ArcGIS Buffer geoprocessing

How to use

1. Verify that the appropriate services are available (see the code description for more details).
2. Verify that the Web ADF for the .NET Framework is installed and functioning properly. For information on installing and configuring the Web ADF, consult the installation guide.
3. In Windows Explorer, navigate to <ArcGIS Developer Kit install location>\ServerNET. This folder contains ArcGIS_Buffer_Geoprocessing CSharp and VBNet folders.
4. Open the folder of the language you are going to use (that is, CSharp or VBNet) and copy the ArcGIS_Buffer_Geoprocessing_<language> folder to c:\inetpub\wwwroot. The <language> variable can be either CSharp or VBNet.
5. Open the IIS Manager from Control Panel, Administrative Tools, Internet Information Services (IIS) Manager or Internet Information Services.
6. In the console tree view on the left, navigate to Local Computer, Web Sites, Default Web Site. Expand Default Web Site, right-click the ArcGIS_Buffer_Geoprocessing_<language> folder, and click Properties. The Properties dialog box appears.
7. Click the Directory tab, click the Create button in the Application Settings section, then click OK to close the Properties dialog box.
8. Start Visual Studio 2010 and open the solution located in the c:\inetpub\wwwroot\ArcGIS_Buffer_Geoprocessing_CSharp folder.
9. In the Solution Explorer, right-click Default.aspx and select Set As Start Page.
10. Open the Default.aspx page in Design view, open the properties window for the MapResourceManager control, and click the ellipsis next to the ResourceItems property. The ResourceItem Collection Editor dialog box appears. One Graphics layer resource is added to store the points added by the user and the buffer geometry returned from the geoprocessing service. The Graphics resource item is not visible in the table of contents (TOC).
11. Add or change the MapResourceItem associated with a map service (for example, ArcGIS for Server, ArcIMS, and so on). Any map service in the same projection as the output for the geoprocessing service will work. In this sample, the CaliforniaProjected map service is provided.
12. Select the GeocodeResourceManager and click the ellipsis next to the ResourceItems property. The ResourceItem Collection Editor dialog box appears.
13. Add a GeoprocessingResourceItem associated with a geoprocessing service (ArcGIS for Server only). In this sample, use the BufferTools geoprocessing service.
14. If necessary, set the run time identity of the Web application by following one of the next two steps. If not necessary, proceed to Step 17.
15. At design time, the identity of the user running Visual Studio is used to connect to an ArcGIS for Server local data source. At run time, that identity is established by the Web application. Only one identity can be used to define access to the ArcGIS for Server local data sources in a single Web application. This identity can be explicitly defined when building the Web ADF application in Visual Studio by right-clicking the Web project in the Solution Explorer and selecting the Add ArcGIS Identity option. Add the identity credentials that will be used to access ArcGIS for Server local resources at run time. This information is added to the web.config file in a standard ASP.NET identity tag. If the Encrypt identity in the web.config check box is selected, the identity tag will be encrypted; otherwise, the username and password are stored as clear text.
16. Open the web.config file, add an <identity> element in <system.web>, set the impersonate attribute to true, add a username and password attribute, then set them to a valid user account. If you are working with ArcGIS for Server local data sources, ensure the account has access to the geographic information system (GIS) server resources referenced in the Map control.
17. Save the project.
18. Click the Debug drop-down menu and click Start.

1. Browse to the viewer uniform resource locator (URL) (for example, http://localhost/ArcGIS_Buffer_Geoprocessing_CSharp).
2. In the toolbar above the map, click Add Points, and click the map to add graphic points.
3. Select the buffer distance units and add a buffer distance.
4. Click Generate Buffer. The geoprocessing service asynchronously processes the request. The activity indicator (animated .gif) below the button displays until the geoprocessing job is finished. An initial JavaScript delay is set to 10 seconds (change this in the JavaScript at the top of the Default.aspx file).
5. Interact with the application while waiting for a response from the geoprocessing service. You can use other controls in the Web application while the geoprocessing service processes the request. When the request is finished, the buffer polygons are drawn on the map as a Web ADF feature graphics layer.
