    WinInet progress bar

    Will anyone help me out with a progress bar for a wininet ftp client?

    here is my code that I have so far but is not working.
    Code:
    int row = m_listcontrol.GetSelectionMark();
    
    CString s2 = m_listcontrol.GetItemText(row, 0); 
    UpdateData(true);
    CString pepsi = m_pep + "\\" + s2;
    UpdateData(false);
    
    HANDLE hFile = CreateFile(pepsi, GENERIC_READ, FILE_SHARE_READ, NULL,
            OPEN_EXISTING, 0, NULL);
    remote = FtpOpenFile(hIConnect,pepsi,GENERIC_WRITE,
     FTP_TRANSFER_TYPE_BINARY,0);
    BOOL bWriteSuccess = TRUE;
      DWORD progress = 0;
      DWORD maximum = GetFileSize(hFile, NULL);
      DWORD read = MAX_PATH;
      DWORD written = 0;
      
    char cSendBuffer[MAX_PATH];
    m_pro.SetRange(0,maximum/100000);
    while(progress < maximum && bWriteSuccess != FALSE)
     {
    
    	 ReadFile(hFile,cSendBuffer,256, &read, NULL);
     bWriteSuccess = InternetWriteFile(remote,cSendBuffer,read,&written);
     progress += written;
     m_pro.SetPos(progress/100000);
    here is a outline of the program....
    1. USER SELECTS FILE FROM LISTCONTROL
    2. PRESSES UPLOAD BUTTON and the progress is suppose to work


    can anyone help..maybe fix the code or give better tips

    Hi Vaas.

    Are you using a new thread for reading the file?

    Normaly, a thread is used to read the file and send message to the parent window to update the progress control.

    And, what is happend if file size is less than 100000??

    Best regards.

    To let us help maybe you give us some more details on what "is not working" looks like, in comparison to your expectations from the code execution.
    Best regards,
    Igor
