Google doc no preview available error

Question

I used the google doc to display the pdf file in web broswer. It was working fine before. Now it gives no preview available. Most of the time it gives the blank screen with no preview available but sometime it opens the pdf. However i noticed that if the size of the pdf is small, it works fine but if the size is a bit larger with 10-100 or more pages, the no preview is shown.

WebBrowser view = new WebBrowser();
view.setURL("https://docs.google.com/gview?embedded=true&url=http://trafficpolice.gov.np/traffic/uploadfiles/56a0e8156d4ea.pdf");

WebBrowser view = new WebBrowser();

I added this code to my web.config. Works every time after these changes.

<basicHttpBinding>
    <binding maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" messageEncoding="Text">
      <readerQuotas maxDepth="2000000" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
    </binding>
  </basicHttpBinding>

Answer 5

For those who are trying localhost. You CANNOT use localhost to view previews. You can tunnel port 80 with ngrok and then it will work.

Answer 7

Several things that may cause this:

1. The browser you are using to upload these files.
2. The size of the file you are uploading.
3. Password/Permission of the files are set to private.

Quick Fix:

It has been noticed that most of the users who encounter this have been using Firefox (3.6.6 in particular). Try uploading your files using IE8 and clear your cache.
