How to Proceed without Waiting for the Completion of a Sub-task?

[tom_c_lin]

Hi Everyone,

My program makes the following system call to start a sub-task, i.e., run prog.exe.

prog.exe datafile.dat

The calling program always wait until the completion of the sub-task before it proceeds. Can any of you show me how to make the calling program proceeds without waiting ? Thanks in advance. Good Day.

Try ShellExecuteEx. I would have posted some code, but I have just found that 
I cannot paste anything into this blasted window!

Hi Tom,
Try executing (through SYSTEM)
'start prog.exe datafile.dat' (which launchs a separate cmd shell window)
or
'start /B prog.exe datafile.dat' (which doesn't, useful for windows GUI app)

Example of ShellExecute

You can paste with CTRL-V or the Paste icon in the editing toolbar (third from left in bottom row.) For pasting code, use the icon on the far right of the bottom row.)

Thank you all for prompt replies. The command 'start /B' is what I am looking for. Because our programs are triggered by activities on Sun, we have to use Window Service. Creating a window to run will not work. Thanks again. The forum has been extremely helpful to my project. I really appreciate that.
