Theres are couple of places in my code base where the same operation is repeated a very large number of times for a large data set. In some cases it's taking a considerable time to process these.
I believe that using SSE to implement these loops should improve their performance significantly, especially where many operations are carried...

double nVector[10000]; // for negative doubles

I'm encountering this error while compiling some old VC++ 6.0 source code.
error C2632: 'long' followed by 'long' is illegal
There's a part of the code that declares a long long int variable which caused the error. Does anybody know how I can fix this error compiling it in VC++ 6.0? I've searched around and I've read that this data ty...
I have a function which takes variable arguments, something like the following

Hi,
I have to check whether a function is being inlined by the compiler. Is there any way to do this without looking at assembly (which I don't read). I have no choice in figuring this out, so I would prefer if we could not discuss the wisdom of doing this. Thanks!

I am messing with a very big solution in Visual C++ 2008 (150+ projects), and by browsing the code with the useful "Go to Definition/Declaration" feature, I end up in C files, but I don't know in which project they belong ...
So here's my question : Is there a way to know the projects referencing a given file in a visual C++ solution ?

This MSDN document quotes:
look for include files in the same
directory of the file that contains
the #include statement, and then in
the directories of any files that

Wait, what?
What does that actually mean (the bold stuff)?

The CAdapt class is provided by Microsoft in order to enable using classes that override the address of operator (operator&) in STL containers. MSDN has this to say about the use of CAdapt:
Typically, you will use CAdapt when you want to store CComBSTR, CComPtr, CComQIPtr, or _com_ptr_t objects in an STL container such as a list.

Hi!
I've got a little problem. my application runs without problems in Debug mode, but crashes in release mode. I can't track down the problem, because in release mode all the Debuginfo appears to be nonsense. However - sometimes in other projects the Debug output is also valid in release mode. What projectsettings do I have to change s...
I'm currently looking at a function example that I can't seem to figure out using MFC in Visual C++. The function is as follows
CMFC_OSG_MDIView::CMFC_OSG_MDIView() :mOSG(0L)

}
I understand everything here except the mOSG(0L) snippet. mOSG was declared in the MFC_OSG _MDIView class as follows:
cOSG* mOSG;
Any help is greatly appr...
