这是什么错误VB6是什么意思？

What does this error mean in VB6?

Function or interface marked as restricted, or the function uses an Automation type not supported in Visual Basic.

我不断收到它时，我打电话与Windows XP及以后（在SYSTEM32称为upnp.dll）一个dll的特定方法

I keep getting it when i call a particular method of a dll that comes with windows xp and beyond (in system32 called upnp.dll)

任何人任何想法？谷歌是没有帮助的。

Anyone any ideas? google wasn't helpful

推荐答案

这是声明FindByType（）从类型库中检索：

This is the declaration for FindByType() as retrieved from the type library:

    HRESULT FindByType(
                    [in] BSTR bstrTypeURI, 
                    [in] unsigned long dwFlags, 
                    [out, retval] IUPnPDevices** pDevices);

请注意第二个参数，unsigned long类型。 VB6不支持无符号类型。这是不是在VB.NET或C＃中的问题，他们都支持他们。

Note the 2nd argument, unsigned long. VB6 doesn't support unsigned types. It is not a problem in VB.NET or C#, they do support them.

这个问题是可以解决的，如果你有安装了Windows SDK。你应该有，如果你有一个最新版本的Visual Studio。使用Visual Studio命令提示符，然后：

This problem is fixable if you have the Windows SDK installed. You should have it if you have a recent version of Visual Studio. Use the Visual Studio Command Prompt, then:

运行OLEView.exe这类C： WINDOWS SYSTEM32 upnp.dll 键入Ctrl + A，按Ctrl + C复制型库的内容 运行的notepad.exe，按Ctrl + V。搜索签名，并删除它。有两个。 将文件保存到一个名为upnp.idl 系统临时目录 运行MIDL upnp.idl / TLB upnp.tlb 复制生成的upnp.tlb到项目目录 run oleview.exe c:windowssystem32upnp.dll type Ctrl+A, Ctrl+C to copy the type library content run notepad.exe, Ctrl+V. Search for "unsigned" and delete it. There are two. save the file to a temporary directory with the name upnp.idl run midl upnp.idl /tlb upnp.tlb copy the generated upnp.tlb to your project directory

您现在可以添加，而不是upnp.dll upnp.tlb，你应该不会再出现错误。   -

You can now add upnp.tlb instead of upnp.dll, you should no longer get the error. -
