if(result == 1)
{

ScriptManager.RegisterStartupScript(this, this.GetType(), "RunCode", "javascript:alert('Student Details Added successfully');", true);

}
else
{
ScriptManager.RegisterStartupScript(this, this.GetType(), "RunCode", "javascript:alert('Record already exists');", true);
}

con.Close();

}


}


try this I have not compiled. I think this will work also I jave not check your alert code. Are you sure ScriptManager.RegisterStartupScript(this, this.GetType(), "RunCode", "javascript:alert('Student Details Added successfully');", true); this code is running

Ok forget the primary key. as I understand it is urgent. Use this

public int Count()
{
string query = "SELECT Count(*) FROM StudentDetailsTable where RollNo = '" + TxtRollNo .Text + "'"; ///add other columns
int Count = -1;

//Open Connection
if (this.OpenConnection() == true)
{
//Create Mysql Command
MySqlCommand cmd = new MySqlCommand(query, connection);

//ExecuteScalar will return one value
Count = int.Parse(cmd.ExecuteScalar()+"");

//close Connection
this.CloseConnection();

return Count;
}
else
{
return Count;
}
}


if this count bigger than 0 run javascript alert code else make insertion.

I understand but here is the thing When you say same record what does it mean. It is all values are same or not?.

Can you be more spesific about what you need. If you are, I can help as much as I can

I do not understand what you need but as you must create a button or link button to download and when this clicked you can get the name from its item index and give the link or write the file. If you exatcly tell your problem I can be more helpful.

Sorry It is my bad also sorry for bad english. Here is the thing when you bind checkbox items like CommandArgument='<%# Eval("AssignedTo") %>' you just get the value and embed into it. Container.ItemIndex means you get the index of item. So when you add name='<% "checkbox" + #Container.ItemIndex %>' it means in the first item the combobox's name attributes becomes checkbox0 and in the second it becomes checkbox1(If you add this into checkbox). When you add this to linkbutton and if you add this like name='<% "linkbutton" + #Container.ItemIndex %>'
the first item's linbutton's name attribute becomes linkbutton0.

So when you add onclick event to checkbox, on the javascript you can get name attribute of sender. For example if you click first checkbox, you will get name attribute as checkbox0. So by this way you will know, first checkbox clicked so you need the component whichs name attribute is linkbutton0.

To be able to handle this component you will use for example document.getElementsByName("linkbutton0")[0]. So this elements value is your userid.

Is everything ok?

Is it just green color or also their variances?

Sorry it is my bad but you said GridView yet in Windows Application it is DataGridView :). For it
yourcolumn.DefaultCellStyle.Format = "n2";
yourcolumn.ValueType = GetType(double);

I think it is something like that

Can you be more specific ?

Is it appropriate :
string s=string.Format("{0:0.00}",doubleValue);

It is also about size and other limitations. Here is the answer: http://msdn.microsoft.com/en-us/library/ms143432.aspx I think you are using MSSQL

When you say "I want to scroll the label from top to bottom and from bottom to top", did you mean that I want scroll label from top to bottom pixel by pixel and when it reaches the bottom I want scroll it to the top pixel by pixel again ?

Yes you can but you must create a way to create combobox and others with your ids. If not you will not know the id of an component and you will not reach this pbject via javascript.

Hi,

Here is the thing. You should use HKLM because you want access for all users. If application will not write anything. you can read from hklm without admin rights and the good point is that as I know, by using trusted installers setup do not need admin rights to write to hklm. I'm using it now but I did not check it for all kind of users. I'm using Inno setup and also setup project also will be ok.

Another thing is HKLM keeps lots of com data and operating system data. you must select a path in hklm which is not used before to avoid to break any other data.

how did you redirect to inner pages. There is no difference with Response.Redirect and coping url. Am I wrong ? Did you mean anything else?

if you mean word document you can look here:

if not, what dou you mean with document

Thank you for your response. I have never faced a situation like this. As i know Network Service alredy have these permission. I'm happy for you to solve your problem.

Thank you

you may configure it by changing web config:

hi,

I completely understand your problem. haar cascades algorithms are used for generally detection. For example if you try to find a person in a picture the most basic way you can is with haar cascades you can find this man's face and get that part then with template matching you can check he is or not.

So if you research the idea of haar cascades algorithm it just find the object which similar to your training and is generally more succesfull for more 3d objects but leaf is more close to 2d. a template matching algorithm can be more successfull compare to haar cascades.

Another important part is your positive images. Namely in what kind of pictures you will search leaves. As i understand according to your picture sharing i use edge detection and after that template matching or block matching.

please share your test cases and you can read haar cascades algorithms, hu moments edge detection template and block matching.

maybe it can give you an idea:
http://www.tiobe.com/index.php/content/paperinfo/tpci/index.html

I used haar cascades algorithms almost 1 year for animal face recognition. The best option I think is opencv. In this package everrything is ready and you just need cascades training which negative( images do not contain your object for recognition ) and positive ( images contain your object ) images. There are several sites they have lots of negative images. If you need we can find for you. One of the problems is you need lots of positive images.

Main idea of haar cascade algorithm is it collects this data and according to your rectangle choices(generally 16 x 16 or 24 x 24)it creates data collection and according to these collections it recognize what you want. These pixels (16x16 or 24x24) are not enough your detailed recognition. Namely in this situations coded haar cascades algorithms can not realize the differences between two different kind of leaves. Baceuse these algorithms generally used for real-time recognition.

If you create your own haar cascades algoritm with bigger and bigger windows like 512 x 512 it may help to solve the problem.

The question is here do you know the unique properties of leaves.

Keep me informed.

Instead of nested gridview you can use nested repeater. Because it is easy to manipulate and change.

Why do not you just insert and use your query with order by Name asc

Haar cascades and face recognition all them is a kind of machine learning. In face recognition actually you collect some datas and according to this data the algorithm can decide whether it is face or not.

To be able to do what you want needs collect images of spesific leaves.
Also haar cascades is best at colored images not at gray-scaled images.

Firstly you must determine unique properties of leaves. For example if the main vessel's shape (I do not know its academical name) you can use block matching or else but I think haar cascades can not achieve this because haar cascades run based on the depth differences.

Once upon a time i used haar cascades for animal face recognition but cows and horses' faces are so similar for haar cascades so it can not recognize correctly.

Sorry for bad english

ok use gvInbox.DataBind(); instead gvInbox.Page.DataBind();

I think you have a problem with pagersettings because there is no closing tag, It might be problem but I can not see any wrong part for this problem. Can you share your codes after correction of pagersettings tag

Can you share Page_Load?

Did you look at IIS session timeout value for your website
