expression.BeginConnect(ConnectedShape, ConnectionSite)
expression Required. An expression that returns one of the objects in the Applies To list.
ConnectedShape Required Shape object. The shape to which Microsoft Publisher attaches the beginning of the connector. The specified Shape object must be in the same Shapes collection as the connector.
ConnectionSite Required Long. 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. Connection sites are numbered starting from the top of the specified shape and moving counterclockwise around the 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.
Remarks
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.
When you attach a connector to an object, the size and position of the connector are automatically adjusted if necessary.
Use the EndConnect method to attach the end of the connector to a shape.
Example
This example adds two rectangles to the first page in the active publication and connects them with a curved connector. Note that the RerouteConnections method overrides the values you supply for the ConnectionSite arguments used with the BeginConnect and EndConnect methods.
Dim shpRect1 As Shape
Dim shpRect2 As Shape
With ActiveDocument.Pages(1).Shapes
' Add two new rectangles.
Set shpRect1 = .AddShape(Type:=msoShapeRectangle, _
Left:=100, Top:=50, Width:=200, Height:=100)
Set shpRect2 = .AddShape(Type:=msoShapeRectangle, _
Left:=300, Top:=300, Width:=200, Height:=100)
' Add a new curved connector.
With .AddConnector(Type:=msoConnectorCurve, _
BeginX:=0, BeginY:=0, EndX:=100, EndY:=100) _
.ConnectorFormat
' Connect the new connector to the two rectangles.
.BeginConnect ConnectedShape:=shpRect1, ConnectionSite:=1
.EndConnect ConnectedShape:=shpRect2, ConnectionSite:=1
' Reroute the connector to create the shortest path.
