This would probably not work. You need to set a system hook with
SetWindowsHookEx, and trap all the events that can result in task
switching.  You would also want to handle Ctrl+Esc and double-clicking
on the desktop, which bring up the Task List dialog.

I have had a great deal of success with the following code (in bp7.0 but it should translate 
easily concept wise to C )

Procedure TPassword.WMSysCommand(Var Msg : TMessage);

Begin
  With Msg Do
  Begin
    Case (WParam And $fff0) Of
      sc_TaskList         : Result := 0;
      sc_NextWindow       : Result := 0;
      sc_PrevWindow       : Result := 0;
    Else
      DefWndProc(Msg);
    End;
  End;
End;

This issue has been addressed alot lately, it seems.  I'm running NT, and using
VC 2.0.  One approach which did NOT work for me was someone suggested handling
WM_SYSCOMMAND and filtering out SC_NEXTWINDOW, SC_PREVWINDOW, and SC_TASKLIST.
(for getting ctl-esc, also).  This absolutely did NOT work under NT.

Petzold (for win 3.1 of course) suggests grabbing WM_SYSKEYDOWN, WM_SYSCHAR,
etc.  Also a complete flop under NT.

I have seen mention of a "System Accelerator Table" which acts on keys before
they ever get to the application's accelerator tables.  Is there a way to
selectively disable translation of alt-tab in this system accelerator table?

Also, the online help would lead one to believe that Using SetWindowsHookEx
and just capturing your window's messages, using the message filter callback (
or something like that) would be enough to grab ALT-TAB.  Now, I compiled the
hooks example in the win32 samples directory, and ever THEIR example code did
not trap alt-tab where it claimed it did.

The one thing I haven't tried is the DLL SetWindowsEx Approach to trap all
system message traffic.  It seems pretty promising, but I've had such a lack of
success with all of the other "tried and true" methods that I didn't want to
waste any more time (outside of posting long, whiny followups :-) ).

SO, the $64 (or ~48 pounds sterling, as I could use some help from the UK also, 
if available) is this:  WHAT absolutelt, positively works for disabling alt-tab
for windows NT applications in the VC 2.0, MFC 3.0 environment?

Thanks, 
Dave

Take a look at HOOKS in Microsoft's Win32 Programmer's Reference Volume 1

There is an example of a keyboard capture program located on the 
Microsoft Developer CD Number 6 called sendkey. This may be of
some help.
