i want to port is open or close. example................ if (serial.Open(5,38400)) { MessageBox("Port 5 is open"); serial.Close(); } com 5 is network serial com port. VLINX ESP Server make virtual com port for my computer. when com5 is power on,i open com5(OK). when com5 is power off,i open com5(very slow my application)

i using serial Class for my vc++ project. i check sometime this port is on or off. (it more than one port) it may be 1 to 3 port. if port is close(power off),my project is slow. how can i control my project more faster. code here --------- // Serial.cpp #include "stdafx.h" #include "Serial.h" CSerial::CSerial() { memset( &m_OverlappedRead, 0, sizeof( OVERLAPPED ) ); memset( &m_OverlappedWrite, 0, sizeof( OVERLAPPED ) ); m_hIDComDev = NULL; m_bOpened = FALSE; } CSerial::~CSerial() { Close(); } BOOL CSerial::Open( int nPort, int nBaud ) { if( m_bOpened ) return( TRUE ); char szPort[15]; char szComParams[50]; DCB dcb; wsprintf( szPort, "COM%d", nPort ); m_hIDComDev = CreateFile( szPort, GENERIC_READ | GENERIC_WRITE, 0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL | FILE_FLAG_OVERLAPPED, NULL ); if( m_hIDComDev == NULL ) return( FALSE ); memset( &m_OverlappedRead, 0, sizeof( OVERLAPPED ) ); memset( &m_OverlappedWrite, 0, sizeof( OVERLAPPED ) ); COMMTIMEOUTS CommTimeOuts; CommTimeOuts.ReadIntervalTimeout = 0xFFFFFFFF; CommTimeOuts.ReadTotalTimeoutMultiplier = 0; CommTimeOuts.ReadTotalTimeoutConstant = 0; CommTimeOuts.WriteTotalTimeoutMultiplier = 0; CommTimeOuts.WriteTotalTimeoutConstant = 5000; SetCommTimeouts( m_hIDComDev, &CommTimeOuts ); wsprintf( szComParams, "COM%d:%d,n,8,1", nPort, nBaud ); m_OverlappedRead.hEvent = CreateEvent( NULL, TRUE, FALSE, NULL ); m_OverlappedWrite.hEvent = CreateEvent( NULL, TRUE, FALSE, NULL ); dcb.DCBlength = sizeof( DCB ); GetCommState( m_hIDComDev, &dcb ); dcb.BaudRate = nBaud; dcb.ByteSize = 8; unsigned char ucSet; ucSet = (unsigned char) ( ( FC_RTSCTS & FC_DTRDSR ) != 0 ); ucSet = (unsigned char) ( ( FC_RTSCTS & FC_RTSCTS ) != 0 ); ucSet = (unsigned char) ( ( FC_RTSCTS & FC_XONXOFF ) != 0 ); if( !SetCommState( m_hIDComDev, &dcb ) || !SetupComm( m_hIDComDev, 10000, 10000 ) || m_OverlappedRead.hEvent == NULL || m_OverlappedWrite.hEvent == NULL ){ DWORD dwError = GetLastError(); if( m_OverlappedRead.hEvent != NULL ) CloseHandle( m_OverlappedRead.hEvent ); if( m_OverlappedWrite.hEvent != NULL ) CloseHandle( m_OverlappedWrite.hEvent ); CloseHandle( m_hIDComDev ); return( FALSE ); } m_bOpened = TRUE; return( m_bOpened ); } BOOL CSerial::Close( void ) { if( !m_bOpened || m_hIDComDev == NULL ) return( TRUE ); if( m_OverlappedRead.hEvent != NULL ) CloseHandle( m_OverlappedRead.hEvent ); if( m_OverlappedWrite.hE

can i pass CStringArray from dll. example... CStringArray my(void) { CStringArray a; --- a.Add("a"); a.Add("b"); a.Add("c"); a.Add("d"); -- return a; } i can not pass CStringArray from dll. error C2558: class 'CStringArray' : no copy constructor available i don't know. how can i control CStringArray in dll?

can u tell me about heap..(memory allocate) i'm just small programmer. so,i can't handle. how can i keep?

my code here---------> test.h ------ TEST_API void TestCStringArray(CStringArray* _testarray); test.cpp -------- TEST_API void TestCStringArray(CStringArray* _testarray) { _testarray->Add("test1"); _testarray->Add("test2"); _testarray->Add("test3"); _testarray->Add("test4"); } ============================================================ using dll code here------> typedef void (*EXTERNAL_TESTCSTRINGARRAY) (CStringArray* _testarray); EXTERNAL_TESTCSTRINGARRAY dll_testcstringarray; CStringArray _testarray; dll_testcstringarray(&_testarray); for (int i=0;i<_testarray.GetSize();i++) { m_ist.AddString(_testarray.GetAt(i)); } what i missing? i don't know? how can i solve this error???

great! this work ... but i have problem.. i accepted result and then error appear... i don't know what happen..

"my application is dialog base application" and i using sample dll. i execute this application.. following error appear... i don't know this error type.

i can not pass CStringArray from dll.... my dll code here................... My.h ---- MY_API CStringArray MyName; MY_API void GetmyName(CStringArray _myname); My.cpp ------ MY_API void GetmyName(CStringArray _myname) { for(int i=0;i
