InvisibleApp.OnDataChangeDelay Property

  • Article
Visio Automation Reference

Gets or sets how long the Microsoft Office Visio instance waits before advising a container application that a Visio document being shown by the container has changed and should be redisplayed. Read/write.

Version Information
 Version Added:  Visio 3.0

Syntax

expression.OnDataChangeDelay

expression   An expression that returns a InvisibleApp object.

Return Value
Long

Remarks

The OnDataChangeDelay property affects only instances of Visio that are run from within an OLE container document.

  • Setting the value of the OnDataChangeDelay property to zero (0) causes Visio to send immediate advises to the container as data changes in open Visio documents.
  • Setting the value of the OnDataChangeDelay property to -1 causes Visio to use the interval specified in the OLEUpdateDelay entry in the registry. If the registry doesn't contain this setting, Visio defaults to using a value of 10,000 (milliseconds).
  • Setting the OnDataChangeDelay property to any value other than -1 or 0 overrides the registry setting and sets the delay between advises to the value of OnDataChangeDelay. If the OnDataChangeDelay property is not set or set to 1 and the OLEUpdateDelay setting is 0, Visio never sends advises to the container.

If you experience decreased performance when you add or move shapes that are contained in a Visio 2003 drawing that is hosted in the Visio 2003 ActiveX Control, you can install a hot fix and then use the OnDataChangeDelay property to overcome this problem.
