如何正确注册 VB.NET COM+ 组件的类型库? [英] How do I properly register the Type Library of A VB.NET COM+ Component?

问题描述

我希望将旧的 VB6 COM+ 组件升级到 VB.NET 组件.我似乎已经升级了一个叫做 EventPackage，它有一个类，IEventListener.另一个，TradeOrders，Implements EventPackage.IEventListener.尝试构建 TradeOrders 时，我收到以下错误/警告；

I am looking to upgrade legacy VB6 COM+ components to VB.NET components. I have seemingly upgraded one already, called EventPackage, which has one class, IEventListener. Another, TradeOrders, Implements EventPackage.IEventListener. When attempting to build TradeOrders, I get the following Errors/Warnings;

1. 无法加载引用EventPackage"的类型库.图书馆未注册.(来自 HRESULT 的异常:0x8002801D (TYPE_E_LIBNOTREGISTERED))
2. 找不到引用的组件EventPackage".
3. 未定义类型EventPackage.IEventListener".

在 .vbproj 中，我注意到这个引用

In the .vbproj, I notice this reference

<COMReference Include="EventPackage">
  <Guid>{0D76C094-21A6-4E04-802B-6E539F7102D7}</Guid>
  <Lcid>0</Lcid>
  <VersionMajor>2</VersionMajor>
  <VersionMinor>0</VersionMinor>
  <WrapperTool>tlbimp</WrapperTool>
</COMReference>

当我在注册表中搜索此 Guid 时，我什么也没找到.当为类似的 COM+ 对象使用 GUID 时，我在 HKEY_CLASSES_ROOT\CLSID\{...}\TypeLib 中找到它们(..."是另一个组件的 GUID).到EventPackage.IEventListener对应的注册表键名，发现没有\TypeLib子键.正如您可能怀疑的那样，在 reg 中搜索0D76C094-21A6-4E04-802B-6E539F7102D7"不会产生任何结果.

When I search the registry for this Guid, I find nothing. When using GUIDs for similar COM+ objects, I find them in HKEY_CLASSES_ROOT\CLSID\{...}\TypeLib ("..." being the GUID of the other component). When I go to the registry key name corresponding to EventPackage.IEventListener, I find that there is no \TypeLib subkey. As you might suspect, searching the reg for "0D76C094-21A6-4E04-802B-6E539F7102D7" yields no results.

所以我知道这一定是注册表问题，但我似乎尝试了我找到的所有谷歌结果.我试过 Regasm 和 regsvcs .exe 无济于事.很多页面只是告诉我，将dll拖到COM+管理器中应该会自动注册组件.

So I know this must be a registry problem, But I have tried seemingly every google result I have found. I have tried Regasm and regsvcs .exe's to no avail. Many pages just tell me that dragging the dll to the COM+ manager should automatically register the component.

那么如何注册类型库?

1. 运行 VB6->VB.NET 向导

然后我在 assemblyinfo.vb 文件中添加了一些行

Then I added some lines to the assemblyinfo.vb file

1. 添加了 Imports System.EnterpriseServices
2. 添加了 Imports System.EnterpriseServices
3. 导入 System.Data.SqlClient
4. <程序集:CLSCompliant(True)>
5. 用于强名称
6. (其中..."是旧组件的 COM+ CLSID)

1. added Imports System.EnterpriseServices
2. added Imports System.EnterpriseServices
3. Imports System.Data.SqlClient
4. <Assembly: CLSCompliant(True)>
5. <Assembly: AssemblyKeyFileAttribute("...")> for a strong name
6. <Assembly: Guid("...")> (Where "..." is the COM+ CLSID of the old component)

我在类文件 IEventListener.VB 中添加了以下内容

I added the following to the class file IEventListener.VB

1. 导入 System.EnterpriseServices
2. _(其中 ... 是正确的 COM+ CLSID，这是唯一的参数)
3. 继承ServicedComponent
4. 将转换向导生成的 ID 更改为正确的值(从 到 _

1. Imports System.EnterpriseServices
2. <ComClass("...")> _ (Where ... is the proper COM+ CLSID, that is the only argument)
3. Inherits ServicedComponent
4. changed the ID made by the Conversion wizard to the proper value (from <System.Runtime.InteropServices.ProgId("IEventListener_NET.IEventListener)> to <System.Runtime.InteropServices.ProgId("EventPackage.IEventListener")> _

然后我将 DLL 拖到适当的 COM+ 应用程序中的 COM+ 管理器中(尽管未指定路径"，仅显示 mscoree.dll)

Then I dragged the DLL into the COM+ manager in the proper COM+ application (although, the "Path" is not specified and only says mscoree.dll)

推荐答案

我认为这里的问题是您没有为 .NET 组件生成类型库.我知道你说过你使用过 regasm - 但你使用了正确的命令行吗?

I think that the problem here is that you haven't generated a type library for your .NET component. I know you said you used regasm - but did you use the right command line?

• 开始菜单 => 程序 => Microsoft .NET Framework SDK vX.Y => SDK 命令提示符.
• 在此命令行中，键入:regasm/tlb:Mydll.dll

• Start Menu => Programs => Microsoft .NET Framework SDK vX.Y => SDK Command Prompt.
• In this command line line, type: regasm /tlb:Mydll.dll
