Suppose I have this function:
std::string Func1(std::string myString)
{
//do some string processing
std::string newString = Func2(myString)
return
There is a much easier way in Visual Studio 2010/2012.
To accomplish what you are looking for in ANSI use this:
strcmp(newString._Bx._Ptr,"my value")==0
And in unicode (if newString were unicode) use this:
wcscmp(newString._Bx._Ptr, L"my value")==0
There are more things you can do than just a compare, you can read more about it here:
