Finally I figure it out, the following code from the ArcGIS help: datasets = arcpy.ListDatasets(feature_type='feature') datasets = [''] + datasets if datasets is not None else []     for ds in datasets:         for fc in arcpy.ListFeatureClasses(feature_dataset=ds):             PATH = os.path.join(arcpy.env.workspace, ds, fc)             with arcpy.da.SearchCursor(PATH, ["*"]) as cursor:                 for row in cursor:                     tupleList.append(row) ...

Hi Jake, I fortunately found this topic but I got an issue while I count not save the map description which I got an error: Traceback (most recent call last):   File "<string>", line 254, in run_nodebug   File "C:\DEV\CWPP\TileMap.py", line 23, in <module>     College_station_mxd.save()   File "C:\Program Files (x86)\ArcGIS\Desktop10.3\ArcPy\arcpy\utils.py", line 182, in fn_     return fn(*args, **kw)   File "C:\Program Files (x86)\ArcGIS\Desktop10.3\ArcPy\arcpy\_mapping.py", line 850, in save     return convertArcObjectToPythonObject(self._arc_object.save(*gp_fixargs((), True))) IOError: MapDocObject: Unable to save.  Check to make sure you have write access to the specified file and that there is enough space on the storage device to hold your document. I don't know how can solve this. Any idea?Thanks, Peter ... View more

Thanks for the suggestion. I got something confused which is how to turn the ArcGIS API for JavaScript Sandbox into a widget code, especially when I plan to have the two functions initToolbar and addGraphic: function initToolbar() {           tb = new Draw(map);           tb.on("draw-end", addGraphic);           // event delegation so a click handler is not           // needed for each individual button           on(dom.byId("info"), "click", function(evt) {             if ( evt.target.id === "info" ) {               return;             }             var tool = evt.target.id.toLowerCase();             console.log(tool);             map.disableMapNavigation();             tb.activate(tool);           });         } in this function, tb.on("draw-end", addGraphic); I don't know how to invoke the "draw-end" function by calling the addGraphic.         function addGraphic(evt) {           //deactivate the toolbar and clear existing graphics           tb.deactivate();           map.enableMapNavigation();           // figure out which symbol to use           var symbol;           if ( evt.geometry.type === "point" || evt.geometry.type === "multipoint") {             symbol = markerSymbol;           } else if ( evt.geometry.type === "line" || evt.geometry.type === "polyline") {             symbol = lineSymbol;           }           else {             symbol = fillSymbol;           }           map.graphics.add(new Graphic(evt.geometry, symbol));         } I am trying to understand the enableMapNavigation() function, it seems that there is not such function anymore. Any idea? Thanks, ... View more

Hi I am kind of in struggling in simplifying the eDraw example widget for a simple use. What I plan to do is: 1) Draw polygon on the map 2)Turn the draw result (graphics) into feature set, I have seen some code like this: var featureSet = new FeatureSet(); var features = []; features.push(map.graphics.graphics[0]); featureSet.features = features; 3) use derived featureset to clip with other layers(e.g. another polygon layer or point layer) for spatial analyses. However I couldn't figure out how can I accommodate this code into the existing example. Could you provide some hints? Thanks, Peter ... View more

Never mind, I think now it is working, instead use button, I copied from the eDraw example <input type="button" class="jimu-input blue-button" value="${nls.extract}" data-dojo-attach-event="ondijitclick:extractData"/> and add the extratData function in the Widget.js but I didn't included 'dijit/form/Button' because there is no require keywork anymore. I am kind of still struggling in simplifying the eDraw example widget this time. What I plan to do is not that complex but: 1) Draw polygon on the map 2)Turn the draw result (graphics) into feature set(I have seen some code like this: var featureSet = new FeatureSet(); var features = []; features.push(map.graphics.graphics[0]); featureSet.features = features; However I couldn't figure out how can I accommodate this code into the existing example. Has anyone done this before? Thank you all for so many help. ... View more

Qun Sun​ I checked the resources that from the eDraw widget and follow your suggestions, however, I still have the problem. How can I the follow the spec that you mentioned(where can I find them, for e.g., if I want to add a button to the widget, how many step I should go through)? Thanks, ... View more

Hi, did you get this resolved? I looked into an example: Clip and ship | ArcGIS API for JavaScript But was told that the Extract GP Service no longer exists on the sample server, I hope it can be resolved and helps. Peter ... View more

I do find both of the file in the folder your mentioned: a config.json in the \client\stemapp\widgets\PrintPlus folder and the property in the apps\2\config.json file "config": "configs/PrintPlus/config_Print Plus.json" I tried to change the file name from config.json to config_PrintPlus.json However, I still get the same error and the frame(red) not showing up. There is a file named "Configuration Properties for the Print Plus Widget.pdf" in the \client\stemapp\widgets\PrintPlus folder, however, I could not understand "Use this document along with the config.json file in the Widget’s root directory." this sentence, where is the root directory? what means use this document along with?Should I do some change in the config.json file? ...

I did the step "right click on the "PrintPlus-1.1.2-2015-4-11.zip" link and choose "Save Link As..." and then unzip the contents and copy the PrintPlus folder over to your \client\stemapp\widgets folder", and I created a new app the Print Plus widget, the widget shows up on my application, and I copied the "serviceURL": "http://utility.arcgisonline.com/arcgis/rest/services/Utilities/PrintingTools/GPServer/Export%20Web%20Map%20Task" from the config.json to the \client\stemapp\config.jon (Not sure if I am correct), however, there was no the red frame show up and when I click print it says "error, try again", am I doing correct? ...
