Hello.

I have exported the IDL from a OCX file in oder to change some details
(I removed  some classes/interfaces, because they caused errors...).
Then I compiled the IDL to a typelibary (*.TLB) usin MIDL.

Now I want to use this component with my customized tlb in a .net
project.
But when I create a reference to the .tlb file dotnet loads the
original components and seems to ignore the changes I made to the tlb.

What to do now? How can I load/access the component the way I defined
it in the idl/tlb??

Thanks in advance
Sebastian

- remove the old reference
- create an interop assembly with

  tlbimp /out:Interop.XYZ.dll /namespace:Your.Fine.Namespace name.tlb

- add Interop.XYZ.dll as a .NET reference to your project
