Re: Filling web site page values from our(local) database values.

If you use a webbrowser control, you may be able to interact with it in code to populate values.

none of these, they are all useless to you.

You need to host the site in question in a web browser control, then find a way to modify the content within that page. I am not sure exactly how to do that, but it's the only way.

Accessing Win32 windows handles/pointers from a C# application/form

I'm not sure how your question makes any sense. You request a file, it gets copied into memory and then written to your file system.

All, I am new to the C# world and I am having some difficulty in finding information on the following.

Is it possible to gain access to a Win32 window handle or CWnd pointer from within a C# application/form. Basically, I would like to use a C# form (or other construct) to simply house an already existing OpenGL window class written in C++. I would like to maintain all functionality already built into the C++ derived, 3D/OpenGL Window object.

Any information and/or direction to other sources would be greatly appreciated
Thanks in advance,
Michael

Hi,

I would like to know how to prevent the TextChanged event of a ComboBox from firing. For example I have a ComboBox with 2 values 1 and 2. So I change from 1 to 2 which results in the TextChanged event getting fired but before the TextChanged event completes I want to cancel it based on some condition. I was wondering how can this be done. Also cancelling of the TextChanged event should change the currently selected value in the Combobox to 1 instead of 2 since the TextChanged event did not complete.

I am using .NET 2.0 Windows Forms with C#.

Your help is greatly appreciated.

Thanks.

In the TextChanged event or the SelectedIndexChanged event write the following code.
check ur condition and if true then
e.handled = true;

this is return that event without further processing.

Hope that works for you,

Thanks & Regards,
Pramod

I have this assignment m_strFileName = OpenFile(); in which there is a try/catch block within the OpenFile method.

 private string OpenFile()<br />
		{<br />
			string strFilename;          	<br />
<br />
			if (intStoreNumber == 201)<br />
			{<br />
				strFilename = "t1";<br />
			}<br />
			else if (intStoreNumber == 202)<br />
			{<br />
				strFilename = "t2";<br />
			}<br />
			else if (intStoreNumber == 203)<br />
			{<br />
				strFilename = "T3";<br />
			}<br />
			else<br />
			{<br />
				strFilename = intStoreNumber.ToString();<br />
				strFilename = strFilename.PadLeft(2,'0');<br />
			}<br />
<br />
					<br />
			strFilename = "afford" + strFilename + ".dat";<br />
			try<br />
			{<br />
				File.Copy("F:\\BORIS\\" + strFilename, Environment.GetFolderPath(Environment.SpecialFolder.Personal) + "\\" + strFilename,true);<br />
			}<br />
			catch <br />
			{<br />
				MessageBox.Show("The file " + strFilename + " can not be found. Please check " +  <br />
					"that you selected the correct store and that your network connection to" +  <br />
					" drive F: is not disconnected","File Not Found", MessageBoxButtons.OK,<br />
					MessageBoxIcon.Exclamation);<br />
				<br />
			}<br />
				strFilename = Environment.GetFolderPath(Environment.SpecialFolder.Personal) + "\\" +  strFilename;<br />
				return strFilename;

The question I have is if the program runs into this exception, how do I return it back to waiting on an event versus going through to the next method?

Everything I got from google tells me all about the structure of a try/catch/finally block, but nothing much more on how to exit gracefully without shutting down the program.

Thanx in advance.

why would your program shut down?
you have handled the exception and displayed a message box, the user will click the ok button on the message box and the program will continue further.

Can you please elaborate your problem?
what actually do u wanna do?

Thanks & Regards,
Pramod

I do not want the program to shut down. The method that is called returns a value that must be used in the next step of the program. But since the exception was thrown, I do not want the program to progress to the next called method. I want it to kill the forward progress and have the app wait for an event.

Thanx for the reply!

jsut make the following changes

try
{
File.Copy("F:\\BORIS\\" + strFilename, Environment.GetFolderPath(Environment.SpecialFolder.Personal) + "\\" + strFilename,true);
strFilename = Environment.GetFolderPath(Environment.SpecialFolder.Personal) + "\\" + strFilename;

}
catch
{
MessageBox.Show("The file " + strFilename + " can not be found. Please check " +
"that you selected the correct store and that your network connection to" +
" drive F: is not disconnected","File Not Found", MessageBoxButtons.OK,
MessageBoxIcon.Exclamation);
strFilename = string.Empty;
}

return strFilename;

and when u call the method OpenFile()
just check if the return string is Empty or not
if it is empty string dont do any thing else process furhter.

Hope that is what you want to do...

Thanks & Regards,
Pramod

Thanx for the reply....but how do I stop the execution of the code? It is withing a button's click event.
I would supply the code, but it is on my work desktop and I am at home.
break
would not work because it is not within a loop, etc

what do u mean by stop the execution of the code.
You just have to write the code in the IF block,,, if the string is not empty perform what ever you want else nothing...

e.g.
if(!String.Equals(String.Empty, Openfile())
{

///DO WHAT U WANT DO

}
else
nothing will happen....
Is that fine?

Thanks & Regards,
Pramod
