InfoPath的常见处理办法

1.动态调用WebUrl

　　设置一个字段UrlField,用于存放Url

  public void OnLoad(DocReturnEvent e)
        {
            // Write your code here.
            IXMLDOMNode node = e.XDocument.DOM.documentElement.selectSingleNode("my:UrlField");
            this.WebSiteURL = node.text;
        }

        private void ApplyWebServiceURL(DataObject dataObj)
        {
            WebServiceAdapter adp = dataObj.QueryAdapter as WebServiceAdapter;
            XmlDocument doc = new XmlDocument();
            doc.LoadXml(adp.Operation);
            XmlNode node = doc.SelectSingleNode("//@serviceUrl");
            node.Value = this.WebSiteURL;
            adp.Operation = doc.OuterXml;
        }

　　

2.代码调用WebService

           //找到要调用的dataconnect
            DataObject dataObj = (DataObject)thisXDocument.DataObjects["SaveEvent"];
            if (dataObj == null)
            {
                thisXDocument.UI.Alert("The data connect SaveEvent does not exist.");
                return null;
            }
            //设置Web service的输入参数
            IXMLDOMNode nodeEntry;
            try
            {
                nodeEntry = dataObj.DOM.selectSingleNode("/dfs:myFields/dfs:queryFields/tns:SaveEvent");
                nodeEntry.selectSingleNode("tns:input").text = dataObj.DOM.xml;
            }
            catch (Exception ex)
            {
                string err = ex.Message;
            }
            //调用Web service
            this.ApplyWebServiceURL(dataObj);
            dataObj.Query();
            //得到Web service的返回值，是一个xmldocument，包括projectID,eventID两个值
            IXMLDOMNode nodeResult = dataObj.DOM.selectSingleNode("/dfs:myFields/dfs:dataFields/tns:SaveEventResponse/tns:SaveEventResult");
            string projectID,eventID;
            projectID = nodeResult.selectSingleNode("//ProjectID").text;
            eventID = nodeResult.selectSingleNode("//EventID").text;
