Required Integer. A connection site on the shape specified by ConnectedShape. Must be an integer between 1 and the integer returned by the ConnectionSiteCount property of the specified shape. If you want the connector to automatically find the shortest path between the two shapes it connects, specify any valid integer for this argument and then use the RerouteConnections method after the connector is attached to shapes at both ends.
If there’s already a connection between the beginning of the connector and another shape, that connection is broken. If the beginning of the connector isn’t already positioned at the specified connecting site, this method moves the beginning of the connector to the connecting site and adjusts the size and position of the connector. Use the EndConnect method to attach the end of the connector to a shape.
When you attach a connector to an object, the size and position of the connector are automatically adjusted if necessary.
