GetWindowText and an edit control in another application

[Daniel Grafe]

I want to rerieve the text of an edit control in another application. I do
have a handle to the edit control but "GetWindowText" doesn't work. It does
work if the edit control already has a text after creation. Text typed by
the user can't be retrieved with GetWindowText. Is there a possibility to
get the Text of the edit control?

Thank you....

You must explicitly use SendMessage and WM_GETTEXT to do that across process
boubdaries. Only SendMessage does the behind-the-scenes marshalling
required.

Close but not quite - GetWindowText() will retrieve the text set for any
window in the system - but, for windows in other processes, it retrieves it
directly from the windows internal WND struct. The text in the WND struct is
set by CreateWindowEx, and changed by allowing DefWindowProc() to handle
WM_SETTEXT messages. Any window that overrides WM_SETTEXT (such as EDIT
controls) will thus defeat a cross-process GetWindowText call.

Let let him decide if it works for him.

SendMessage and WM_GETTEXT works fine for me. Tank you for your help.....
