Can I Create DCOM Server using .net C#.

Please guide me ..

Part 2: 6. Start the DCOM Server application. You can do this by creating a new console application and calling the following code in the Main method: Type type = Type.GetTypeFromProgID("MyDCOMServer.MyDCOMServer"); object obj = Activator.CreateInstance(type); Console.WriteLine("Server running. Press Enter to exit."); Console.ReadLine(); 7. To connect to the DCOM Server from a Windows client, use the CoCreateInstanceEx function to create an instance of the object and call its methods as needed. Here's an example of how to do this in C++: #include #include #include int main() { HRESULT hr = CoInitialize(NULL); if (FAILED(hr)) { std::cerr GetData(42, &bstrData); if (FAILED(hr)) { std::cerr Release(); CoUninitialize(); return -1; } std::wcout Release(); CoUninitialize(); return 0; } This is just a simple example to demonstrate the basic concept of creating a DCOM server. In a real-world application, you will need to add error handling, security, and other features to make sure your server is robust and secure.

Part 1 Code that creates a DCOM server using .NET C#, lets do it step by step: 1. Create a new C# class library project in Visual Studio and add a reference to the COM library you want to use. 2. In the Project Properties window, go to the Build tab and check the "Register for COM interop" option. 3. In the project code, define the classes and interfaces that will implement the functionality you want to expose through DCOM. Use the [ComVisible(true)] attribute to indicate which classes and interfaces should be exposed to COM. [ComVisible(true)] public interface IMyDCOMServer { string GetData(int value); } [ComVisible(true)] public class MyDCOMServer : IMyDCOMServer { public string GetData(int value) { return string.Format("You entered: {0}", value); } } 4. Implement the classes and interfaces as needed to provide the desired functionality. 5. Use the Regasm.exe utility to register your assembly as a COM component. You can do this from the Visual Studio Command Prompt as follows: regasm /tlb MyDCOMServer.dll

Yes, you can create a DCOM Server for Auto Certificate Enrollment using .NET C#. Here is a high-level overview of the steps you can follow: 1. Define the interface for the DCOM server. This will define the methods that the DCOM client can call to request certificate enrollment. 2. Implement the DCOM server by creating a class that implements the interface. 3. Register the DCOM server on the Windows system where it will be running. This involves creating a registry key that points to the executable that contains the DCOM server. 4. Configure the firewall to allow incoming connections to the DCOM server. 5. Configure the CA to issue certificates based on the enrollment requests from the DCOM server. 6. Create a DCOM client that can communicate with the DCOM server and make requests for certificate enrollment.
