Hi friends,
I have one problem with Qextserialport , that i was unable to read and store the data to database properly.In my program i was able to read and store the data properly for some time only and after that the data was getting corrupted(ie overwriting in port I think).
Here I am receiving huge data from other system through RS232 in which it contains a data frame of 50 channels approximately ,each channel information occupies 2bytes.The data will be 50 data frames per 1sec.when I was reading and storing these channels data into database, channel wise.I am able to insert the data for 2 or 3seconds only and then after the data corrupted. for this i used QTimer to call "receiveMsg()" for every 1millisec.
But since i am new to threads i am still figuring out how to implement it in the program, Can you pls give me any suggestions on how i should implement threads in my program.I don't know how to create the new threads and own classes. I don't know how to implement the threads in my program . Where to declare and where to start the threads.
This is the code I tried with out Threads.

Qt Code: 
  1. void QT_receive::receiveMsg()
  2. {
  4. 	QByteArray msg ;
  5. 	QString ss;
  6. 	msg.clear();
  7. 	char buff[2];    
  8. 	if(port->bytesAvailable())
  9. 	{
  10. 		int i= port->read(buff, 2);
  11. 		msg = QByteArray::fromRawData(buff,2); 
  12. 		if (i!= -1)
  13. 			buff[i] = '\0';
  14. 		else
  15. 			buff[0] = '\0';
  16. 		int d = 0;
  17. 		while(d<msg.count())
  18. 		{
  19. 			m.prepend(msg.at(d));
  20. 			d++;
  21. 		}
  22. 		ss = m.toHex();
  23. 		QString sq("INSERT INTO Bulkdb values(%1,%2)");
  24. 		sq = sq.arg(rcount)
  25. 		.arg("'"+ ss +"'");
  26. 		m_query.exec(sq);
  27. 		rcount++;
  28. 		ss.clear();
  29. 		m.clear();  
  30. 		}  
  31.     }
