Problem identifying Window

[Jerry Thomas]

I am trying to grab text from a control - TVirtualTreeHintWindow.
The problem, there seems to be no parent window.

When I set the focus and then use GetWindowNames, the title is blank but the class is correct.

When I use View System Windows, I see the control (it matches the class from the previous comment) but it is under the top class.
This is what I get:

Code: Select all

65552 - #32769 ""
...
  396314-TVirtualTreeHintWindow


With GetWindowNames, title is blank.
But then if I use the returned handle and class:

Let>WIN_USEHANDLE=1

GetWindowText>WinHandle,rslt                  returns blank

GetWindowTextEx>WinHandle,rslt               returns blank

GetControlText>winHandle,winClass,1,rslt   returns ##NOSUCHOBJECT#

Any ideas?

One quick thought. Using GetControlText> what happens if you set the instance to 0. Wouldn't that make sense if this window doesn't have a parent? The error message ##NOSUCHOBJECT## indicates either a class or instance failure.

Code: Select all

GetControlText>winHandle,winClass,0,rslt

GetControlText>winHandle,winClass,0,rslt returns ##NOSUCHOBJECT##

This tells us the classname is "TVirtualTreeHintWindow" and there is no exposed window/caption text. You're using winClass as the class name.

See:

So GetWindowText will return nothing. GetControlText will return nothing. Your GetControlText has winClass as the class name which is why you're getting no such object.

The only things that *may* work are GetWindowTextEx, GetTextAtPoint or GetTextInRect. Specify coordinates for the latter or the MAIN window title for the former. GetWindowTextEx is really a wrapper for GetTextInRect - it focuses the given window, and gets it's screen bounds and then calls GetTextInRect with those bounds.
