In C# 3.5 I'd have to write something like Type comObjectType = Type.GetTypeFromProgID(progId, true); Activator.CreateInstance(comObjectType); Is there an easier way to do it in C#...

I have a C# method that is calling a C++ method. The C++ method uses WMI, so it calls CoInitializeEx(0, COINIT_MULTITHREADED) and then CoInitializeSecurity etc... before making the WMI select. My Problem, CoInitializeEX if failing with code 2147417850 (RPC_E_CHANGED_MODE) I tried to create a new STA thread from c# and call the c++ meth...
I'm creating a COM type library with over one hundred interfaces. Defining all of the interfaces and coclasses in a single library is unreasonable... the IDL file becomes thousands of lines long! So I'm trying the idea of putting each interface in its own file, and using imports to satisfy its dependencies. What strategies can I use to ...
I have two questions. 1)Does Windows Phone 7 support COM? .NET Framework knows such attributes like ComVisible, but I am not sure after all. 2)System.Runtime.InteropServices.Marshal misses any COM functions. Particularly, if the first question is answered positive, I miss StringToBSTR and GetObjectForNativeVariant. I am sure both funct...

I want to write a Delphi function to register a dll. I want the function to check if OleInitialize has already been called before it does so. I guess I'm trying to avoid the consequences of initializing twice because I'm not sure what they might be. I'm worried that my function won't handle as wide a variety of dlls as regsvr32.exe. ...
