Trapping Enter key?

[Dave Veeneman]

Is there a simple way to prevent the system from beeping when I hit the
Enter key in a single-line text box?

I'm trapping the KeyDown event to intercept the key press and advance the
focus to the next control. But I still get an annoying beep. Any way to
silence it? Thanks

Here is an example to capture the enter key.

protected override bool ProcessCmdKey( ref Message msg, Keys keyData )
{
if( keyData == Keys.Enter )
{
MessageBox.Show( "Enter pressed!" );
return true;
}
return base.ProcessCmdKey( ref msg, keyData );
}


Hope this helps

Here's the code for the derived TextBox I created. It doesn't beep when the
Enter key is pressed. Instead, it advances the focus to the next control.


public class MyCustomTextBox : System.Windows.Forms.TextBox
{
protected override bool ProcessDialogKey(Keys keyData)
{
if (keyData == Keys.Return)
{
SendKeys.Send("{TAB}");
return true;
}
else
{
return base.ProcessDialogKey(keyData);
}
}
}


The code is based on
http://www.syncfusion.com/FAQ/WinForms/FAQ_c94c.asp#q915q, items 27.11 and
27.15.
