TraceOutput Property (Advanced)

Determines whether PortController emits trace information to the DefaultTraceListener.

Syntax

[Visual Basic]
object.TraceOutput [ = value ]

[C#]
object.TraceOutput [ = value ]

[C++]
object->TraceOutput [ = value ]

Parameters

object

An object expression that evaluates to a PortController object.

value

A boolean value indicating whether trace output is to be emitted.

Return Value

A boolean value indicating whether PortController is emitting trace output.

Default

False

Remarks

This property is intended to be used primarily as a debugging aid when working with tech support. Enabling trace output may have a noticable effect on application performance.

Errors

None

Example

[Visual Basic]
'Set TraceOutput
myPortController.TraceOutput = True

'Get TraceOutput
Dim TraceOutput As Boolean
TraceOutput = myPortController.TraceOutput


[C#]
// Set TraceOutput
myPortController.TraceOutput = true;

// Get TraceOutput
Boolean TraceOutput = myPortController.TraceOutput;


[C++]
// Set TraceOutput
myPortController->TraceOutput = true;

// Get TraceOutput
Boolean TraceOutput = myPortController->TraceOutput;
