might have found out something different

Allright, another one who don't know to explain his problem. *deep breath*

You want to store the data in your datagrid in a two-dimensional array. Am I correct? Do all the columns in the datagrid have the same data type? If so, what is the data type?

One more thing, you cannot store table-like data in a single dimensional array unless you store objects in the array.

:) Glad I could help

Read your question out aloud to someone close by to you and see whether that person would understand it. And with that attitude, good luck with getting an answer :)

:D lol. I feel your pain SA. People's ability to explain a problem of theirs is vanishing at an alarming rate around here in CP. It takes 2 sets of skills now, to answer a question. One to read and understand the question and the other one is technical/development knowledge. The beauty of it is, we need the first skillset more than ever now :D

You beat me to it :) These were the exact articles I was going to refer to him. My 5

@Kartheek: They are asking what is the 'msg' you get on 'OnError()' method :)

What do you mean 'saving an image'? Is it that you trying to upload a file or something? Or, you generating such a huge image and want to save it?

It is nearly impossible for people to answer you without seeing the table or the class structure of the 'tblAdmins' and 'tblCities', don't you think? Most probably, you would have got an answer by now, if you did :)

Hi there,

Well, you've spotted the problem of that kind of initialization already.

First and foremost thing; It is hardcoded and you will not be able to pass a complex type like that. For instance, to initialize a Student class and set the first name and last name, and assign it to the property.

Secondly, if it's a value that is set in the initialization it's probably a value that do not change over the span of object life cycle. It's best to set these fields as readonly.

Thirdly, you've gone a factory pattern. The whole concept of it is to have dumb clients. As in when you've set the data in the derived class, the structure of the factory pattern is lost. One thing to remember is that all these count when in terms of future updates, scalability and testing.

Don't you think it's impossible to debug a code without the code? I mean, you can guess where the problem might be, but it's like looking for a red color ball in a bag full of balls with your eyes closed.

Fixed it for him :)

*facepalm* Are you like serious? I would love to know how on earth you expected us to figure out how you created the textbox dynamically and what is the name of it and the what is the validation you want and so on. Am sorry, but after seeing so many people posting questions this way over and over again, it's impossible to believe how many people don't have the common sense to tell their problem to another person properly even.

How do you feed the hindi characters to the system? Did you try outputting the raw input and see whether the input and the received input is identical? Perhaps, your methods are working fine :) I'll check up on the methods anyways

WOahhh Kuthuparakkal. Shouldn't you be a bit concerned about your language in such a public forum? I suggest you reflect more professionalism in future. Btw, you don't have to sign into that site, just click the link and fill in the captcha code and the file is downloaded.

Dictionary<string,>> Dic = new Dictionary<string,>>(); <<< ????
How can you even compile this code unless you've made a mistake in copy pasting your code.

He've mentioned that both are always null, isn't it?

Don't use string concatenation for obvious reasons. Use a StringBuilder instead :)

By far the most elegant solution :) string.Join is one method that's overlooked by many. My 5

List<string> names = new List<string>();
foreach (ConnectionStringSettings connectionString in ConfigurationManager.ConnectionStrings)
{
names.Add(connectionString.Name);
}
// This for loop gives you the list of names, bind this to the drop down


string countryConnectionString = ConfigurationManager.ConnectionStrings["selected connection string name"].ToString();
// This gets you the connection string based on the selection

Isn't it easier to give a DateTime picker?

How are we supposed to know what your 'proper format' is? :S Tell us how you want to the data to end up? E.g. In a Dictionary<string, object=""> instance

ERrrmm.. How are suppose to know how you set the image? If you set the width and the height of the image using CSS, it is not going to change regardless of the browser unless you change it or run JavaScript that modifies it

We have your data; it's clear. Give us 3 examples of sample input and expected output, so we can work out the logic that we can't get by reading your question :)

Well, some people are not profound :) I bet he wanted an answer that adds the number of days of a particular month to the combo box. So why not give him such a simple answer but write comments longer than the answer? just a thought, no offense :)

why would you need to define it an array and copy it? I know memory is freely available these days but this is using way too much memory for a simple problem.

1. You've defined an array >> Takes memory
2. New array object is created >> takes memory again
3. Array copy >> a loop is run inside the array to deep copy the contents to your liking
4. AddRange >> Another loop is run to add the items

Your code is highly unoptimized, If I am not wrong.

You should really post a sample code at the very least. Your question might sound very simple and straight forward to you because you know the context. But the people who look to help you have no clue about it :) It helps them understand your problem easily

If you want to demand your needs, go to your parents :)

Hi there,

It would really depend on your browser settings or your code. We can't tell much from the info you have given in the question. But, do play with the values which are valid for the 'target' attribute and see how it goes.
http://www.w3schools.com/TAgs/att_a_target.asp

Not everyone can express their problems in a way that others can understand. It's a skill that some does not possess. But there is a rarer kind of people who can understand the above mentioned type of people. And Clifford, I think you've given him exactly what he wanted, even though he couldn't express it.

Hats off to you for the answer and for not running him down when you could understand. 5 Points from me! Keep up the good work

oh it's a web :) Ok, the first thing I can see is that, you have not accounted for the exception that could occur if, the "FindItemByText(string value)" could not find your value. You should encapsulate it with a try/catch block.

Apart from that, since you are sure that the item HEX NIPPLE 7/8" is there in list of values, I think you might have white space at the beginning or end of your value. Try trimming all these values before you enter it to the list and in that line of code too.

comboBox.SelectedIndex = comboBox.FindItemByText(selectValue.Trim()).Index;

ERrrmmm... Hello??? Does anyone happen to notice that the Image.FromFile method requires the FILE PATH to be passed as the parameter, not the contents. (ref: http://msdn.microsoft.com/en-us/library/e6ytk052)

Secondly, a PICTURE is a BLOB object (i.e. a binary file), not a string file.

Please, correct me if am wrong :) But I seriously think you guys are mistaken.

Sudheer, your solution is the optimal in this kind of scenario, but you have to add a simple if clause for it to be error prone.

if (ColorNames.length > 0)
ColorNames = ColorNames.Substring(0, (ColorNames.Length - 1));

or

if (dt.Rows.Count > 0)
ColorNames = ColorNames.Substring(0, (ColorNames.Length - 1));

would do the trick :)

Hope this helps

Please, specify whether it's a web application or a desktop application. The implementation differs largely based on that.

Am I seeing things or am I seeing two identical 'button1_click' methods in the same scope?

:) I think you need to add quite some details for this question. Take your time, lol.

The easiest thing to do is a write a stored procedure to perform all this logic and call it when required. Then you do not have to bring all the data to the client side but only the processed and required data.

@SA: He might be having his own reasons. Let's not critisize but try and help. :)
@Member 8658209: All you want to show is one child window at a time. Is it?

You should give us more details. For instance, in .Net Framework 4 (Visual Studio 2010) all I have to do is to set "HorizontalScrollBar" to "true".

Well, what is the problem you have? Cannot see a problem to solve. The best way depends on what you define as best. Is it the speed, memory efficiency or simplicity of the code or what? If you say overall, well you have to try and write some code and see. We are here to aid you in a problem, not to write code for you. :) Hope you get it.

XML files are plain text files, it would be easier to be manipulated as a string so that it can be split. Afterwards, you can convert each node to a XML Node and do as you please.

You have to tell us on which conditions should you split the path (i.e. on what criteria you decide the place where you want to split the path). An example without that is pretty useless. In which case, the answer given by 'digimanus' is pretty suitable :)

Should not be the case :) Converting int to an int or converting any type to the same type should not fail in any case. I mean, there is NO logical explanation for that :)

:) Agreed.

Nice answer :)

Nice code. But would have been so much better if you posted this an article and shared the link here :) I bet there are a lot of newbies (like me :D) looking for a simple code like this.

Lolz :) I am laughing at SAKryukov not you.

I don't laugh or make fun of people because, they don't know something. I am not that low. Anyways, my bad, I should have posted this as a reply to SA's comment, instead I just hit d "Add Comment" link.

Thank you :)

@SA: did not even call it exception... I am angry with you << lol!

No offense, you just sounded as if you are a child. Helped me laugh a bit at work :)

I've seen that thread before :) It's not that he can use docking here. He is just wants the form to resize based no the size of the right panel, which is only 1 control (if I am not wrong). I just want to confirm it, if so, it's just simple math :)

Explain your exact scenario please? If it is just that you need to re-size the form when the right panel size changes, it's very easy :)

Try,
Uri = matchUri.Parse<typeof(response.uri)>();

Well, the link worked fine for me by then and it still is :) So I thought you actually haven't tried. Anyways, try once again and post here if you cannot access it, I'll do this as an article and post the link here, so that anyone else also can see.

Please, do not post email addresses here. Update your comment and remove it.

If you read the comments in this thread, I have posted a link to a sample that I have done.

Regards :)

Wow. I have done many applications which involved storing file paths in the database, but a similar problem never occurred to me. May be this is a MySQL issue, I know not.

I'd surely go home, try it out myself, and post here.

On a final note, can you post the code in which you get the file path and pass it on to MySQL (database code part?). If it's a glitch in your code, I'd be able to help you sooner.

Regards

Lolz. Wasn't making fun out of OP but was trying to emphasize that it's his own code that is causing this.

Btw, Thank you for the vote:)

Windows forms do not have any viewstate nor session :)

If you don't want postbacks, your friend is AJAX. Just Google on it, you will get plenty answers.

Glad I could help :) and thank you for the vote

Lolz :) He updated the question. If you look carefully, you'll see I posted this 1 hour earlier than he posted :)

Points I do not care much (rather at all), all I am trying is to help people. Thanks anyways :)

Thank you :)

I don't know whether you skipped some code, but I can't see you showing the form. I think I found the glitch in your code.

You need to decide something :) Are you going to set the mode of the form when the form is shown? or is it that the form is always visible and a button in another form is clicked and it changes?

I did a very small example of what you need to do. Download it and see, I think the link expires in a day or something. So hurry.
http://www.filefactory.com/file/cb192b8/n/Cardon.FormStates.Test.zip

Hope this helps you :) Regards

I hate to say this, but if you Google these 2 things, you will get MORE than you want. I really do not know why, you can't do it. You can't be a developer if you don't do 2 simple things (1. Research 2. Trial and error).

You just copied code from an external link (http://helpdesk.ingeardrivers.com/supportsuite/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=42). You didn't customize it or put a comment or even change it to show an example. Do you at least checked whether this works? *Thumbs down*

Any specific reason that you want to use sbyte instead of byte?

:) Thank you

You mean to read an email in the inbox and save it in the database? Is it? What is the email provider you are hoping to use?

Lolz. Too harsh dun u think? :D Poor fellow

Good answer, but please, don't use string concatenation in SQL. Very bad practice :)

Lolz. Funny as may it sound, or even harsh for that matter, this is the optimal way to answer to these kind of questions.

I mean how hard is it to type "what is a listbox" in google instead of browsing to CodeProject click "ask a question" and posting it here. Oh, I missed logging in also.

Being spoon fed in schools by teachers, these people tend to ask it off from someone rather than finding it themselves, regardless that it is something so simple and basic :S This mindset should be changed *sigh*

If this is hosted in a public domain instead of a machine on the intranet, I strongly suggest do not go for IP filtering, because it is not practical. It would be really hard to maintain.

For me, it does not make sense to host your internal website in a public domain and try to restrict access by IPs. It would be soo simple and effective to host in a server within your network which is not accessible through internet. Then, all you have to worry about is users accessing it from a different PC instead of his/her own pc :)

Please, refer to the community content in the below link. Might help you

http://msdn.microsoft.com/en-us/library/s1ax56ch

I also would like to know the answer to Rajesh's question and to one more question.

You talk about converting, is it to another data type? or is it just that you want to format it so that you could display it? or is it just that your calculation precision is 4 decimal points?

On a side note, double abc = 23.22d; sets abc to 23.22000000 so it won't affect your calculations at all, the only place where it would affect is while displaying. Please, correct me I am wrong and give us an example of such an instance :)

Good answer :) You should add "ViewState" and "Cookies" to this

Look for something called "global keyboard and mouse hooks". These are a set of API which allows you to trigger events when the user moves the mouse or uses the keyboard. There are plenty of articles written about it in CodeProject itself.

Hope this helps :)

lol @ yesotaso

I remember feeling like that in my "threads and concurrency" classes :D

Please, do not suggest code with string concatenation for SQL. It is very bad practice. The OP already is using SQL parameters to pass data and help debug errors in his approach :)

Yes, they should :)

:) U said you drew a rotated rectangle, which means you must have had the co-ordinates of the right-bottom corner when you drew it. Why don't you save it and re-use? Or if this is a custom component that we are talking about, can't store it as a property of the component?

:) Thanks

:) Thanks, but I am not that good plus I didn't find a suitable topic. There are almost everything you want in the net, you just have to search for it.

Thank you :)

Also, you should check whether the return value of ExecuteNonQuery

if (affectedRows == 1)
MessageBox.Show("Successful");
else
MessageBox.Show("Failed");

In case of an error also, the same :)

hehe. Sorry I didn't mean you were harsh.

I just meant that, OP didn't know how to achieve it. OP wanted to go ahead and write the code himself/herself. But wanted to check whether it's already there in .Net Whether it's banker's rounding or not, OP didn't care (Even I didn't know that it was called that before you mentioned :D)

We all are trying to help :D Thumbs up for your effort :)

OP has no idea about Math.Round. (Proof: Now should i have to code it or is there any built in functionality in c#.)

My 5 :) You should not spoon feed neither be harsh. Way 2 go.

It should NOT be happening. :S Weird if it is so. Do you mind posting a sample code? So we can try it out?

Try using this class for constructing connection strings, if you don't know what you are doing. It helps you alot :)

http://msdn.microsoft.com/en-us/library/system.data.common.dbconnectionstringbuilder%28v=VS.80%29.aspx

You want to open a file "aaaaaa.mgf", edit it, write the contents to a text file with the name "aaaaaa.mgf modified.txt"? Is it?

:D

Exactly, If he tried this one out, he would have easily bound the image to the data source and it would work simply like that. Would it kill these people to try abit and post what they have tried? :(

:) I am not here to hand him the solution or give him the code. I don't think any of us are here for that. I pointed him at the right direction. He can work on it and come back with his problems, where we can help him, if we can.

In fact, why I did not tell anything other than to use VBA, is for a reason. Simply because, VBA has built in methods to do these.
1. Open 2 workbooks - Workbook.Open
2. Copy sheets - Sheets.copy

Just an example, might not be the exact signatures :)

@tnd2000: Have you heard of Dining Philosopher's problem? It is a problem used in teaching Threading :) It uses multiple threads.
@Tirmit: To simulate the time taken for eating, thinking, etc. you should not use a timer. There is a thread for each philoshopher, right? Define a global constant, and use a Thread.Sleep(Constant); after each action (eat, think, etc.) When an action finishes, use the notify method to wake the threads up :)

Ok. First of all, replacing your question, with your complaining, DOES NOT help! You should have posted your latest update to the question as a comment to his solution :)

Anyways, after going to the revisions and actually reading your question, I think your parallel port number is hard coded, which should be the main problem. I suggest you move the port number to a App.Config and load it from there. When testing on other computers, try changing the port number and load.

In your code, the port number you've used it 889 where in almost every article that I searched up uses the port number 888 :) I am no good in this area, but just a suggestion.

Hope this helps :)

Do you have a if (!isPostBack) { /* code */ } block that fires in your page load or a similar event? This might be the case.

Also, the easiest way is to determine this is to place a break point in the code where you bind the data to the data grid and see if it fires when you just post back.

:) I believe, there are lots of different people in the world and not everyone is great or even good in what they do or try to do. Some are born intelligent and some are hard working.. Whatever it is, I believe in trying to help everyone I could, for I am grateful that I possess the knowledge and a brain that could help that person out in some way.

I do agree with your point in your solution, but I just don't think, it applies to everyone, since there are very bright or intelligent people who cannot understand a heck of programming, just because they didn't understand the basics in programming. Doesn't matter who is at the fault of it, what matters is what we can do about it or rather that we at least tried. Isn't it?

So I don't scold or be harsh or mock people who are weak, but rather try to break it into a level that they could understand. That's it :)

Thank you for your answers, I update my solution based on your answers :)

Run your application and go to this particular webpage. I hope you know to use a tool like FireBug (http://getfirebug.com/) to check the HTML of the page. You will need Firefox to use this tool though. Although, you can use developer tools in IE 8 :)

Use such a tool to check the names of your gridview. Check whether the radio buttons are rendered with the same name "radiobutton1" or in an incremental way like Wayne suggested. This will help you capture your problem.

:) Oh.. How many records are we talking about here? 100000 at least? And what is the value of the blank cell? A space??

Blank = A space? :)

@SA: I think he meant, the fields in his table does not allow nulls.

@Abhinav: Why don't you try checking the length of the field after trimming? If it is zero, it should be the blank :) Just a thought

The easiest way to find this out is to download a simple tool which displays such data and run it on a guest account :) You'll get the answer.

Thnx :)

Hey there,

I've got 2 suggestions.
1. Change your SQL to something very simple like "SELECT COUNT(*) FROM Employee" and comment the code where the parameter object is created and added. Run the application and see, if it works, that should be the case where "txtnum" does not have a value
2. Check your database connection string. I am not that familiar with OleDBConnections with Access. Something says to me that the problem lies in your connection string.
Try using this class to construct your connection string? (http://msdn.microsoft.com/en-us/library/system.data.oledb.oledbconnectionstringbuilder.aspx)

Hope this helps :)

Hi Sameera,

That line is there for a reason. Look at the line below which taken out from your code.

string fnd_data = "select count(EmployeeN0) from Employee where EmployeeN0=" + "'" + txtnum.Text + "'";

In commercial application development, this is considered very bad practice in developing applications. This is due to a hacking approach named "SQL Injection" (http://en.wikipedia.org/wiki/SQL_injection) which can be used to destroy your database or get access to the restricted data.

There are numerous ways to prevent this, but the way I've done it is the easiest. You can read more on it (http://www.dotnetperls.com/sqlparameter). What happens there is, in SQL you can define parameters in the SQL using the "@" sign.

select count(EmployeeN0) from Employee where EmployeeN0 = @EmployeeNo << notice the "@EmployeeNo" . This is how you define a parameter in SQL. So in this SQL there is only one parameter and it's name is "@EmployeeNo". So what you need to do in the code is to pass data into this parameter.

OleDbParameter employeeNumberParameter = command.CreateParameter(); // Creates a parameter from the command, but does not add to it
employeeNumberParameter.ParameterName = "@EmployeeNo"; // Set the name of the parameter
employeeNumberParameter.Value = txtnum.Text; // Set the value of the parameter. When the SQL is executed, this value will replace the "@EmployeeNo" which is taken care by whatever the database software you use, in your case, by MS Access
command.Parameters.Add(employeeNumberParameter); // You have to add the parameter you created to the command, other wise the code will look for the parameter details and throw an exception saying it is missing.

Hope this helps :) Regards

rofl :D This is fun.. I am bored @ wrk n u r just awsm... Quick tempered ppl r vry easy 2 pick on, u know dat? :D Kk.. I'll stop :D

Btw, no offense meant. Just gave it my thoughts. No hard feelings mate :) Keep up the good work. But it won't kill to be not to be perfectly correct... Just a thought. Bbye

Lol.. Plz dun take things personal :D Come on man, you are acting as if I said you should be extinguished from earth.

I just pointed out that your solution won't work for his question as I think. The "Solution 1" is more appropriate in d sense of generating the ID. If it was joined with your solution (if that was done inside the event you mentioned), it would be a perfect solution. That's it.

Nothing personal. lol. You got issues man :D

Requirements? I have too. :lol: But look at this instance, not other instances. This requirement :)

If the fixed string is not preferred you do not add the preceding 0's. He meaning to use the 3 digit fixed length number along with "A" prefix means, he needs one. Isn't it? Any idea or experience of requirements which contradicts that one?

Common sense :) You wouldn't create an ID which grows the number right? If you wanted it to grow, you wouldn't add the preceding 0's right? Would you?

In other words, you would keep it like "A1", "A2", "A234" or you would keep it like "A001", "A002", "A999". Does this sound sane to you? >> "A001", "A0010", "A00100". It would be perfectly allright, if the the "A00" part was something like "ATX" like a prefix :)

Hope I made some sense :)

This would work as long as the AgentId is a single digit number. But this will not work beyond that. For instance, your solution will generate "A0001" for AgentID = 1 and "A00010" for AgentID = 10 where as the expected result is "A0010". One less zero :) I think you should revise your solution.

That's indeed the correct answer. But just on a side note, this line below is not recommended practice.
<%#"A"+string.Format("{0:0000}", Eval("agent_ID")) >

You should change this to,
<%#string.Format("A{0:0000}", Eval("agent_ID")) >

The reason is that, string.Format uses string buffers internally to create the required string. But the use of "+" in string concatenation creates a memory problem (I know it's not significant here). Just as a best practice :)

@Manfred: I deleted it myself and posted this as an answer instead. Sorry about that :)

@BobJanova: The point is, in the hidden field, you can store the only data that you want to manipulate. For instance, what he wanted to put in the combo box. Where as, if you expose the session through ajax calls, there will be other information such as session id, flags set to check user levels, authentications, shopping cart info, etc. (in short valuable and restricted information).

So for a hacker, getting hands on the session means laying your website on a table for him to dine the way he wants. Simple example, you store the username of the currently logged user in the session. All he has to do is update the value to another username or simply iterate through all the values that is stored in the session. The possibilities are immense :) But yes, it will be dependent on what functionality he decides to expose :) But the hidden field approach is easier, simpler and safer. That's what I tried to say.

Btw, thanks everyone for the votes :)

I couldn't agree more :)

@voloda2: It depends on lots of variables, isn't it? :)
@SA: I saw you replying in quite some threads. Very helpful of you, but just on a side note, don't you think you are reacting to people's feedback a bit too much? This isn't a competition to help people and there are people like me here, who are not clever as you are. So please, bear with them.

All you have to do is google these individual things and you will get what you looking for. Give it a try.. Meanwhile, I will look to create a sample project for you, if I get some time.

All out of jokes. No one here will 'give' what you 'want'. I believe all you have to do is Google :) CodeProject helps developers those who are stuck, not who are lazy.

Do some work. Get back to us with your problem. Show us what you have tried and failed. Am sure everyone here will be more than happy to help you

What Tarun suggested is indeed the correct way to do it.

Just on a side note.. You can see how .NET adds controls to your form and what properties it sets, if you look into the designer.cs of a specific form.. If you don't know how to find that, just double click your form GUI, type the name of some control you have already added to the form and right click on it, and click "Definition".. This will take you there :)

Hope this helps
