I've got an x86 Visual Studio solution with many project files in it. Some of the DLLs are designed to work as plug-ins to other applications on a user's system. We're expanding some of the DLLs to be able to support 64-bit applications. What I'd like to do is setup the solution/projects so that just hitting "Build" will build both th...
Simple question, I'm writting a program that needs to open huge image files (8kx8k) but I'm a little bit confused on how to initialize the huge arrays to hold the images in c++. I been trying something like this: long long SIZE = 8092*8092; ///8096*8096 double* array; array = (double*) malloc(sizeof(double) * SIZE); if (array == NU...
When I remotely "Attach to Process" in Visual Studio 2008 SP1 to WS2008 (x64) computer running remote debugging monitor (both RTM and SP1), I see a huge number (30+) of entries saying: <username> connected Both TCP and authenticated mode are affected. I think there is an entry per unique process name. Each connection attempt takes se...
Hello. I recently installed W7 pro 64bits on my laptop, and then VS2008 pro with x64 compatibility. If i build any project, will it be built with 32 or 64 bit compatibility natively? And then, is it possible to change from 32 to 64 (or from 64 to 32) ? 'Cause most of my clients only runs 32bits applications, but I'd also liked to kno...

I have a strongly recursive function, that creates a (very small) std::multimap locally for each function instance using new (which recurses to malloc/calloc in the std lib).

Sigh, I have some code from codeproject (http://www.codeproject.com/KB/cs/globalhook.aspx) for hooking global keyboard and mouse events. Suddenly now when I installed beta 2 of visual studio 2010 and .net framework 4.0 i breaks at this code: hKeyboardHook = SetWindowsHookEx( WH_KEYBOARD_LL, K...
I have a windows web 2008 x64 installation running. Due to the requirement for the application having the ability to import Excel files, I have had to change the web application to run in 32bit mode.

I've been trying to improve the build times for my product. We're using continuous integration, and our builds are now taking 2 hours to run. I've looked at the NANT timings and see alot of places that are slower than they should be, but one that jumps out is the x64 builds of our Visual C++ projects. Here's an example of the timings ...
I have a c# application that is compiled as x86 so it runs as a 32bit application on Windows 7 x64. While the application is running, I need to detect the executable name of the active window. On Winodws XP the following code worked fine (getting the process filename from the active window handle). On x64 it reports the name of only the ...

I am creating a wrapper around a native lib, which comes in both 32 & 64 bit flavors. I have a fairly complex C++/CLR project that includes a number of header files from the native libs. I got it to work fine on x32, but now I'm not sure how to provide an alternative x64 build. Can someone outline the steps to create such project? Var...
