Calling .net library using COM example
To test the sample, follow the steps:
1. Copy the following example as Hello.cs and CallHello.cpp to a folder like c:\temp
2. Open up a Visual studio dos window (to make sure all paths are set correctly)
Start -> Program -> Visual Studio 2005 -> Vistual Studio Tools -> Visual Studio Command Prompt.
[code=BatchFile]
3. cd \temp
4. csc /t:library Hello.cs
5. regasm /tlb /codebase Hello.dll
6. cl CallHello.cpp
[/code]
7. Now you have CallHello.exe to run.
8. You can unregister Hello.dll by regasm /u Hello.dll



// Hello.cs

// 1. Compile with:  csc.exe /t:library Hello.cs

// 2. Register with: regasm.exe /tlb /codebase Hello.dll



using System;

using System.Runtime.InteropServices;



[assembly: ComVisible(true)]

[assembly: System.Reflection.AssemblyVersion("1.0.0.0")]

[assembly: Guid("2b31035b-7575-4980-8ba7-111111111111")]



[Guid("2b31035b-7575-4980-8ba7-333333333333")]

[InterfaceType(ComInterfaceType.InterfaceIsDual)]

public interface IHello                                   // expose as COM interface

{

    [DispId(1)] void SayHello();

}



[Guid("2b31035b-7575-4980-8ba7-222222222222")]

[ClassInterface(ClassInterfaceType.None)]

public class Program : IHello

{

    public void SayHello()

    {

        System.Windows.Forms.MessageBox.Show("Hello from .net");

    }

}



// CallHello.cpp : Defines the entry point for the console application.

// 3. Compile with: cl.exe CallHello.cpp



#include <windows.h>

#include <objbase.h>

#import "Hello.tlb" raw_interfaces_only



int main(int argc, char* argv[])

{

	CoInitialize(NULL);

	printf("Callint .net class as COM (showing a dialog box)");



	Hello::IHelloPtr iHello;

	HRESULT hr = iHello.CreateInstance( __uuidof(Hello::Program) );

	if(SUCCEEDED(hr))

	{

		iHello->SayHello();                       // call .net interface via COM

	}

	CoUninitialize();

	return 0;

}
