Cool. Thanks for the info, Richard :D

yeah, I'm not aware that this question is already 10+ years old. by the way, @AndréKraak why did you update a question of 10 years old :)

Maybe CP can come up with a section something similar to freelancer.com/fiverr/upwork that allows the request of "do the remaining work for me" or "do the research for me".

import re, then re.findall(r'\d+', datasource_string)

Try appending the character of single quote in front of the link, for example: cell.FormulaA1 = "'" + newsletter.Rows[rowIndex - 1]["Bezeichnung"].ToString();.

Here's the problem you mentioned: "it goes to endless loop". But you didn't include code how you do it that cause the "endless loop". The SQL code that shown in the question is not causing the "endless loop". you have to provide more details.

Basic printing with webbrowser is easy. but however, u have to be familiar with HTML first. you may refer [here] and [here] for webbrowser printing.

In my approach, I will encode the images as base64 data, then compose it as HTML doc. Then use webbrowser control or webview2 to print it. Or use Microsoft Edge to convert the HTML as PDF.

Oh yeah, may I attach (add-on) a hint to this answer :D, try `MessageBox.Show(path);` and see

I copied your question exactly and asked it at chat.openai.com. The returned answers provided by the AI has some insights. You may want to check it out :) You did not ask your question on any specific blocks of code. You're just asking for general advice and general insights. That's the answer that provided by the AI >> general advice and insights :)

Then you need to adjust the color depth. I have updated my answer above with the info of how to change the color depth.

increase the size, for example:
int newWidth = 999999;
int newHeight = 999999;
choose the size big enough to surpass 9MB

I have a portable ASP.NET web server called "CassiniDev", that performs this. It handled request and serves the page. If you're interested, u can go to it's github for the source code. here's the link to the github: https://github.com/adriancs2/CassiniDev

You are strongly recommended to use dynamic native HTML + javascript (AJAX) to achieve this. HTML + javascript are considered native to web development world, and it's much easier to accomplish what you need. dynamic native HTML + javascript (AJAX) can also be used in ASP.NET WebForms. Look for the demo pages of "LoadJavascriptTable.aspx" and "LoadJavascriptTable.aspx" for insights at my demo project at github: https://github.com/adriancs2/GridView-Html-Table

Here is the live demo: http://gridview.adriancs.com/

You can use webflow >> https://webflow.com

@M Imran Ansari, he is typing the wrong column name. "alloyName" is not existed in "show tables"

Yupe, this is potentially not a fix. But if the operation can always finished with this setup. Then it can be considered as a temporary fix :) At least the whole thing can move on at the moment :D

.NET framework does not has build-in function for doing this. Which ends up you need en external library.

How do you load the image into the img tag?

I have updated the answer which gives you a better hint. What you need to do is apply the logic in your mvc.

Use combobox, you can only select 1 option in dropdownlist. (unless you use some jQuery, that would be a little more complicated.)

Try download "Microsoft Access Database Engine 2010 Redistributable", if your project still fail to locate it, try change your project to .NET 4.0, not 4.5

Are you trying to read Microsoft Excel Documents?

Javascript can do that

don't use Crystal Report. you will have a few issues when the technology evolves. Generate a html report instead. This will have much more compatibility, less dependency, less error and less problem.

dont use crystal report, generate a html report in stead.

If you need 2.5, then use NumericUpDown.DecimalPlaces = 1; NumericUpDown.Increment = 0.5;

using "" is creating an instance of string each time, but String.empty is not.

Sounds good. Thank you.

Hi, I don't have the privilege to use Windows services as the asp.net is hosted on a web shared hosting.

Did you actually google?

He want to do it at client side, at runtime. Not at visual studio.

Well, I can't see your computer screen and unable to guess the error message. Therefore I'm unable to tell what is happening to your project.

You code has no error. The error is coming from the invalid values. There are so many values in your code, I don't know which of them have error.

Check the following values are valid or not:
- txtEmail.Text
- fileName
- folder + fileName

Try catch the error like this and find out the error.

try
{
// ... perform your task
}
catch (Exception ex)
{
Response.Write(ex.ToString().Replace("\r\n", "<br />");
}


It is up to you to decide, you can Server.MapPath("~/" + "anything anywhere anypath and any name");.

Thats right, just ask the developer of that machine.

What shield? can it resists sword attack?

Good question

Rinjdael Algorithm in C# is actually encrypting byte arrays and return encrypted byte arrays too.

Basically,

To encrypt text, the text is converted into byte arrays and pass to rinjdael to encrypt, then convert the encrypted byte arrays into base64 string (text).

To encrypt file, the file is loaded into byte arrays and encrypted by rinjdael, then the encrypted byte arrays is written into file.

for webform asp.net, you can use FileUpload.

For this situation, you'll use UPDATE.

If the data is already existed in database and you wish to update it, you use the UPDATE statement. If you want to insert new data, then you will use INSERT statement. These are the very basics of MsSQL, try google it for tutorials. You need to learn the basic first before doing anything further.

by executing INSERT, UPDATE and DELETE of SQL statements.

database = SQL database = SQL table
are you referring to System.Data.DataTable?

If I understand correctly, after an ASP.NET page life cycle ends, IIS will release/dispose every object called within the thread, and this subsequently will close and dispose SqlConnection too. But I agree that, we should close the connection as soon as possible.

the above code shows no problem

Just press the trigger on the Barcode Gun and fire the laser. The barcode gun will return a line of text that it read from the bar code. There is no special configuration for the barcode gun to work. It is standardize. It works just like a keyboard input. You can assume that the gun is a keyboard. Unless you are using old type of barcode gun, then you will need the manufacturer driver/API/Plugin Library/etc. By the way, the device is normally called Barcode Scanner in English.

I have update my answer above to provide the correct information.

I have written an article of connecting MySQL from SilverLight by using web service.

Oppss, sorry I have provided one wrong information. xD
You are right. It's glad that you have figured out.
The example provided in my answer is for a ASP.NET page accessing the web services. XD
For SilverLight, the result is returned in event GetDataCompleted. ^^
But anyway, I think you have learnt something new by yourself, which is a good for you. Congratulation.

I always use BackgroundWorker to perform these tasks.

Something is wrong before this code. We can't tell what is wrong without seeing the codes before this.

I see. There are some hidden information which is not provided yet.
I can't guess what is your code's error in other part without seeing the code.

Yes, what RLH68 mentioned is correct.
By creating a static object of (UserInfo)Session["user"] can avoid the typo error.

+5 for not storing files in database.
This is because it increases the burden when backing up and restoring the database.

Can the user obtain the real filename on server?
example: www.myweb.com/files/--guid--

One way to protect the files to be direct accessed by user is to put them inside App_Data folder for ASP.NET. Use web respond to transmit the file for user to download.

He wants to store the uploaded files in folder, but don't want the files to be downloaded directly by other user.

This is a hot question.

insert into `table_name`(`richtext`) values('" + richTextBox1.Rtf + "');
richTextBox1.Rtf = select `richtext` from `table_name`;

the full code is not posted. in stead of giving you full baked code. This is actually good for you. In this case, you will learn more. It trains you to observe and train your programming logic. But, if you still fail to analyse the codes or integrate your code, you are welcome to leave comments and request for further help or further clarification.

this

AllowUsersToAddRow = false

can avoid calculation errors, which an empty row will not exist, but it also lost the ability to allow your user key in data dynamically/directly into datagridview. However, to allow or not. Its up to you.

and I also show you the extra code about the idea of using

int.TryParse()

you have missed the point.

I do not provide full solution, in stead, I give you a very important clue/hints about what is causing your problem.

Your problem is your code is taking the last row into calculation. In your case, you have to check the last row is NEW ROW or not. because last row is always contains no data. Therefore, you have to use this

dgvr.IsNewRow

to by pass the last row, which is also the empty row. Then your calculation shall avoid any errors.

for the rest of the calculation. You are good to do it yourself without me showing the codes.

richTextBox1.Rtf = // data from mysql

I know this problem is solved.
just to share a bit idea.
does this solve your problem too?
at the load event of MessageBoxForm, add this:
this.Activate() or
this.BringToFront() or
this.TopMost = true;

Hi, I'm interested in async pages. Isn't that all page served in IIS/ASP.NET are treated multithread?

Can you give me some clue about what is async pages?

void CheckBoxList1_SelectedIndexChanged(object sender, EventArgs e)

ListBox1.Items.Clear();
foreach (ListItem li in CheckBoxList1.Items)
{

To the best advise for beginner of ASP.NET

ASP.NET is a technology that built on top of HTML, CSS and JAVASCRIPT.
Before you start with ASP.NET, you must get your feet wet into html and css.

have some patient, read all through the topic about html at here:
http://www.w3schools.com/html/default.asp

then read all the topic about css at here:
http://www.w3schools.com/css/default.asp

then try to have some understanding of Javascript at here:
http://www.w3schools.com/js/default.asp

Without the knowledge of these 3, you will feel that something seems to be missing and you can't really perform.

ASP.NET can be described as a dynamic html generator. At the mean time ASP.NET runs processing logic in behind, it also generates HTML document and transmits it through internet to your client. And Javascript helps to process logic at client's computer. Javascript can dynamically generates or change the HTML at client's computer too. Javascript also helps to collect data from client and post it back to server for C# to process data.

Understanding HTML, CSS and Javascript will help you to understand the life circle of website better. You will eventually find that, ASP.NET do not fully generate all the HTML for you. Some of the parts will still require you to write HTML syntax manually. ASP.NET will help you combine the HTML syntax.

After that you can start to learn ASP.NET.
Here is a very good book for you to start off as a beginner.
A very nice book to read: Download this:

Hi, your question asked that how to do it without a button. So which means you know how to do it if using a button?

by the way, if you declare the CheckBoxList1_SelectedIndexChanged event in ASP.NET page like this:

<asp:CheckBoxList ID="CheckBoxList1" runat="server" AutoPostBack="True"
onselectedindexchanged="CheckBoxList1_SelectedIndexChanged">

You don't need to declare it in code behind:

protected void Page_Load(object sender, EventArgs e)
{
CheckBoxList1.SelectedIndexChanged += new EventHandler(CheckBoxList1_SelectedIndexChanged);
}

and if you do it in code behind, you won't have to do it in ASP.NET page.

Oh, I finally got it.
to use formatted code block in comments, use
<code></code>

Yes, as richcb code presents
this is not needed:

else
{
TextBox1.Text = "";
}


I see others use formated code block in their comments. Do you know how to do that?
Example:
<pre lang="cs">string a = "hello";</pre>
see, the html is not rendered.

by using update panel?

Hi Chiklu Soumya, I didn't mention RadioButtonList in my answer.
Your code is almost there. Its just has a little bug.

It should be this right?
<pre>TextBox1.Text = RadioButton1.Text;</pre>
not this
<pre>RadioButton1.Text = TextBox1.Text;</pre>

I believe you can easily find lots of answers in google, even with graphics illustration and movie guide in youtube.

Hi, can you paste the codes that you have tried? You can paste the code in your question. Just edit the question.

Hi, can you show me what are the codes that you have written so far? You can paste the code in your question. Just edit the question.

To understand the need of doing this,
Try execute this:

string name = "anyname";
string address = "anyaddress";
string comment = "anycomment'); DROP TABLE IF EXISTS `table`; SELECT ('surprise";

SqlCommand cmd = new SqlCommand("insert into table (name,address,comment) values('" + name + "','" + address + "','" + comment + "')", cnn);

It's called SQL Injection.

for rapid change, cache the last existed largest number.
for slow change, compare the values one by one, or
sort the values and get the 1st or last.

spam...

Well, then change the engine, and it will. XD

save it as a html table file and name it with a file extension of ".xls".

whats the different between
<pre>public static readonly string SomeStr = "abcd";</pre>
and
<pre>public const string SomeStr = "abcd";</pre>?

So?

When do you want to find the control?

You create a template in Crystal Report.
then, you'll declare an instance of crystal report in code, fill in the values dynamically and export the PDF dynamically in c#.
All of this is done in code behind. Only the design time is done in visual studio's CR editor.
You can even generate the template in code behind too.

What have you tried?

You are recommended to post a new question for this. You will receive better solutions.

I don't understand your question.

What have you tried? What have you done? Show some of your code.

Yes, it works.

Which of the line of code that you don't understand?

Hi, I have updated the answer.

You can ask someone to create the application for you at www.freelancer.com
There are lots of folks ready to create any application for you, with or without source code.

How about copy the data source file?

someControl.BackgroundImage = Image.FromFile("C:\\someimage.jpg");

check if the values exist in data or not.
if yes, throw error
if no, add it.

There are many databases that you can use.
do you want recommendation?

that will do

use 2012

I guess he missed the last sentence: How to do that?

select * from table1 inner join table2 on table1.someid = table2.id;

data.GetType().ToString()
what do you get?

If it is disturbing your b, then you can make it out a or out c or out anything you like.
By this, it won't affect your b.

Maybe you are trying to ask:
How to make a thing that support uploading and downloading both music/video through internet (online) in C#?

You can do that with www.mediafire.com
That enables you to make any media/files online where you can upload and download.

Thanks for information.

Hi buddy, you forgot to accept solution

Are you encrypting unicode characters? Maybe you have used the wrong Encoding.

Can you show the codes that you build table1, table2 and gridview?

textbox can be wrapped (the output of the employee name) inside an updatepanel. This can prevent a full postback. Slightly better performance.

Yes, this query will return an integer.
