The System cannot find the file specified 2

[IAdams]

To All,

I am using Delphi 6 and trying to consume a COM object created by VS 2005 C#. I can successfuly create the DLL in VS, export it to a TLB file and import the TLB into Delphi. But when I try to instantiate a new class from the COM using Co(Classname).Create, I get the above error.

I have no idea what file it could be looking for; the TLB is absorbed into the Delphi code as a .pas file.

Any ideas, thanks.

some questions:

did u register the COM DLL? (regsvr32 <dllname>)

if so, does it still exist in the path from where it was registered?

Thanks for your quick response.

Yes, I registered it with the command line VS function gacutil.exe which, as I understand, does the job of registration and also puts it in the GAC, right? Then I run a utility calle tlbexp which builds the TLB file.

All is well and Delphi can see the classes and methods inside the TLB and it compiles correctly, etc. but when I run I get the 'file' error.

Just puzzled...

IAdams,

gacutil.exe places the item in the GAC. The tool for registering the dll is regasm.exe (see

http://msdn.microsoft.com/en-us/library/tzat5yw6(VS.80).aspx).

Microsoft provide OleView.exe (

which is a useful tool for seeing what COM classes are available on your system.

I finally got this to work with a TLB file consumed by Delphi. I'm not sure what caused the initial 'file not found' error, but I added some more functionality to the .NET dll and it started working. I had to put GUID information on every Class and Interface within the .NET dll to make them COM-visible. I never used regasm but it works anyway, I just run gacutil and tlbexp...

The .NET dll is just a wrapper for another COM we obtained that didn't have a very good interface with Delphi 6. So now the real work of tying it all together begins.

Thanks for your time and the informative hyperlinks.
