the nay-sayers will say that you should *never* put the outputs of a 
tool in source control. However with interop dlls I think you can go 
either way. If the underlying dll isn't going to change very often then 
I don't see any harm in generating the wrapper once and using it each build.

<xsl:for-each select="../../References/Reference">
        <xsl:choose>                                      
                <xsl:when test="@WrapperTool='tlbimp'">
                        <script language="C#">
                                <code>
				[System.Runtime.InteropServices.DllImport(
"oleaut32.dll", CharSet =
System.Runtime.InteropServices.CharSet.Auto, PreserveSig =
false,SetLastError=true )] 
				private static extern void
QueryPathOfRegTypeLib( ref Guid guid, Int16 wVerMajor, Int16 wVerMinor,
Int32 lcid,
<script snipped >
... And so on

Is there a better way to find the path for the COM object to be wrapped?
 

wow - I'm impressed, thats quite a cool way to lookup the location. You 
could manually account for all the dlls that need wrapping and do that 
in a seperate script. However if automating the conversion from vs 
projects is going to be a standard part of your build process then it 
seems as good a way as any. Is there any reason you decided not to use 
the solution task ? or did someone ask you that already ?

Is this a good way to do this?

Thanks. I created new wrapper DLL's using the AXIMP tool. These do have the
names that Nant expects. I don't know how the old wrapper DLLs were created.
The developers who programmed the app have left the company so I can't ask.
Let's forget about it.

Subject: [Nant-users] references to interop dll's
I am running into the following problem:
I use a nant script that has produces an exe. It has a references to 
Interop.TGXLib.dll and AxInterop.TGXLib.dll (wrapper dll's).

Everything compiles fine.
Now, when I run the program I just compiled, it is looking for dll's 
TGXLib.dll and AxTGXLib.dll, but it can't find them because these
   

names
 

are wrong, it should look for Interop.TGXLib.dll and 
AxIntererop.TGXLib.dll.

   

no - this is incorrect. the interop dlls are wrappers for the 
non-interop ones. You need both to be available at runtime. The interop 
ones should be in the same directory as you app ( or somewhere loadable 
by .net ) while the com dlls ( TGXLib.dll and AxTGXLib.dll )  will need 
to be registered using regsvr32 or some other com registration method.

 

If I rename my interop dll's to TGXLib.dll and AxTGXLib.dll,
   

everything
 

works fine.
   

I find that very surprising - if they are true interp dlls. I think as 
Gert said, you had better package up a sample.

 

So the names of the references in the exe are wrong. The part
   

'interop.'
 

has dropped off.
