Hi Folks

I've noticed that http://channel9.msdn.com/ctpmadness/Default.aspx mentions a July CTP of Visual Studio 2005.

I have spent some evenings testing June CTP and I was just about to switch from Beta 2 to June CTP. But now there is a July CTP on its way, maybe I should wait. The bugs I have reported in Beta 2 seams to be gone with June CTP and it seams more stable that Beta 2, I have not had a crash with June CTP yet, and Beta 2 crashes 3-4 times a day and requires reboot of the machine because of extreme memory use at least once a day.

Does anyone known when July CTP will be available?

Thanks...

After hours of studying the problem, I found the solution. Apparently for databinding to be able to add new rows to the data grid view, the data source has to implement the interface IBindableList. List(Of T) does not implement IBindableList. But I found the class System.ComponentModel.BindingList(Of T) and it just works... Great!

I still haven't found a solution for problem 2)...

Hi,

I'm pressing arrow down when on the last line of the grid, but nothing happens. I wonder if there is an interface or something that I have to implement.

I'll try to fiddle with the different settings and see what happens.

Thanks for your reply...

I have a DataGridView that data binds to an ArrayList (Generics of MyClass1). I have added colums and the objects that already are in the ArrayList are shown just fine.

Problem 1) I cannot seem to add new rows to the grid. There is proberbly som event I have to respond to or something...

I also want a ComboBox to show the same data as the DataGridView (to select a default object from the list of objects).

Problem 2) But when the selected item of the Grid is changed it also changes the selected item in the ComboBox...

Thanks in advance...

This is good news:

Thank you for your replies.

I guess I'll just have to live with it

Hello guys

I have a problem with VB.NET. I get a "specific cast not valid" run-time exception.

Public Class Main
   Public Class A

   End Class

   Public Class B
      Inherits A

   End Class

   Public Sub New()
      Dim TestA As New A
      Dim TestB as B = CType(TestA, B) ' Exception here

   End Sub
End Class

I understand why I get the exception but is there anyway to cast the A instance to a instance of B. I tried to create a new ctor on the B class, trying to set MyBase = TestA... But that does not work. Any ideas?

Thanks Klaus (Denmark)
