Asp.Net Programming :: PDF Viewer Control


	PDF Viewer Control Does anyone know of an ASP.net control that will allow viewing a pdf file? Without streaming the file to the browser. I have to display a pdf without the pdf being stored on the web server and also not have the user prompted for a download. Thanks in advance, Rick If the information is not sent to the browser how will it work ? - Hide quoted text - "Rick" <rfem@newsgroups.nospam> wrote in message news:O%23mtTKtoHHA.4400@TK2MSFTNGP03.phx.gbl... > Does anyone know of an ASP.net control that will allow viewing a pdf file?

If you can't send it to the browser, how would you expect the viewer to see it. The easiest option is to stick it in an iframe - but they can still chose to set their browser to prompt for all files if thats what they want to have happen.

I know it has to display in a browser, but streaming directly to the browser forces the download prompt.And I'm not given the option from people higher up to make changes or force users to make the changes on the client side.

If you do have acrobat installed, but are still getting the download prompt, then the .pdf file extension probably isn't associated with acrobat on the windows OS you are using. Re-installing acrobat should fix this. You can also stream files using XMLHTTP, however, this will also require you to weaken security settings on your browser that would enable ADODB.scritping and the scripting.filesystemobject active X controls, opening you to internet attacks. I don't think there is a native ASP.NET control that ships with visual studio that allows you to view pdf files. -----------------------------------------------Reply----------------------------------------------- Hi Rick, For viewing PDF document in web page, it totally depend on the PDF viewer installed on client machine. So it is necessary to insure that the client has installed the PDF viewer software(unless you're using activex control for pdf viewing so that client need to download and install your activex component). Also, for whether client will prompt for open dialog, it depend on your client machine's explorer setting. You can configure it through the following steps: 1. open windows explorer 2. Tools ---> folder options---> File Types 3. choose the "PDF" extension and in the "Advanced" setting, you can find the "confirm open after download" checkbox option.

If your problem is that you don't want the user to wait for the entire file to download, then I have good news for you. The Adobe Reader browser plugin has a feature that allows you to stream the PDF page by page on demand. The users would only have to wait for the first page to load, and they could start navigating right away. This requires that you first optimize your PDF for the web, also known as linearization. Go to pdfzone.com and see if you can find a command line tool that converts an existing PDF file into a byte-servable linearized one. If you host that, Adobe Reader will fetch it page by page as the user is scrolling. Once again, this won't work unless you get a tool that linearizes the PDF first, or save it that way from Acrobat.
