. CloseRs = nothing 'set statement removed.%> The next example is an ASP. NET application that uses ADO. Net to read records from the same northwind database as in the previous example. The output generated by these codes is equivalent to the output in the previous example and has been modified to comply with ASP. NET code block conventions. This example creates an ADO. Net DataSet object. In this case, this object contains a data table, which is used in almost the same way as the ADO record

characteristics. Because the power outage area to be drawn in this graduation project is a dynamic area, it is best to use a Virtual Layer. Therefore, the possibility of server creation is ruled out first. In addition to dynamically drawing a region, you also need to provide regional point query and other functions. Therefore, you can select to operate the image on the web side. WAF provides a unique graphical data source. The graphic data source can be added to the mapresourcemanager control
