capture user id in remote desktop sign on screen

[gc dublin]

When starting remote desktop, sometimes the service will have user id already exist and cursor will go to the password field for you to logging from there, sometimes no user id entered, so cursor will be at user id field.

I need to have a way to see where the cursor is, if cursor is at user id then I send user id over, if cursor is at password, then send password over over only.

I used AU3Info.exe trying to see if I can get a control, but apparently it is not able to.

Does any one has done this before.

Thanks.
