Mike,

Check out ...

http://fox.wikis.com/wc.dll?Wiki~ShellExecute~WIN_COM_DNA

Here is a code snippet from an old UT message (can't remember the author) ...

DECLARE INTEGER ShellExecute IN SHELL32.DLL ;
INTEGER nWinHandle, STRING cOperation,;
STRING cFileName, STRING cParameters,;
STRING cDirectory, INTEGER nShowWindow
ShellExecute(0, "", "mailto:" + lcEmail, "", "",1)

I'm sure there are some better examples in the FAQ section of the UT. Search on ShellExec and/or Ed Rauh.

Good luck!
Malcolm
