Hi,
I need help to compile our code using 64-bit compiler. Our software code has been compiled using Visual Studio Win32 compiler. But when I tried to compile using windows x64 compiler I get lot of errors. For example,

I get error that GCL_HBRBACKGROUND is undefined but it runs fine on windows 32 compiler. I might need to use GCLP_HBRBACKGROUND to compile correctly on x64 compiler.

So, my question is that is there any way that I can compile the same code or with using macros such as

#ifdef _Win64
#endif

on both Win32 and x64 compiler instead of having different copies of code, one for Win32 and one for x64.

Any help would be really appreciated.

Regards,
ABM
