SCardTransmit problem

I'm trying to write a little test app to communicate with a smart card (using a GempPC Twin reader). program runs successfully until SCardTransmit function (SCardEstablishContext, SCardListReaders and SCardConnect functions return SCARD_S_SUCCESS and my card handle is 0xEA010000). this function returns 14 and does not execute.
this value is not in the "Smart Card Return Values" list in the msdn and therefor i do not have any idea for solve this problem. plealse helpe me.
my source code:
CString strReaderName ;
DWORD dwResult ;
DWORD dwReaderNameLen ;
DWORD dwProtocol;
LPSTR szListReaders = NULL;
LPTSTR szSCReader = NULL;
BYTE ATR[30] ;
DWORD ATRLen,dwState ;
byte command[] = { 0x80, 0xA4, 0x00, 0x00, 0x02, 0xFF, 0x02 };
BYTE pbRecvBuffer[500] ;
DWORD pcbRecvLength ;

dwResult=SCardEstablishContext(SCARD_SCOPE_SYSTEM,NULL,NULL,&m_hContext) ;
if(dwResult!=SCARD_S_SUCCESS)
{
AnalizeResult(dwResult);// selects a value from "Smart Card Return Values"
return ;
}
dwResult=SCardListReaders(m_hContext,NULL,NULL,&dwReaderNameLen);
if(dwResult != SCARD_S_SUCCESS)
{
AnalizeResult(dwResult);// selects a value from "Smart Card Return Values"
return;
}
szListReaders = (char*) malloc(dwReaderNameLen);
dwResult = SCardListReaders(m_hContext,NULL,(LPTSTR)szListReaders,&dwReaderNameLen);
if (dwResult != SCARD_S_SUCCESS)
{
AnalizeResult(dwResult);// selects a value from "Smart Card Return Values"
return;
}
szSCReader = (LPTSTR) szListReaders;
if(!szSCReader || *(szSCReader) =='\0')
{
if(szListReaders) free(szListReaders);
dwResult = SCardReleaseContext(m_hContext);
MessageBox("No readers present!");
return;
}
dwResult=SCardConnect(m_hContext,szSCReader,SCARD_SHARE_SHARED,SCARD_PROTOCOL_T0,&m_hCard,&dwProtocol) ;
if(dwResult!=SCARD_S_SUCCESS)
{
AnalizeResult(dwResult); // selects a value from "Smart Card Return Values"
return ;
}
dwResult=SCardStatus(m_hCard,(LPTSTR)szListReaders,&dwReaderNameLen,&dwState,&dwProtocol,ATR,&ATRLen) ;
if(dwResult!=SCARD_S_SUCCESS)
{
AnalizeResult(dwResult); // selects a value from "Smart Card Return Values"
return ;
}
MessageBox(szSCReader) ;
switch ( dwState )
{
case SCARD_ABSENT:
MessageBox("Card absent.");
break;
case SCARD_PRESENT:
MessageBox("Card present.");
break;
case SCARD_SWALLOWED:
MessageBox("Card swallowed.");
break;
case SCARD_POWERED:
MessageBox("Card has power.");
break;
case SCARD_NEGOTIABLE:
MessageBox("Card reset and waiting PTS negotiation.");
break;
case SCARD_SPECIFIC:
MessageBox("Card has specific communication protocols set.");
break;
default:
MessageBox("Unknown or unexpected card state.");
break;
}
dwResult=SCardTransmit(m_hCard,SCARD_PCI_T0,command,7,&pioRecvPci,pbRecvBuffer,&pcbRecvLength) ;
if(dwResult!=SCARD_S_SUCCESS)
{
AnalizeResult(dwResult); // selects a value from "Smart Card Return Values"
return ;
}

I use a SCARD_IO_REQUEST structure, this way has been working fine for many year ...

SCARD_IO_REQUEST        pio;

if(enScProt_T0 == m_ActiveProtocol)
{   pio.dwProtocol = SCARD_PROTOCOL_T0; }
else if(enScProt_T1 == m_ActiveProtocol)
{   pio.dwProtocol = SCARD_PROTOCOL_T1; }

pio.cbPciLength = sizeof(SCARD_IO_REQUEST);

m_lErrCode = SCardTransmit(m_hScConnect, &pio, pBufTx, LenTx, &pio, pBufRx, &LenRx);
if(SCARD_S_SUCCESS != m_lErrCode) {
    CString sT;
    sT.Format("Error SCardTransmit (0x%08X). ", m_lErrCode);
    m_pDlg->PutMsg(sT, true);
    return false;
}

LOGFONT.lfFaceName is declared as TCHAR. TCHAR will work according to your application that is, i think you don't have _UNICODE defined in your application.
If so TCHAR will act as char, wcscpy will expecting WCHAR but you passing char. normal strcpy(..) or _tcscpy(..)
Try this... hope it'll work...

See strcpy(m_lf.lfFaceName, "Times New Roman");for your answer

and see maybe its some helpful to you

<br />
	LOGFONT			m_lf;<br />
	NONCLIENTMETRICS nm;<br />
	nm.cbSize = sizeof (NONCLIENTMETRICS);<br />
	ZeroMemory ((PVOID) &m_lf,sizeof (LOGFONT));<br />
<br />
	SystemParametersInfo(SPI_GETNONCLIENTMETRICS,nm.cbSize,&nm,0); <br />
		m_lf =  nm.lfMenuFont;<br />

Any icons for window app ?

17-Jul-06 0:58

See

<code>
	m_Tool.Create(this);
	m_Tool.AddTool(GetDlgItem(IDC_BUTTON1),"Is this a test");
	m_Tool.Activate(true);



BOOL CAnswerDlg::PreTranslateMessage(MSG* pMsg) 
{
   if (m_Tool)            
      m_Tool.RelayEvent(pMsg);
   
   return CDialog::PreTranslateMessage(pMsg);
}

Hi,

I try to source for icons for programming window applications in
google, but the results are noisy and I just find one or two
icon suites. Anyone knows any good websites for software icons ?

Thanks

Search for iconizer. And preferably ask it such things in the lounge or even soapbox. This is the c++ programming message board.

Hi i saw you asking code for all the questions.
And many people told you to have a look at MSDN first.
After getting the API you need, check its parameter and the way how it can be used in MSDN.
Refer here[^]

Do you know, Why all the people want you to search MSDN ?

Its simple, then only you can learn MFC and also other persons help won't work all the time.

If you search by yourself it won't forget and you may come across various other API and techniques. It might not be the thing u want, but it'll be helpful in the future and to know MFC.

If you depend on other persons, you can make your thing to work but u will forget it as quickly as possible and you'll not know the working technique behind it.

'www.msdn.microsoft.com' is the msdn site and use the search facility in it.
