ReadFromSocket - method of object PmData
Reading data from the server group via Ethernet (TCP/IP) using the sockets.
ReadFromSocket As Boolean
- The method successfully queued
the request for reading data from the server. After data transfer the onEndOfTransfer
event will be fired.
- The method hasn't queued
the request for reading data. Probably the previous message about sending/receiving by sockets of this object hasn't been finished yet. The onEndOfTransfer
event is not fired.
The method only activates the data transfer but there is no assurance that data are already transferred after ending this method. The data transfer termination is announced by the onEndOfTransfer event.
Calling this method is meaningful only if the Sockets page is configured as the Socket client.
Variables on the Data page of this object are filled up by the incoming data.
