    Question readling listbox in another app

    This is kind of a repost. I wanted to go ahead and register.

    Thanks to the help I have received so far, I now am using FindWindow and FindwindowEx to get my listbox. The problem now is when I try and send a message it fails an IsWindow assert.

    I decided to bypass the Cwnd::SendMessage which does the assert and went with ::SendMessage which takes the hwnd asa parameter. This works, (doesn't give me an error) but does not return any usefull info.

    Code:
    HWND ChildWnd,Wnd;
    
    Cwnd *pParentWnd = FindWindow("Afx:40000:b...", NULL);
    ChildWnd=FindWindowEx( pParentWnd->m_hWnd,Null,"#32770",NULL);
    Wnd=FindWindowEx( ChildWnd, NULL, "ListBox", NULL);
    
    pDC->TextOut(1,1,(CString)::SendMessage(Wnd,LB_GETTEXT,0,0));
    This just prints a block character.

    Any further help would be greatly appreciated.
    Best Regards,

    Bonkey
