How can I start other software within CVI

[MerryMay]

Dear sir:
I want to do the following works. First there shows a file-select popup. After a user select a file which its type is text file, the program starts Microsoft Word or Microsoft Notepad or some other word process software. Please tell me how can I finish such work. I mean what should I do if I want to start another software in CVI? Wait for your answer and thank you very much!

You can use LaunchExecutable() or system() functions: the last one wats until the program launched is finished and the returns control to CVI, while the first one returns immediately.
