If you can still solve your issue using sendkey, experts here at VBF will

Anyway to use SendMessage,
First, You need to have the handle of the VNC Window. To obtain the handle you use FindWindow() API. Then you need to use the FindWindowEx() api to obtain a handle of the chiledwindow. (The child window here is your Text Box Control). Bought of thease functions are explained in the MSDN.

Once you have the handles, you can use SendMessage API with the appropriate Messages to send the text to the control.
Cool, that sounds like the best way to go then. I knew there would be something better out there, just didn't know what it was called. Do you happen to have any examples of FindWindow or FindWindowEx?

I'll do some searching and see if I can find any on here, or through google too.
