I have registered excel vba automation error the system cannot find the file specified it with regasm (using codebase switch) and added the tlb as a reference to the VB6 project but when I attempt to call it I get the following automation error: -2146232832 (0x80131600) If I register the existing interop dll in exactly the same way and add to my project, it works fine. The only differences I can think of are that the project has since been upgraded from VS8 to VS9 (same .net version though), and

Regasm /codebase

I'm now compiling on a 64-bit machine (which I know there are issues around this). I have set the project to compile as x86 but I still get the automation error. Any ideas?? c# .net com-interop share|improve this question edited Sep 24 '12 at 18:40 Kate Gregory 16.1k74478 asked Aug 15 '12 at 16:29 RRM1000 334 You mean VS2008 and VS2010 I think? –EaterOfCode Aug 15 '12 at 16:33 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote accepted Your C# code is throwing an exception and it isn't being caught. Specifically an ApplicationException. That's an exception that the framework code never throws, it must be located in your C# source code. You'll need to debug the code if you can't locate the problem. Do so with Project + Properties, Debug tab. Select "Start external program" and point it to c:\program files\microsoft visual studio\vb98\vb6.exe. Then Debug + Exceptions, tick the Thrown checkbox for CLR exceptions. You can now press F5 and the VB6 IDE start running. Load your VB6 project and reproduce the problem. The debugger stops at the line of C# code that throws the exception. share|improve this answer answered Aug 15 '12 at 19:08 Hans Passant 655k819631606 Many thanks. Very useful to know how to debug from VB6 into .NET! –RRM1000 Aug 16 '12 at 10:07 ad

I have built these with the swithes for 'COM Interop'. I move this DLL from my VS2008 machine to my VB6 dev machine; run regasm xxx /tlb; and then write a little sample program to test the DLL. The significant parts of the program program are: ------------------------------------------ << reference is added to the dll>> Public M10 As Mar10Class.Mar10Class Private Sub cmdMar10Class_Click() Set M10 = New Mar10Class.Mar10Class M10.HelloMsg ("Mar10 class Msg from the system cannot VB6 ") End Sub --------------------------------------- If I compile the program, it behaves as expected, but if I try to run it in the dev environment, it gets Automation error The system cannot find the specified file The error happens on line "Set M10 = New Mar10Class....." I have thried this with 4 test dlls. The first one I wrote works in both the comile and dev mod. All others only work in compile mode. I moved one of the test projects to another machine that had the VB6 dev environment and on that machine none worked in the dev environ (and all worked when compiled). I can't see anything in the .net source code or project properties that would make a diference. Can anyone shed some light? Much appreciated.
