I'll have a look at this. Right now I am not using very many keys and
they all seemed to work. spell from cyclone is useful in doing keyboard
type patches. It takes text and converts a string to the ascii values. I
had to use upper case characters since your external only accepts upper
case ascii values  since that is how the key codes are defined. I didn't
want to get fancy yet and use shift etc. I think it would be great to
create an external that takes ascii characters directly. I think you can
then use vkkeyscan to convert to the key codes which your external
takes.

Have you looked at sendkeys . This could simpliy things as well.

I could work with either. I wonder is there is a way to direct the
keypress to the desired window (program) . Currently the cursur has to
be in the window where you want to recieve keypresses. Maybe using the
SetFocus http://msdn2.microsoft.com/en-us/library/ms646312(VS.85).aspx
or SetActiveWindow function you could direct the keyboard input to the
desired application? I can see that the feature request is growing : ) .
Congrats on writng your first external. I have yet to tackle one.
