  • Fuzzy match two hash tables?

    - by alex
    Hi, I'm looking for ideas on how to best match two hash tables containing string key/value pairs. Here's the actual problem I'm facing: I have structured data coming in which is imported into the database. I need to UPDATE records which are already in the DB, however, it's possible that ANY value in the source can change, therefore I don't have a reliable ID. I'm thinking of fuzzy matching two rows, source and DB and make an "educated" guess if it should be updated and inserted. Any ideas would be greatly appreciated.

  • Windows application data directory

    - by Stefan
    With the environment variable %allusersprofile% I can get the directory where common settings are stored. But most programs store their settings in the sub-folder "anwendungsdaten" (German, application data). Is there a way to get the direct path to this folder? The problem is that its name is language dependent. Thanks.

  • Possible uncommitted transactions causing "System.Data.SqlClient.SqlException: Timeout expired" erro

    - by Michael
    My application requires a user to log in and allows them to edit a list of things. However, it seems that if the same user always logs in and out and edits the list, this user will run into a "System.Data.SqlClient.SqlException: Timeout expired." error. I've read comments about increasing the timeout period but I've also read a comment about it possibly caused by uncommitted transactions. And I do have one going in the application. I'll provide the code I'm working with and there is an IF statement in there that I was a little iffy about but it seemed like a reasonable thing to do. I'll just go over what's going on here, there is a list of objects to update or add into the database. New objects created in the application are given an ID of 0 while existing objects have their own ID's generated from the DB. If the user chooses to delete some objects, their IDs are stored in a separate list of Integers. Once the user is ready to save their changes, the two lists are passed into this method. By use of the IF statement, objects with ID of 0 are added (using the Add stored procedure) and those objects with non-zero IDs are updated (using the Update stored procedure). After all this, a FOR loop goes through all the integers in the "removal" list and uses the Delete stored procedure to remove them. A transaction is used for all this. Public Shared Sub UpdateSomethings(ByVal SomethingList As List(Of Something), ByVal RemovalList As List(Of Integer)) Using DBConnection As New SqlConnection(conn) DBConnection.Open() Dim MyTransaction As SqlTransaction MyTransaction = DBConnection.BeginTransaction() Try For Each SomethingItem As Something In SomethingList Using MyCommand As New SqlCommand() MyCommand.Connection = DBConnection If SomethingItem.ID > 0 Then MyCommand.CommandText = "UpdateSomething" Else MyCommand.CommandText = "AddSomething" End If MyCommand.Transaction = MyTransaction MyCommand.CommandType = CommandType.StoredProcedure With MyCommand.Parameters If MyCommand.CommandText = "UpdateSomething" Then .Add("@id", SqlDbType.Int).Value = SomethingItem.ID End If .Add("@stuff", SqlDbType.Varchar).Value = SomethingItem.Stuff End With MyCommand.ExecuteNonQuery() End Using Next For Each ID As Integer In RemovalList Using MyCommand As New SqlCommand("DeleteSomething", DBConnection) MyCommand.Transaction = MyTransaction MyCommand.CommandType = CommandType.StoredProcedure With MyCommand.Parameters .Add("@id", SqlDbType.Int).Value = ID End With MyCommand.ExecuteNonQuery() End Using Next MyTransaction.Commit() Catch ex As Exception MyTransaction.Rollback() 'Exception handling goes here End Try End Using End Sub There are three stored procedures used here as well as some looping so I can see how something can be holding everything up if the list is large enough. Other users can log in to the system at the same time just fine though. I'm using Visual Studio 2008 to debug and am using SQL Server 2000 for the DB.

  • Jquery getJSON populate select menu question...

    - by Scott
    I am populating a select menu with getJSON. I am wondering if there's a way that I can use jQuery's .each function to bring in these values? Surely there must be an easier way to accomplish this...maybe? PHP file: <?php $queryMonth = "SELECT monthID, month FROM months"; $result = $db->query($queryMonth); while($rowMonth = $db->fetch_assoc($result)) : $data[] = $rowMonth; endwhile; echo json_encode($data); ?> The jQuery: $.getJSON('selectMenus.php', function(data){ $("select.month").append("<option value=" + data[0].monthID + ">" + data[0].month + "</option>"); $("select.month").append("<option value=" + data[1].monthID + ">" + data[1].month + "</option>"); $("select.month").append("<option value=" + data[2].monthID + ">" + data[2].month + "</option>"); $("select.month").append("<option value=" + data[3].monthID + ">" + data[3].month + "</option>"); $("select.month").append("<option value=" + data[4].monthID + ">" + data[4].month + "</option>"); $("select.month").append("<option value=" + data[5].monthID + ">" + data[5].month + "</option>"); $("select.month").append("<option value=" + data[6].monthID + ">" + data[6].month + "</option>"); $("select.month").append("<option value=" + data[7].monthID + ">" + data[7].month + "</option>"); $("select.month").append("<option value=" + data[8].monthID + ">" + data[8].month + "</option>"); $("select.month").append("<option value=" + data[9].monthID + ">" + data[9].month + "</option>"); $("select.month").append("<option value=" + data[10].monthID + ">" + data[10].month + "</option>"); $("select.month").append("<option value=" + data[11].monthID + ">" + data[11].month + "</option>"); }); my json output looks like this: [{"monthID":"1","month":"January"},{"monthID":"2","month":"February"},{"monthID":"3","month":"March"},{"monthID":"4","month":"April"},{"monthID":"5","month":"May"},{"monthID":"6","month":"June"},{"monthID":"7","month":"July"},{"monthID":"8","month":"August"},{"monthID":"9","month":"Septemeber"},{"monthID":"10","month":"October"},{"monthID":"11","month":"November"},{"monthID":"12","month":"December"}]

  • WCF web service Data Members defaulting to null

    - by James
    I am new to WCF and created a simple REST service to accept an order object (series of strings from XML file), insert that data into a database, and then return an order object that contains the results. To test the service I created a small web project and send over a stream created from an xml doc. The problem is that even though all of the items in the xml doc get placed into the stream, the service is nullifying some of them when it receives the data. For example lineItemId will have a value but shipment status will show null. I step through the xml creation and verify that all the values are being sent. However, if I clear the datamembers and change the names around, it can work. Any help would be appreciated. This is the interface code [ServiceContract] public interface IShipping { [OperationContract] [WebInvoke(Method = "POST", UriTemplate = "/Orders/UpdateOrderStatus/", BodyStyle=WebMessageBodyStyle.Bare)] ReturnOrder UpdateOrderStatus(Order order); } [DataContract] public class Order { [DataMember] public string lineItemId { get; set; } [DataMember] public string shipmentStatus { get; set; } [DataMember] public string trackingNumber { get; set; } [DataMember] public string shipmentDate { get; set; } [DataMember] public string delvryMethod { get; set; } [DataMember] public string shipmentCarrier { get; set; } } [DataContract] public class ReturnOrder { [DataMember(Name = "Result")] public string Result { get; set; } } This is what I'm using to send over an Order object: string lineId = txtLineItem.Text.Trim(); string status = txtDeliveryStatus.Text.Trim(); string TrackingNumber = "1x22-z4r32"; string theMethod = "Ground"; string carrier = "UPS"; string ShipmentDate = "04/27/2010"; XNamespace nsOrders = "http://tempuri.org/order"; XElement myDoc = new XElement(nsOrders + "Order", new XElement(nsOrders + "lineItemId", lineId), new XElement(nsOrders + "shipmentStatus", status), new XElement(nsOrders + "trackingNumber", TrackingNumber), new XElement(nsOrders + "delvryMethod", theMethod), new XElement(nsOrders + "shipmentCarrier", carrier), new XElement(nsOrders + "shipmentDate", ShipmentDate) ); HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://localhost:3587/Deposco.svc/wms/Orders/UpdateOrderStatus/"); request.Method = "POST"; request.ContentType = "application/xml"; try { request.ContentLength = myDoc.ToString().Length; StreamWriter sw = new StreamWriter(request.GetRequestStream()); sw.Write(myDoc); sw.Close(); using (HttpWebResponse response = (HttpWebResponse)request.GetResponse()) { StreamReader reader = new StreamReader(response.GetResponseStream()); string responseString = reader.ReadToEnd(); XDocument.Parse(responseString).Save(@"c:\DeposcoSvcWCF.xml"); } } catch (WebException wEx) { Stream errorStream = ((HttpWebResponse)wEx.Response).GetResponseStream(); string errorMsg = new StreamReader(errorStream).ReadToEnd(); }
