I've got a c# assembly which I'm invoking via COM from a Delphi (win32 native) application. This works on all the machines I've tested it on, except one. The problem is that the Delphi application gets "Class not registered" when trying to create the COM object. Now, when I look in the registry under HKEY_CLASSES_ROOT\DelphiToCSharp\C...
Hi, I'm running msbuild from a nant script, the problem is that when it tries to register one of my assemblies for com interop, the script just stops, like it's stuck. If I run regasm.exe on the assembly it succeeds. Even if I run msbuild itself from the command-line, with the exact same parameters, it builds successfully. Any ideas o...

I have a dll that's registered for com interop, so under HKLM\Software\Classes\CLSID[my guid]\InprocServer32[my version no]\Codebase it has the path of the registered dll. However, I've rearranged my folder structure so that path is no longer correct. Is there a way of unregistering that dll without putting it back, then unregistering, t...
Hi Everyone, I'm running into some trouble calling a .net assembly from vb6 and was hoping SO could help. In VB.net I built a ComClass and kept the default constructor and GUIDs.

Hey everyone, I'm writing a class-library (IE BHO) in C# and currently wrangling with the large volume of what I think is junk output coming from REGASM's generated registry keys. The short version is this: I only want to expose a handful of classes (currently: ONE class) to IE (and the rest of COM). Only one class has the ClassInterf...

I have a managed assembly containing a few classes, and those classes have overloaded methods. I expose the assembly to COM/IDispatch callers via [ComVisible(true)] ..and also setting the proper Guid, on the assembly itself. I do not define an explicit interface for the COM interop. It's all done dynamically. I run regasm.exe /codeb...
I have just made an update to a dll that is called from VBA within Powerpoint. All development went fine, but when I tried to deploy on another users machine I get a problem that I have no idea how to debug. What happens is that when the .Net object is created in the VBA, the reference that is returned is to the wrong object, so the ne...

Hi I'm attempting to expose our library via COM but seem to be fighting the tools more than the actual problem. Regardless of how I write my COM exposed class I get the warning: "XXX.dll does not contain any types that can be registered for COM interop" (marked project as Register for COM interop in the project properties). Even the sim...
