Hi All :

I'm VB.Net Beginner I try to create object Dynamically :

In my testing, I create 2 .net project
One is MyApp (Type is windows application) with one button name "Button1"
The another one is "prj01" (Type is Class libary) with one public Class name
"dbLib"

In this prj01.dbLib I create the simple code "

Public Class dbLib
   Public Function SendMsg()
       MsgBox("a")
   End Function
End Class

and success to compile.

In the MyApp.Form1 I create the following Simple code :

Public Class Form1
   Inherits System.Windows.Forms.Form
   Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click
           Dim oCar As Object
          Dim ty As Type = Type.GetType("prj01.dbLib")
           oCar = Activator.CreateInstance(ty)
           oCar.SendMsg()

   End Sub
End Class

However , while I run the project , The object "ty" return NOTHING.

And show error "Value Cannot be Null"

How can fix it

Thanks
