Otherwise, you could use a separate WH_CALLWNDPROC and intercept WM_CHAR messages, which will have already translated the strokes for you. > How to react on keyboard key pressed fo longer time ( key > multiply - how much characters was sended) Again, something that a low-level hook is too low to handle. If you intercept a message hook to intercept WM_KEYDOWN, then you can grab the repeat count from the lKeyData value. Bits 0-15 of the lParam will contain the number of times the keystroke has been repeated from being held down by the user. > How to catch VK_INSERT ( check is overwrite or insert state ) The insert state is application-specific, not global in scope. When your DLL is injected into a new process, you will probably need to call GetKeyState() or GetAyncKeyState() insiode of your DllEntryPoint(), store the result into a variable that is unique for that instance of the DLL, and then whenever you detect a VK_INSERT for a given process, update the variable for the DLL instance that belongs to that process.
