Program Running in the Background

And also how do I use the lpszCmdParam in WinMain? (I need to convert what you pass by the command line into two integer values.)

To keep your program running, just don''t return from the WinMain function. I''m not entirly sure what you mean here.

if you dont create a window, it will only be listed in the ctrl-alt-del box (and other similar programs)

to grab the kb input, directx might be able to do that, or you could try hooking the system''s message proc. Writing a VxD will work, but that''s a little tricky (ie, 100% asm)

i use __argc/__argv (in msvc) for command line params, however, sscanf should be able to parse winmain''s command line, it''s exactly as was supplied on the command line, w/o any leading/trailing whitespace

RegisterHotKey.

although usually you''ll have a named event that one of the program threads wait on, and to kill the program you''d start it again with some command line argument, such as "-kill". the app would parse command line and if it sees that argument it will set the termination event. the other instance will then get the waiting thread woken up and quit.
