    ftp file size

    My question is...can this be fixed to work right??????????????????


    Code:
    int index;
             CString strText;
             index = m_dir.GetCurSel();
    
             m_dir.GetText(index,strText);
            
    
    	
    		 HINTERNET handle1 = FtpOpenFile(hIConnect,strText,GENERIC_READ,FTP_TRANSFER_TYPE_BINARY,0);
    		DWORD filesized =  FtpGetFileSize(handle1,NULL);
    		CString csNumber;
    csNumber.Format("%lu", filesized);
    
    MessageBox(csNumber,csNumber,MB_OK);
    HANDLE hFile    = CreateFile(strText, GENERIC_WRITE, NULL, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);
    char Buffer[4024];
      DWORD dwRead =0;
     
      
    
    
    m_yay.SetRange(0,filesized);
      while(InternetReadFile(handle1, Buffer, sizeof(Buffer), &dwRead) == TRUE)
      {
        if ( dwRead == 0) 
          break;
        DWORD dwWrite = 0;
    	progress2 += dwRead;
    
    	m_yay.SetPos(progress2);
        WriteFile(hFile, Buffer, dwRead, &dwWrite, NULL);
      }
    that code above is for a FTP CLIENT using WININET. the code is getting a file from the server and downloading...it works, but the progress bar is not working right....like it fills to fast...sometimes it doesn't even move...so can you help me with this problem

    Re: ftp file size

    MY question is....why does the progress bar go crazy..filling like 10000 times..instead of starting from the beginning and slowing incrementing ot the end....

    I used StepIt instead of setpos and its almost working...
    [code]


    the progress bar goes crazy..it goes all the way about 1 million times....

    Re: ftp file size

    m_yay.SetRange(0,filesized);
    Please read carefully about PBM_SETRANGE message

    Re: ftp file size

    alright.. I fixed
    Code:
     m_yay.SetRange(0,100);
    And also..here isi the code that I edited..but still the progress is going crazy. Should I put the "StepIt" function in a while loop? Or maybe chop it up and put it in a FOR LOOP?
    Code:
    while(InternetReadFile(handle1, Buffer, sizeof(Buffer), &dwRead) == TRUE)
      {
        if ( dwRead == 0) 
        break;
        DWORD dwWrite = 0;
        WriteFile(hFile, Buffer, dwRead, &dwWrite, NULL);
    	m_yay.StepIt();
      }

    Code:
    while(InternetReadFile(handle1, Buffer, sizeof(Buffer), &dwRead) == TRUE)
      {
        if ( dwRead == 0) 
        break;
        DWORD dwWrite = 0;
        WriteFile(hFile, Buffer, dwRead, &dwWrite, NULL);
    	m_yay.StepIt();
      }
    Why do you use StepIt()? Did you call SetStep() before?

    Perhaps, you'll get back to reading MSDN documentation about CProgressCtrl and its methods?

    Re: ftp file size

    Well, probably it must be something like:
    Code:
      while(InternetReadFile(handle1, Buffer, sizeof(Buffer), &dwRead) == TRUE)
      {
        if ( dwRead == 0) 
          break;
        DWORD dwWrite = 0;
        progress2 += dwRead;
    
        UINT progressPercent = DOUBLE(progress2) * 100 / filesized + 0.5;
    
        m_yay.SetPos(progressPercent);
        WriteFile(hFile, Buffer, dwRead, &dwWrite, NULL);
      }
    Best regards,
    Igor

      DWORD dwRead =0;
     
      
    
    
    m_yay.SetRange(0,100);
      while(InternetReadFile(handle1, Buffer, sizeof(Buffer), &dwRead) == TRUE)
      {
        if ( dwRead == 0) 
          break;
        DWORD dwWrite = 0;

    	UpdateData(true);
    	CString what = m_what;
    	UpdateData(false);
    	DWORD dwNO;
    
    dwNO= atol((char*)(LPCTSTR)what);
    	UINT progressPercent = DOUBLE(progress2) * 100 / dwNO;
    
        m_yay.SetPos(progressPercent);
    
        WriteFile(hFile, Buffer, dwRead, &dwWrite, NULL);
