dll

问题 I'm using Visual Studio 2008 SP1 for C++. When compiling, Visual Studio needs to choose against which version of the CRT and MFC DLLs the application should be linked, version 9.0.21022.8 (= RTM), 9.0.30729.17 (= SP1) or 9.0.30729.4148 (= SP1 with security update). I'd like to know how you can choose which of both versions will be linked against. Does anyone know? Note : this is important when using a private assembly, because you need to know which versions of the VC 9.0 DLLs to copy along

问题 i'm wondering why linkers can not do their job simply by consulting the information in the actual .dll files that got the actual implementation code ? i mean why linkers still need .lib files to do implicit linking ? are not the export and relative address tables enough for such linking ? is there anyway by which one can do implicit linking using only the .dll without the .lib stub/proxy files ? i thought the windows executable loader would simply do LoadLibrary/LoadLibraryEx calls on behalf

问题 I have a DLL written in VB 6 and another DLL written in Visual Studio 2005 (VB.NET). Now I want to invoke the method of the VB DLL from my .NET DLL. What should I do for this? Any thoughts? 回答1: As VB6 creates COM DLLs, Visual Studio should have no problems generating an interop stub for you. Simply add a reference to the VB6 DLL from your .NET project by selecting Add Reference in Visual Studio and finding your DLL under the COM tab. Make sure the VB6 DLL is registered on your machine before

问题 We need to interface to 3rd party app, but company behind the app doesn't disclose message protocol and provides only Windows DLL to interface to. Our application is Linux-based so I cannot directly communicate with DLL. I couldn't find any existing solution so I'm considering writing socket-based bridge between Linux and Windows, however I'm sure it is not such a unique problem and somebody should have done it before. Are you aware of any solution that allows to call Windows DDL functions

问题 I want to make a simple, simple DLL which exports one or two functions, then try to call it from another program... Everywhere I've looked so far, is for complicated matters, different ways of linking things together, weird problems that I haven't even begun to realize exist yet... I just want to get started, by doing something like so: Make a DLL which exports some functions, like, int add2(int num){ return num + 2; } int mult(int num1, int num2){ int product; product = num1 * num2; return

问题 I want to have a single Visual Studio project that builds a DLL file and an import library (.lib) file. (An import library is a statically-linked library that takes care of loading that DLL file in other projects that use it). So I went to Visual Studio C++ 2008 Express Edition, created a New Project of type Class Library, and set the "Configuration Type" to be "Dyanamic Library (.dll)". But when I build the solution, the only relevant output file I see is a DLL file; I don't see any LIB file

问题 I have a question. I'm writing a plugin (.dll) for an application (.exe). And I want to code auto-update function for my plugin but I catched an issue, it could not apply. Because my plugin has loaded while application is running, in run-time it cannot replace. It just apply until application has exited. So, how can I do it? This is my code: http://codepad.org/4a22ccMa Thanks! 回答1: (this answers the original question, which has been edited to something completely different) It depends upon

问题 Im using undetermined DLLs which can use undetermined resources such as a COM port. Some DLL methods don't have their own timeouts, so i am forced to abort the execution thread. But if the thread is using a resource such as a COM port, and i abort the thread, my program crashes with the error “Safe handle has been closed”. I know why this happens but is there any way to catch this exception or skip it, rather than an actual crash? 回答1: Solution: Running the code in a separate AppDomain
