read the HKEY_CLASSES_ROOT\mailto\shell\open\command key. In may case (Outlook is the default email client), the value is "D:\Office\Office\OUTLOOK.EXE" -c IPM.Note /m "%1". Other clients will doubtless have different values. You could parse the text to get the execuatble name, or just check for the string OUTLOOK.EXE.

BTW, FWIW Mark, you don't need to check both VARTYPE() and ISNULL() - VARTYPE() returns "X" if the variable contains a .NULL. :-)

Cheers,

Andrew
