OnHistoryFull Event
Occurs each time a message is added to the History text box, when the total number of characters in the History text box is at least 90 percent of the MaxHistoryLength property (which is the maximum number of characters allowed in the History text box).
Syntax
object_OnHistoryFull(Percent)
Value Description object Required. An object expression that evaluates to a Chat control. Percent The exact percentage of the History text box's maximum length that has been used. Remarks
If the History text box gets too full to contain an incoming message, the top 20 percent of the text box's contents are removed. If this does not give enough space to fit the incoming message, more text is removed.
