I created a simple Windows Form in a C# project.
I created a KeyDown event:
private void Form1_KeyDown(object sender, KeyEventArgs e)
if (e.Control && e.Shift && !e.Alt && (e.KeyCode >= Keys.D0 && e.KeyCode <= Keys.D9)
I set the KeyPreview property of the form to "true".
CNTL-SHIFT-1, CNTL-SHIFT-2, etc work just fine.
However, CNTL-SHIFT-0 does not. Form1_KeyDown() event is never called.
I've never experienced this odd behavior before.
Thanks, in advance, for your help.
