Window.OnWindow property (Excel)
Returns or sets the name of the procedure that's run whenever you activate a window. Read/write String.
Syntax
expression.OnWindow
expression A variable that represents a Window object.
Remarks
The procedure specified by this property isn't run when other procedures switch to the window or when a command to switch to a window is received through a DDE channel. Instead, the procedure responds to the user's actions, such as choosing a window with the mouse.
If a worksheet or macro sheet has an Auto_Activate or Auto_Deactivate macro defined for it, those macros will be run after the procedure specified by the OnWindow property of the Application object.
Example
This example causes the WindowActivate procedure to be run whenever window one is activated.
ThisWorkbook.Windows(1).OnWindow = "WindowActivate"
