VB6 automation error trying to use a COM-exposed C# DLL P: n/a Tremendo Hi, I have 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 and built a C# DLL (see code http://stackoverflow.com/questions/1487406/vb6-automation-error-on-calls-to-net-3-5-assemblies-after-the-first-calls 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 a reference to the ..tlb. So far, everything seems to be https://bytes.com/topic/visual-basic-net/answers/598457-vb6-automation-error-trying-use-com-exposed-c-dll 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?

See more: VB6 .NET COM Interop Question: Does anyone know why I can get the events to fire between a .net usercontrol and a VB6 Form hosting the user control through VBControlExtender in a reg free com environment? The VB6 end does not seem to recognise the .net user control as an event source and is consequently not calling Advise. I am for the most part successfully running a vb6 exe with .net components using Com interop without COM registration using sxs reg free COM manifests. My VB6 exe uses many vb activex controls without registration with no problems, however I can only get .net user controls hosted in the VB6 exe using VBControlExtender to work one way, i.e. the control events do not fire. If I register my dll as follows regasm mydotneusercontrol.dll the events fail to fire If I register my dll with a type library as follow regasm mydotneusercontrol.dll /tlb:mydotneusercontrol.tlb The events fire If I use a sxs manifest and don't register mydotneusercontrol.dll my user control is hosted in the vb6 form but again
