ReadyToSend Property

Indicates whether the control is ready to send data.

Syntax

mqttcontrol.ReadyToSend

Default Value

False

Remarks

This property indicates that the underlying TCP/IP subsystem is ready to accept data. This is True after connecting to the remote host, and will become False if a call to PublishData or PublishMessage fails due to a WOULDBLOCK condition.

Once data can be sent again, the ReadyToSend event will fire and this property will be True.

If a WOULDBLOCK error occurs while sending a message the control will automatically complete the transmission when sending is possible. No action needs to be taken to re-send the message. ReadyToSend will fire after the control completes any partially sent messages.

This property is read-only and not available at design time.

Data Type

Boolean
