Syntax

Sub ControlName_IMAQWarning(StatusCode, ContextID, ContextDescription)

Applies To

CWIMAQ

Purpose

Fires when an NI-IMAQ warning occurs.

Remarks

You can write a global warning handler for the CWIMAQ control in the event handler for IMAQWarning. For example, you can compare the ContextID parameter to the CWIMAQErrorContexts constants in the event handler code to handle warnings only in certain contexts (configuring, reading data, and so on).

Parameters

StatusCode As Long

The status code for the warning.

ContextID As Long

Identifies the context of the warning. The CWIMAQErrorContexts constants define the possible values for this parameter.

ContextDescription As String

A textual description of the context.

Example

Private Sub CWIMAQ1_IMAQWarning(ByVal StatusCode As Long, ByVal ContextID As Long, ByVal ContextDescription As String)
    If ContextID = cwimaqAcquiring Then
        MsgBox ContextDescription & vbCrLf & CStr(StatusCode)
    End If
End Sub
