WriteToSocketEx - method of the PmaData object
Boolean WriteToSocketEx(Long nType, Long nSubType, Long nFrom, Long nCount)
|nType||(Long) Subtype of the data protocol|
|nSubType||(Long) Version of the data protocol subtype|
|nFrom||(Long) Index (zero-based index) of the variable in the PmaData object. From this variable (including) the data is sent|
|nCount||(Long) The number of variables in the object that are sent|
- The method successfully queued
the request for sending data to the server. After data transfer the onEndOfTransfer
event is triggered.
- The method hasn't queued
the request for sending data. Probably the previous message about sending/receiving by sockets of this object hasn't been finished yet. The onEndOfTransfer
event is not triggered.
This method is not functional for PmFree.
It allows the user to specify the subtype of the data protocol by which will communicate it with the server and for example the value and number of values of the object from which the data sent to the network will be read from the object. The exact meaning of the nFrom
parameters can depend on the nType
Supported subtypes of the protocol:
|nType ||nSubType ||meaning|
|0 ||0 ||protocol for the transfer of the whole PmaData object. Parameters nFrom and nCount are ignored.|
|1 ||1 ||this enables to enter by the nFrom and nCount parameters from which value and how many values of the object have to be sent|
var oData = pMe.Pm("/Data");
oData.WriteToSocketEx(1, 1, 0, 3);
var bDone = oData.WriteToSocketEx(1, 1, 0, 3); //bDone = true or false
