Feb 18, 2011We have been downloading Office 2003 documents stored in our database as images successfully using our ASP.NET 2.0 web portals. We recently started storing Office 2007 documents and though they upload without issue, the download and render does not work. The file opens with the error - "The file is corrupt and cannot be opened". It is only with Office 2007 files we see this. The web server supports the Office 2007 MIME types. We also apply the correct content-type when uploading a file to the database. Sample BinaryWrite code below. Is there something I am overlooking unique to Office 2007 files?

View 7 RepliesC# - Download Image Using Javascript / JQuery?
Jan 28, 2010We are using asp.net and c#3.5 implementing a website using quite a lot of jQuery. We would like to download an img from the browser window, but (and here's the trick) in a button click (in addition to right click save as)...
Before we get into it, I should state that we know that this is an img tag and from the front end, we can easily download the image using right click save as. The only reason we wish to download the image from a (say) button click is because across the site we have download buttons for downloadable content (like datatable to excel files and pdfs, etc) and we would preferably like to keep the standard across thewebsite.
We are producing graphs using Microsoft Chart Control which renders the graphs to the screen pretty well. This renders an image to the screen as shown below in an example (using Firebug)
<div align="center" style="margin-top: 30px; margin-bottom: 30px;" id="graph">
<img style="border-width: 0px; height: 500px; width: 465px;" alt="Chart Loading" src="/Telma.UI/ChartImg.axd?i=chart_194e3c04c11240a7b7fba3e3e1d76d39_2.jpeg&g=338b984aaab84b1da9a63db3150211e2" borderdashstyle="Solid" id="ctl00_Chart1">
</div>
The img tag is generated from the Chart Control which in the asp is in an <asp:Chart> tag.
Now as an important side note we have in the web.config
<add key="ChartImageHandler" value="storage=session;privateImages=true;timeout=10;deleteAfterServicing=false;WebDevServerUseConfigSettings=true;" />
There is a known bug with MS Chart Control that if you store the image in session variables or memory, that the image is only accessible once and not persisted. Described here
We don't have a physical location for the image when it is created (and most often the Chart Control destorys the image).
What we need is some client side method of downloading this image content from the screen as it is rendered, but without having access to the physical image at the back end. We do not want to use the chart control property:
ImageStorageMode="UseImageLocation"
