Running a program within a program

ShellExecute is a good solution.

BOOL CreateProcess(
LPCTSTR lpApplicationName,
LPTSTR lpCommandLine,
LPSECURITY_ATTRIBUTES lpProcessAttributes,
LPSECURITY_ATTRIBUTES lpThreadAttributes,
BOOL bInheritHandles,
DWORD dwCreationFlags,
LPVOID lpEnvironment,
LPCTSTR lpCurrentDirectory,
LPSTARTUPINFO lpStartupInfo,
LPPROCESS_INFORMATION lpProcessInformation
);

Bingo, thanks

i want to run a program (a process) but that program should accept a parameter ( a user name and password ) how can i determine these parameters and send them after execution.

also after i run it and want to close it but it also require to accept confirmation using a message box.
