This article describes how to use the WindowState property from within aMicrosoft PowerPoint macro.
More information
The WindowState property stores information about the window such aswhether the Window is maximized, minimized, or normal. Two types of windowsuse the WindowState property: ActiveWindow (the presentation) andApplication (PowerPoint). The following constants are used to describe thedifferent window states.

WindowState Constants

The WindowState can be one of the following three ppWindowState constants:
Name of Constant     Description----------------     -----------ppWindowMaximized    Specifies that the window is maximized.ppWindowMinimized    Specifies that the window is minimized.ppWindowNormal       Specifies the window is neither maximized nor                     minimized.				

Retrieving a WindowState

Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. The following sample Microsoft Visual Basic for Applications code retrievesthe current WindowState of the ActiveWindow and the application.
  Sub GetWindowState()      ' WindowState property is a long.      Dim lPowerPointWindowState As Long      Dim lActiveWindowState As Long      ' Retrieve the application window state.      lPowerPointWindowState = PowerPoint.Application.WindowState      ' Retrieve the active window's window state.      lActiveWindowState = ActiveWindow.WindowState   End Sub				
The WindowState property is a Long data type. So, the two variables(lPowerPointWindowState and lActiveWindowState) are declared as longs.

NOTE: The lower case "l" is used at the beginning of the variable names toindicate that they are long data types.

Setting a WindowState

The following Visual Basic example sets a WindowState for the ActiveWindowand for PowerPoint.
   Sub SetWindowState()      ' Minimizes the active presentation.      ActiveWindow.WindowState = ppWindowMinimized      ' Maximizes PowerPoint.      PowerPoint.Application.WindowState = ppWindowMaximized   End Sub				
NOTE: You can only set the WindowState of a presentation that is currentlythe ActiveWindow.

To determine whether a WindowState is a particular state, you can add thefollowing code to your macro:
   If ActiveWindow.WindowState <> ppWindowMinimized Then      ActiveWindow.WindowState = ppWindowMinimized   End If				
This code example changes the WindowState only if the ActiveWindow isnot already minimized. If the ActiveWindow is minimized, the code continuesafter the End If statement.
