Bruce,

A couple of more things. Can the test machine run the command in a regular old DOS window? The HWND and nShowCmd are not sent by reference. And your ShellExecute call you don't pass liShowCmd by ref. In my wrapper class I just declare the other args as string instead of string references, and pass object parameters without chr(0) terminating them. If you haven't downloaded spyin.zip from my website you might give the wrapper class a try just to see.
