InvisibleApp.OnDataChangeDelay property (Visio)

  • Article

Gets or sets how long the Microsoft 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.

Syntax

expression.OnDataChangeDelay

expression An expression that returns an 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.

Note

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