Beijing ArcGIS Server Development Training example (organized)

Some time ago, I went to Beijing to attend ESRI's ArcGIS Server application development training. I found that the examples are basically the same as those in the arcgsi server development series above flyingis, except for the last two examples. Because the training Party does not provide source code, all test examples made during training cannot be copied. Alas, there is no way. After the training is completed, sort it out and put it up for future reference!

 

Examples include

1. Web ADF programming-Implementation of the query function

2. Graphics daTa sources-highlight implementation

3. ArcGIS Server daTa sources -- Implementation of the buffer function

4. Custom Tool

5. Custom tasks

6. Extended ArcGIS Server

 

As the previous five examples are described in detail in the flyingis blog, I will not introduce them here. Here we will mainly introduce the last example to expand ArcGIS Server.

 

Objectives:

Extended ArcGIS Server to obtain the province area based on the province name

Of course, this is just an example. You can make complicated extensions.

 

Preparations before the test:

1. Prepare map data for each province

2. Create a map document for Province

3. Publish a map service through the map document of Province

 

Test procedure:

1. Compile the class implementing iserverobjectextension, that is, the function you want to add, create a daansoe project, add a class file, and change the nameThe code for getarea. CS is as follows:

2. Use regasm to Register Server Object Extension

Enter the command prompt box in vs2005:

E: \ Program Files \ Microsoft Visual Studio 8 \ Vc>

 

Switch the current directory to the directory where the above DLL is located:

E: \ project \ Beijing training \ beijingtraining \ exercise11 \ daansoe \ bin \ debug>

 

Run the following command for registration:

Regasm/TLB: daansoe. TLB/codebase daansoe. dll

 

After execution, you can go to the dll Directory to verify whether the corresponding. TLB is generated.

 

(If you want to cancel registration, use the regasm/u daansoe. dll/TLB daansoe. TLB/codebase command)

 

3. Register Server Object extension to GIS server

We will use a piece of code to register the server object extension to the GIS server.

Create a console project with the command registertogisserver. Add the following code in the main method:

C # code

1. <Span style = "color: #000000"> identity =NewIdentity ("username", "888888", "Domain ");
2. Agsserverconnection connection =NewAgsserverconnection ("fmc-pca187", identity );
3. Connection. Connect ();
5. Iserverobjectadmin2 SOA = connection. serverobjectadminAsIserverobjectadmin2;
6. Iserverobjectextensiontype SOE = soa. createextensiontype ();
7. Soe. CLSID = "daansoe. soeserver ";
8. Soe. Name = "soeserver ";
9. Soe. Description = "test application ";
10. SOA. addextensiontype ("mapserver", SoE); </span>

Identity identity = new Identity("username", "888888", "domain");            AGSServerConnection connection = new AGSServerConnection("fmc-pca187", identity);            connection.Connect();            IServerObjectAdmin2 soa = connection.ServerObjectAdmin as IServerObjectAdmin2;            IServerObjectExtensionType soe = soa.CreateExtensionType();            soe.CLSID = "DAANSOE.SOEServer";            soe.Name = "SOEServer";            soe.Description = "Test Application";            soa.AddExtensionType("MapServer", soe);

Run this code. After execution, go to <ArcGIS Server install location> \ Server \ system folder to open servertypesext. dat for verification.

 

4. Stop the province service, right-click the Service Properties capabilities, hook the soeserver, and restart the province service.

 

5. Use Server Object Extension

Create a new web application, create a new ASPX page, change it to useextensiongisserver. aspx, and add the corresponding controls. In the Click Event of the button, implement the following code:

C # code

1. <Span style = "color: #000000"> identity =NewIdentity ("username", "888888", "Domain ");
2. Agsserverconnection connection =NewAgsserverconnection ("fmc-pca187", identity );
3. Connection. Connect ();
5. Iserverobjectmanager som = connection. serverobjectmanagerAsIserverobjectmanager;
6. Iservercontext servercontext = som. createservercontext ("Province", "mapserver ");
7. Iserverobjectextensionmanager soem = servercontext. serverobjectAsIserverobjectextensionmanager;
8. Iserverobjectextension SOE = soem. findextensionbytypename ("soeserver ");
10. Iactcarea paear = SoeAsIactcarea;
11. DoubleArea = paear. getarea (textbox1.text. tostring ());
13. Servercontext. releasecontext ();
14. Response. Write ("<SCRIPT> alert (" + area. tostring () + "); </SCRIPT>"); </span>

Identity identity = new Identity("username", "888888", "domain");        AGSServerConnection connection = new AGSServerConnection("fmc-pca187", identity);        connection.Connect();        IServerObjectManager som = connection.ServerObjectManager as IServerObjectManager;        IServerContext serverContext = som.CreateServerContext("province", "MapServer");        IServerObjectExtensionManager soem = serverContext.ServerObject as IServerObjectExtensionManager;        IServerObjectExtension soe = soem.FindExtensionByTypeName("SOEServer");        IActcArea pAear = soe as IActcArea;        double area = pAear.GetArea(TextBox1.Text.ToString());        serverContext.ReleaseContext();        Response.Write("<script>alert(" + area.ToString() + ");</script>");

The preview effect is as follows:

 

Now, if everything goes well, the entire function is complete. Click OK to bring up the area of Sichuan Province.

 

Note:

If the server object extension is registered with ArcGIS Server and the Province service is started again, if daansoe is to be generated again, stop province. Otherwise, an error will occur, then use regasm to register the modified DLL.

 

Finally, I uploaded the entire project of the above examples as an attachment. These examples are all debugged on the local machine. You need to modify the identity parameter after downloading, any questions can be raised here!
