SendCommand Method

Will format and send a PDU using the specified command identifier and payload.

Syntax

QByteArray SendCommand(int iCommandId, const QByteArray& qbaPayload);

Remarks

This method offers a way to do more with the class than is directly supported. This method takes a command identifier and a payload, which includes every required and optional field after the header, and will create the 16-byte header for it before sending it to the server. The response PDU is returned both in the PITrail and by this method.

Error Handling

This method returns a Binary String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
