Configuring the Properties of Several VIs At Once

The following instructions apply to LabVIEW 5.1.x and later. Use the Edit Multiple VI Setups example VI to select a list of VIs and configure VI properties on the entire list at once. The example is located in the labview\examples\viserver\mltsetup.llb.

You can use the Edit Multiple VI Setups example VI to programmatically change properties of several VIs at once, and save these changes to disk. When developing an application, you may want to configure your VIs to allow debugging and run-time shortcut menus, make scrollbars visible, and allow windows to be resized. However, when you distribute your application, you may want to disable these features and ensure that specified other properties are set and queried. You can use VI Server to write applications that programmatically edit VIs instead of going through the VI Properties dialog boxes for each VI.

You can modify the Edit Multiple VI Setups example VI to remove the block diagrams from several VIs or LLB files at the same time. The needed files are saved to the Save Setups VI.

Note: This example modifies the VI properties of every referenced VI, causing them all to contain the same properties. If you do not want to modify these properties, delete the Property Node in the Save Setups VI.

Warning: Removing the block diagrams is permanent. Save master copies of the VIs that include the diagrams to a read-only location before removing the block diagrams.

In LabVIEW 6.x, the example uses Property Nodes instead of Attribute Nodes, although some of the labels indicate otherwise.
