Private Sub Form_Load() Dim score1 As ComWeightedScore Set score1 = New ComWeightedScore score1.Score = 500 End Sub On the line Set score1=new ComWeightedScore the exception Automation Error is raised. It can hardly be any simpler than this... Where is the error?! .net vb6 com-interop share|improve this question edited Aug 29 '11 at 4:07 asked Aug 28 '11
since installing .NET 2.0 Framework .NET Framework > Common Language Runtime Internals and Architecture Question 0 Sign in to vote I noticed that a VB 6 app is no longer able to properly call a .NET component exposedwith aCOM interfacethat was compilevia Visual Studio 2005, it raises an Automation error. Setting the application configuration file to point to the .NET framework v2.0.50727 does not help the situation.However, when the .NET component is compiled viaVisual Studio 2003 it works provided I have the infamous application configuration for the VB6 app set to:

VB6 automation error trying to use a COM-exposed C# DLL P: n/a Tremendo Hi, https://winscp.net/forum/viewtopic.php?t=13590 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 automation error PC1 I wrote 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 automation error in project, and added 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?
