SDS Layer with Feature Service from ArcGIS Server in Engine C#

April 17, 2013, 5:47 pm

Hi :cool:

I've developed an application in ArcGIS Engine in C#.net that works perfectly with anything local (gdb, shape, raster, dwg)
and now I'm trying to get it working with ArcGIS Server layers etc.

trying to consume a Feature Service with Editing/Query/Create/Delete enabled.... the map control accepts the layer, and displays the data. "/SpatialDataServer/admin/services/Sandbox_TestLayer.FeatureServer/0"

however upon Query / add feature / edit, it seems the layer needs to be treated differently..
it edits and queries fine in ArcMap 10.1, so i'm just wondering how I need to cast the ILayer to be able to use it?

currently there's alot of conflicting information floating around, and I just need to know the right way to handle this.

I've looked into GISClient / MapServerLayer / AGSFeatureLayer ... but having trouble determining from the ILayer the "LayerType" i.e. if its from the server... / feature service layer.... any point in the right direction would be great.. as i'm new to this stuff..

I know its possible to consume it all through REST and geoJSON, but I'm assuming ESRI has a better way in ArcObjects to do this for me rather than me having to manually consume it all..

ArcGIS 10.1, Delphi XE2 and licensing

Hi everyone,

We have a project on Delphi 5 and we need to upgrade it for Delphi XE2.
Everything went well until it came to the components of ArcGIS.
The problem is that I need to check the license for Desktop and Engine.
I found these two threads:
http://forums.arcgis.com/threads/262...-and-licensing

http://forums.arcgis.com/threads/605...-and-licensing

When including libraries ArcGISVersionLib_TLB, esriControls_TLB, esriSystem_TLB, ComObj I thought that everything would work but the project returns the following errors:

undeclared identifier TMapControl, TVersionManager, TAoInitialize

in the code:

public
{ Public declarations }
MapControl:esriControls_TLB.TMapControl;
verManager: arcGISVersionLib_TLB.TVersionManager;
aoInit: TAoInitialize;

any ideas?
Thanks beforehand.

ADF and ADF Local DLL

I need to use ComReleaser, BaseCommand and MxCommand.

The simple solution is to use ESRI.ArcGIS.ADF since it has these classes. However, the compiler complains:

Quote:
The type 'ESRI.ArcGIS.ADF.BaseClasses.BaseCommand' is defined in an assembly that is not referenced. You must add a reference to assembly 'ESRI.ArcGIS.ADF.Local, Version=10.1.0.0, ...
And if I add that reference, it complaints that I have duplicate:
Quote:
The type 'ESRI.ArcGIS.ADF.CATIDs.MxCommands' exists in both 'C:\Program Files (x86)\ArcGIS\DeveloperKit10.1\DotNet\ESRI.ArcGIS.ADF.Local.dll' and 'C:\Program Files (x86)\ArcGIS\DeveloperKit10.1\DotNet\ESRI.ArcGIS.ADF.dll'
How do I resolve this issue? Is there a way to explicitly specify which dll to load the class from?

Please help.

Bind combo box with data and display results

Dear all,

Currently, I am developing a simple application that contains 2 drop down lists, namely, products as well as price list.
The product drop down list has 4 options and how do I bind this drop down list with the values in the table so that I do not need to
pre-define the values. Additionally, this is also useful in the future because if there are new products, I can simply update the database
and the values will be automatically reflect in the drop down list.

I found a sample code that binds drop-down list with data from the database. Is this set of code suitable of for the web form in
arcGIS?

ddlProduct.DataSource = Product_Table
ddlProduct.DataSource.DataTextField = ‘Product_Name”
ddlProduct.DataSource.DataValueField = ‘Product_Name”
ddlProduct.Databind()

Second to retrive records from the database, I have generated a sql statement:
Secondly, the first field is mandatory while the price list is optional. This means the user can perform 2 types of search.
• Product
• Product + Price List

This is the SQL statement that I have generated:

Select * from Product_Table where Product_Name = “Printers” OR “ Scanners” OR “Laptops” AND Price_List = “100-200” OR “200-400” OR “400-600” OR “600-800” OR “800-1000” OR “”

How do i populate display results in data view because i tried to search for codes but cant find any

Thanks

Namaste, Hola, Hi

Using the Code below I have created a Line geometry using Rubberbanding

public void DrawPolyline(ESRI.ArcGIS.Carto.IActiveView activeView)
{
if(activeView == null)
{
return;
}
ESRI.ArcGIS.Display.IScreenDisplay screenDisplay = activeView.ScreenDisplay;

screenDisplay.StartDrawing(screenDisplay.hDC, (System.Int16)ESRI.ArcGIS.Display.esriScreenCache.esriNoScreenCache); // Explicit Cast
ESRI.ArcGIS.Display.IRgbColor rgbColor = new ESRI.ArcGIS.Display.RgbColorClass();
rgbColor.Red = 255;

ESRI.ArcGIS.Display.IColor color = rgbColor; // Implicit Cast
ESRI.ArcGIS.Display.ISimpleLineSymbol simpleLineSymbol = new ESRI.ArcGIS.Display.SimpleLineSymbolClass();
simpleLineSymbol.Color = color;

ESRI.ArcGIS.Display.ISymbol symbol = (ESRI.ArcGIS.Display.ISymbol)simpleLineSymbol; // Explicit Cast
ESRI.ArcGIS.Display.IRubberBand rubberBand = new ESRI.ArcGIS.Display.RubberLineClass();
ESRI.ArcGIS.Geometry.IGeometry geometry = rubberBand.TrackNew(screenDisplay, symbol);
screenDisplay.SetSymbol(symbol);
screenDisplay.DrawPolyline(geometry);
screenDisplay.FinishDrawing();
}

After Drawing a Line geometry using Rubberband, I would like to save the "geometry" as a feature in a FeatureClass and create a Feature Layer and display the layer. I am facing trouble in creating feature class and saving a feature. Please help me with some sample Code .. I am badly waiting for some reply.

Hi. I try to draw line on map.

Code:
public static List<IPoint> pointness=new List<IPoint>();
 private void button1_Click(object sender, System.EventArgs e)
        {
            IPoint points = new PointClass();
            points.PutCoords(x, y);
            pointness.Add(points);
            ILine pLine1 = new LineClass();
            if (pointness.Count > 1)
            {
                for (var i = 0; i < pointness.Count - 1; i++)
                {
                    pLine1.PutCoords(pointness[i], pointness[i + 1]);
                }
            }
        }
I have List of points. Coordinates of point is coordinates of mouse, when it's click on map. To list points adds allright, but don't drawed.
Why? Maybe i set bad coordinates? I use coordinates like in Identify Tool.

Hi,
I want to add an index to a feature class. To do so, I use the very short and complete example given there:
http://resources.esri.com/help/9.3/a...35f906bb2e.htm

When I use this code, I obtain an exception due to a Castproblem:
It cannot cast from a IFeatureClass to a ISchemaLock:
Exception in thread "main" java.lang.ClassCastException: com.esri.arcgis.geodatabase.IFeatureClassProxy cannot be cast to com.esri.arcgis.geodatabase.ISchemaLock

Are you able to run this code sucessfully ?

You have to change the 2 first inputs in the code (the path and name of your shapefile)

Hello,

I know how to listen to edit events, but I would like to fire an edit event myself. Does anyone know how to do this?
I tried the following (in C#):

Code:
UID editorUid = new UIDClass();
editorUid.Value = "esriEditor.Editor";
IEditor editor = _app.FindExtensionByCLSID(editorUid) as IEditor;

IEditEvents editEvents = editor as IEditEvents;
if (editEvents != null)
{
    editEvents.OnCurrentLayerChanged();
}
However, the QI from IEditor to IEditEvents doesn't work, editEvents is null.

Dear Developers,
I am extending ArcObject with .NET. I am not sure what is the difference between the following two sentences:

Dim pt as IPoint = new Point
Dim pt2 as IPoint = new PointClass

From the intelisense prompt I can only see Point but not PointClass. In this case, do I have to add Class manually every time I define new CoClass? That will be painful. Also, when I use new Point, it works without any problem.

Thanks for your clarification,

cast from IFeatureClass to ISchemaLock (ARCGIS)

Hi

I'm programming with the ARCGIS Java SDK, in Eclipse.

I need to cast an IFeatureClass to an ISchemalock. This cast is supposed to be allowed. There is an example of this cast in: http://resources.esri.com/help/9.3/a...35f906bb2e.htm

However, when I try to perform this cast in my code, an exception appears:

Exception in thread "main" java.lang.ClassCastException: com.esri.arcgis.geodatabase.IFeatureClassProxy cannot be cast to com.esri.arcgis.geodatabase.ISchemaLock

Are you able to make this cast on an IFeatureClass ? Here is the code to perform this:
Code:
//Attempt to acquire an exclusive schema lock on the feature class.
ISchemaLock schemaLock = (ISchemaLock)featureClass;
I would appreciate if you could try this simple line of code in one of your programs, and let me know if you get an exception.

Keep me posted...

Migration from 10 to 10.1

I am relatively new to using the ArcGIS libraries, so forgive me if this is off target.

Apparently the historical approach is to move client installs to the latest ArcGIS, and then the SDE server at a later date.

Hence, at the moment, we've moved our client code base to run against 10.1, connect to a 10.1 Licence Server, but connect to the 10 SDE database.

I've updated the C# code to reference the 10.1 assemblies, compiles ok, however when running I get a COMException "The operation was attempted on an empty geometry" (PointClass).

Should I be able to run as described (client 10.1, Licence Server 10.1, SDE 10)?

Or do I need to migrate code as part of the move from 10 to 10.1?

Thanks
