The ClientToHostWindow event enables the host application to adjust the size of the WebBrowser control window that allows for user interface items such as a toolbar, menu bar, or address bar.

This event is fired when a new window is opened through scripting, using the open method.

The following example indicates how the ClientToHostWindow event can be handled.

Private Sub WebBrowser1_ClientToHostWindow(CX As Long, CY As Long)
    If (bToolbarVisible) Then
        CY = CY + iToolbarHeight
    End If
    If (bStatusbarVisible) Then
        CY = CY + iStatusbarHeight
    End If
End Sub

This event is available only to an application that is hosting the WebBrowser control installed by Microsoft Internet Explorer 5.5 and later.
