COM异常 - TYPE_E_CANTLOADLIBRARY？ [英] COM Exception - TYPE_E_CANTLOADLIBRARY?

问题描述

我用我的.NET Web应用程序中的COM DLL。这适用于多个不同的机器上的罚款。结果
但是一个特定的机器上，我得到以下错误：

I am using a COM dll in my .Net web application. This works fine on multiple different machines.
However on one particular machine I get the following error:

无法投类型的COM对象CServer.CApplicationClass接口类型CServer.ICApplication。此操作失败的原因是对IID{CF0DFA28-046B-4C7D-8AA9-F4B7477D8CAE}接口的COM组件调用QueryInterface失败，原因是以下错误：错误加载类型库/ DLL。 （从HRESULT异常：0x80029C4A（TYPE_E_CANTLOADLIBRARY））。

Unable to cast COM object of type 'CServer.CApplicationClass' to interface type 'CServer.ICApplication'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{CF0DFA28-046B-4C7D-8AA9-F4B7477D8CAE} ' failed due to the following error: Error loading type library/DLL. (Exception from HRESULT: 0x80029C4A (TYPE_E_CANTLOADLIBRARY)).

我已经registerd使用 REGSVR32 命令的DLL。结果
我也创建了这个DLL COM +应用程序。
通过运行注册表结果搜索
我可以找到许多地方的关键。
我也曾尝试注销DLL和删除计算机上的所有referneces这个DLL。事后重新添加DLL并重新注册它。

I have registerd the dll using the regsvr32 command.
I have also created a COM+ application for this dll. Running a search through the registry
I can find the key in numerous places. I have also tried unregistering the dll and deleting all referneces on the computer to this dll. And afterwards re-adding the dll and re-registering it.

我写这些测试DLL一个简单的Windows脚本文件。这工作得很好。然而，问题是在IIS中运行我的.NET项目存在。

I have written a simple windows script file which tests the dll. This works fine. However the problem exists in my .net project which is running in iis.

谁能帮我？..

推荐答案

我也有类似的问题，用TYPE_E_CANTLOADLIBRARY消息。

I had a similar problem, with the "TYPE_E_CANTLOADLIBRARY" message.

背景：
我用这一个Interop.ReferenceA.dll项目。此文件是使用TLBIMP ReferenceA.dll /创建出来。Interop.ReferenceA.dll

Background: I had a project which used Interop.ReferenceA.dll. This file was created using tlbimp ReferenceA.dll /out: Interop.ReferenceA.dll.

解决方案：
当我使用RegDllView看了看ReferenceA.dll我注意到ReferenceA.dll有一个子类，这是在错误消息中显示的IID。
我在子类的源$ C ​​$ C环顾四周，发现它有一个依赖于Interop.ReferenceB.dll。

Solution: When I took a look at ReferenceA.dll using RegDllView I noticed that ReferenceA.dll had a subclass, which was the IID shown in the error message. I looked around in the source code of the subclass and noticed that it had a dependency to Interop.ReferenceB.dll.

原来，需要Interop.ReferenceB作为一个类型库子类的工作。于是我就这样的：

Turns out that the subclass needed Interop.ReferenceB as a type-library to work. So I ran this:

regasm /tlb:Interop.ReferenceB.tlb Interop.ReferenceB.dll（使用regasm的32位版本。）

regasm /tlb:Interop.ReferenceB.tlb Interop.ReferenceB.dll (the 32-bit version of regasm was used.)

和错误走了。
