Hi,
After doing a bit of googling, it seems everyone refers to the article
"Managing Low-Level Keyboard Hooks in VB .NET" Written by Paul Kimmel - http://www.developer.com/net/net/art...087_2193301_1/
When I implement this in a VB.NET Windows Forms application in Visual Studio
2002, everything works fine - I can hook the keyboard, trap keys, etc.
When I take the same module and place it in my VB.NET Windows Forms
application in Visual Studio 2003, it all falls apart.
I set a breakpoint on the Keyboard Hook, which works fine.
But no matter where I set a breakpoint in the Keytrap, it never seems to get
called, and there's no output as usual in the Output (debug) window.
I've copied the code exactly as written in the article, and also tried
directly copying the code from the known-working VS.NET 2002 project .
Is there something weird going on with my application, or does everyone have
this problem in VS.NET 2003? 1 2619
Anyone able to help with this at all?

Is there a way via c# to hook a system tray application into the windows
keyboard que globally so that when the application is running and you

Please,
is there a way i can hook the keyboard? I would like to hook everykey.
CTRL+ALT+DEL, CTRL+ESC, and all others. The user just press some keys, and
none control keys, not only at my app but all windows.
A friend told me that there's a non-documented API that let me do this, but
he didn't remember the name.
Danke.

i created a control that hooks a keyboard to find out if a specific key is

The problem i have is that more than one instance of this control is running

When I try to hook a non letter key like left arrow (37) all is OK.
If (Hookstruct.vkCode = 37) Or (Hookstruct.vkCode = 83) And
CBool(Hookstruct.flags) Then
But, for example, the hook for the letter "s" key (83) does not work.
Mysteriously, the "s" starts hooking properly after I set and continue
through a break point. I can even then remove the breakpoint and the "s"
continues to hook OK as long as I have the debug session going.

Hello,
I have a Windows Pyhon-Tk app which need to capture mouse end keyboard
events even when the app is not in focus.
On Windows so far I've used the excellent PyHook which does the job
perfectly:
" The pyHook library wraps the low-level mouse and keyboard hooks in
the Windows Hooking API for use in Python applications."

I have an application that minimizes itself, and I want it to listen
for certain key commands, and when they are pressed, my program can
react to them.
So far I've gotten my application to react as I intend while the
program has focus, but when the application loses focus, the listening
stops.
I am using VS 2008 beta 2, with .net 3.5.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
