问题 Hi guys I'm following this tutorial to build my first Java 3D application. I included in my project the java3D libraries and my DllLoader class that extracts (from the classpath to the jar's location) and loads the j3dcore-ogl.dll : public class DllLoader { private DllLoader() { } public static void extractAndLoad(String dll) throws IOException { int aux = dll.lastIndexOf('/'); if (aux == -1) { aux = dll.lastIndexOf('\\'); } File dllCopy = new File((aux == -1) ? dll : dll.substring(aux + 1));

问题 How can I find out the decorated name that will be asigned to each method name ? I'm trying to find out what the decorated name is , so that I may export it , in a DLL . 回答1: .DEF file are still being used? Forget .DEF files. They are a thing of the past. Export your functions, be them C functions or C++ symbols, through __declspec(dllimport/dllexport). If you really need undecorated names, use as suggested by Greg Hewgill, the __declspec(dllimport/dllexport) keywords, combined with extern "C

问题 I managed to set up build project in dll mode and in library mode but not together: for build in dll: project->properties->Configuration Type: Dynamic Library (.dll) project->properties->Target Extension: .dll for build in library: project->properties->Configuration Type: Static library (.lib) project->properties->Target Extension: .lib it is possible to build both of them together? 回答1: Yes, you can have single project that can be used for .dll and .lib. Steps to be followed: Visual Studio

问题 I have two applications in two solutions in VS2008 that share a common dll, the dll-code is included as a project in the first applications solution. Is it possible to allow the second solution to reference the dll project "readonly"? I want whoever opens the second solution to be able to step into the dll during debugging but not be able to change the code. 回答1: I would simply build against the dll+pdb. The pdb is enough to step into code, without ever being able to edit it. You can enable

问题 I'm attempting to port a simple C# command-line utility to Python. The C# program uses a custom .Net dll called foobar.dll that interfaces with some lab equipment via I2C. The usage of the dll in the C# code is as follows: fooBar.fooProvider provider = new foobar.fooProvider() fooBar.fooBarLib fooLib = new foobar.fooBarLib(provider, 0x80) # used below ... numFloat = fooLib.GetSomething() # more python ... fooLib.SetSomething(NumberAsAFloat) I thought about simply using ctypes to access the

问题 I have created one tool using console application named "DocumentHashcode" in which I am using third party DLL - DocumentFormat.OpenXml.dll . When I'm going to deploy it, I am using DocumentHashcode.exe and DocumentFormat.OpenXml.dll for running the application. I want to rename DocumentFormat.OpenXml.dll to CATBldHashCodeSupporterDll.dll . Can anyone advise how to achieve this? 回答1: You need to manually load the assembly. The simplest way is to load it before the JITer tries to load the

问题 I wish to use a COM dll in my C++ library. The way I figured going about it, is to #import the dll's .tlb file, which I did : #import "mycom.tlb" no_namespace The problem is , I don't quite know where to place this declaration. should it be inside the H file or the CPP file? or maybe the stdafx.h file? I tried placing it in the .cpp file , just for testing. in the H file I have this member declared : ILogicSecuredPtr m_pbLogic; (where ILogicSecured is the interface I want to work with in my
