Searching for password

Dear VB users,§

I am trying to find the password in Ms Word object. In a "do while loop" the
program is sending information to the textbox who is asking for the password.
Sending is done with the help of de function "SendKeys PasW, True".

When the correct password is filled in the textbox will disappear but the loop is
still running. I am in the object but I don't know the password!

Can someone tell me a system what stops as the textbox disappears.
I am thinking about the API "SendMessage" or "PostMessage".

Thanks for reading and hopefully helping.

Nice regards,

Michelle.
