Common Select Buffer tool

How to use

If the sample has associated data, you will find that the sample's zip file includes a "data" folder alongside the language folders. However, you will need to update the sample to point to the location of the data once you have extracted all the files.

1. 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.
2. In Windows Explorer, navigate to <ArcGIS Developer Kit install location>\Samples\ServerNET\Common_SelectBufferTool.
3. Open the folder of the language you're going to use—CSharp or VBNet—and copy the Common_SelectBufferTool_<language> folder to c:\inetpub\wwwroot. The <language> variable can be either CSharp or VBNet.
4. Open the IIS Manager from Control Panel > Administrative Tools > Internet Information Services (IIS) Manager or Internet Information Services.
5. In the console tree view on the left, navigate to Local Computer > Web Sites > Default Web Site, expand Default Web Site, right-click the Common_SelectBufferTool_<language> folder, and click Properties. The Properties dialog box opens.
6. Click the Directory tab, click the Create button in the Application Settings section, then click OK to close the Properties dialog box.
7. Start Microsoft Visual Studio 2008 or 2010 and open the Common_SelectBufferTool_<language><vs_version> solution (for example, Common_SelectBufferTool_CSharp2008.sln) located in c:\inetpub\wwwroot\Common_SelectBufferTool_<language>. The <vs_version> references the Visual Studio version of the solution, either 2008 or 2010.
8. In Solution Explorer, right-click Default.aspx, and select Set As Start Page.
9. 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 opens.
10. Add or change the MapResourceItem associated with a map service (ArcGIS Server, ArcIMS, and so forth).
11. 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 14.
12. At design time, the identity of the user running Visual Studio is used to connect to an ArcGIS 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 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 Solution Explorer and selecting the Add ArcGIS Identity option. Enter the identity credentials that will be used to access ArcGIS 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 web.config check box is checked, the identity tag is encrypted; otherwise, the username and password are stored as clear text.
13. Open the web.config file, add an <identity> element in <system.web>, set the impersonate attribute to true, and add a username and password attribute and set them to a valid user account. If you're working with ArcGIS Server local data sources, ensure the account has access to the geographic information system (GIS) server resources referenced in the Map control.
14. Save the project.
15. Click the Debug drop-down menu and click Start Debugging.

1. Browse to the viewer uniform resource locator (URL) (for example, http://localhost/Common_SelectBufferTool_CSharp).
2. Click a layer in the Toc or use the Select Features In drop-down box to activate a layer from which to select features.
3. In the toolbar above the map, click Select Features.
4. Click and drag a rectangle on the map that intersects features in the active layer. Features that intersect the rectangle are added to the ElementGraphicsLayer in the Selection Graphics resource and displayed above other resources in the map. A GraphicElement is created for each feature before being added to the ElementGraphicsLayer.
5. Check the Display Selection in Table check box, and use the Select Features tool to make another selection on the map. The attributes of the selected features are rendered at the bottom of the page in a GridView.
6. In the toolbar above the map, click Buffer Point - Select Features. The Buffer Distance text box opens.
7. Enter a distance in map units, and click the map to generate a buffer and select features. The buffer polygon is rendered in semi-transparent yellow, and the selected features are rendered in semi-transparent green.
8. Depending on the map units, you may need to set the value of the flattening variable in the buffer tool code. A value for decimal degrees and meters or feet is provided. The flattening value is used to determine the distance between vertices in the buffer polygon.
