  • I am getting duplicates in UITableView, cellForRowAtIndexPath

    - by Martol1ni
    I am getting duplicates of my array, and wrongly displayed cells in this method: Here I am initializing the array, and adding it to the tableView: NSArray *sectionsArray = [NSArray arrayWithObjects: @"Location", @"Front Post", @"Front Fixing", @"Front Footplate", @"Rear Post", @"Read Fixing", @"Rear Footplate", @"Horizontal Bracing", @"Diagonal Bracing", @"Front Beam", @"Front Lock", @"Rear Beam", @"Rear Lock", @"Guard", @"Accessories", @"Comments", @"Off load ref", @"Loc Empty", @"Loc Affected", nil]; [_tableArray setObject:sectionsArray atIndexedSubscript:2]; [_tableView reloadData]; For some weird reason there are always the 4th object that is messed up, and is either duplicated, or do not have the views from IB. Here is the cellForRowAtIndexPath: method: - (UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell; if (indexPath.section == 2) { cell = [tableView dequeueReusableCellWithIdentifier:@"EntryCell"]; cell.tag = indexPath.row; UILabel *label = (UILabel *)[cell viewWithTag:3]; [label setText:[[_tableArray objectAtIndex:2] objectAtIndex:indexPath.row]]; } return cell; } I have logged the string [[_tableArray objectAtIndex:2] objectAtIndex:indexPath.row], and it logs the right string.

  • boolean in java: what am I doing wrong?

    - by Cheesegraterr
    Hello, I am trying to make my boolean value work. I am new at programming java so I must be missing something simple. I am trying to make it so that if one of the tire pressures is below 35 or over 45 the system outputs "bad inflation" For class me must use a boolean which is what I tried. I cant figure out why this isnt working. No matter what I do the boolean is always true. Any tips? public class tirePressure { private static double getDoubleSystem1 () //Private routine to simply read a double in from the command line { String myInput1 = null; //Store the string that is read form the command line double numInput1 = 0; //Used to store the converted string into an double BufferedReader mySystem; //Buffer to store input mySystem = new BufferedReader (new InputStreamReader (System.in)); // creates a connection to system files or cmd try { myInput1 = mySystem.readLine (); //reads in data from console myInput1 = myInput1.trim (); //trim command cuts off unneccesary inputs } catch (IOException e) //checks for errors { System.out.println ("IOException: " + e); return -1; } numInput1 = Double.parseDouble (myInput1); //converts the string to an double return numInput1; //return double value to main program } static public void main (String[] args) { double TireFR; //double to store input from console double TireFL; double TireBR; double TireBL; boolean goodPressure; goodPressure = false; System.out.println ("Tire Pressure Checker"); System.out.println (" "); System.out.print ("Enter pressure of front left tire:"); TireFL = getDoubleSystem1 (); //read in an double from the user if (TireFL < 35 || TireFL > 45) { System.out.println ("Pressure out of range"); goodPressure = false; } System.out.print ("Enter pressure of front right tire:"); TireFR = getDoubleSystem1 (); //read in an double from the user if (TireFR < 35 || TireFR > 45) { System.out.println ("Pressure out of range"); goodPressure = false; } if (TireFL == TireFR) System.out.print (" "); else System.out.println ("Front tire pressures do not match"); System.out.println (" "); System.out.print ("Enter pressure of back left tire:"); TireBL = getDoubleSystem1 (); //read in an double from the user if (TireBL < 35 || TireBL > 45) { System.out.println ("Pressure out of range"); goodPressure = false; } System.out.print ("Enter pressure of back right tire:"); TireBR = getDoubleSystem1 (); //read in an double from the user if (TireBR < 35 || TireBR > 45) { System.out.println ("Pressure out of range"); goodPressure = false; } if (TireBL == TireBR) System.out.print (" "); else System.out.println ("Back tire pressures do not match"); if (goodPressure = true) System.out.println ("Inflation is OK."); else System.out.println ("Inflation is BAD."); System.out.println (goodPressure); } //mainmethod } // tirePressure Class

  • iPhone accelerometer:didAccelerate: seems to not get called while I am running a loop

    - by AJ
    An accelerometer related question. (Sorry the formatting may not look right, its the first time I am using this site). I got the accelerometer working as expected using the standard code UIAccelerometer *accel = [UIAccelerometer sharedAccelerometer]; accel.delegate = self; accel.updateInterval = 0.1; //I also tried other update values I use NSLog to log every time the accelerometer:didAccelerate: method in my class is called. The function gets called as expected and everything works fine till here. However, when I run a loop, the above method doesn't seem to get called. Something like this float firstAccelValue = globalAccel; //this is the x-accel value (stored in a global by the above method) float nextAccelValue = firstAccelValue; while (nextAccelValue == firstAccelValue){ //do something nextAccelValue = globalAccel; // note globalAccel is updated by the accelerometer method } The above loop never exits, expectedly since the accelerometer:didAccelerate: method is not getting called, and hence globalAccel never changes value. If I use a fixed condition to break the while loop, I can see that after the loop ends, the method calls work fine again. Am I missing something obvious here? Or does the accelerometer method not fire when certain processing is being done? Any help would be greatly appreciated! Thanks!

  • WHy am I unable to add text along with <%# Container.DataItem %> in repeater in user control

    - by Jamie Hartnoll
    I have a User Control which is dynamically placed by CodeBehind as follows: Dim myControl As Control = CType(Page.LoadControl("~/Controls/mainMenu.ascx"), Control) If InStr(Request.ServerVariables("url"), "/Login.aspx") <= 0 Then mainMenu.Controls.Add(myControl) End If As per an example from my previous question on here. Within this Control is a repeater which calls a database to generate values. My Repeater mark-up is as follows <asp:Repeater runat="server" ID="locationRepeater" OnItemDataBound="getQuestionCount"> <ItemTemplate> <p id='locationQuestions' title='<%# Container.DataItem %>' runat='server'></p> </ItemTemplate> </asp:Repeater> The example above works fine, but I want to be able to prepend text to <%# Container.DataItem %> in the title attribute of that <p to print to the browser like this is some text DATA_ITEM_OUTPUT When I try to do that though, it prints this is some text <%# Container.DataItem %> exactly like that, ie, turning <%# Container.DataItem %> into text, NOT the value from the repeater code. It was working fine before I made it into a dynamically inserted control, so I am thinking I might have something being generated in the wrong order, but given that it works without any prepended text, I am stumped to fix it! I'm new to .net and using vb.net, please could someone point me in the right direction?

  • Poor DB4O performance - What am I doing wrong?

    - by Jon
    I read Rob Conery's post about Object databases and thought I'd give it a go. I have a class lets say Book with 15 properties mostly string, some int, one Datetime and 2 decimals. I used Rob's code to open the database file etc to test on a Winforms project not a Web project. So I did the following: for(int i = 0; i < 1000000; i++) { var Book = new Book(); //Assign variables s.Save(Book); } s.CommitChanges(); This took at least a couple of minutes. I then tried to retrieve all data to test speed: var spp = s.All<Passports>(); This one line was quick, however, then doing: sppp.Count() as well as a seperate test doing a foreach loop and incrementing a counter took a couple of minutes. This seems quite slow to me. Am I doing something wrong or am I expecting too much?

  • I am looking for an actual functional web browser control for .NET, maybe a C++ library

    - by Joshua
    I am trying to emulate a web browser in order to execute JavaScript code and then parse the DOM. The System.Windows.Forms.WebBrowser object does not give me the functionality I need. It let's me set the headers, but you cannot set the proxy or clear cookies. Well you can, but it is not ideal and messes with IE's settings. I've been extending the WebBrowser control pinvoking native windows functions so far, but it is really one hack on top of another. I can mess with the proxy and also clear cookies and such, but this control has its issues as I mentioned. I found something called WebKit .NET (http://webkitdotnet.sourceforge.net/), but I don't see support for setting proxies or cookie manipulation. Can someone recommend a c++/.NET/whatever library to do this: Basically tell me what I need to do to get an interface to similar this in .NET: // this should probably pause the current thread for the max timeout, // throw an exception on failure or return null w/e, VAGUELY similar to this string WebBrowserEmu::FetchBrowserParsedHtml(Uri url, WebProxy p, int timeoutSeconds, byte[] headers, byte[] postdata); void WebBrowserEmu::ClearCookies(); I am not responsible for my actions.

  • I am confused about how to use @SessionAttributes

    - by yusaku
    I am trying to understand architecture of Spring MVC. However, I am completely confused by behavior of @SessionAttributes. Please look at SampleController below , it is handling post method by SuperForm class. In fact, just field of SuperForm class is only binding as I expected. However, After I put @SessionAttributes in Controller, handling method is binding as SubAForm. Can anybody explain me what happened in this binding. ------------------------------------------------------- @Controller @SessionAttributes("form") @RequestMapping(value = "/sample") public class SampleController { @RequestMapping(method = RequestMethod.GET) public String getCreateForm(Model model) { model.addAttribute("form", new SubAForm()); return "sample/input"; } @RequestMapping(method = RequestMethod.POST) public String register(@ModelAttribute("form") SuperForm form, Model model) { return "sample/input"; } } ------------------------------------------------------- public class SuperForm { private Long superId; public Long getSuperId() { return superId; } public void setSuperId(Long superId) { this.superId = superId; } } ------------------------------------------------------- public class SubAForm extends SuperForm { private Long subAId; public Long getSubAId() { return subAId; } public void setSubAId(Long subAId) { this.subAId = subAId; } } ------------------------------------------------------- <form:form modelAttribute="form" method="post"> <fieldset> <legend>SUPER FIELD</legend> <p> SUPER ID:<form:input path="superId" /> </p> </fieldset> <fieldset> <legend>SUB A FIELD</legend> <p> SUB A ID:<form:input path="subAId" /> </p> </fieldset> <p> <input type="submit" value="register" /> </p> </form:form>

  • What am I missing about WCF?

    - by Bigtoe
    I've been developing in MS technologies for longer than I care to remember at this stage. When .NET arrived on the scene I thought they hit the nail on the head and with each iteration and version I thought their technologies were getting stronger and stronger and looked forward to each release. However, having had to work with WCF for the last year I must say I found the technology very difficult to work with and understand. Initially it's quite appealing but when you start getting into the guts of it, configuration is a nightmare, having to override behaviours for message sizes, number of objects contained in a messages, the complexity of the security model, disposing of proxies when faulted and finally moving back to defining interfaces in code rather than in XML. It just does not work out of the box and I think it should. We found all of the above issues while either testing ourselves or else when our products were out on site. I do understand the rationale behind it all, but surely they could have come up with simpler implementation mechanism. I suppose what I'm asking is, Am I looking at WCF the wrong way? What strengths does it have over the alternatives? Under what circumstances should I choose to use WCF? OK Folks, Sorry about the delay in responding, work does have a nasty habbit of get in the way somethimes :) Some clarifications My main paint point with WCF I suppose falls down into the following areas While it does work out of the box, your left with some major surprises under the hood. As pointed out above basic things are restricted until they are overridden Size of string than can be passed can't be over 8K Number of objects that can be passed in a single message is restricted Proxies not automatically recovering from failures The amount of configuration while it's there is a good thing, but understanding it all and what to use what and under which circumstances can be difficult to understand. Especially when deploying software on site with different security requirements etc. When talking about configuration, we've had to hide lots of ours in a back-end database because security and network people on-site were trying to change things in configuration files without understanding it. Keeping the configuration of the interfaces in code rather than moving to explicitly defined interfaces in XML, which can be published and consumed by almost anything. I know we can export the XML from the assembley, but it's full of rubbish and certain code generators choke on it. I know the world moves on, I've moved on a number of times over the last (ahem 22 years I've been developing) and am actively using WCF, so don't get me wrong, I do understand what it's for and where it's heading. I just think there should be simplier configuration/deployment options available, easier set-up and better management for configuration (SQL config provider maybe, rahter than just the web.config/app.config files). OK, back to the daily grid. Thanks for all your replies so far. Kind Regards Noel

  • Am I using Settings in C# correctly?

    - by Sergio Tapia
    Here's what I'm doing. I have three properties: MomsBackground, DadsBackground and ChosenBackground. When Momsbackground is selected in the program, I set the ChosenBackground string according to what item the user has clicked (either "Mom" or "Dad"). Then on Form_Load() I use a switch case for the ChosenBackground string and according to that select This.BackgroundColor to MomsBackground or DadsBackground. Code below: Am I using this as it was intended?

  • Am I Leaking ADO.NET Connections?

    - by HardCode
    Here is an example of my code in a DAL. All calls to the database's Stored Procedures are structured this way, and there is no in-line SQL. Friend Shared Function Save(ByVal s As MyClass) As Boolean Dim cn As SqlClient.SqlConnection = Dal.Connections.MyAppConnection Dim cmd As New SqlClient.SqlCommand Try cmd.Connection = cn cmd.CommandType = CommandType.StoredProcedure cmd.CommandText = "proc_save_my_class" cmd.Parameters.AddWithValue("@param1", s.Foo) cmd.Parameters.AddWithValue("@param2", s.Bar) Return True Finally Dal.Utility.CleanupAdoObjects(cmd, cn) End Try End Function Here is the Connection factory (if I am using the correct term): Friend Shared Function MyAppConnection() As SqlClient.SqlConnection Dim cn As New SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings("MyConnectionString").ToString) cn.Open() If cn.State <> ConnectionState.Open Then ' CriticalException is a custom object inheriting from Exception. Throw New CriticalException("Could not connect to the database.") Else Return cn End If End Function Here is the Dal.Utility.CleaupAdoObjects() function: Friend Shared Sub CleanupAdoObjects(ByVal cmd As SqlCommand, ByVal cn As SqlConnection) If cmd IsNot Nothing Then cmd.Dispose() If cn IsNot Nothing AndAlso cn.State <> ConnectionState.Closed Then cn.Close() End Sub I am getting a lot of "Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding." error messages reported by the users. The application's DAL opens a connection, reads or saves data, and closes it. No connections are ever left open - intentionally! There is nothing obvious on the Windows 2000 Server hosting the SQL Server 2000 that would indicate a problem. Nothing in the Event Logs and nothing in the SQL Server logs. The timeouts happen randomly - I cannot reproduce. It happens early in the day with only 1 to 5 users in the system. It also happens with around 50 users in the system. The most connections to SQL Server via Performance Monitor, for all databases, has been about 74. The timeouts happen in code that both saves to, and reads from, the database in different parts of the application. The stack trace does not point to one or two offending DAL functions. It's happened in many different places. Does my ADO.NET code appear to be able to leak connections? I've goolged around a bit, and I've read that if the connection pool fills up, this can happen. However, I'm not explicitly setting any connection pooling. I've even tried to increase the Connection Timeout in the connection string, but timeouts happen long before the 300 second (5 minute) value: <add name="MyConnectionString" connectionString="Data Source=MyServer;Initial Catalog=MyDatabase;Integrated Security=SSPI;Connection Timeout=300;"/> I'm at a total loss already as to what is causing these Timeout issues. Any ideas are appreciated.

  • Am I missing something about LINQ?

    - by Jason Baker
    I seem to be missing something about LINQ. To me, it looks like it's taking some of the elements of SQL that I like the least and moving them into the C# language and using them for other things. I mean, I could see the benefit of using SQL-like statements on things other than databases. But if I wanted to write SQL, well, why not just write SQL and keep it out of C#? What am I missing here?

  • Unit Testing - Am I doing it right?

    - by baron
    Hi everyone, Basically I have been programing for a little while and after finishing my last project can fully understand how much easier it would have been if I'd have done TDD. I guess I'm still not doing it strictly as I am still writing code then writing a test for it, I don't quite get how the test becomes before the code if you don't know what structures and how your storing data etc... but anyway... Kind of hard to explain but basically lets say for example I have a Fruit objects with properties like id, color and cost. (All stored in textfile ignore completely any database logic etc) FruitID FruitName FruitColor FruitCost 1 Apple Red 1.2 2 Apple Green 1.4 3 Apple HalfHalf 1.5 This is all just for example. But lets say I have this is a collection of Fruit (it's a List<Fruit>) objects in this structure. And my logic will say to reorder the fruitids in the collection if a fruit is deleted (this is just how the solution needs to be). E.g. if 1 is deleted, object 2 takes fruit id 1, object 3 takes fruit id2. Now I want to test the code ive written which does the reordering, etc. How can I set this up to do the test? Here is where I've got so far. Basically I have fruitManager class with all the methods, like deletefruit, etc. It has the list usually but Ive changed hte method to test it so that it accepts a list, and the info on the fruit to delete, then returns the list. Unit-testing wise: Am I basically doing this the right way, or have I got the wrong idea? and then I test deleting different valued objects / datasets to ensure method is working properly. [Test] public void DeleteFruit() { var fruitList = CreateFruitList(); var fm = new FruitManager(); var resultList = fm.DeleteFruitTest("Apple", 2, fruitList); //Assert that fruitobject with x properties is not in list ? how } private static List<Fruit> CreateFruitList() { //Build test data var f01 = new Fruit {Name = "Apple",Id = 1, etc...}; var f02 = new Fruit {Name = "Apple",Id = 2, etc...}; var f03 = new Fruit {Name = "Apple",Id = 3, etc...}; var fruitList = new List<Fruit> {f01, f02, f03}; return fruitList; }
