   Can someone explain this new-to-visualbasic programmer why my statement   
   throws an exception?   
      
   I have defined a class:   
   Class myDataSet   
       Inherits System.Data.DataSet   
       Public Sub fun(ByVal someparm As String)   
           dosomething()   
       End Sub   
   End Class   
      
   And I created a webservice function that returns a System.Data.DataSet   
   I try to stuff this dataset into my own dataset-type   
   dim myDataSet mds as myDataSet = new myDataSet   
   'mds = dswebsvc(arg) ' vbcompiler does not allow this but rather:   
   mds = CType( dswebsvc(arg), myDataSet) ' compiler allows this   
      
   But at runtime, this statement throws an exception with the message:   
   Unable to cast object of type 'System.Data.DataSet' to type 'myDataSet'   
      
   To overcome this problem I tried to overload the CType() function in the   
   myDataSet class but that is not allowed since apparently the compiler   
   automatically generates this overload!   
      
   What can I do to get rid of this nasty exception?
