  • iOS App with OCMaps crashes when using the phone in chinese Language

    - by Pedro Morte Rolo
    I've been given the task of doing maintenance to a iOS application that uses OCMapView. I have just realized that when using the application in chinese language, it blows up when the selector doClustering is invoked on a OCMapView instance. This is for me a very puzzling behaviour, because I thought that regardless of the environment language, the OCMapView class should allways have the same methods. Am I wrong? Do you have any recomentations about how to find a solution to this problem? Thank you, Pedro

  • Help with storing/accessing user access roles C# Winforms

    - by user222453
    Hello, firstly I would like to thank you in advance for any assistance provided. I am new to software development and have designed several Client/Server applications over the last 12 months or so, I am currently working on a project that involves a user logging in to gain access to the application and I am looking at the most efficient and "simple" method of storing the users permissions once logged in to the application which can be used throughout restricting access to certain tabs on the main form. I have created a static class called "User" detailed below: static class User { public static int _userID; public static string _moduleName; public static string _userName; public static object[] UserData(object[] _dataRow) { _userID = (int)_dataRow[0]; _userName = (string)_dataRow[1]; _moduleName = (string)_dataRow[2]; return _moduleName; } } When the user logs in and they have been authenticated, I wish to store the _moduleName objects in memory so I can control which tabs on the main form tab control they can access, for example; if the user has been assigned the following roles in the database: "Sales Ledger", "Purchase Ledger" they can only see the relevant tabs on the form, by way of using a Switch - Case block once the login form is hidden and the main form is instantiated. I can store the userID and userName variables in the main form once it loads by means of say for example: Here we process the login data from the user: DataAccess _dal = new DataAccess(); switch (_dal.ValidateLogin(txtUserName.Text, txtPassword.Text)) { case DataAccess.ValidationCode.ConnectionFailed: MessageBox.Show("Database Server Connection Failed!"); break; case DataAccess.ValidationCode .LoginFailed: MessageBox.Show("Login Failed!"); _dal.RecordLogin(out errMsg, txtUserName.Text, workstationID, false); break; case DataAccess.ValidationCode .LoginSucceeded: frmMain frmMain = new frmMain(); _dal.GetUserPrivList(out errMsg,2); //< here I access my DB and get the user permissions based on the current login. frmMain.Show(); this.Hide(); break; default: break; } private void frmMain_Load(object sender, EventArgs e) { int UserID = User._userID; } That works fine, however the _modules object contains mutiple permissions/roles depending on what has been set in the database, how can I store the multiple values and access them via a Switch-Case block? Thank you again in advance.

  • Need an end of lexical scope action which can die normally

    - by Schwern
    I need the ability to add actions to the end of a lexical block where the action might die. And I need the exception to be thrown normally and be able to be caught normally. Unfortunately, Perl special cases exceptions during DESTROY both by adding "(in cleanup)" to the message and making them untrappable. For example: { package Guard; use strict; use warnings; sub new { my $class = shift; my $code = shift; return bless $code, $class; } sub DESTROY { my $self = shift; $self->(); } } use Test::More tests => 2; my $guard_triggered = 0; ok !eval { my $guard = Guard->new( #line 24 sub { $guard_triggered++; die "En guarde!" } ); 1; }, "the guard died"; is $@, "En guarde! at $@ line 24\n", "with the right error message"; is $guard_triggered, 1, "the guard worked"; I want that to pass. Currently the exception is totally swallowed by the eval. This is for Test::Builder2, so I cannot use anything but pure Perl. The underlying issue is I have code like this: { $self->setup; $user_code->(); $self->cleanup; } That cleanup must happen even if the $user_code dies, else $self gets into a weird state. So I did this: { $self->setup; my $guard = Guard->new(sub { $self->cleanup }); $user_code->(); } The complexity comes because the cleanup runs arbitrary user code and it is a use case where that code will die. I expect that exception to be trappable and unaltered by the guard. I'm avoiding wrapping everything in eval blocks because of the way that alters the stack.

    I am programming a GUI with Qt. In my GUI I have a huge std::map. And "MyType" is a class that has different kinds of filds. So, in a word, I want to serialize the std::map. How can I do that? Does Qt provides us with neccesary features? P.S. I would like to use std::map, NOT QMap.

  • Best practice: How to use (repeat) CSS style attributes correctly?

    - by ellie
    Hi guys! As a CSS newbie I'm wondering if it's recommended by professionals to repeat specific style attributes and their not inherited but default properties for every relevant selector? For example, should I rather use body {background:transparent none no-repeat; border:0 none transparent; margin:0; padding:0;} img {background:transparent none no-repeat; border:0 none transparent; margin:0; outline:transparent none 0; padding:0;} div#someID {background:transparent none no-repeat; border:0 none; margin:0 auto; padding:0; text-align:left; width:720px; ...} or body {background:transparent; border:0; margin:0; padding:0;} img {background:transparent; border:0; margin:0; outline:0; padding:0;} div#someID {background:transparent; border:0; margin:0 auto; padding:0; text-align:left; width:720px; ...} or just what (I think) I really need body {background:transparent; margin:0; padding:0;} img {border:0; outline:0;} div#someID {margin:0 auto; width:720px; ...} If it's best practice to go with the first or second one what do you think about defining a class like .foo {background:transparent; border:0; margin:0; padding:0;} and then applying it to every relevant selector: <div id="someID" class="foo">...</div> Yep, now I'm totally confused... so please advise! Thanks!

    Hi We are looking into using the JdbcTemplate for accessing the DB - but we have many different DB-connections, that each class could use, so injecting the jdbcTemplate is not an option atm. So if we do a jdbcTemplate = new JdbcTemplate(dataSource); what will the transaction policy be? Auto-commit is off in the DB.

  • 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(); }

I would like to the following: print x.features(0).size I am aware that it is possible to create and instance from an existent class, but that is not what I want for this particular scenario.

  • Are there any "undocumented features" in Silverlight?

    - by Sorskoot
    I was wondering if there are any features in Silverlight 2 or 3 that aren't documented or are hidden very deep in the framework? Stuff that can be very helpful in some cases, but can be a pain to find. Are there any "hidden" gems? I'm thinking about stuff you normaly don't find in tutorials and in demos. For example, finding information about the operating system the Silverlight Application is running on thru the System.OperatingSystem class.

    Im reading in 2 csv file: store_inventory & new_acquisitions... I want to be able to compare the store_inventory csv file with new_acquisitions. 1) If the item names match just update the quantity in store_inventory. 2) If new_acquisitions has a new item that does not exist in store_inventory, then add it to the store_inventory. Heres what i have so far but its not very good. I added comments where i need to add taks 1) & 2). Any advice or code would be great, thanks.
