"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Use the parameter you would use for ShowWindow: i.e. SW_SHOWNORMAL.

Heres a way to start a program and either wait for to complete or continuing with the main process:

/************************************************************/
/* Execute a (DOS) command string or start a windows module */
/* The flag 'waitforit' causes the parent program to wait   */
/* until execution of the child completes if it is true.    */
/* otherwise the child is started and run concurrently.     */
/* The funtion returns the instance handle of the child.    */
