Question

Entry Point Not Found

Asked by: NigelRocks

Experts,

I have a C# class library that I created that I've used in projects before, but now it won't show up through Intellisense when I try to including with "using".  I tried to register it manually, but it says the entry point can't be found.

Ideas?

Did you add a reference to the DLL within your project?

 

by: NigelRocksPosted on 2009-01-27 at 12:49:52ID: 23480965

Yes.

This .dll won't even register.  The problem exists long before I try to use it in any project at this point.

 

by: p_davisPosted on 2009-01-27 at 12:50:00ID: 23480966

what os? how are you registering it manually? -- you said in your other thread that you installed it to the system32 folder, can you verify that it is actually there. if you type the name of the dll into the run prompt, what happens?

 

by: NigelRocksPosted on 2009-01-27 at 12:52:08ID: 23480998

The file exists in \system32.  I'm attempting to register it using regsvr32.  It tells me it can't find the entry point whehter I try to register or unregister it.

by: p_davisPosted on 2009-01-27 at 12:55:49ID: 23481034

what operating system are you using?

 

by: NigelRocksPosted on 2009-01-27 at 13:15:23ID: 23481204

XP

 

by: emoreauPosted on 2009-01-27 at 13:20:32ID: 23481246

as I wrote in you other question, only COM DLL can be registered and .Net DLLs are not.

 

by: NigelRocksPosted on 2009-01-27 at 13:27:55ID: 23481325

Surely you're not telling me that there's no way I can use a class library created in C# anywhere else?  The surely must be a way to turn a .net dll into a COM dll.

 

by: emoreauPosted on 2009-01-27 at 13:49:30ID: 23481523

You don't have to turn a .Net DLL to use it from a .Net application!

Have you tried the suggestion of my other comment in your other question. It is surely a problem of namespace.

 

by: NigelRocksPosted on 2009-01-27 at 13:55:01ID: 23481590

Is the "entry point not found" error indicative of the fact that it's a .net dll?  Should that message not concern me?

 

by: Jammer59Posted on 2009-01-27 at 13:59:42ID: 23481636

Examine your working project and it's references to identify the differences.  I still think you are missing a reference to the dll.

 

by: NigelRocksPosted on 2009-01-27 at 14:02:32ID: 31539667

The problem was actually a corrupt project file.  Once I fixed that, everything went back to normal.  Is this IDE a pain in the ass or what?

Emoreau gets points for reinforcing my knowledge of .net dlls versus com objects.
