Yes any dialog or window can be created from templates. The window one usually catches even seasoned programmers out. If you look at the template call CreateDialogIndirectParam the DLGPROC is optional. What you do is pass in the window handler and use setwindowlong to put it onto the modeless dialog which just happens to have all the style flags of a window. Once it has the handler attached you can just insert it into any APP window or even the desktop because it's a normal window and so you fake CreateDialogIndirectParam returning a fail. Did you notice it's up to you to call DestroyWindow and that is why they don't do it automatically. Sometimes it's useful to lie to the API Smile | :)

Yes its a template you can launch multiple copies as it only gets read and all global alloc memory is thread safe. It can't write or move anything as you usually only allocate just enough space to hold the resource. I assume that all still holds true for MFC. Officially the GlobalAlloc etc is now "old" but they have not got around to giving us replacement template system.

Most windows programmers are familiar with LoadResource and loading bitmap/icons/menus etc because they are going to draw them on screen alot but using the system for dialogs and windows usually escapes them because they don't need the response of a window like in your example.
In vino veritas
