Hi, I'm tring to migrate my code from VCpp 6 to VCpp 2008 express but when I build the solution I receive this error message: icl: warning: problem with Microsoft compilation of 'c:\Desenvolvimento\DFF\Base\\version.cpp' 1>C:\Arquivos de programas\Microsoft Visual Studio 9.0\VC\include\string.h(69): error: expected a ";" 1> __DEFINE...
C++0X Concepts are gone. Which other features should go too?
As you may have heard, the last meeting of the C++ standards committee voted to remove concepts from the next C++ standard. Of course, this will affect other features and would seem to throw the standard wide open again. If that is the case, which other features do you think should be stripped away (or added), and why? Links: Removal o...
where do you define typedef for complex maps?
General question: Where is usually defined class, namespace. My case: I am only using this maps in my class implementation: std::map<const std::pair<string, string>,const string*> and I wonder where is it good place to put it in the class (in public:) or in the enclosing header file? I don't have namespaces ...
Alternatives to LogonUser for network impersonation (C++)
Are there any alternatives to LogonUser and for impersonating given account in order to access network resources? I'm looking for the method of impersonation which would let me connect to machine in foreign domains (or, workgroup machines for the same matter). For initial data I have: machine name, username (or domain\username), cleart...

std::vector resize downward
the C++ standard seems to make no statement regarding side-effects on capacity by either resize(n), with n < size(), or clear(). It does make a statement about amortized cost of push_back and pop_back - O(1) I can envision an implementation that does the usual sort of capacity changes ala CLRS Algorithms (eg double when enlarging, ha...
Assignment question in c++
Hello. Coming from c#, where classes instances are passed by reference(this is, a copy of the reference is passed when you call a function, instead of the integral value), I'd like to know how this works in c++. In the following case, _poly = poly; is copying the value of poly to _poly, or what? Thanks #include <iostream> #include <stdi...
How to add submenu to a CMenu in MFC?
I have an MFC app that uses CMenu for the main menu bar. I haven't been able to create submenus successfully.

Must every test-case undo their operation at the end?
Hi, The question may be a little vague but here's an example of what I want to know (pseudocode): //start test-case for CreateObject function { // initialization of parameters MyObject *obj = CreateObject(); // test results } //end test-case for CreateObject function Is it necessary in this case to also deallocate the memory by calli...
C++ Newbie question: ThreadProc
Hi I am just trying to understand some source code written in C++. I am a bit familiar with C++, however, the following code sequence is absolutley new to me. A guess would be that here I register some thread routine with the kernel, ptest->Run(). Could that be right? static unsigned int __stdcall ThreadProc(void *lParameter) { CTe...
Function Call Guard
Suppose I have a free function called InitFoo. I'd like to protect this function from being called multiple times by accident. Without much thought I wrote the following: void InitFoo() { { static bool flag = false; if(flag) return; flag = true; } //Actual code goes here. } This looks like a big wa...

I'd like to use the C99 header file inttypes.h in a Visual Studio project (I'd like to printf 64 bit numbers). However, this file does not seem to exist in my install. Is this just not part of VS2005? Are there any alternatives? ...
Overcoming bad habit of "fixing it later"
When I start writing code from scratch, I have a bad habit of quickly writing everything in one function, the whole time thinking "I'll make it more modular later". Then when later comes along, I have a working product and any attempts to fix it would mean creating functions and having to figure out what I need to pass. It gets worst b...
