GP SDK EXAMPLE - ENHANCEMENT

ChristineZeller — Thu, 02 Dec 2010 14:44:05 GMT

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.

Nakul,

Thanks for the response! I really appreciate the help. I got your code up and running and the zip file is now being delieved to me, which is very cool.

I've been working on this for a few days and was hoping I could ask another question or two:o

I got you sample/code up and running and it works great! THANKS! I was trying to tweak it to make both output paramters return (the clipped counties and the zip file) but I was having trouble. Also I was wondering if there is a way to return the zip as a hyperlink instead of the instant download splash?

Basically, I thought if I got this sample up and rolling I would have a solid example to help me get my own model up and going, which is doing something similar. My model task the user input (a drawn line) and select a feature layer (parcel layer) and then does a buffer around the selected set. It then does some simple calculations, clips, adds, deletes and creates a few excel files that are zipped and it adds this same calculated tables to a html file so the user can eiter view the report in Xcel or in a HTML file.

my model has the following

Input parameters:

Buffer Distance - Data Type: GPLinearUnit
User Drawn Graphic PolyLine - Data Type: GPFeatureRecordSetLayer
Title for a html page - Data Type: GPString

Output Parameters:

BufferedParcels - GPFeatureRecordSetLayer
Output Zip file - Data Type: GPDataFile
Output HTML file - Data Type: GPDataFile

So basically if I can get your previous code outputting both parameters shouldn't I be able to add the thrid output (HTML FILE), flip out the clipped counties with the buffered parcels and add a input parameter for the html title and be up and going?

Thanks for all your time and help, I appreciate it.

Christine.

For returning a hyperlink instead of download splash you may use hyperlink button

Here are code changes in the code xaml file and the code behind

<Grid HorizontalAlignment="Left" VerticalAlignment="Bottom" Margin="0,15,15,0" >
            <HyperlinkButton x:Name="button1" Visibility="Collapsed" Height="19" Width="auto"  Foreground="Black" />
        </Grid>

if (ev1.Parameter is GPDataFile)
                {
                    GPDataFile gpdata = ev1.Parameter as GPDataFile;
                    Uri uri = new Uri(gpdata.Url);
                    button1.NavigateUri = uri;
                    button1.Content = uri;
                    button1.Visibility = System.Windows.Visibility.Visible;
                    //System.Windows.Browser.HtmlPage.Window.Navigate(uri);
                }

Re: GP SDK EXAMPLE - ENHANCEMENT

ChristineZeller — Tue, 07 Dec 2010 19:26:02 GMT

Thanks again Nakul,

I will give your code a shot and see if I can return the hyperlink.

One more question: Can you tell me how to return both parameters (Clipped Counties and the ZIP)

I tried to uncomment out the code you commented out but no luck.

geoprocessorTask.GetResultDataAsync(e.JobInfo.JobId, "Clipped_Counties");
geoprocessorTask.GetResultDataAsync(e.JobInfo.JobId, "output_zip");

JackCibor — Fri, 10 Dec 2010 19:39:16 GMT

I am also trying to figure out how to return multiple output parameters from the same Async GP Task Job. Does anyone have any C# code examples for how you do that.

Nakul,

Thanks again for all your posts! I was able to get your code and the sample up and running...very cool.

I was hoping you or someone might be able to take a look at what I have and shed some light on what I'm doing wrong. My process just runs and runs; it never stops and/or never sends an error or results. The only thing I'm really doing different is my polyline is selecting a Parcel layer and then creating a buffer distance which is in Feet not Miles (the SDK example is in Miles). Also, I don't have map extent set in my xaml. I guess the other thing that might be causing the problem is my mxds are in 102100 projection and my model/geotask: the geopolyline input parameter is in spatial ref 4269 and my BufferedParcels Output parameter is in spatial ref 2230. BUT it works in a straight out the box Server app (.NET API 9.3.1).

Oh and here's the message/error I see in Fiddler

Here's the only message I'm getting from Fiddler:

O.K. I dropped the HTML TITLE Parameter from my model (I figured I have yet to program anything to handle that parameter input so I just took it out of the model) and I got a little further.

Here's the error message I see in fiddler:

{"paramName":"BufferedParcels","dataType":"GPFeatureRecordSetLayer","value":{"geometryType":"esriGeometryPolygon","spatialReference":{"wkid":102100},"features":[],"exceededTransferLimit":"false"}}

and here's the next message:

{"error":{"code":500,"message":"Unable to get value of param 'BufferedParcels' for Job ID 'j8eecb54381584c1bae096002ff8db4e5'. The job may not exist or it could still be executing or could have failed.","details":[]}}

I also checked the arcgis jobs directory to see what was created and the model does run and everything is created in the arcgisserver/arcgisjobs/geoprocesstest_gpserver directly but I noticed something about my selected buffered parcels......THE SHAPEFILE IS EMPTY, which is giving me empty results across the board.

SO my next question is (maybe I should start and new post for this one) Does it matter that my Parameteres are in different projects???

My GPFeatureRecordSetLayer (esriGeometryPolyline - User/parameter input) is in a different projection than the layer that is being selected and buffered by the Input Parameter and the entire mxd is in a different projection.

The .Net out of the box can handle this but can a silverlight app?

Christine.

Christine,

The different projections should not matter...

Just add this to have a parameter for you HTML TITLE.

Code behind:

parameters.Add(new GPLinearUnit("Linear_unit", esriUnits.esriMiles, Int32.Parse(DistanceTextBox.Text)));

Then Uncomment your text box for the html title in your xaml.

John,

Thanks for the reply. I was able to get the html title paramater to start working and I was able to get the model to work when I am only returning one parameter (clipped buffered parcels) but when I add a 2nd parameter to add a zip file or the html file to be return I'm getting following message in fiddler...

First I see the model run successfully:

{"type":"esriJobMessageTypeInformative","description":"Zip file created successfully"},{"type":"esriJobMessageTypeInformative","description":"Completed script Zip..."},{"type":"esriJobMessageTypeInformative","description":"Executed (Zip) successfully."},{"type":"esriJobMessageTypeInformative","description":"End Time: Wed Dec 15 09:27:20 2010 (Elapsed Time: 2.00 seconds)"},{"type":"esriJobMessageTypeInformative","description":"Executed (Model) successfully."},{"type":"esriJobMessageTypeInformative","description":"End Time: Wed Dec 15 09:27:20 2010 (Elapsed Time: 1 minutes 33 seconds)"},{"type":"esriJobMessageTypeInformative","description":"Succeeded."}]}

2nd I get this message in Fiddler:

{"paramName":"Output_htm__2_","dataType":"GPDataFile","value":{"url":"http://gisserver/arcgisjobs/geoprocesstest_gpserver/j352194ced45c45e7884a0e813a1d965a/scratch/Output.htm"}}

Lastly I get this message in fiddler:

I see the clipped buffered feature (1st output parameter returned) returned to the applicaiton but I don't see the second parameter (zip file).

I'm wondering if it has something to do with the last message - exceededTransferLimit":"false"}}

The application just runs and runs!

Is there a way to increase the transferlimit?

I might just start a new post for this one problem.

Nakul, John, and Jay

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
