Examples

The following code example displays the Count of the Buttons before and after the Clear method is called. This code requires that a ToolBar with at least one ToolBarButton has been created.

public:
   void ClearMyToolBar()
   {
      int btns;
      // Get the count before the Clear method is called.
      btns = toolBar1->Buttons->Count;
      toolBar1->Buttons->Clear();
      MessageBox::Show( "Count Before Clear: " + btns.ToString() +
         "\nCount After Clear: " + toolBar1->Buttons->Count.ToString() );
   }

public void ClearMyToolBar()
 {
    int btns;
    // Get the count before the Clear method is called.
    btns = toolBar1.Buttons.Count;
    toolBar1.Buttons.Clear();
    MessageBox.Show("Count Before Clear: " + btns.ToString() +
                    "\nCount After Clear: " + toolBar1.Buttons.Count.ToString());
 }

Public Sub ClearMyToolBar()
    Dim btns As Integer
    ' Get the count before the Clear method is called.
    btns = toolBar1.Buttons.Count
    toolBar1.Buttons.Clear()
    MessageBox.Show("Count Before Clear: " + btns.ToString() & _
        Microsoft.VisualBasic.ControlChars.Cr & "Count After Clear: " & _
        toolBar1.Buttons.Count.ToString())
End Sub

Remarks

The Count property holds the actual number of ToolBarButton controls assigned to the collection. It is common to use the Count property value as the upper bounds of a loop to iterate through a collection. The index value of a collection is a zero-based index, so you must subtract one from the looping variable otherwise you will exceed the upper bounds of the collection and throw an exception.
