title: Visual Basic Problems
body: <p>I am trying to create a program that would function as a "shopping list". I have completed all the code and setting it up and what not but when I try and run the program it will not run. I have 0 errors in my code and it will not debug either. There are two programs I am having this problem with. Here is the code for both of the programs.<br>
  PROGRAM 1:   </p>
  
  <pre><code>Public Class Form1
      Dim Item As String = txtAdd.Text
      Private Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd.Click
          Item = Me.txtAdd.Text
          Me.lstItems.Items.Add(Item)
      End Sub
      Private Sub btnMoveToList_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnMoveToList.Click
          Me.lstItems.Items.Remove(Item)
          Me.lstList.Items.Add(Item)
      End Sub
  Private Sub btnMoveToItems_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnMoveToItems.Click
      Me.lstList.Items.Remove(Item)
      Me.lstItems.Items.Add(Item)
  End Sub
  Private Sub btnDelete_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDelete.Click
      Me.lstItems.Items.Remove(Item)
  End Sub
  End Class   
  </code></pre>
  
  <p>PROGRAM 2:   </p>
  
  <pre><code>Public Class Form1
      Dim total As Double
      Dim Cost As Double = Me.txtCost.Text
      Dim Number As Integer = Me.txtNumber.Text
  
  
      Private Sub btnCalculate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculate.Click
          total = (Cost * Number)
  
          If Int32.TryParse(Me.txtCost.Text, Me.txtNumber.Text) Then
              MessageBox.Show("The total cost of your items is:" &amp; total)
          Else
              MessageBox.Show("Enter correct numeric values")
          End If
      End Sub
  
      Private Sub ExitToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ExitToolStripMenuItem.Click
          Application.Exit()
      End Sub
  End Class
  </code></pre>
  
  <p>I am receiving a pop up window that says "An error occurred creating the form. See Exception.InnerException for details.  The error is: Object reference not set to an instance of an object."</p>
