GetKeyState

[SLH]

Hi all, firstly i know that i can use the getkeystate command to detect whether a key is pressed i.e. if getkeystate(vbkeyup) < 0 then...

What i wondered is, does the value returned mean anything usefull? Values i keep getting are 0,1,-128,-127 and i can't see any connection with the state of the key it checks, apart from if it's negative the user is pressing it.

Thanks for any posts.

The return value specifies the status of the given virtual key, as follows:

If the high-order bit is 1, the key is down; otherwise, it is up.

If the low-order bit is 1, the key is toggled. A key, such as the caps lock key, is toggled if it is turned on. The key is off and untoggled if the low-order bit is 0. A toggle key's indicator light (if any) on the keyboard will be on when the key is toggled, and off when the key is untoggled.


I copied the answer from MSDN

High-order bit=1 means negative
High-order bit=0 means positive

Be warned - the key toggled bit is disabled under ME.

does this include win 98 too? Is there another way to check for the capslock?

[cookre]

Nah, the key toggled bit is disabled just in ME. That aside, that's the way to do it in 98.

This is what I get for GetKeyState, try this:
1 = ON
0 = OFF
-127 = 1 (ON)
-128 = 0 (OFF)
