I've been struggling with C++ source primarily intended for MS VCPP 7 and other versions, and notice that some sections are conditionally compiled based upon the number that _MSC_VER has been set to. Some DMC programmers seem to go around and on a case by case basis and adding an || defined(__DMC__) to the #if. Is there a MSC version number that would be pretty much catch most things rather than currently defaulting to having the source flow path act as if DMC can't handle anything that MSC can? e.g. #if !defined(WINAPI) #if defined(_WIN32) && (_MSC_VER >= 800) #define WINAPI __stdcall #elif defined(WIN16) #define WINAPI _far _pascal #else #define WINAPI _far _pascal #endif #endif I presume DMC happily handles __stdcall so if WINAPI is not *yet* defined but _WIN32 is, if I read that cluster of defines correctly, it will result in the last define being processed and the macro WINAPI equates to _far_pascal which I believe would be wrong for DMC... I understand that one can add in each and every similar situation an additional clause could be added || defined(__DMC__) but that could amount to hundreds of edits or more when maybe simply pre-defining _MSC_VER 1000 or some other number would reduce the initial screen loads of warnings and errors? Leaving just those truly MS only CPP quirks that have to be coded around conditionally? It is just seeming like too much battling compiler conditionals that have no relevance to porting between different compilers but to backwards compatibility... I am not an accomplished CPP programmer and have a couple of projects I need to attempt but so far I've yet to find a relevant tutorial or library and compiler that will work enough for me to take the initial steps needed to find out how to do the things I need to do with COM classes and the general win32api. I have installed on another machine that runs XP SP2 the MSVCPP 2005 express commandline compiler and the current PlatfomSDK from the ISO distro' download and even that would not compile all the included samples with the MS VCPP compiler when I followed the instructions word for word! There seems to be no download, install and start learning to program... instead its download, install and start learning to workaround compiler dialects and other incompatibilities. TIA
