Macro and Member Function Conflict

macro and member function conflict

The workaround is to use the parenthesis: int max = (std::numeric_limits<int>::max)();

It allows you to include the windef.h, doesn't require you to #undef max (which may have adverse side effects) and there is no need to #define NOMINMAX. Works like a charm!

How to properly solve macro conflict (GetMessage) between Windows API and DirectX API & other APIs developed by microsoft

nothing need do here and no any conflict or problems in your code. you already viewed this yourself

it compiled successfully and these methods can still be called
normally runtime

and you correct - methods called not by name but by address in virtual table. the winuser.h always included before IDXGIInfoQueue declaration, so already inside interface declaration GetMessage expanded to GetMessageW or GetMessageA. the same in your code, which call method on interface ( DXGIInfoQueue->GetMessage). as result names coincide.

But still, it just feels wrong using the wrong names...

here you have wrong feels. again - all is ok and nothing need todo

How to define a macro using other macros, when those other macros raise name conflicts

Compiling comments to make an answer:

Solution A,

if you for some reason have to stick with "ROW" and "COL" in your code (credits to melpomene):

enum { ROW = 100 }; 
enum { COL = 200 }; 
enum { ARRSIZE = ROW*COL };

Solution B,

if you are free to choose identifiers; more robust for future reuse:

Avoid the naming conflict by choosing different, non-conflicting, longer identfiers.

I have a superstitious distrust of short, obvious identifiers, the conflict you encountered is a good example why. Other examples have cost my employers quite some time and money.

(I have seen melpomene elsewhere not being interested in the reputation for an answer anymore, very altruistical. I think it is worth making a nice Q/A pair here and does not take anything from melpomene.)

VS2017 #error: : Macro definition of snprintf conflicts with Standard Library function declaration

As the error in your question shows, you have a macro definition for snprintf that is no longer compatible with your current version.

So you need to look for the following:

#define snprintf _snprintf

You can either remove it or if you need to also compile your code with Visual Studio 2010 you can add the following condition:

#if _MSC_VER < 1700 
#define snprintf _snprintf
#endif

how to avoid name conflicts coming from #define in C? (or C++)

You cannot work around this because that's the preprocessor goal: modifying your code on the fly. The solution is to adopt good coding practices: don't use the preprocessor for general programming. Also, use a naming discipline with namespaces. K what ? Name it CONVERSION_ID_K, CONVERSION_ID_L, and so on. Use lower case for variables, etc.
