toolbar options with multiple forms

[Nick]

Question is How do i declare the "toolNewClient" if its in use by another
form. I'm trying to change the "pushed" property of the toolbar after the
button is clicked. Enclosed is the code for form 1 and 2
Form1:
Public Sub ToolBar1_ButtonClick(ByVal sender As System.Object, ByVal e As
System.Windows.Forms.ToolBarButtonClickEventArgs) Handles ToolBar1.ButtonClick

If e.Button Is ToolNewClient And ToolNewClient.Pushed = False Then
aForm.MdiParent = Me
aForm.Show()
e.Button.Pushed = True

Else

'e.Button.Pushed = False
End If
MessageBox.Show("Please Close New Client Window")
End Sub
End Class

Form2:
Button Click event...

ToolNewClient.Pushed = True
