Screen Orientation Modes

4/19/2010

Windows Mobile allows users to view applications in either portrait or landscape mode and to switch between the two modes at any time. This means that developers might need to program applications with the ability to detect screen rotation events and to respond to those events appropriately. The topics in this section provide the necessary background, technical details, and design guidelines to help you adapt your application for the different modes.

In This Section

• Rotation Behavior in Older Applications
  Provides possible behavior scenarios when older applications are rotated into landscape mode.

• How Applications Detect and Respond to Screen Rotation
  Describes the programming mechanism that signals a screen rotation and explains how to use it.

• WM_SETTINGCHANGE Code Example
  Illustrates how a typical application detects and handles screen rotation using the WM_ SETTINGCHANGE message.

• WM_SIZE Code Example
  Illustrates how a typical application detects and handles screen rotation using the WM_SIZE message.
