ToCell Property [Visio 2003 SDK Documentation]

Office 2003

Gets the cell to which a connection is made.

objRet = object.ToCell

objRet     The Cell object to which the connection is made.

object     Required. An expression that returns a Connect object.

Version added

2.0

Remarks

A connection is defined by a reference in a cell in the shape from which the connection originates to a cell in the shape to which the connection is made. The ToCellproperty returns the Cell object to which the connection is made.

Following is a list of possible connections and their related ToCell property values.

From the begin or end cell of a 1-D shape to...

• A connection point cell: The ToCell property returns the Connection.Xi cell.
• A cell of a guide or guide point: When the begin or end cell of a 1-D shape is glued to a cell of a guide or guide point, two connections are created—one from the endpoint's X cell to the guide's Angle cell, and the other from the endpoint's Y cell to the guide's Angle cell. The ToCell property of both Connectobjects returns the Angle cell.
• The pin of a 2-D shape (creates dynamic glue): The ToCell property returns the PinX cell.
• Any cell of a vertex row in a Geometry section: A new connection point is created and the ToCell property returns the Connections.Xi cell.
• The begin or end cell of a 1-D shape: A new connection point is created and the ToCell property returns the Connections.Xi cell.
• The edge (a cell in the Alignment section) of a 2-D shape: A new connection point is created and the ToCell property returns the Connections.Xi cell.

From the edge (a cell in the Alignment section) of a 2-D shape to acell of a guide or guide point: The ToCell property returns the Angle cell.

From an outward or inward/outward connection point cell of a 1-D shape to An inward or inward/outward connection point cell that is not a cell of a guide or guide point: When these cells are glued, two connections are created—one from the BeginX cell of the 1-D shape to the Connections.Xi cell, and the other from the EndX cell of the 1-D shape to the Connections.Yi cell. The ToCell property returns Connections.Xi for the first Connect object and Connections.Yi for the other.

From an outward or inward/outward connection point cell of a 2-D shape that is not a guide or guide point to an inward or inward/outward type connection point cell that is not a cell of a guide or guide point: If the outward connection point is directionless, the ToCell property returns the Connections.Xicell. If the outward connection point has a direction, two connection points are created. The ToCell property returns the Connections.Xi cell for both Connectobjects.

From a control handle to...

• A connection point cell: The ToCell property returns the Connections.Xi cell.
• A cell of a guide or guide point: When a control point is glued to a cell of a guide or guide point, two connections are created—one from the control point's X cell to the guide's PinX and the other from the control point's Y cell to the guide's PinY cell. The ToCell property of the first Connect object returns the guide's PinX cell and, for the second Connect object, the guide's PinY cell.
• Any cell of a vertex row in a Geometry section: A new connection point is created and the ToCell property returns the Connections.Xi cell.
• The begin or end cell of a 1-D shape: A new connection point is created and the ToCell property returns the Connections.Xi cell.
• The edge (a cell in the Alignment section) of a 2-D shape: A new connection point is created and the ToCell property returns the Connections.Xi cell.

Example

This Microsoft Visual Basic for Applications (VBA) macro shows how to extract connection information from a Microsoft Office Visio drawing. The example displays the connection information in the Immediate window.

This example assumes there is an active document that contains at least two connected shapes.
