>When I was creating About dialog window, I wanna the user could press the underlined e-mail addr. to give me a e-mail to keep in touch with me ! But how can I do that!

Assuming that a MAPI client is installed, you can use ShellExecute() to start a mail message; or even the following:

oShellObj = CREATEOBJ('Shell.Application')
oShellObj.Open('mailto:edrauh@earthlink.net')

which would start the user's default mailer and create a message to me; you could substitute your own email address pretty easily. You'll want some error handling in case there's no MAPI client installed.
