[GD-Windows] OT:DirectX Game Engine

[Weston F. <we...@ml...>]

<I hope this isn't too far off topic here, If it is please forgive me>

I'm looking for suggestion on which 3D Engine to use in my Game.. If you =
know of any that are decent ones that support DirectX (hoping for DX7 =
and above) please email me off list.

Thanks

[GD-Windows] CreateDialog failure

[Pierre T. <p.t...@wa...>]

Hi,

I create a dialog using something like :

handle =3D CreateDialog(
      hInstance,
      MAKEINTRESOURCE(IDD_DIALOG1),
      hWnd,
      NULL);

But returned handle is null, which means (I guess) something went wrong.

So I tried :

  DWORD Er =3D GetLastError();

Then retrieving the error string using FormatMessage (using the code =
snippet from the MSDN). But it doesn't help since error code is 0 and =
the translated string says there was no error.

Hmm. What do I do now ?
What are the usual reasons for CreateDialog to fail ?

In case it's important, the call takes place in a DLL dynamically loaded =
by a 3DS MAX plug-in, and hInstance and hWnd used to create the dialog =
are the ones from the MAX plug.

Are you really passing NULL as the DLGPROC, or was that an
oversight typing the email? I didn't think that was an
optional parameter.

I got bitten at some point by having some common controls
in a dialog, but forgetting to use InitCommonControls() or
...ControlsEx() which caused me no end of stress for being
something so blindingly simple %)

Other than that: beats me :)

Cheers,

Doesn't seem to make any difference. But it must be optional, I've already
successfully created dialogs that way in other apps.

I'm not using common controls, this is just the default created dialog with
OK / Cancel right now.

Hmmm.

Hrmpf. Guess that rules out those options, then.

From the original post:

But the dialog resource is actually in the plug-in, and not
in the dll? :-)

If yes, I wonder if there's any obscure rules as to acessing
another's hinstance - I wouldn't think so, but maybe someone
else knows more?

> Hmmm.
Yes, definately :)
