WindowPanes_X32 - Version 1.0 WindowPanes_X32 allows to add "paned" windows to your application. These window panes are a great way to set your application apart from the rest. Each pane has a resizeable "sash" that the user can move around, which will increase or decrease the size of the window panes. Controls contained within each pane are automatically resized. This control was designed to work with VB5 or VC 5 or greater, or any ActiveX container capable application.
