Can't Capture Ctrl-F4 in MDI Form

[PMGuy]

Hopefully, I'm missing something real simple in front of my face.


I've used the ProcessDialogKey override and I'm able to capture *most*
shortcut keystrokes, except for the one I'm really interested in.


It seems that the CTRL+F4 keystroke is being captured someplace before
my override can get it. Right now, because I can't capture the
CTRL-F4, the app uses ALT-X to close a MDI child. It works, but I hate

it.


What am I missing? Is there a setting someplace to force a MDI child
to execute the CLOSE() method? Does anyone know what is capturing the
CTRL+F4? I noticed a similar issue in VB6 that seemed to be related to

which types of controls had focus, but I couldn't actually duplicate
that in C#.NET.


Any help would be greatly appreciated.


NOTE: Here's the code that I'm using:


protected override bool ProcessDialogKey(Keys keyData)
{
switch (keyData)
{
case (Keys.Control | Keys.F4):
this.Close(); \\ NEVER FIRES
return true;
case (Keys.Alt | Keys.X):
this.Close(); \\ Used as a back-up to close form
return true;
};
return base.ProcessDialogKey(keyData)­;

NOTE: This is a duplicate post from the "general" group. I
cross-posted here because there seems to be more activity here. (I'm a
newbie)

I'm replying to myself for two reasons
1.) I'm hoping that "bumping" the thread prompts a response
or
2.) to conclude that my question is either too foolish to rate a
response or some undocumented M$ "feature" to which there is no
solution...

Have you set the KeyPreview property in the MDI child to true?

KeyPreview is set to true... with no change in behavior. :-(

What tool can I use to find out where the Ctrl+F4 is getting captured?
