Invoking another programm from C++ code! 1

[Dhafir]

Hi all,
I need to invoke another programm written in C++ (works as a utility to the main program).
I need to pass in parameters to the other program when I invoke it and wait for a return value.
How can I do that please?
I know there must be a function call to invoke another program and a way to get a return value from it.

Thanks for any help

ShellExecute()
ShellExecuteEx()

Hi Dhafir.
There are a few ways of doing this. If the program is a console application, try 'spawnl()' functions.
'ShellExecute()' and 'ShellExecuteEx()' could be used as well as 'WinExec()' functions in a Windows program, but the prefered way of control is by using the 'CreateProcess()' function. This can be used for either console or window process creation.
