fatal error CS0009: Metadata file

[Guest]

You'll have to excuse me if I don't know what I'm talking about, but I'm new to webservices. I'm attempting to compile a C# file with csc /r:dmcorex.dll C:\InetPub\wwwroot\asptest\mtm\OBWebSvc.asmx.cs. dmcorex is in a using statement in the file 'using dmcorex;'. After running this I get the following error:

'c:\WINNT\Microsoft.NET\Framework\v2.0.40607\dmcorex.dll' could not
beopened -- 'There isn't metadata in the memory or stream'

Anyone have any idea what this message means?

Thanks for any help,
Dave

Dave,

Is DMCOREEX.DLL a managed assembly, or is it a COM dll? If it is a COM
dll, then you will have to create an interop assembly and reference that.

Hope this helps.

Dave,

I think that the DMCOREEX.dll is a COM dll. When calling csc.exe, make
the reference to Interop.DMCOREX.dll, and it should work.

Thanks for your info. I guess I'm still trying to figure out terminology

so I'm don't know what a managed assembly is or what a com dll is. I'm
currently am trying to learn more about VS.Net by working in Visual Web
Developer 2005 Express Edition Beta until we get a purchased VS.NET program.
I do think I created an interop assembly (right clicked on project - 'add
references'). In the solutions explorer I can see a 'Bin' folder containing
what seems to be a network symbol followed by 'Interop.DMCOREX.dll'. Is
that what you were talking about? Anyway I still get the error message.

The dmcorex.dll is an API (Onbase Document retrieval) that I access to

call functions in them that returns document lists and documents themselves.
So is that a COM dll?

What exactly is a COM dll?

Please bear with me. I'm very much of novice with VB, C# and web services technology.

Thanks again - I appreciate it,
Dave

Hi Nicholas,

I used the following command:
csc /r:Interop.DMCOREX.dll C:\InetPub\wwwroot\asptest\mtm\OBif.cs
and got a new message:
error CS0006: Metadata file 'Interop.DMCOREX.dll' could not be found

This Interop is in the Bin directory in the same directory as the cs file. That didn't work so I copied into the same directory just in case it was a path thing. It still didn't work. Is there something wrong with my command line?

Thanks again,
Dave

Dave,

the reference to Interop.DMCOREX.dll, and it should work.

I should say the the original message I got in full was ' error CS0246: The type or namespace name 'dmcorex' could not be found (are you missing a using directive or
an assembly reference?). This is what I get now when fully qualifying the assembly.

Thanks,
