I think 'Richard Matthew Stallman' is a fanatic and a paranoid but I appreciate the work done by Free Software foundation.To me he represents Karl Marx in the digital world,Marx has 'Das Kapital' and he has his fanatic ideals of Free Softwares and anti-proprietary goals.
Freedom is all about choice,a person should be free to choose free software or proprietary software or use them both.I prefer the term 'open source' instead of 'Free Software'.
The program below produces a message box and the msgbox remains there even if the program exits..it uses the dos command msg. However it can;t produce the effect which you can get by MessageBox API.But it's okay for simple messages.
#define BYTES 50
wsprintf(buff,"msg %s this is a test",user);
Another way as Ancient Dragon said is to execute an other program.One of the way to do it is hold the hex dump of the program which shows a msgbox in a buffer...and then write the buffer to a temporary file and execute it.
