Have you tried registering the COM DLL using <a href="http://en.wikipedia.org/wiki/Regsvr32" rel="nofollow noreferrer"><code>regsvr32</code></a>? I don't know if <code>regasm</code> does this automatically but apparently it doesn't.

It sounds like you don't have all the items that your application requires installed or working on the server. Some things to look at are:

<ol>
<li>Is the .NET Framework installed?</li>
<li>Make sure COM is working. Some fundamental things to try are: 

<ul>
<li>Inserting an object in a WordPad document.</li>
<li>If you can run WSCript, run a simple vbscript that creates an object.</li>
<li>Run <a href="http://www.dependencywalker.com/" rel="nofollow noreferrer">Dependency Walker</a> on your EXE and make sure you have everything you need.</li>
</ul></li>
<li>If the above doesn't get you going you can use <a href="http://technet.microsoft.com/en-us/sysinternals/bb896645.aspx" rel="nofollow noreferrer">Sysinternals ProcMon</a> to watch what files and registry entries your application is accessing (and maybe not finding). This should give you clues as to what is going on.</li>
</ol>

blocks|key|330244|text|不能使用Regsvr32.exe，需要Regasm.exe。您必须使用/codebase命令行参数运行它，或者在GAC中安装该程序集。我想这就是你的问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|330245|这类注册问题总是令人尴尬的，尤其是因为它们需要安装程序而不是Xcopy.exe。如果版本不正确，则调用DLL+Hell。如果你不使用GAC，你就不会这样做。请考虑改用包含该元素的清单。接受谷歌的第一次点击。|330246|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

You can't use Regsvr32.exe, Regasm.exe is required. You must either run it with the /codebase command line argument or install the assembly in the GAC. I assume that's your problem.

These kind of registration issues are always fugly, not in the least because they require an install program instead of Xcopy.exe. And invoke DLL Hell if you don't version correctly. Which you won't if you don't use the GAC. Consider using a manifest instead that contains the &lt;clrClass&gt; element. Take the first Google hit.

I've used a tutorial (<a href="http://support.microsoft.com/kb/317535" rel="nofollow noreferrer">http://support.microsoft.com/kb/317535</a>) to create a VB.NET Class that exports a COM visible method for calculating MD5 checksums.

The problem is that I need to call this .dll from a language similar to VB (Extra Basic) and it only supports COM calls. On my machine everything works like a charm, but on the destination server it doesn’t work at all. I get "Object creation failed" from the "VB like" application. 

According to the tutorial the only thing one need to do is to use regasm to register the .dll. This doesn't work. I have obviously made something wrong when I registered the .dll.

What do VS2005 do to make this .dll visible for COM calls? 

I have tried to uese regsvr32, but it faild to register the .dll with the following message: "xxx.dll was loaded, but the DllRegisterServer entry point was not found. This file can not be registered"

我使用了一个教程()来创建一个VB.NET类，该类导出一个COM可见的方法来计算MD5校验和。问题是我需要从一种类似于VB (Extra Basic)的语言调用这个.dll，而且它只支持COM调用。在我的机器上，一切都运行得很好，但在目标服务器上，它根本不起作用。我在“类VB”应用程序中看到“对象创建失败”。根据本教程...
