In a derived class I have a function called evaluate() (it's a virtual in the base class). In this derived class i also have a function set_value() and hence i want get_value() as well. get_value() should return the exact same thing as evaluate() Is there anyway to say that a call to get_value is a call to evaluate()? With some sort of ...

Hi I am trying to find the most efficient, optimized and fastest way to compare to std vectors of CString. the strings in question are case-sensitive. I have tried using the == operator for the vector container but this sometimes return false positives. I mean for instance if one vector contains elements in the order (a,b,c) and the oth...
If the following from the C++ FAQ Lite is true: "a function name decays to a pointer to the function" (as an array name decays to a pointer to its first element); why do we have to include the ampersand? typedef int (Fred::*FredMemFn)(char x, float y); FredMemFn p = &Fred::f; And not just: typedef int (Fred::*FredMemFn)(char x, flo...
My application compiles with VC6 sp6, uses DBGHelp.lib to get stack information. The code is simmilar in debug and release compilations. The problem is that when executing the debug version, DBGHelp.dll loads msvcrt.dll (the release version). msvcrtd.dll is already loaded by my debug link anyway. So I end up having both msvcrtd.dll and m...

Hello, I'm trying to use libcurl with a program I'm making, but I'm having some problems with it. So far I've only tried the examples from libcurl's website, but they crash as soon as the program gets to the curl initialization.

I have a big project with a bunch of .cc files that have mostly c code and some c++ code. I want to use a vector in this program since I need an unbounded data type that is simple to make 2d (in other words I don't want to use an array or a list). The problem is that when I run my make after including the vector class I get errors that I...
