Hi there use : using System.Runtime.InteropServices; and in the class (propably a static helper class) [DllImport ("user32.dll")] public static extern long DestroyWindow (long hWnd); and from your program call : MyStaticHelper.DestroyWindow (this.Handle); Hope that helped Nassos GanDad

Add the dll into ur project, add a reference to that dll, Create an object of the class in the dll, and call the methods of that class. Regards, Pramod

I suggest you read the question more carefully next before you give wrong advise.

But that is how i have used a dll created in VC++. I knew that method, so i adviced. May be that is wrong for him, but no one perfect here, This is an open forum and everyone is here to help each other, whatever they can. it's not necessary that the answer has to be the perfect one There are many ways to do one single thing. Hope u get it. If you can't give solutions u r not supposed to say wrong to anyone. Got it!!! Pramod

Your methods will work for COM dll's only. VS just writes a COM Wrapper for you.

That is certainly true, but his point was that he's not supposed to be afraid to post a reply to someone's question just cause his answer might not be 100% correct. This is not medical advice being given here. There is no law being broken if someone gives mistaken advice. This is a community forum where people are encouraged to contribute. There is no rule that tells people that their contributions are not welcome unless they are perfect.

I agree wholeheartidly, I responded because he seemed surprised that his answer was taken as incorrect without explaination as to the problem! Notice i didnt chastise him for responding with what he thought was a good answer - that was somebody else!
