ToInt32 context. Save context. OutputStream, ImageFormat.

I extract the query string of the request to obtain the file name of the PDF document to convert, and the page to display. I then create an instance of the Pdf2Image class, and grab an image of the specified page. Next, you need to set the ContentType of the Response object so the web browser knows what to do with your content.

Finally, I save the image directly to the response's OutputStream. Make sure that the format you save the image as matches the content type you've specified. With these steps complete, building and running the website should present you with a pair of hyper links, and the first page of your PDF file as a static image. Open up the code behind file for Default. Specialized; using System. ParseQueryString pdfImage. Substring pdfImage. IndexOf "?

PageCount pdfImage. It also creates a new instance of the Pdf2Image class in order to obtain the number of pages in the document. If the new page number is in range, it updates the ImageUrl of the pdfImage causing the image handler to pull back the next page.

In Conclusion This sample is pretty inefficient and at the very least should be caching the images. I have the code in the "SelectedIndexChange" event of a gridview object. The code works the first time you click a link, but then no links or buttons or anything work on the page until I do a refresh F5.

Rick Strahl July 31, NET David - that can't be done and for good reason.

It'd be a huge security risk if files just started saving themselves automatically from the server. Jeff - I'd guess the problem is that you're writing a file out to disk and probably don't have permissions to do that. There's no reason for you to write to file first anyway. Just use Response. Write or Response. BinaryWrite to output your file content and it'll probably work.
