I posted about a week ago, but only got one reply, which unfortuneatly didn't
help, so I'm reposting the problem, now summed up. (I apologize for the repost,
fixing this problem is somewhat urgent though)

 Executing: C:\PROGRAMMING\CONTEXT\ConExec.exe "C:\Programming\dm\bin\Sc.exe"
"C:\Programming\WinDBMst\windbmst.cpp" -oC:\Programming\WinDBMst\windbmst.exe
-mn -WA windbmst.def


DialogBox(hInst,MAKEINTRESOURCE(IDD_ABOUT), hwndMain,AboutDlg);
^
C:\Programming\WinDBMst\windbmst.cpp(204) : Error: need explicit cast for
function parameter 4 to get
from: int (*std func)(void *,unsigned ,unsigned ,long )
to  : int (*__import std func)()

When AboutDlg is cast as DLGPROC, the error isn't generated, but neither will
the dialogbox command function properly. Under other compilers the same bit of
code works, but not under DMC, however, it's DMC I wish to use.

What is the syntax in DMC for passing a dialog procedure to DialogBox, paremeter
4?

Hi,

I'm not quite sure what is going wrong, but I have a program that does:

if (DialogBox(hInst, MAKEINTRESOURCE(IDD_ADJUST), hwnd,
(DLGPROC)AdjustProc) == IDOK)

AdjustProc having this sig
proto:
 BOOL CALLBACK AdjustProc       (HWND hDlg, UINT iMsg, WPARAM wParam,
LPARAM lParam);

and start of function:
BOOL CALLBACK AdjustProc (HWND hDlg, UINT iMsg, WPARAM wParam, LPARAM)

Compiled as MCBS or Unicode Win NT exe and it is not using MFC. Works fine.

The cast to DLGPROC is required, but you have to make sure the function sig
matches the docs.

Thank you, knowing at least that DLGPROC casting is definately required helps
quite a bit, for a while I was using the lcc-win32 compiler, but it's lack of
c++ support got in the way. I switched to DMC almost without error, but
unfortuneatly some function calls aren't recognized (CreateFont,
CreateStatusWindow, DeleteObject) I figure I'm not including the write header
files(currently using windows.h, windowsx.h, and commctrl.h. If you have any
further information as to this, it would be much appreciated.
