Articolo
09/13/2021

Returns the part of a shape from which a connection originates. Read-only.

Syntax

expression.FromPart

expression A variable that represents a Connect object.

Return value

Integer

Remarks

The following constants declared by the Microsoft Visio type library show return values for the FromPart property.

Constant	Value
visConnectFromError	-1
visFromNone	0
visLeftEdge	1
visCenterEdge	2
visRightEdge	3
visBottomEdge	4
visMiddleEdge	5
visTopEdge	6
visBeginX	7
visBeginY	8
visBegin	9
visEndX	10
visEndY	11
visEnd	12
visFromAngle	13
visFromPin	14
visControlPoint	100 + zero-based row index (for example, visControlPoint = 100 if the control point is in row 0; visControlPoint = 101 if the control point is in row 1)

Example

This Microsoft Visual Basic for Applications (VBA) macro shows how to extract connection information from a 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.
