Hi All,

Here is my problem :

I use C#.net to write a class library project. In the class, i need to display some message on the screen, say, some warning or error message. However, in a class library, there is no System.Windows namespace. So how can i do that ? i'd like to have such func like messagebox, i.e, not only display message but also allow user to make choice, in a class library project, is that possible ?

Thanks in advance
