SendKeepAlive Method
Sends a keep-alive message.
Syntax
bool SendKeepAlive();
Remarks
Use this method to send a keep-alive 'ping' to the server. The response, if it comes back, will be reported via the KeepAliveResponse event.
Keep-alive messages provide good means for keeping the connection alive and stay immune to timeouts.
Error Handling
This method returns a Boolean 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.
