Hi For a featureclass of polylines with 2 vertices each, I want to be able to keep the line itself, startpoint and the angle, but move endpoint to a specific length. I am doing this in a versioned geodatabase, and currently I can put a new line into the geometry, but the problem is, there are featurelinked annotations which are reset, when the whole line is changed. I wonder whether it is possible, since I already am in edit mode, to just move lastpoint of the existing line? Perhaps this is not possible with arcpy? Best Regards Marianne Wiese import arcpy, time, traceback arcpy.env.workspace = 'Database Connections/mbw.sde' inFeatures = 'G100.geopoint_mbw_20130930/G100.geopoint_line_2' newLength = 550 n = 0 try: uCursor = arcpy.da.UpdateCursor(inFeatures, [ 'OID@', 'SHAPE@']) edit = arcpy.da.Editor(arcpy.env.workspace) edit.startEditing() edit.startOperation() for row in uCursor:   line = row[1]   factor = newLength/line.length   X2 = line.firstPoint.X + factor * (line.lastPoint.X - line.firstPoint.X)   Y2 = line.firstPoint.Y + factor * (line.lastPoint.Y - line.firstPoint.Y)   array = arcpy.Array([line.firstPoint, arcpy.Point(X2,Y2)])   newLine = arcpy.Polyline(array)   row[1] = newLine   uCursor.updateRow(row)   n += 1   if (n % 1000 == 0):    print time.strftime('%H:%M:%S'), ':   ', n except: tb = traceback.format_exc() print tb finally: del uCursor edit.stopOperation() edit.stopEditing(True) del edit print 'all done' ...

Hello all I am trying to fetch tiles from our ArcGis Server 10.1 Service using the REST interface. We have a cached map service and according to the help here: �??Unlike other types of OGC services, there is no WMTS capability option to enable when creating a cached map or image service; WMTS is always enabled.�?� I can access for example the Identify service Through REST like this: (example, not working) http://<Mapserverurl>/identify?imageDisplay=400,400,96&tolerance=1&geometry=-25000,7955000&mapExtent=-50000,7930000,0,7980000&layers=all:14 However when I try to get the capabilities and see which tilematrixset was used (custom) http://<Mapserverurl>/WMTS/1.0.0/WMTSCapabilities.xml I get HTTP 400 The request sent by the client was syntactically incorrect(). It seems to work in ESRI�??s documentation here, so I wonder if there is something wrong with our service. Any hint, as to what we are missing? Best regards                                     Marianne B. Wiese ... View more

Hi Forum I am porting a Tool for ArcMap to a Java Addin, and I want to listen to Document events. In the Tools init() function, I do the following, which I found here: ((MxDocument)mxDoc).addIDocumentEventsListener(new IDocumentEventsAdapter(){        @Override public void openDocument(IDocumentEventsOpenDocumentEvent e){          JOptionPane.showMessageDialog(null, "Hey: Document opened!");        } }); However, with this code in its init() function, ArcMap hangs and never opens any Document. ArcMap did not hang when I tried  the newDocument event instead, however a Document that is closed and re-opened will not fire the the newDocument Event. So, if someone could answer any of my questions here, that would be nice: 1) Are we supposed to fire a super.openDocument(e);  after having done our own logic? I tried that, but it did not seem to change anything. 2) Could it be, that I should rather listen to Events in an Extension than in this Tool? It might be, that Extensions are loaded first.. 3) Any other suggestions? In the hope of an answer Marianne Wiese ... View more

Hello Forum I try to implement a custom renderer, that will render a polygon featureclass with unique values. To start, I simply have hardcoded som colors. My draw method code goes like this: // How to render public void draw(IFeatureCursor featureCursor, int drawPhase, IDisplay display, ITrackCancel trackCancel) throws IOException,AutomationException {           try {       int index = featureCursor.findField("GM_LABEL");    if (legendID == 1) {     IFeature feature = featureCursor.nextFeature();     display.setSymbol(blueSymbol());     do{      display.drawPolygon(feature.getShape());      feature = featureCursor.nextFeature();     }while (feature != null);       }    if (legendID == 2) {     renderer.setSymbolByRef(greenSymbol());     renderer.draw(featureCursor, drawPhase, display, trackCancel);     }       if (legendID == 3) {     uvRenderer.setFieldCount(1);     uvRenderer.setField(0, "GM_LABEL");     uvRenderer.setDefaultSymbol(redSymbol());     uvRenderer.setUseDefaultSymbol(true);     uvRenderer.addValue("LAK", null, blueSymbol());     uvRenderer.setLabel("LAK", "Blue");         uvRenderer.draw(featureCursor, drawPhase, display, trackCancel);       }      } catch (Exception e) {    System.out.println(e.getMessage());   }   return; } This is a desktop extension in java. The first option draws directly to display as in the custom renderer example, works well. The second option works via a simple renderer, works well too. The third option is a try to use a Unique Value Renderer, does not render anything. The polygons are not rendered, screen becomes white. Does anybody know, if I am missing something, or if it is not possible to reference another renderer from inside the draw method. Any answer appreciated Marianne B. Wiese ... View more

Hello Forum I have a custom renderer, with a combobox to choose between differerent renderers. It does work as far as the layer gets rendered the first time a selection is done, and the Update button gets disabled. I would like the Update button to be enabled again when I change the selection in the combobox. How can that be done? This button is a general button for all property pages, outside the UI in the custom renderer project. Best Regards Marianne B. Wiese ... View more

Hello Forum I am trying to make a custom renderer as a Java add-in. I made the following very simple code, which paints all polygons green. The strange thing is, that each time i compile this program, it will work the first time I try it out in ArcMap. If I close restart ArcMap, then all polygons get painted in red by this Add-in, which I guess is a sort of fall back behaviour. No error is catched, and the printlines in the draw method are both printed to the console. I make the greenFillSymbol new each time. So I do not understand this behaviour at all. My question is, if anyone out there is actually making Java Add-ins for Desktop extensions? It may be, that I should revert to C++, and wait for another version of ArcGIS before changing to Java. I have attached the sorce.

Hi Forum I have made a little edit utility for ArcMap. It works well, but about once a day ArcMap will close unexpectedly, leaving a message like the attached png. Different dll's like nt.dll, EditTools.dll and Geometry.dll experience uncaught Access Violation Errors. I am not sure if my utility is causing these errors, but they seem to occur more often, when this utility is used. One of the things I am not sure of is my use of ESRI's projection Engine. I followed the advices on this thread: Can I get the Geodesic Angle directly from projection Engine? and it does work. 1) I made a fairly simple class ProjectionEngineWrap as an excerpt from Richie Carmichael's example.  But should I give it a GUID and find it with findExtension()? 2) Should I do something special in order to make it threadsafe? 3) My Class Edithelper uses an instance of ProjectionEngineWrap. When I am finished with the instance, is it sufficient, as I do, to call dispose() and set the member variable to null, or should I do something more? I am using ArcGis 9.3.1 and C# in Visual Studio I would be happy if someone could point me in the direction of more information. Regards Marianne B. Wiese /*  GEUS 2010 *  Author: Marianne B.
