By the way, I DO recive WM_KEYDOWN within the EXE part of my app; That's DLL has sent it correctly!

PostThreadMessage(g_dwThreadID, WM_KEYDOWN, lParam, wParam);

When a key is pressed any where in the system, the DLL catchs it, but with
a little information about it (that's almost a bare virtual-key as wParam).
Now It's my turn! I send this recived messages to the EXE using
PostThreadMessage, like this :

PostThreadMessage(g_dwThreadID, WM_KEYDOWN, lParam, wParam);

My goal is to design a system-wide keyboard hook. This app. consists of two parts:
1) An EXE file with one sigle thread ended in an ordinary message loop.
2) A DLL that installs the keyboard hook.

When a key is pressed any where in the system, the DLL catchs it, but with
a little information about it (that's almost a bare virtual-key as wParam).

The problem is how to translate a virtual-key into an Ascii or Unicode value, not where to do that.

Please direct me to the right way on translating a virtual-key into it's equivalent in Ascii or Unicode!
