GP SDK EXAMPLE - ENHANCEMENT

ChristineZeller

Good Morning,

I am working through getting a Geoprocess Task up and running.  Currently, I am working with SDK example: http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#ClipFeatures. 

I noticed that the task http://serverapps.esri.com/ArcGIS/rest/services/SamplesNET/USA_Data_ClipTools/GPServer/ClipCounties
has the capabilities to generate an output parameter: output.zip file. 

Basically, I wanted to take the current example from the SDK and just enhance it to the point where the output.zip file is delivered to the client. 

I�??m having some trouble and I�??m wondering if someone has already taken this process/sdk example and enhanced it this way.  Could/would you share some pointers/suggestions/code?

Thanks
Christine.

I'm so sorry to post again and ask another question.  I thought I had this figured out:(

I have everything going and I'm trying to add my 3rd output parameter (the zip file).

My first two are returning fine (Clipped Buffered Parcels graphic and an HTML file) and I'm able to get the hyperlink button to appear for the zip file but it is linking to the HTML page so both the html button and the zip button are bring up the htlm output.  Would you mind looking at my code and letting me know what I'm doing wrong.

Thanks again for all the help!
Christine
