Events

Question

Thank You Suman for your reply i have worked on it and got it. I have got an application in unmanaged language which i am trying to convert it into C# manually. That application has got few windows with few controls. i am creating a window for window textbox for textbox but my problem is the events associated with unmanaged applications controls are different from C# controls and there is code in that events sometimes business code. How should i manage these events? Can you help me please? Or should i go for the custom controls, if so will this be of advantage to me? B'coz i dont know the advantages of using custom controls. Any any suggestion is appreciated
