PPT97: How to Use the WindowState Property

ID: Q162352

The information in this article applies to:

Microsoft PowerPoint 97 for Windows

SUMMARY

This article describes how to use the WindowState property from within a Microsoft PowerPoint macro.

MORE INFORMATION

The WindowState property stores information about the window such as whether the Window is maximized, minimized, or normal. Two types of windows use the WindowState property: ActiveWindow (the presentation) and Application (PowerPoint). The following constants are used to describe the different 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.

The following sample Microsoft Visual Basic for Applications code retrieves the 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 to indicate that they are long data types.

Setting a WindowState

The following Visual Basic example sets a WindowState for the ActiveWindow and 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 currently the ActiveWindow.

To determine whether a WindowState is a particular state, you can add the following code to your macro:

   If ActiveWindow.WindowState <> ppWindowMinimized Then
      ActiveWindow.WindowState = ppWindowMinimized
   End If

This code example changes the WindowState only if the ActiveWindow is not already minimized. If the ActiveWindow is minimized, the code continues after the End If statement.
