I kinda asked this before, but now I really need the answer.

I need some source, small and simple, in Visual C or Delphi, that runs on Windows 2000, that disables the Windows key.

Thanks in advance.

Bit short for time, but you could:
hook the keyboard using SetWindowsHookEx(WH_KEYBOARD, ......),
and scan for the keycode for the windows-key ?

I started out that way.

First of all you use WH_KEYBOARD_LL and not WH_KEYBOARD.

Didn't work out too well though.

I managed to hook the Windows key and stop windows from seeing it, but the key doesn't release. Therefor any key I press after that becomes a combination of the Windows key and that new key.

This must be the right way to do it, but I need some help... some source.

A quick&dirty solution would be

char c;
// disable key
SystemParametersInfo ( SPI_SCREENSAVERRUNNING, 1, (void*) &c, 0);

char c;
// enable key
SystemParametersInfo ( SPI_SCREENSAVERRUNNING, 0, (void*) &c, 0);

(haven't tried it on Win2k)

In my opinion it should be the sollution, but MS removed it in windows 2000.

My guess is, to keep a stable OS.
Now any key pressed on a screen saver just returns you to the login screen.

So... Unfortunately it doesn't work on 2000.

Try using pretranslatemessage to capture the messages and then do nothing if the key Code is VK_LWIN & VK_WIN


Tell me if you need the code

Luck,

Sorry I only comment now.
I've been very busy lately...

I tried a quick test this morning on the PreTranslateMessage, but can't get it to work.

Could you send me some source please.
Just a Hello World.

Thanks.
