Re: Problem displaying data in a Editbox

I have attached my callback function and com select dialog function
for the main dialogue. This is just a rip off from the serial MFC
demo. I have added a breakpoint and it does get into this function. I
have added a watch on szData and it does store the whole string from
the embedded board but when I try to display on an edit box or a rich
edit box it does not display the full string. I have also tested the
setWindowtext function by printing a text and that works fine. I have
also use unicode in my project option as the serial MFC demo also use
unicode settings but I still experience the same problem. The serial
class MFC demo from Codeproject works fine as it display the captured
string continuously.

LRESULT CMyTabExampleDlg::OnSerialMsg (WPARAM wParam, LPARAM /
*lParam*/)
{

    CSerial::EEvent eEvent = CSerial::EEvent(LOWORD(wParam));
    CSerial::EError eError = CSerial::EError(HIWORD(wParam));

    if (eEvent & CSerial::EEventRecv)
    {
        // Create a clean buffer
        DWORD dwRead;
        char szData[101];
        const int nBuflen = sizeof(szData)-1;

        // Obtain the data from the serial port
        do
        {
            m_serial.Read(szData,nBuflen,&dwRead);
            szData[dwRead] = '\0';

            // Scan the string for unwanted characters
            for (DWORD dwChar=0; dwChar<dwRead; dwChar++)
            {
                if (!isprint(szData[dwChar]) && !isspace(szData[dwChar]))
                {
                    szData[dwChar] = '.';
                }
            }

        } while (dwRead == nBuflen);

        m_disp_log.SetWindowTextA(szData);

    }
}

void CMyTabExampleDlg::OnComOpen()
{

    // TODO: Add your command handler code here
    // Obtain the requested COM port
    CComSelectDlg dlgComSelect(this);
    dlgComSelect.DoModal();

    // Open the serial port
    if (m_serial.Open(dlgComSelect.m_strComPort,this) != ERROR_SUCCESS)
    {
        AfxMessageBox(_T("Unable to open COM-port"),MB_ICONSTOP|MB_OK);
        GetParent()->PostMessage(WM_CLOSE);
    }

    m_serial.Setup
(CSerial::EBaud9600,CSerial::EData8,CSerial::EParNone,CSerial::EStop1);
