c++ - Background color problem

↑ ↓ ← → "Gary" <gedumer bcpl.net> writes:
I'm having a problem with the background color of STATIC, GROUPBOX,
CHECKBOX, and RADIOBUTTON controls using the DMC v8.32. Possibly other
controls as well, but these are the only ones I've tried. When I compile the
program with the Borland C/C++ 5.5 commandline compiler, all controls show
the same background as the main window, as set in the WNDCLASSEX structure.
Using the LCCWin32 C compiler, I have the same results. But with the DMC
compiler, these controls always have a white background, no matter what I
do. I also had the same problen with the OpenWatcom 1.0 compiler, but that
problem was solved by adding a "system win95" directive to the linker
command line. Is there a similar option for DMC? I'm using "dmc -mn win.cpp
gdi32.lib" to compile the program and a win.def file containing "EXETYPE NT"
and "SUBSYSTEM WINDOWS". I must be missing something. Also, I can't keep the
console window from showing. The test program follows:

                               40,
                               hwnd,
                               NULL,
                               g_hInst,
                               NULL);
         SendMessage(hCntrl,STM_SETIMAGE,IMAGE_ICON,(LPARAM)LoadImage(0,

 IDI_APPLICATION,

 IMAGE_ICON,

 0,0,LR_SHARED));
         return 0;
     case WM_DESTROY:
         PostQuitMessage(0);
         return 0;
     default:
         return DefWindowProc(hwnd,Message,wParam,lParam);
     }
 }

 Any ideas?

 I think you have to add
 EXETYPE           NT
 SUBSYSTEM     WINDOWS,4.0
 to the .def file.
