On the other hand, you may call GetASyncKeyState whenever you need it.

According to MSDN:

The key status returned from this function (GetKeyState) changes as a thread reads key messages from its message queue. The status does not reflect the interrupt-level state associated with the hardware. Use the GetAsyncKeyState function to retrieve that information.

s it a strange way of telling me that GetKeyState() could give me a key-status that is actually outdated already?

GetAsyncKeyState gives the current state.

GetKeyState is useful for VK_NUMLOCK or VK_CAPITAL, which depends on toggle values

In my apps i use

GetAsyncKeyState(vk_shift)!=0

to find out if the shift-key is pressed.
