Does anyone know how to attach a file and set the message text through the ShellExecute command. This is the Code I have so far:

Code:
Success = ShellExecute(0&, vbNullString, _ 
"mailto:[email protected]?subject=Subject Goes Here", _
 vbNullString, "C:\", SW_SHOWNORMAL)
This command works fine, but I cant figure out what
parameters will set the message text and attachmet files.

Also is there a way to automate this so the user does not
see the default email client, it just sends the message out

Thanks in advance
