### Description

Returns the Window Reference for a window specified by the Index parameter.  
The Window Reference is a unique ID handed out by the operating system. It is used by the rest of the [WebView](component_WebView.md) functions Caution: Passing 0 for Index will grab the front most window which should be your FileMaker window, but it could be any window including dialogs. This is a particular problem with the "Data Viewer" which is always in the front. [Window.FindByTitle](WindowFindByTitle.md) was added to version 1.1 as a more reliable way of getting the Window.Ref.  
The window reference is only valid until the window is closed.
