Hello A) (Int32)X | ((Int32)Y << 16); B) (Int32)X + (Int32)Y * (Int32)Int16.MaxValue; Shouldn't both be equivalent? I know from testing that the first works as expected, but for some reason the second doesn't. Both X and Y are shorts (Int16), and the return type is an integer (Int32). Shouldn't Y << 16 <=> Y * Int16.MaxValue? ...

EDIT: I tried Keegan Hernandez's idea but I think I mi...

Hello. I'm trying to send a key stroke to one application, through PostMessage. I am using too Spy++ to try to understand how to send the message, as I do not fully understand its inner workings.

I am having a problem placing an instance of my reference-counting Pointer<Type> class into my Array class. Using the debugger, it seems that the constructor is never called (which messes up the reference-count and causes a segfault down the line)! My push_back function is: void push_back(const T& element) { if (length >= max) reall...

Hi Guys, What is the compatible "int" datatype in C++ that can resize itself to 4 bytes on 32bit & 8 bytes on 64bit windows? Although INT_PTR works fine but it reduces the readability as well as its description tells us to use it for pointer arithmetic. Thanks ...
