I frequently come across Windows programs that bundle in MSVCRT (or their more current equivalents) with the program executables. On a typical PC, I would find many copies of the same .DLL's. My understanding is that MSVCRT is the C runtime library, somewhat analogous to glibc/libc.so under *nix. Why do Windows programs have to bri...
I've been trying desperately to get my application (15 C# dlls and 1 C++/CLI dll with C++ Runtime DLL dependencies) to deploy with ClickOnce. I got it to work by just copying the Release folder, but ClickOnce refuses to copy the files (msvcm80.dll, msvcp80.dll and msvcr80.dll) and deploy them in this folder. I did this nutty workaround ...
Do any one know why an application that always ran on Windows XP now suddenly crashes the msvcrt.dll? There were only minor changes made to the threading classes, which was done under Vista in VC++ 6. For all our libraries to work we are Dynamically linking to the MFC dlls. A newer version of msvcrt does not solve the problem. Any i...
We have an app compiled using MSVC 2K5, SP1 (version 762 msvcrt80) All is well, right up until somebody installs on the same machine .Net3.0SP1, and along with it msvcrt80 version 1433 is installed and a policy to automatically upgrade. Now we have random crashes all over the place and unhappy customers. I understand we can adjust our...
Hi, I'm trying to use the CRT memory leak detection but I keep getting the following message in Microsoft Visual Studio: "Detected memory leaks - skipping object dump." I can never get the it to actually do and object dump. I followed the directions in the Microsoft article on Memory Leak Detection (http://msdn.microsoft.com/en-us/libra...
Can zlib be used with masm without all the c runtime libraries such as msvcrt.dll and many others? If so, can you tell me how? ...
Recently upgrade a MFC++ Project which includes .NET assemblies from Visual Studio 2005 to 2008. Now whenever its installed it displays the following message: The procedure entry point _wsplitpath _s could not be locating in the dynamic link library msvcrt.dll I've install Microsoft Visual C++ 2008 SP1 Redistributable Package (x8...
Windows HeapFree, msvcrt free: do they cause the memory being freed to be paged-in? I am trying to estimate if not freeing memory at exit would speed up application shutdown significantly. NOTE: This is a very specific technical question. It's not about whether applications should or should not call free at exit. ...
I don't know if it's possible to do this, but I would like the /NODEFAULTLIB to be applied to a static library project. I have many application projects (A.exe, B.dll, C.dll) that use a common static library D.lib. This library has a lot of code and also has other .lib dependencies as well. One of them is the openssl library, which seem...
I am reading Microsoft's CRT source code, and I can come up with the following code, where the function __initstdio1 will be executed before main() routine. The question is, how to execute some code before entering the main() routine in VC (not VC++ code)? #include <stdio.h> #pragma section(".CRT$XIC",long,read) int __cdecl __initstd...
I am using VS2008 for developing a COM dll which by default uses CRT version 9 but I am using TSF (Text service framework) that is not compatible with the new CRT. I think the solution is to use the compatible one so how can I specify the CRT version? ...
In Visual Studio, there's the compile flags /MD and /MT which let you choose which kind of C runtime library you want. I understand the difference in implementation, but I'm still not sure which one to use. What are the pros/cons? One advantage to /MD that I've heard, is that this allows someone to update the runtime, (like maybe patch...
What happens when you call WaitForSingleObject() on a handle you've created with CreateFile() or _get_osfhandle()? For reasons not worth explaining I would like to use WaitForSingleObject() to wait on a HANDLE that i've created with _get_osfhandle(fd), where fd comes from a regular call to _open(). Is this possible? I have tried it in ...
I have read arguments on both sides about whether one should link to the C runtime library statically or dynamically in Visual Studio projects, and I'm still not entirely sure what to think. My project pulls in some third-party libraries (Python, HDF5, Trilinos, and Microsoft MPI), each of which has to be built with the same runtime lib...
I'm porting some C++ code from UNIX to Windows which detects the occurrence of the EDQUOT error, which indicates that there was an unsuccessful attempt to exceed the current user's disk quota. Visual Studio's <errno.h> doesn't have an EDQUOT, although I know that Windows has disk quota functionality. Visual Studio's <errno.h> does have a...
A C++ program that uses several DLLs and QT should be equipped with a malloc replacement (like tcmalloc) for performance problems that can be verified to be caused by Windows malloc. With linux, there is no problem, but with windows, there are several approaches, and I find none of them appealing: 1. Put new malloc in lib and make sure ...
To minimize deployment package, I'd like to know the CRT versions which are already included in .NET redists. The info I've already gathered are: .NET 2.0 -> CRT 8.0.50727.42 .NET 2.0 SP1 -> CRT 8.0.50727.762 However, I cannot find the CRT versions for .NET 3.5. I roughly remember I used to come across a blog page list all the version...
I am using ASSERTE macro to check for pre-conditions. According to its definition it is using ASSERT_BASE, which in turn calls _CrtDbgReportW to print out the message. Where does _CrtDbgReportW output goes to? I would assume that if the application is started from debugger, it would go to debugger window. Where would the messages go if ...
Observe this close Scenario even though it appears to be the same as my previous questions. Still I am not getting an answer. So please don't report as a duplicate. I have a project which has 10 dependencies. First I compiled using the /MTD option in the C/C++ codegeneration section in the main project and all its dependencies are getti...
