Mike,
Check out ...
http://fox.wikis.com/wc.dll?Wiki~ShellExecute~WIN_COM_DNAHere 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
