Chart.Export creates zero byte GIF and hangs on server
[note: I posted this on excel.interopoledde, then noticed
that this group seems to be where all the action is. Sorry for the double post.] Doing Excel interop in C# ASP.Net. The following line works fine on several PCs, but not on the production environment: MyChart.Chart.Export(myFileName, null, null); This creates a GIF image of the chart, except on the server where a zero length GIF file is created and the ASP.Net app basically hangs up. Does anyone have any ideas why this straight forward piece of code would not work? One more piece of info... I am able to successfuly save the worksheet into the same folder on the web site. Thanks, AB |

Just a thought, could you export the chart locally, then copy it to the
server? - Jon ------- Jon Peltier, Microsoft Excel MVP http://www.geocities.com/jonpeltier/Excel/index.html _______ AB wrote: [note: I posted this on excel.interopoledde, then noticed that this group seems to be where all the action is.

Chart.Export creates zero byte GIF and hangs on server
Jon, thanks for replying.
At this point we have to do it on the web server. This problem is very bizzare. All of my interop code is working fine. Only the Chart.Export does not work. I did a work around where I call a macro in the sheet to export the chart. Now this work around works on the staging server, but get this... Neither approach works in production! In production all of the interop code works fine. But neither a call to Chart.Export or a Excel macro that does a Chart.Export will produce a GIF. And in the case of the production server, we don't even get a zero byte .GIF file. Any ideas?

It all sounds quite similar to the problem described here :

Thanks for the info Vic. Sure sounded like the same
problem but turns out it was something else! In case anyone is interested the problem was with the Office installation. The graphics filters were not installed on the web servers! -----Original Message----- It all sounds quite similar to the problem described here : http://www.google.com.au/groups?hl=en&lr=&ie=UTF- 8&threadm=utq4Z78oDHA.1724% 40TK2MSFTNGP10.phx.gbl&rnum=1&prev=/groups%3Fas_q%3Dchart% 2520export%2520registry%26safe%3Dimages%26ie%3DISO-8859-1% 26as_ugroup%3Dmicrosoft.public.excel.*%26lr%3D%26h l%3Den . |
