Creating a dialog inside a Dll??

[Heinz Grandjean]

Hello PB-Community!

CASE %DLL_PROCESS_ATTACH
gl_hInstance = hInstance

g_hMsgWnd = CreateDialog (gl_hInstance, BYVAL 100&, 0, _
CODEPTR(MyProc))
-----------------------------------------
CASE %DLL_PROCESS_DETACH
IF IsWIndow (g_hMsgWnd) THEN
DestroyWindow g_hMsgWnd
END IF

I use this modeless (hidden) (ressource-file) dialog as an asychronic message window (But this is not the topic of my question).

The Question: Am I allowed to create such a window in a DLL?
Are there maybe hidden problems (I know they always are?).
Testing seems to be ok? But....

Thanks for any comments.

Greetings,

Cannot (should not!) do this on the DLL_PROCESS_ATTACH notification. Check your API reference under DLLMain()

But as far as putting a function to create that window in the DLL, that's no problem at all. Once the DLL is successfully loaded, any procedure in that DLL may as well be in an #INCLUDE file in your "main" program.

(I do this a lot).

Creating windows in a Dll is how visual custom controls are made.
