problem with GetWindowText

[Viorel]

I have done:
1)found needed form with FindWindow
2)found an EDIT with EnumChildWindows
3)took text with GetWindowText
And as result I got nothing.
What I have done wrong?
P.S. Spy does the same.

You may have missed the last sentence in the description of the function.


<quote>
The GetWindowText function copies the text of the specified window's title
bar (if it has one) into a buffer. If the specified window is a control, the
text of the control is copied. However, GetWindowText cannot retrieve the
text of a control in another application.

So, where the sender and receiver are threads in different processes you
should send a WM_GETTEXT message (possibly after sending a WM_GETTEXTLENGTH
message) instead of calling the function.
