What are the differences between parameter definitions as (type& name), and (type* name)?
A very basic question, but still, it would be good to hear from C++ gurus out there. There are two rather similar ways to declare by-reference parameters in C++. 1) Using "asterisk": void DoOne(std::wstring* iData); 2) Using "ampersand": void DoTwo(std::wstring& iData); What are implications of each method? Are there any gotcha's...

mem_fun_ref trouble
I am having trouble figuring out mem_fun_ref. I have to admit, I usually use functors for this kind of thing, since they can be inlined for speed and profit.

Cheating in online games: Is it possible to prevent one Win32 process from inspecting/manipulating another's memory?
I play the online game World of Warcraft, which is plagued by automated bots that inspect the game's allocated memory in order to read game/player/world state information, which is used to mechanically play the game. They also sometimes write directly to the game's memory itself but the more sophisticated ones don't, as far as I know. T...

The specified module could not be found - 64 bit dll
Hi Everyone, I had the 32 bit dll which is written using Native C, when I tried compiling with VC++(VS2008) for converting the dll to x64 by changing the platform it compiled. But when I tried to access the dll from my C# application which is also 'x64' platform it fails to load the dll. I used Dllimport for linking the dll with my appl...
How much memory was actually allocated from heap for an object?
I have a program that uses way too much memory for allocating numerous small objects on heap. So I would like to investigate into ways to optimize it. The program is compiled with Visual C++ 7.

Is there a less verbose way to achieve the same effect?...
WIN32 memory issue (differences between debug/release).
I'm currently working on a legacy app (win32, Visual C++ 2005) that allocates memory using LocalAlloc (in a supplied library I can't change). The app keeps very large state in fixed memory (created at the start with multiple calls to LocalAlloc( LPTR, size)). I notice that in release mode I run out of memory at about 1.8gb but in debug i...
