c++ - Background color problem

reply "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:
