Hi experts. I would like to know how to enumerate all the objects within a window. There is a certain program I am using that contains a value (the username) in a text box. So, I need to read that text box, and for that I need the handle. I have the window handle, but I don't know how to get the text box's handle. Is there a way to enumerate all the objects? I am quite sure this is possible since I saw some time ago a program that could say all the values inside text boxes.
Thanks a lot.

If you are using MFC, you can just say (CEdit Control Name)->GetWindowText(CString)

Oh, sorry, it now sounds like you are not writing the program, but are using it.  Hmm.  In that case I don't think it is possible to get handles to controls of windows that you don't own, so to speak.

is this application a external ie you don't have the source code for it ?
You can use EnumChildWindows to get a handle for the text box once you know the parent window's handle.
