IMAQ WindNonTearing VI

Owning Palette: External DisplayInstalled With: NI Vision Development Module

Allows you to configure the non-tearing functionality of a display window. Tearing images can occur when the image display rate is not synchronized with the refresh rate of the monitor. The difference between the display rate and the monitor refresh rate can cause parts of two different images to be displayed at the same time, which results in a split in the displayed image. By enabling non-tearing, the image display is synchronized to the refresh of the monitor and tearing is eliminated.

Window Number selects the window to configure. The default is 0.

NonTearing? (True) enables non-tearing on a display window when TRUE and disables non-tearing when FALSE. The default is TRUE.

error in (no error) describes the error status 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 Simple Error Handler or General Error Handler VIs 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. 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. The default is an empty string.

Set / Get (Set) specifies whether you want to retrieve or configure the non-tearing functionality of the window. The default value is TRUE (Set).

NonTearing? Out is the status of the non-tearing functionality for the specified display window.

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. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.

	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. The default is an empty string.
