ThreadStartThreshold Property

Description

Gets or sets the amount of time (in milliseconds) a thread will spend generating an image representing a thumbnail item, before it should start an additional thread generating images representing thumbnail items.

Property type

Read-write property

Syntax

Visual Basic
Public Property ThreadStartThreshold As Long

Return Type

A long value which represents the amount of time a thread will spend generating an image for a thumbnail before it starts an additional thread.

Remarks

The default value is 3,000 milli-seconds.

The enforced value range will be 100 through 1/2 of the ThreadHungThreshold value.

A request for a thumbnail beyond the elapsed time threshold (in milliseconds) is considered "extended duration". If other thumbnails are requested, ThumbnailXpress adjusts for "extended duration" requests by starting additional thumbnail generation threads. If the additional threads also exceed the "Extended Duration" Threshold, the control continues to start new threads until the ThreadHungThreshold Property is reached.
