Your information is very helpful. I have tried to retrieve control IDs for password fields in various mails like yahoo mail, gmail etc. through Spy++ tool. But I'm unable to find them. Can we get control IDs for every field through Spy++ or is there any possibility for the people who prepared the site to hide the particular information from Spy++? After a lot of trials I've got control ID for password field of Gtalk login dialog, but got empty string after sending WM_GETTEXT message. What would be the reason for it? I'm able to retrieve information of username field in the same dialog. It would be grateful if you can clarify my doubts.

Thanks in advance,
