“APIENTRY _tWinMain” and “WINAPI WinMain” difference
What functions does _WinMainCRTStartup perform?
I just started to dive into windows programming. And when I tried to understand the win 32 program I noticed that the program has two entry points which are _tmainCRTStartup and _WinMainCRTStartup. Besides, I found the _tmainCRTStartup function also called _WinMain function. I just wonder what are they used for? And why there are two different entry points.
Thanks!

Changing a macro at runtime in C

Right now I'm merging two codes with the same core, but they differentiate with the #defines, what I need is to make a way around it an choose wicth configuration I need on run time, the code uses if ENABLE(defined) to verify the configurations to load, how can I modify the code to make it work?
Thanks
You can't. Macro are pre-processor. They are gone during compilation.
Variables are the best choice.

C++ cache aware programming

I am profiling my code on various CPUs running Windows7 and my results so far suggest that I need to tune a buffer size proportional to the machine's L2CacheSize or L3CacheSize. Is there a way to obtain these parameters from C++?
You can use the GetLogicalProcessorInformation function to get that. It returns an array of SYSTEM_LOGICAL_PROCESSOR_INFORMATION structures which contain a CACHE_DESCRIPTOR structure, which provides the cache size information.

Is there a library that can be implemented relatively easily in windows?
I made a few functions a while ago which used arrays of numbers to get the desired outcome. I might work at them when I get the time.
But is there any such feature already available that can be implemented into c++ easily?
Apparently people have had luck with using the GNU Multiple Precision Arithmetic Library for Windows.

Are there any cross platform crash reporters for C++ besides google-break pad? I have seen google-breakpad but it has very very limited documentation, and I have nothing seen very much mentioned here, google or other source websites
Have a look at BugTrap which might help you.

Calling functions from main() in c++
Hello.
I have a programme that has about 100 classes and more than 1000 functions spread over 20 header and source code files. What I want to know is that how I can pass arguments to so many functions in so many files? What is the procedure adopted for this in main()?

Take a look at the Boost.Program_options module.
