Programming Forums - Little help with ListView Boxes

Hey yall. In my newer version of download blocker, I decided to add a Personal Block Settings option, for users to add their own custom programs to block. What I have is this, I have all the open windows in a listview box. Then I would like to it to where when I select the items in the listviewbox, it will tell their classname and iwndow title in textboxes. here is the code I am using

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick

        Dim whPoint = WindowFromPoint(Cursor.Position.X, Cursor.Position.Y)



        GetClassName(whPoint, clsName, Len(clsName))

        GetWindowText(whPoint, wText, Len(wText))



        txtclass.Text = clsName 'GetClassName(whPoint, clsName, 0)

        txtapptext.Text = wText

    End Sub

The

Dim whPoint = WindowFromPoint(Cursor.Position.X, Cursor.Position.Y)

is what gets the windowclass name and window title, but with that. I have to move my mouse over the window I want blocked. I want it to be able where I just select the item out of the listbox and it get all the info, and display it in my txtboxes. But I have tried

Dim whPoint = Listview1.selecteditems

, and a couple more, but I always get a InvalidCastException at:

GetClassName(whPoint, clsName, Len(clsName))

So please help
