PDA Screen Orientation (Pocket PC, PDA Module)

Determines if the orientation of the screen on the PDA target changed while the PDA application was running. This VI also returns the height and width of the screen on the PDA target. This VI is supported only for PDA targets that support the ability to change screen orientation while an application is running.

Note  Use the PDA Get Screen Size VI if you only need to determine the height and width of the screen on the PDA target.

Details  

	error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the PDA Error Handler VI to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node. status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE. code is the error or warning code. The default is 0. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code. source specifies the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
	orientation changed? returns TRUE if you change the orientation of the screen on the PDA target.
	width is the width of the screen in pixels.
	height is the height of the screen in pixels.
	error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred. code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code. source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning.

PDA Screen Orientation Details

This VI polls the PDA application for the last state. If a user changes orientation multiple times, the orientation might be the same as when the PDA application started, but the orientation changed? output parameter is TRUE. Use the width and height output parameters to determine the actual orientation of the PDA screen.
