all right, I understand. I tried with WinExec and there was no problem... with ShellExecute im doing something wrong: ShellExecute(0,"open",exefile,params,0,SW_FORCEMINIMIZE); Do i have to put a handle different from NULL? I have no window handle in the function which muss call "ShellExecute". Whats wrong? Thanks, Elale.

Hi, Jungs, I´m trying to execute an exe-file from my own programm. I tried to use th _exec-family functions, but it didn't work. The executable is a console programm, so i need to be able to pass some parameters, too. Thanks. Elale
