I'm not sure of the exact syntaxe because I don't have Visual Studio .Net installed. But you can simply select the event closing (I hope it's this one). Then, in the event arg, you can simply use e.Cancel = true; to cancel the event, i.e. prevent the window close. Of course, you could also remove the "little cross" button.

First subscribe to the Closing event:

this.Closing += new System.ComponentModel.CancelEventHandler(Form_Closing);

Then use the CancelEventArgs.Cancel property to abort closing:

private void Form_Closing(object sender, System.ComponentModel.CancelEventArgs e)
{
e.Cancel = true;
}

Use the OnClosing event to do it.

private void Form_OnClosing(object sender, System.ComponentModel.CancelEventArgs e)
{
e.Cancel = true; //prevents the form from closing
}

private void Form_OnClosing(object sender, System.ComponentModel.CancelEventArgs e) { e.Cancel = true; //prevents the form from closing } This will prevent the form from closing ever!!!!! You do want the user to close the form somehow if not by clicking on the "cross"??

I would like to remind you that your users will expect to be able to close their windows this way. It seems to me to be a big violation of good GUI principles to proceed this way. I would suggest that it would be far better to disable (probably difficult) or not show the close box. In this way, your users won't be confused with the lack of function.

This is just a sample. I'd assume zecodela would know enough to put some conditional statements in there before setting e.cancel to true.
