C ++/CLI与VB和VC ++一起使用 [英] C++/CLI being used with VB and VC++
问题描述
我已经在这里发了好几次贴子，除了很好的建议外，什么也没有得到，所以我又一次带着最近的C ++/CLI头痛回去.在C ++/CLI库中，结果是MyLib.dll.我已经在C#上很好地工作了，但是想在VC ++和VB中生成一些示例代码，而且似乎无法弄清楚如何使这两个代码正常工作.
我可以编译使用以下C#程序:
$ csc/nologo/platform:x86 TestProgram.cs/r:MyLib.dll
我对VB几乎一无所知，也不知道到底有什么不同在VC ++和常规C ++之间.我正在寻找的是有关说服VC ++程序和VB程序与MyLib.dll进行通讯的说明.我在互联网上发现的大多数内容看起来过时，或强制存在.lib文件.
长话短说，从VC ++调用C ++/CLI .dll中定义的函数需要采取什么步骤?和VB代码?
I''ve posted on here several times and gotten nothing but great advice, so I once again return with my most recent C++/CLI headache.
First, I have some native code, which I wrapped in a C++/CLI library, and the result was MyLib.dll. I''ve gotten this working very well with C#, but would like to produce some example code in VC++ and VB, and can''t seem to figure out how to get those two working.
I could compile the C# program using:
$ csc /nologo /platform:x86 TestProgram.cs /r:MyLib.dll
I know pretty much nothing about VB and don''t really know what''s different between VC++ and regular C++. What I''m looking for are instructions on what I need to do to convince a VC++ program and a VB program to talk to MyLib.dll. Much of what I found on the internet either looked dated, or mandated the presence of .lib files.
Long story short, what steps need to be taken to call functions defined in a C++/CLI .dll from VC++ and VB code? Any and all advice is very much appreciated!

MyLib.dll是混合模式DLL(使用/clr开关编译)，对吗?
与本机代码中的混合模式DLL进行通信非常困难.我想，您需要使用条件编译，并根据编译器选项公开托管和非托管客户端的接口. _MANAGED是将在使用/clr编译开关时定义的宏.利用此宏来决定需要向本机客户端公开的功能.您还需要为本机客户端提供一个头文件，因为它们无法从程序集元数据中读取.
我还没有尝试过上述方法，但是我相信它应该可以解决问题.

MyLib.dll is a mixed mode DLL (compiled using /clr switch), right?
Communicating with a mixed mode DLL from native code is tough. I guess, you need to use conditional compilation and expose the interfaces for managed and unmanaged clients depending upon the compiler options. _MANAGED is a macro which will be defined when /clr compilation switch is used. Make use of this macro to decide the functions you need to expose to native clients. You need to provide a header file as well for native clients as they can''t read from the assembly meta data.
I haven''t tried the above, but I believe it should do the trick.
