Imports System.Runtime.InteropServices
Namespace ClassLibrary1
Public Class Foo
Shared Function <DllImport("user32.dll")> MessageBoxA (ByVal h As Integer, ByVal m As String, ByVal c As String, ByVal type As Integer) As Integer
End Function
Public Shared Sub Main()
MessageBoxA(0, "Hello World2!", "www.asp888.net", 0)
Console.WriteLine("Hello World!!!")
End Sub
End Class
End Namespace
