Hi,

For some reason, when checking the physical memory in task manager when the thread below is running, the memory keeps going down, I cannot understand why?

Qt Code: 
  1. void CanRead::run()
  2. {
  3. 	m_nCount = 0;
  4.  
  5. 	m_bCancelled = false;
  6. 	unsigned long nMsgAmount = 2;
  7.  
  8. 	CANDATA can[MAX];
  9.  
  10.  
  11. 	while( !m_bCancelled )
  12. 	{
  13.  
  14. 		unsigned long numMsgs = 0;
  15. 		PASSTHRU_MSG *pRxMsg = NULL;
  16. 		pRxMsg = theApp->GetMessageDetail( &numMsgs, 0 );
  17. 		nMsgAmount = numMsgs;  // store amount of messages we got
  18. 		int index = 0;
  19. 		// Read can data, store in buffer ( read say N amount and then emit? )
  20. 		while ( numMsgs && !m_bCancelled )
  21. 		{
  22. 			QString szTemp = "";
  23. 			can[index].strData = "";
  24. 			unsigned int iCanId = 0;
  25. 			for ( int iLoop = 0; iLoop < 4; iLoop++)
  26. 			{
  27. 				iCanId = (iCanId << 8 ) | pRxMsg->Data[iLoop];
  28. 			}
  29. 			if( pRxMsg->RxStatus & 0x100 )
  30. 				can[index].strId.sprintf( "%X X", iCanId);
  31. 			else
  32. 				can[index].strId.sprintf( "%03X", iCanId);
  33.  
  34. 			for ( int iLoop = 4; (unsigned)iLoop < (pRxMsg->DataSize ); iLoop++)
  35. 			{
  36. 				szTemp.sprintf("%02X ", pRxMsg->Data[iLoop]);
  37. 				can[index].strData += szTemp;
  38. 			}
  39.  
  40. 			can[index].strTime.sprintf("%04d", pRxMsg->Timestamp);
  41.  
  42. 			numMsgs--;
  43.  
  44. 			m_nCount++;
  45.  
  46. 		}  // end while ( ulNoMsgs )
  47.  
  48.  
  49. 		msleep(1);
  50.  
  51. 	} // end while ( true )
  52.  
  53. }

I thought it might have been the call to GetMessageDetail, but commenting this out and the memory still leaks?

Anyone any ideas?

Kind regards,
