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.

Does it still fail if you remove the assignments from the body of the constructor? Also, provide more info and details on the error you get. &ndas

VB6 automation error trying to use a COM-exposed C# DLL P: n/a https://winscp.net/forum/viewtopic.php?t=15228 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 automation error installed separately. On 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 automation error the 6, I created a new 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?
