I am trying to create an IDE like the Visual C++ IDE, and
I have a docking controlbar window derived from CDialogBar that contains a few controls that I want to dynamically size AFTER I undock the DialogBar(I derived a class that allows it to be resized, scarfed from the MS Developers Network). This is much like the file/class/resource/info list on the left of the Visual C++ IDE. The problem is, it never gets WM_SIZING messages, unlike the VC++ window, which does get them. Why not? Our window styles(via spy++) are exactly the same, save for a 0x001000 addition on mine, and a 0x03300 on theirs(I dont know why). I need the WM_SIZING message to know what end is being drawn out, so I can resize my TreeView controls appropriately. Help.
