使 DLL COM 可访问 [英] Making a DLL COM accessible

问题描述

我有一个用 .Net 编写的类库，我想将它提供给 VB6/VBA.我试过的没有用(显然我在问这个问题).这是我所做的:

1. 我在 Visual Studio 2010 Express 中创建了一个类库项目并将代码放入一个类模块中.
2. 我打开项目属性并转到程序集信息"并选中使 COM 可见".
3. 我转到高级编译"选项并针对 .Net 2.0(这是非常简单的代码).
4. 然后我删除了所有对系统"的引用.
5. 我构建了项目(没有警告或错误)并将 DLL 从 Bin 文件夹复制到 C:WindowsSystem32
6. 我运行 RegSvr32 注册 DLL 并得到错误:

<块引用>

模块MyDll.dll"已加载，但未找到入口点 DLLRegisterServer.

确保MyDll.dll 是有效的 DLL 或 OCX 文件，然后重试.

显然我的第一次尝试有点天真.有人可以提供指导吗?

解决方案

第 6 步错误.具有 [ComVisible] 类型的 .NET 程序集在 Regasm.exe 中注册.如果您不想将 DLL 安装到 GAC 中，请使用/codebase 命令行选项./tlb 命令行选项创建类型库，您可以在 VB6 项目中使用它.

I have a class library written in .Net that I would like to make available to VB6/VBA. What I tried did not work (obviously as I am asking this question). Here is what I did:

1. I Created a Class Library Project in Visual Studio 2010 Express and put the code in a Class Module.
2. I opened the project properties and went to "Assembly Information" and checked "Make COM Visible".
3. I went to "Advanced Compile" options and targeted .Net 2.0 (it's very simple code).
4. I then removed all references expect for "System".
5. I built the project (no warnings or errors) and copied the DLL out of the Bin folder into C:WindowsSystem32
6. I ran RegSvr32 to register the DLL and got the error:

The module "MyDll.dll" was loaded but the entry-point DLLRegisterServer was not found.

Make sure that "MyDll.dll is a valid DLL or OCX file and then try again.

Clearly my first attempt was a bit naive. Could someone offer guidance?

解决方案

Step #6 is wrong. .NET assemblies with [ComVisible] types are registered with Regasm.exe. Use the /codebase command line option if you don't want to install the DLL into the GAC. The /tlb command line option creates the type library, you can use that in your VB6 project.
