Applies to:

DATAQSERIAL Active X Control

Description:

This function reports how many available new data points have been sent to the buffer since the last time data was retrieved using GetData. This property can be used instead of EventLevel which may be necessary with older programming languages (i.e., languages that do not respond to Active X events) by calling a subroutine when AvailableData reaches a certain value. This property is read-only.

Syntax:

variable=DataqSerial1.AvailableData

Variable:

Integer

Example:

Private Sub Start_Click()

DataqSerial1. EventLevel=20

DataqSerial1. Start

Label1.Caption = DataqSerial1.AvailableData

End Sub

Private Sub Stop_Click()

DataqSerial1. Stop

End Sub

Private Sub DataqSerial1_ NewData (ByVal Count As Integer)

DQChart1. Chart (DataqSerial1. GetData)

End Sub
