I'm seeing some different behavior between g++ and msvc around value initializing non-copyable objects. Consider a class that is non-copyable: class noncopyable_base { public: noncopyable_base() {} private: noncopyable_base(const noncopyable_base &); noncopyable_base &operator=(const noncopyable_base &); }; class noncopya...
My application is an SDI with multiple views. By default, it creates a new document when the application starts. I want to modify this behavior so that a new document is created only when user explicitly clicks on "New". Or at least mimic this behavior. Any ideas? I am using Visual Studio 2008 with MFC feature pack. I googled and found s...
I recently wrote an implementation of the Canonical Huffman compression algorithm. I have a 500kb test file that can be compressed to about 250kb when running the debug and release builds from within Visual Studio 2008. However when I run the release build straight from the executeable the test file only compresses to about 330kb. I am ...
I have an application that contains a VC++ project (along with C# projects). Previously, (i.e. during the last year or so) when a build has been done, Visual Studio 2005 appears to be targeting the VC++ runtime version 8.0.50727.762. At least, that is what the Assembly.dll.intermediate.manifest file is telling me: <?xml version='1.0' en...
Hi All, I'm trying to use windows' API IsTextUnicode to check if a character input is unicode or not, but is sort of buggy. I figured, it might be better using a regex. However, I'm new to constructing regular expressions. What would be the regex to check if a character is unicode or not? Thanks... ...

In this maximally clipped source example, the manifest constant FOOBAR is being redefined. This is deliberate, and there is extra code in the live case to make use of each definition. The pragma was added to get rid of a warning message, but then a note appeared, and I don't seem to find a way to get rid of the note. I've been able to ...

I've just started with C++, and maybe there's something that I'm doing wrong here, but I'm at a loss. When I try to build the solution, I get 4 LNK2005 errors like this one: error LNK2005: "public: double __thiscall Point::GetX(void)const " (?GetX@Point@@QBENXZ) already defined in CppSandbox.obj (there's one for each get/set method, an...
This is a fairly basic question, but I haven't been able to find any from->to guides from VS6->VS2008. I have a dialog box that contains controls of various types, I've discovered the way of auto-generating OnBnClickedMyFooBarButtonHere() methods via the Properties dialog on the dialog editor. I can also use CWnd::GetDlgItemText(int ,CS...

Recently I came across some strange behaviour of my application. It has been developed mainly in C# but CLI/C++ was also used to achieve better performance. I was getting a System.NullReferenceException in a very simple method at the TimeSpan comparison: TimeSpan _timestamp; void UpdateFrame(TimeSpan timestamp) { if(TimeSpan::Equals...
I want to add icon file to my Win32 project, how to do that in VC++ Express? I created *.res file with XN Resource Editor, but I don't know what to do with it. Guess I need resource script, *.rc? What to write in that script ( probably must link *.res file that I created ). So I have *.res file, need *.rc script (don't know what to write...

So I tried moving my project to Visual C++ Express 2010 on Windows 7 from a previous version on Windows XP. I got all sorts of errors where atlbase.h was not found. This isn't so much a question but I wanted to document what my resolution was for others. Copied the following PlatformSDK files from my previous install and put them on m...

I've made a custom control, and when I want it to repaint on the screen I call Invalidate(), and afterwards UpdateWindow(), but i get message: debug assertion failed for a file afxwin2.inl in line 150 which is: AFXWIN_INLINE void CWnd::Invalidate(BOOL bErase) { ASSERT(::IsWindow(m_hWnd)); ::InvalidateRect(m_hWnd, NULL, bErase); } ...
I have a legacy C++ application with a deep graph of #includes. Changes to any header file often cause recompiles of seemingly unrelated source files. The application is built using a Visual Studio 2005 solution (sln) file. Can MSBUILD be invoked in a way that it reports which dependency(ies) are causing a source file to be recompiled...
I recently installed Visual Studio 2010 Professional RC to try it out and test the few C++0x features that are implemented in VC++ 2010. I instantiated a std::vector of std::unique_ptr, without any problems. However, when I try to populate it by passing temporaries to push_back, the compiler complains that the copy constructor of unique...
Good day, I am learning Testing in Visual Studio C++ and I have several tutorials which I have followed. I am trying to load a test fixture. I have tried to put the test .cpp file in many different places but it will still not pick up on it when I click on "Run Tests" or "Run Tests without debugging" In the tutorials I found, they seeme...
