you've done this before
Cheers - I was tearing my hear ouit at that one, I really should learn this API stuff properly

No worries mate...

[VBShipWreck]

get the hwnd of the edit control and send WM_SETTEXT to set the password. you could make it also login automatically, find the button hwnd and send WM_LBUTTONDOWN or whatever
