Dialog Boxes WinApi

I''m trying to make a windowed level editor (d3d) but I''m having trouble getting a dialogbar I''ve created with the vc++ 6 resource editor to even show up. I''ve called DialogBox() and CreateDialog() but it''s not doing anything while a tutorial source code seems to work fine. I can''t find any differences between the sample and my code.

Thanks but sorry it didn''t work 
I also have the WS_VISIBLE set in my dialogbar resource so according to the articles I read, it should display automatically.

I''m not sure what your variable WindowTitle contains. However, that could explain your error if it is not the exact same as
the class name you listed when registering window:
wndclass.lpszClassName = "EuEnv Application";
Ensure that the second param in CreateWindowEx is the exact same as the one above.
And your right, the Visible tag removes the need for ShowWindow for the dialog. But, I did not see a ShowWindow(hWnd , SW_SHOW); for your main window? I pretty positive you need to call:
ShowWindow(hDialog , SW_SHOW);
UpdateWindow(hWnd);
after creation.
Thats all I can see from your source listing however.

WindowTitle holds "EuEnv Application" as well that CreateWindowEx () function was a cut and paste from one of my engine functions so that''s why it had WindowTitle instead (oops) sorry
And yup, I call ShowWindow and UpdateWindow afterwards.
This is the Dialog Bar part of the rc file:
If this still doesn''t make any sense, is there a better way of getting dialog input from the user?
Thanks for everything!

I'm no prob on the windows resource script. In fact, I had a similar problem before, which I have not found a solution for. But, I have little need for windows dialogs anyway. The problem I was having was that I couldn't use a richedit, or I would get an error in my dialog and it would not show. But I see you are only using the spin control , some static text, and some inputs... Hmm.. I see no problem there.
try changing the WS_CHILD to WS_POPUP or WS_OVERLAPPED.
As for as a better way to get input... Well, if your making a windows app (Such as an level/stats editor or something), win dialogs are the best way. But, if your making a game, I would suggest making a custom GUI control.
If your project is small (under a meg), I wouldn't mind taking a look at it if you zipped it up and sent me the wholle project directory.

Thanks! I''ve simplified everything to just the window and zipped it and emailed it to you. It''s about 8kb but same problem still so I dunno. It''s a really weird problem. I hope you can find out what''s wrong. Thank you so much again!

posting the whole simplified main.cpp here just in case as well...

Okay, this is weird... I just made a completely new dialog box and it worked. I'm not sure what it is about the last one that made it not work. I'll keep looking into it but hmm...
Edit: found it! It's the spin controls that are causing it to not work! ARGH...

Spin controls? I''m not familiar with those except that they exist in MFC. I would guess that a call to InitCommonControls[Ex]() would solve your problem.
