No way...?
:confused:

Using GetKeyState
with the arg VK_CAPITAL ;caplock
Returns the state of the key without a window for me.

is this what u needed?

EDIT: didn't see a followup post when I posted this.

Hi,

iblis: GetASyncKeyState() kann only detect, if capslock or numlock key actually is pressed down or not.
RobotBob & CYDONIA: GetKeyState() only works, if the program window has the focus...

I could need something like GetAsyncKeyboardState()...
Any other ideas ?

Hook the keyboard and you will always have state information, regardless of focus.
Of course, you will need to SendMessage, for any state changes, to your window.

No, you misunderstand.



I was saying that, for me, that is not the case. I wrote up a test program and found that GetKeyState() works fine, and reports the state of the Caps Lock key without error, no matter what window I give the focus. For example, even with Notepad in the foreground, the test program was still reporting the correct Caps Lock state.

Hi,

I've tested the program under XP Home, and it was still reporting not the correct Caps Lock state, if the window had lost the focus... Without focus the window is still dead.
Can please another XP User test this ?

The source is not ready finished, I'm testing this an that.
It's part of a Dll function.
I trie to get all keys, the user is pressing system wide. Later the programm should be a textbuffer agains loosing data.

What about hooking the keyboard ?

Sorry for my bad english... :(

I created a dll that used the function GetKeyState .
I create another app WITHOUT a window, simple gui-free that calls
-my- GetKeyState dll function. It worked perfectly. There is no window
to get focus too.

So then I guess without further code or a description of what you are doing...

EDIT:
In your original post, you stated you wanted to find out whether capslock and numlock were active. But now I am thinking your trying to store all keyboard hits. Are you writing a 'key logger' ??

RobotBob.

That sounds like a cool programm.
I have (haven't we all) type something only to have the
web page expire or something.
