This is the answer I wanted to find in StackOverflow but couldn’t. It turns out to be fairly easy to turn a simple C# dll into a COM dll. To create the C# dll Create a solution with a C# class project. The class should have an interface for the properties/methods and an interface for … Read more
It looks like the perfect solution does not yet exist. To summarize some research: Make My Manifest (link) This tool scans a VB6 project to look for COM dependencies, but it also supports manual declaration of late-bound COM dependencies (i.e. those used via CreateObject). Interestingly enough, this tool puts all information about the dependencies inside … Read more
COM is a mechanism that allows the re-use of objects (or rather components), independently of the languages used by the programmer who implemented the component and the programmer who uses it, and independently of whether the component was implemented in the client’s program or elsewhere on the machine (or network). Broadly speaking, each COM component … Read more
You can add reference of Microsoft.Office.Core from COM components tab in the add reference window by adding reference of Microsoft Office 12.0 Object Library. The screen shot will shows what component you need.
By no means am I an expert in this, but I stumbled recently on what I think you want: the CoClass attribute class. [System.Runtime.InteropServices.CoClass(typeof(Test))] public interface Dummy { } A coclass supplies concrete implementation(s) of one or more interfaces. In COM, such concrete implementations can be written in any programming language that supports COM component … Read more
You are probably looking for System.Guid.NewGuid().
EDIT (3/17/2021) Disclaimer: This answer was written in 2011 and references the original .NET Framework 4.0 implementation, NOT the open-source implementation of .NET. In .NET 4.0, the runtime handles certain exceptions raised as Windows Structured Error Handling (SEH) errors as indicators of Corrupted State. These Corrupted State Exceptions (CSE) are not allowed to be caught … Read more
The COM threading model is called an “apartment” model, where the execution context of initialized COM objects is associated with either a single thread (Single Thread Apartment) or many threads (Multi Thread Apartment). In this model, a COM object, once initialized in an apartment, is part of that apartment for the duration of its runtime. … Read more
