Cannot download the file

Hello

I m using method below to download the file, but it is with size 0KB downloading. (debugger is not going inside the while() loop)

' Public Sub fileDownload (FacesContext facesContext, OutputStream, outputStream)

{

Add the code in the event here...

Try

{

String filePath = "D:\\UploadTest\\abc.png";

= New File (filePath);

System.out.println ("file length..." + file.length ()); showing 0

If (file.exists ())

{

Byte [] buf = new byte [1024];

InputStream is = new FileInputStream (file);

content int = 0;

While ((contenu = is.read (buf, 0, buf.length)) > 0)

{

outputStream.write (buf, 0, content);

outputStream.flush ();

}

outputStream.flush ();

outputStream.close ();

is. Close();

}

catch (System.Exception e)

{

e.printStackTrace ();

}

No need for anything try this code;

  public void fileDownload(FacesContext facesContext, java.io.OutputStream outputStream) throws IOException
  {
    try
    {
      String filePath = "D:\\UploadTest\\abc.png";
      File file = new File(filePath);
      byte[] b = new byte[(int) file.length()];
      FileInputStream fileInputStream = new FileInputStream(file);
      fileInputStream.read(b);
      outputStream.write(b);
      outputStream.flush();
    }
    catch (IOException ioe)

Error: Windows Media Player cannot play the file. The player can not support the Codec that was used to compress the file, MP3 downloads will not play

Original title: MP3 downloads don't play no not on WMP

My Windows Media Player recently stopped playing downloads from Amazon. I've never had this problem before. I installed VLC Player, has not worked... off the WMP in the Windows app, restarted, turned on the back and restarted... did not help. I get the message "Windows Media Player cannot play the file. The player may not support the Codec used to compress the file. This is for multiple downloads, so I don't think they would be all corrupted files.

Hello

Have you done any software or changes to the material on the computer before this problem?

You mentioned that the files do not play on a third-party player as well. I suggest you to check if the files are corrupt.

Windows Media Player cannot play the file. The player might not support the file type or does not support the codec used to compress the file. (((PLEASE HELP)))

I understand that this has been a matter of repetition and I made the suggestions listed and nothing works. This just started happening, although downloading songs, and once they are finished I'm not able to play them with Windows Media Player. The initial message indicates that the file has an extension that is not recognized by Windows Media Player.

I have a Dell Inspiron Laptop with Windows Vista Home. Any suggestions? What should I chahnge how I download and save music?

Hey Taylor09,

You may find that you are getting this message in Windows Media Player due to one of the following reasons.

a. you try to play a file that is not supported by the player.

b. you are trying to play a file that the player does not support, but the file was compressed by using a codec that is not supported by the player.

Step 1:

Confirm that you are trying to play a supported file type. The following article lists the types of files (formats) supported by Windows Media Player.

Information on the types of media files that supports Windows Media Player

Note that if you tried to play the file type is included in this table, the file might have been encoded with a codec that is not supported by Windows Media Player. If this is the case, Windows Media Player cannot play the file.

Step 2:

Download the necessary codec to play the file.

Audio service does not not after download of Creative, restarts, error 0 x 80070002, the system cannot find the file specified

Yesterday, I downloaded and installed updated Creative to my its Soundblaster card from Windows Update. It lead me to a large download of Creative for its console related sound and SW, and things worked fine. When I restarted this morning, there was a horrible loud hum while Windows was loading, and I made a hard stop. When I rebooted, the buzz was gone, but the icon in the status bar indicates that the sound was off. The sound message indicates that the audio service is not running. I tried to restart the computer several times, but the results were the same. I tried to restart the audio service of the Task Manager, but got an error message 0 x 80070002, the system cannot find the file specified. Where should I go from here?

3. click on the levels tab.
4. move the cursor upwards or downwards to set the desired volume level, and then click OK.

Method 2: use Control Panel

2. click on the tab playback or recording .
3. double click the device for which you want to set the parameters. For example, double-click on Microphone.

Q10 blackBerry download full - cannot open the file

My previous Blackberry Curve 8330 (using version 4.0 of the software), I had an eSecure app that I downloaded from a text message sent to my phone. With my new Q10, I "ve done to transfer the data from my old phone again, but the apps has not been transferred. All lists of contacts, emails, etc. worked well.

I logged on the site where I can go to request a new message text for the app, but the OS Q10 is not an option, the highest available Blackberry version is 7.0. When I select 7.0 and receive this new text message on my phone, I open it and the link download, but when I click on the downloaded file I get a popup message that says: "Cannot open the file."

Please notify

Applications BlackBerry OS7 (and OS4) do not work on OS10. OS7 (and the previous operating system) is based on Java, OS10 is completely different (QNX based). So if the seller does not level its app to OS10, there is nothing you can do.

Hi Ron,

In your efforts, you mention in step #6 you save the file as a PDF secure. Applied security files cannot be previewed to the customer, that's why you get the message "cannot preview filetype please download the file for display. This message preview complete and preview the hover. After downloading the file, you should be able to access it without error (within the limits of the guarantee applied).

The hover behavior you report is expected. If you hover over a file name, you will see "hover" noticed after a few seconds, that will get you a small preview of the file (rather than having to open it in the overview). If poster only if you hover over a name of file, not in the empty area of each line, so that you have not seen continually arise.

Hope this helps,

Photosmart C4780 installation fails at the "system cannot find the file specified."

My problem began simply with your printer, a HP Photosmart C4780, who has always had a wireless connection and would not print. Initially, the checked network connection fine control panel of the printer. I ran a Microsoft printer troubleshooting, which found a block in line print and authorized. The first test page print, but did print the "internal test page. I did not understand what it meant, so I looked for help on the HP site.

I ran the HP print and Scan Doctorand he suggested I have reinstall the driver. I have downloaded and saved the current HP (PS_AIO_06_C4700_USW_Full_Win_enu_140_175.exe) and then uninstalled the existing driver. When I tried to install a new, a window pops up saying "the system cannot find the file specified," with only a single box for click that simply says "OK". The installation went through 'examining installation options', after entering "check updates, download updates, install updates" and then it was all in "audit system", who jumped out of the window "file not found" upwards, and when I clicked 'OK', the installation window as well as the error message box simply disappeared. Which I suppose is the path to the file is under the window, but it didn't fit so he showed not the end. What I read was "C:\Users\... \Local\Temp\7zS588E\Setup\.\Setup\hpzpnp40...»

I found a topic on the same printer model for the same problem in the forum, which offered this hotfix:

You must first complete a level 3 of the software uninstallation. I've included the steps below to do this.

1. press the Windows key and the letter R
2. type %temp%, and then click OK
3. open the 7z folder (a more recent if there are multiples)
4 open the util folder
5 open the folder of the ccc
6. double-click on the Uninstall_L3

Once you have completed the Uninstall_L3, delete all of the items listed in the temp folder. Note, you will not be able to remove all the elements, please ignore those that do not. Then please empty the trash and perform a clean boot. I've included the document «How to perform a boot in Windows» If your computer does not request it, restart your computer.

Once your computer is back, you must reinstall the printer software. You can do this either by using the Setup CD, or by downloading the software.

I did what was suggested, until he got to the point where it says it was the case recommend not removing any more items if I had intended on using the HP Officejet printer (Yes, I have a second HP printer connected to the network) anytime in the future. Not really understand how it all works, I decided to stop what I was doing, so unfortunately it has not solved my problem.

Do I need to uninstall both printers HP before I can reinstall a? And if I do that, is there a reason that I wouldn't be able to reinstall the two printers? Looks like I'm asking trouble. Bottom line... I can not install the driver.

I tried to install the full versions and the driver base and still get the same result.

I have a HP Pavilion dv6 - 3100t for computer laptop, running Windows 7 Edition Premium, version 6.1.7601 family service pack 1 64-bit. I have not installed new hardware or software. This printer has always had a wireless connection. The router I'm using is a Netgear 54Mbps WGR614 v6 (provided by my cable company) and the network includes not only my laptop and the Photosmart printer, but also desktop ASUS, HP printer, an Officejet 6300 series (used only for printing graphics and photos via a wired to the router) and a chip on Vizio TV. I use Norton 360 first Edition and disabled the antivirus auto-protect when I downloaded and tried to install the driver.

Help, please! And thanks in advance for your time and your attention.

Oh, Jamieson, it worked! I can print again! A massive amount of thanks and congratulations to you.

I couldn't believe it when he actually passed the point where it normally would stop the installation, but then almost at the end, upward jumped «Fatal error during installation» My excitement sank into a depression. He said while the installation was not successful and he needed to collect information in order to diagnose the fault. I looked at what has been collected, and it was more or less gobblety-* beep * for me. There was a code of 19714722 error condition, if that means anything.

Then he placed on my desk, the "Error of Installation HP - Windows 7.hta" file and instructed me to do away with the current window, restart, and then open the file and move forward with these guidelines. I did and he basically had me to restart the computer once again, and then turn the printer off, unplug the printer, then unplug the router, wait 30 seconds and then plug the TAA - DAA and back in, I'm back in the business of printing.

Thank you very much for your time and patience.

All the best to you and yours!
