WriteToSocketEx - method of the PmaData object
Syntax:
Boolean WriteToSocketEx(Long nType, Long nSubType, Long nFrom, Long nCount)
Parameters:
| 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 |
|---|
Return value:
true - The method successfully
queued the request for sending data to the server. After data transfer the
onEndOfTransfer event is triggered.
false - 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.
Note:
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 and
nCount parameters can depend on the
nType and
nSubType parameters.
Supported subtypes of the protocol:
| nType |
nSubType |
meaning |
| 0 |
0 |
protocol for transmission of the whole PmaData object. Parameters nFrom and nCount are ignored. |
| 1 |
1 |
this allows to enter by the nFrom and nCount parameters from which value and how many values of the object have to be sent |

JavaScriptVBScriptSelect and copy to clipboard
var oData = pMe.Pm("/Data");
oData.WriteToSocketEx(1, 1, 0, 3);
// or
var bDone = oData.WriteToSocketEx(1, 1, 0, 3);
// bDone = true or false
Dim oData
Set oData = pMe.Pm("/Data")
oData.WriteToSocketEx 1, 1, 0, 3
' or
Dim bDone
bDone = oData.WriteToSocketEx(1, 1, 0, 3)
' bDone = true or false
