I have registered 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 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 16k74378 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 file

Automation Error Element Not Found Vb6
two PCs: PC1: Visual Studio 2005 (including .NET framework 2.0. PC2: Visual Studio 6 (using Visual Basic 6) + .NET framework 2.0 installed separately. On PC1 I wrote http://stackoverflow.com/questions/11973212/automation-error-with-interop and built a C# DLL (see code below), and created one .tlb and one .reg file to expose its methods to COM. On PC2 I copied the .dll, .tlb and .reg into WINDOWS\system32, and executed the .reg to insert new entries to the registry. In Visual Basic 6, I created a new project, and added https://bytes.com/topic/visual-basic-net/answers/598457-vb6-automation-error-trying-use-com-exposed-c-dll a reference to the ..tlb. So far, everything seems to be ok. I can see the class in the object inspector, and browse its methods and enumerations. Also, the tool that shows as I type the valid methods and parameters works ok. Compilation to exe works fine. Problems start at run time. Just trying to instantiate one instance of the COM exposed class gives me a "Run-time error '-2147024894 (80070002) Automation error'". See VB6 code below, too. Both listings have dummy code. Any hint about what can this be due to?

Wednesday, August 29, 2007 3:09 AM Answers 0 Sign in to vote Hi Dave, When you ran it as an .exe file did you have your .NET Dll in the same directory? On a target machine you need to run regasm (with /codebase if you want a relative path). If you have a dependency on stdole.dll, do you have that in the GAC? (If you don't have it referenced in your .NET project then don't worry about this one). Hope that helps, let me know if you're still having issues with it.

COM, Interop, vb6migration, VB.NET, Vb6, .NET, Visual Basic to .NET// Comments (0) In VB6 when you have an ActiveX Library it was very important to use the BinaryCompatibility setting to make sure that your applications did not break after a change. So let’s first introduce what is binary compatibility and how to accomplish that in .NET. Binary Compatibility allows to make changes to your components or COM classes without recompiling every application you've made that uses the component. And why do you need it. Why compatibility breaks. On lets see. An ActiveX Control or DLL expose Public interfaces. Those interfaces have all of the properties, methods, events, etc. that you've marked as Public. In other words, everything you've added that shows in Intellisense while working outside of your component. Now let's say you have create a class, with two Methods Method1 and Method2 When you compile, VB generates all the COM infraestructure you need for your component. It defines a CoClass and an interface and an entry for each method. For a vb class with two methods: Sub Method1() End Sub Sub Method2() End Sub It will produce a typelib like: // Generated .IDL file (by the OLE/COM Object Viewer) // // typelib filename:
