This may be a short & simple question, but I've never found a satisfying answer to it: What code does the main() function usually consist of in a large C++ project? Would it be an incorrect assumption to think that it is usually just initializing a (wrapping) class object and calling a function inside of it to set things off? Why is ma...
I'm a newbie to C++. I'm trying to have a char pointer as an out parameter for a function. But the changes made in the function are not reflected in the main function. What am I doing wrong? void SetName( char *pszStr ) { char* pTemp = new char[10]; strcpy(pTemp,"Mark"); pszStr = pTemp; } int _tmain(int argc, _TCHAR* argv[]...

Ive got some in memory images in various simple formats, which I need to quickly convert to another format. In cases where the target format contains an alpha channel but the source does not, alpha should be taken as its full value (eg 0xFF for an 8bit target alpha channel). I need to be able to deal with various formats, such as A8R8G8...

I have lots of (hierachical) data that I show in a TreeView (could be around 20K items or more, including children items). The peculiar problem with my data is that each object shown in the treeview can exist in many treeview items. What I mean by that is that I might have an hierarchy like this one: Item_A -> Item_B -> ItemC Item_B ->...
I have a weird problem when running an application that uses GNOME's libxml2 under Visual Studio 2008 (VS2008-SP1) and Windows XP. I have two C++ projects: Project A (a library) Project B (an application that depends on Project A) Both under one VS solution. Project A is statically compiled with libxml2.lib.

Hello. I've scoured the internet and my own intellect to answer this basic question, however, much to my own dismay I've been unable to find a solution.

I been working on a space sim for sometime now. At first I was using my own 3d engine with software rasterizer. But I gave up when the time for implementing textures was due. Now I started again after sometime and now I'm using Opengl (with SDL) instead to render the 3d models. But now I hit another brick wall. I can't figure out how ...

I recently switched from Bloodshed to Code::Blocks. I wrote a simple input/output program to get a feel for it, and when I tried to compile it I got errors for all of the headers I had included, saying that there was no such directory. I took a look at the file and saw that the file was saved as a C file rather than a C++ file, how do I...
I am working with a Wikipedia XML dump that is encoded in UTF-8. Right now, I am reading in everything as std::string, so when I std::cout to the screen, foreign characters are displayed as jibberish.
