VDG_Attribute

This VI gets or sets any attribute for the selected video format.

Get/Set (Get) selects whether you want to Get or Set an attribute. If you enter the number listed to the left of the choices below in the box to the right of the Get/Set (Get) control and click Enter, the choice will appear in the control. You can also use the up and down arrows to the left of the control to select your choice.

Attribute selects which attribute to Get or Set.
Set value is the attribute value to be set.
error in is a cluster that describes the error status before this VI executes. If error in indicates that an error occurred before this VI was called, this VI may choose not to execute its function, but just pass the error through to its error out cluster. If no error has occurred, then this VI executes normally and sets its own corresponding error message. Using error in and error out clusters is a convenient way to check errors and to specify execution order by wiring the error output from one subVI to the error input of the next.
Get value returns the actual attribute value.
error out is a cluster that describes the error status after this VI executes. If an error occurred before this VI was called, error out is the same as error in. Otherwise, error out shows the error, if any, that occurred in this VI. Use the error handler VIs to look up the error code and to display the corresponding error message. Using error in and error out clusters is a convenient way to check errors and to specify execution order by wiring the error output from one subVI to the error input of the next.
