The Shape to locate in the collection.
Type: System.Int32
A zero-based index value that represents the position of the specified Shape in the ShapeCollection.
If the shape is not found in the collection, the IndexOf method return value is -1.
The following code example demonstrates how to use the IndexOf method to retrieve the location of a Shape in the ShapeCollection. This example requires that you have at least two OvalShape controls on a form.
Private Sub OvalShape2_Click() Handles OvalShape2.Click
Dim i As Integer
' Find the index for OvalShape1.
i = OvalShape2.Parent.Shapes.IndexOf(OvalShape1)
' If the shape is not in the collection, display a message.
If i = -1 Then
MsgBox("OvalShape1 is not in this collection.")
End If
End Sub
private void ovalShape2_Click(System.Object sender, System.EventArgs e)
{
int i;
// Find the index for OvalShape1.
i = ovalShape2.Parent.Shapes.IndexOf(ovalShape1);
// If the shape is not in the collection, display a message.
if (i == -1)
{
MessageBox.Show("ovalShape1 is not in this collection.");
}
}
