我认为在关闭缩放滑块后，您需要从地图中侦听UPDATE_COMPLETE事件。map.addEventListener (FlexEvent。UPDATE_COMPLETE onUpdateComplete_handler);地图。zoomSliderVisible = false;function onUpdateComplete_handler(e:FlexEvent):void {map.removeEventListener(FlexEvent。UPDATE_COMPLETE onUpdateComplete_handler);createPDF ();} …查看更多

我是用雅虎astra一个，但我开始使用这个，当我移动到Flex 4 http://flashcommander.org/blog/flex-4-autocomplete它对我来说很好。 …查看更多

嗨，罗伯特，我只是想给你一个大大的感谢。我想确保你没问题，我已经添加了你的函数来构建swatches在我的签名flex库中的函数。我找不到你的电子邮件，否则我就直接发了。我举了一个例子来说明我是如何使用它的。再次感谢。 …查看更多

罗伯特，谢谢你帮我跑腿。我正在合并/调整你的方法来创建色板到我拥有的当前图层可见性组件。编写/调试这些渲染器符号一定花了你很长时间。 …查看更多

你可以输入XML -> Array或ArrayCollection不要忘记设置结果格式。服务。resultFormat = "e4x";var xml: xml =事件。结果为XML;var items:Array = [];for each (var queryXML:XML in XML. tipproject) {var obj:Object = {project:queryXML。@project、代理:queryXML。@agency //依此类推添加你想要的字段}items.push(obj);}您也可以将其转换为XMLListCollection var XMLListCollection:xmlListCollection。source = new XMLList(事件列表)。结果); You can then treat the XMLListCollection like an ArrayCollection When dealing with an HTTPService, your results are easy to parse in XML, I never used ArrayCollection with an HTTPService result, but I think the event.result object is xml by default. …查看更多

.NET web服务访问SDE的一个例子可能看起来像这样[WebMethod(Description = " return FlowControlHistory Details")] public DataTable FlowControlHistory(String objectID) {DataTable FlowTable = new DataTable();System.Data.OleDb. oledbconnection连接= new System.Data.OleDb. connectionOleDbConnection("<您的连接字符串这里>");connection.Open ();//创建一个sql表达式来访问你的数据库数据//使用一个传入的objecd从一个flex字符串的特性strSQL = "SELECT DISTINCT t1。从侧面流动“+”。SSCOMPLEXFLOWCONTROLHISTORY作为t1“+”WHERE t1。objecd = ' '" + objecd + "' " + "UNION " + "SELECT DISTINCT "从侧面流动“+”。SSFLOWCONTROLHISTORY作为t2“+”WHERE t2。OBJECTID = '" + OBJECTID + " "' " + "ORDER BY flow;System.Data.OleDb. oledbdataadapterOleDbDataAdapter (strSQL、连接);Adapter.Fill (FlowTable); try { FlowTable.TableName = "Table"; } finally { connection.Close(); } return FlowTable; } Then in Flex, you'd do something like this. protected var service:WebService; protected var retry:uint = 0; // send your Web Service WSDL to define a web service public function setWsdl(value:String):void { service = new WebService(); service.showBusyCursor = true; service.wsdl = value; service.addEventListener(FaultEvent.FAULT, WsdlFault, false, 0, true); service.loadWSDL(); } protected function onWsdlFault(fault:FaultEvent, token:Object = null):void { // I always try to load a web service twice if I get a load error. // Just in case, my network can laugh at me sometimes retry++; if (retry < 2) service.loadWSDL(); else { service.removeEventListener(FaultEvent.FAULT, WsdlFault); Alert.show("A Web Service has failed to load. Please close the application and try again.", "Error"); } } // function that will call my web service public function findRelatedFlowData(objectID:String):void { var responder:AsyncResponder = new AsyncResponder(onFlowDataResults, onFault); var request:AsyncToken = service.FlowControlHistory(objectID); request.addResponder(responder); } proteced function onFlowDataResults(result:ResultEvent, token:Object = null):void { var ac:ArrayCollection = result.result.Tables.Table.Rows; // do something with results here } protected function onFault(fault:FaultEvent, token:Object = null):void { // I always try to load a web service twice. Alert.show("A Web Service error has occurred.", "Error"); } This has always worked for me, plus by using C# or VB.NET you get a bit more control over your query. The relates in the ESRI API are still great and I use them for large data dumps, but I still have a lot of these unique queries of my SDE. …查看更多

编辑，刚刚看到你在上面发布的最后一条评论。根据我的经验，Web服务快速、简单，通常是访问外部数据的好工具。您可以使用您选择的。net风格创建一个web服务，它将查询您的SDE或任何其他数据库来模拟您的关联。给它传递一个名称，id，等等。根据结果的大小，它可能会有点慢。我已经用这个方法好几年了，效果很好。上述场景的典型方法。选择地图上的图形(你也可以这样做。如果你想在得到识别结果)属性字段值传递给web服务使用服务响应填充列表/ DataGrid web服务是非常简单的设置在。net和http://msdn.microsoft.com/en-us/library/8wbhsy70.aspx代码很简单简单的路线是返回一个DataTable和flex将返回作为一个像event.result.Tables ArrayCollection。< TableNameHere >。以这种方式进行查询的一个好处是，您可以执行任何join / union或更改您可能希望传递给应用程序的字段名称，以使您自己更轻松。 …查看更多
