  • ASP.NET Repeater - Evaluate Item as int?

    - by WedTM
    I'm trying to style a table row based upon a value in the databound collection (from LINQ to SQL) in my item template, however it's not working. This is what I have so far: <ItemTemplate> <% string style = String.Empty; if ((string)DataBinder.Eval(Quotes.Cu, "Status") == "Rejected") style = "color:red;"; else if ((string)Eval("Priority") == "Y") style = "color:green;"; if (style == String.Empty) Response.Write("<tr>"); else Response.Write("<tr style=\"" + style + "\""); %> <td> <%# Eval("QuoteID") %> </td> <td> <%# Eval("DateDue", "{0:dd/MM/yyyy}") %> </td> <td> <%# Eval("Company") %> </td> <td> <%# Eval("Estimator") %> </td> <td> <%# Eval("Attachments") %> </td> <td> <%# Eval("Employee") %> </td> </tr> </ItemTemplate>

  • create board for game with events support in WPF

    - by netmajor
    How can I create board for simple game, looks like for chess,but user could dynamically change number of column and rows? In cells I could insert symbol of pawn, like small image or just ellipse or rectangle with fill. This board should have possibility add and remove pawn from cells and move pown from one cell to another. My first idea was Grid. I do it in code behind, but it's hurt to implement events or everything in runtime create board :/ int size = 12; Grid board = new Grid(); board.ShowGridLines = true; for (int i = 0; i < size;i++ ) { board.ColumnDefinitions.Add(new ColumnDefinition()); board.RowDefinitions.Add(new RowDefinition()); } //komputer Rectangle ai = new Rectangle(); ai.Height = 20; ai.Width = 20; ai.AllowDrop = true; ai.Fill = Brushes.Orange; Grid.SetRow(ai, 0); Grid.SetColumn(ai,0); //czlowiek Rectangle hum = new Rectangle(); hum.Height = 20; hum.Width = 20; hum.AllowDrop = true; hum.Fill = Brushes.Green; Grid.SetRow(hum,size); Grid.SetColumn(hum,size); board.Children.Add(ai); board.Children.Add(hum); this.Content = board; It's a way to do this dynamically col and row change in XAML ? It's better way to implement that board create and implement events on move pawn from one cell to another ?

  • Build and test on 2.2.1 iPod Touch with XCode 3.2.2?

    - by slewis
    I've just installed Xcode 3.2.2 with iPhone SDK 3.2 Beta 5 (Snow Leopard) This version of Xcode didn't come with any iPhone SDKs older than 3.0. But I want to create an app that runs on all devices from iPhone OS 2.2.1 - 3.1.3. I managed to add older SDKs into Xcode by downloading iPhone 3.1.3 with Xcode 3.1.4 and installing each 2.x SDK from the 'Packages' folder in the .dmg. So now I can select 2.2.1 as 'iPhone OS Deployment Target' and the 'Base SDK' as 3.1.3, and the app will build (thus letting me use 3.1.3 APIs with conditional coding whilst still running on 2.2.1 devices). But the problem is the app will not install and run on my 2.2.1 iPod Touch. Instead, Xcode tells me 'No provisioned iPhone OS device is connected'. If I bring up the Organizer, in the left column, the iPod Touch has an orange sphere next to it, instead of green, and clicking on this reveals: 'The version of iPhone OS on “iPod touch” is too old for use with this version of the iPhone SDK. Please restore the device to a version of the OS listed below' I'm not sure how to get this version of the SDK to support 2.2.1. (It needs to be this download of XCode/iPhone SDK because I also want it to be a universal binary so it runs on the iPad with a minimum of fuss).

  • How can I make keyword order more relevant in my search?

    - by Atomiton
    In my database, I have a keywords field that stores a comma-delimited list of keywords. For example, a Shrek doll might have the following keywords: ogre, green, plush, hero, boys' toys A "Beanie Baby" doll ( that happens to be an ogre ) might have: beanie baby, kids toys, beanbag toys, soft, infant, ogre (That's a completely contrived example.) What I'd like to do is if the consumer searches for "ogre" I'd like the "Shrek" doll to come up higher in the search results. My content administrator feels that if the keyword is earlier in the list, it should get a higher ranking. ( This makes sense to me and it makes it easy for me to let them control the search result relevance ). Here's a simplified query: SELECT p.ProductID AS ContentID , p.ProductName AS Title , p.ProductCode AS Subtitle , 100 AS Rank , p.ProductKeywords AS Keywords FROM Products AS p WHERE FREETEXT( p.ProductKeywords, @SearchPredicate ) I'm thinking something along the lines of replacing the RANK with: , 200 - INDEXOF(@SearchTerm) AS Rank This "should" rank the keyword results by their relevance I know INDEXOF isn't a SQL command... but it's something LIKE that I would like to accomplish. Am I approaching this the right way? Is it possible to do something like this? Does this make sense?

  • Dynamically add data stored in php to nested json

    - by HoGo
    I am trying to dynamicaly generate data in json for jQuery gantt chart. I know PHP but am totally green with JavaScript. I have read dozen of solutions on how dynamicaly add data to json, and tried few dozens of combinations and nothing. Here is the json format: var data = [{ name: "Sprint 0", desc: "Analysis", values: [{ from: "/Date(1320192000000)/", to: "/Date(1322401600000)/", label: "Requirement Gathering", customClass: "ganttRed" }] },{ name: " ", desc: "Scoping", values: [{ from: "/Date(1322611200000)/", to: "/Date(1323302400000)/", label: "Scoping", customClass: "ganttRed" }] }, <!-- Somoe more data--> }]; now I have all data in php db result. Here it goes: $rows=$db->fetchAllRows($result); $rowsNum=count($rows); And this is how I wanted to create json out of it: var data=''; <?php foreach ($rows as $row){ ?> data['name']="<?php echo $row['name'];?>"; data['desc']="<?php echo $row['desc'];?>"; data['values'] = {"from" : "/Date(<?php echo $row['from'];?>)/", "to" : "/Date(<?php echo $row['to'];?>)/", "label" : "<?php echo $row['label'];?>", "customClass" : "ganttOrange"}; } However this does not work. I have tried without loop and replacing php variables with plain text just to check, but it did not work either. Displays chart without added items. If I add new item by adding it to the list of values, it works. So there is no problem with the Gantt itself or paths. Based on all above I assume the problem is with adding plain data to json. Can anyone please help me to fix it?

  • Matab - Trace contour line between two different points

    - by Graham
    Hi, I have a set of points represented as a 2 row by n column matrix. These points make up a connected boundary or edge. I require a function that traces this contour from a start point P1 and stop at an end point P2. It also needs to be able trace the contour in a clockwise or anti-clockwise direction. I was wondering if this can be achieved by using some of matlabs functions. I have tried to write my own function but this was riddled with bugs and I have also tried using bwtraceboundary and indexing however this has problematic results as the points within the matrix are not in the order that create the contour. Thank you in advance for any help. Btw, I have included a link to a plot of the set of points. It is half the outline of a hand. The function would ideally trace the contour from ether the red star to the green triangle. Returning the points in order of traversal.

  • SQL Server problems reading columns with a foreign key

    - by illdev
    I have a weird situation, where simple queries seem to never finish for instance SELECT top 100 ArticleID FROM Article WHERE ProductGroupID=379114 returns immediately SELECT top 1000 ArticleID FROM Article WHERE ProductGroupID=379114 never returns SELECT ArticleID FROM Article WHERE ProductGroupID=379114 never returns SELECT top 1000 ArticleID FROM Article returns immediately By 'returning' I mean 'in query analyzer the green check mark appears and it says "Query executed successfully"'. I sometimes get the rows painted to the grid in qa, but still the query goes on waiting for my client to time out - 'sometimes': SELECT ProductGroupID AS Product23_1_, ArticleID AS ArticleID1_, ArticleID AS ArticleID18_0_, Inventory_Name AS Inventory3_18_0_, Inventory_UnitOfMeasure AS Inventory4_18_0_, BusinessKey AS Business5_18_0_, Name AS Name18_0_, ServesPeople AS ServesPe7_18_0_, InStock AS InStock18_0_, Description AS Descript9_18_0_, Description2 AS Descrip10_18_0_, TechnicalData AS Technic11_18_0_, IsDiscontinued AS IsDisco12_18_0_, Release AS Release18_0_, Classifications AS Classif14_18_0_, DistributorName AS Distrib15_18_0_, DistributorProductCode AS Distrib16_18_0_, Options AS Options18_0_, IsPromoted AS IsPromoted18_0_, IsBulkyFreight AS IsBulky19_18_0_, IsBackOrderOnly AS IsBackO20_18_0_, Price AS Price18_0_, Weight AS Weight18_0_, ProductGroupID AS Product23_18_0_, ConversationID AS Convers24_18_0_, DistributorID AS Distrib25_18_0_, type AS Type18_0_ FROM Article AS articles0_ WHERE (IsDiscontinued = '0') AND (ProductGroupID = 379121) shows this behavior. I have no idea what is going on. Probably select is broken ;) I got a foreign key on ProductGroups ALTER TABLE [dbo].[Article] WITH CHECK ADD CONSTRAINT [FK_ProductGroup_Articles] FOREIGN KEY([ProductGroupID]) REFERENCES [dbo].[ProductGroup] ([ProductGroupID]) GO ALTER TABLE [dbo].[Article] CHECK CONSTRAINT [FK_ProductGroup_Articles] there are some 6000 rows and IsDiscontinued is a bit, not null, but leaving this condition out does not change the outcome. Anyone can tell me how to handle such a situation? More info, anyone? Additional Info: this does not seem to be restricted to this Foreign Key, but all/some referencing this entity.

  • Deserialize json with json.net c#

    - by 76mel
    Hi, am new to Json so a little green. I have a Rest Based Service that returns a json string; {"treeNode":[{"id":"U-2905","pid":"R","userId":"2905"}, {"id":"U-2905","pid":"R","userId":"2905"}]} I have been playing with the Json.net and trying to Deserialize the string into Objects etc. I wrote an extention method to help. public static T DeserializeFromJSON<T>(this Stream jsonStream, Type objectType) { T result; using (StreamReader reader = new StreamReader(jsonStream)) { JsonSerializer serializer = new JsonSerializer(); try { result = (T)serializer.Deserialize(reader, objectType); } catch (Exception e) { throw; } } return result; } I was expecting an array of treeNode[] objects. But its seems that I can only deserialize correctly if treeNode[] property of another object. public class treeNode { public string id { get; set; } public string pid { get; set; } public string userId { get; set; } } I there a way to to just get an straight array from the deserialization ? Cheers

  • How to traverse table in Jquery and add a class?

    - by SWL
    I have a simple table of two rows. The first column is required, but the others are not; however, I would like them to be required in pairs. So if the user enters a value for Quantity3, then Size3 should also now be required. As a fiddle: http://jsfiddle.net/NaRts/7/ <tr> <td><input name="qty1[492]" class="qty required" type="text"></td> <td><input name="qty2[492]" class="qty" type="text"></td> <td><input name="qty3[492]" class="qty" type="text"></td> </tr><tr> <td><input name="size1[492]" type="text" class="size required" ></td> <td><input name="size2[492]" type="text" class="size" ></td> <td><input name="size3[492]" type="text" class="size" ></td> </tr> And the simple jQuery I have is: $('.qty').keyup(function() { var s = $(this).attr('name'); // = qty3[418] var qtyID = s.replace(/[^1-9\[\]]/g, ""); // = 3[418] var SizeID = "size" + qtyID; var $sizeInput = $(this).closest('tr').next().find(SizeID); $sizeInput.css('background-color', 'green'); $sizeInput.addClass('required'); //I tried this too but it didn't work //$(this).parent().find(SizeID).addClass('required'); });? ? Any help is much appreciated.

  • How to change button background color depending on bound command canexecute ??

    - by LaurentH
    Hi, I Have a ItemTemplate in which is a simple button bound on a command, which can be executable or not depending on some property. I'd like the color of this button's background to change if the command isn't executable. I tried several methods, but I can't find anyway to do this purely in XAML (I'm doing this in a study context, and code behind isn't allowed). Here's my code for the button : <Button x:Name="Dispo" HorizontalAlignment="Center" Margin="0" VerticalAlignment="Center" Width="30" Height="30" Grid.Column="2" Grid.Row="0" Command="{Binding AddEmpruntCommandModel.Command}" CommandParameter="{Binding ElementName='flowCars', Path='SelectedItem'}" vm:CreateCommandBinding.Command="{Binding AddEmpruntCommandModel}" > <Button.Style> <Style TargetType="{x:Type Button}"> <Style.Triggers> <Trigger Property="IsEnabled" Value="True"> <Setter Property="Button.Background" Value="Green"/> </Trigger> <Trigger Property="IsEnabled" Value="False"> <Setter Property="Button.Background" Value="Red"/> </Trigger> </Style.Triggers> </Style> </Button.Style> </Button>

  • how to create static line in coreplot

    - by Rémi Bédard-Couture
    I am trying to make my control lines static so instead of being displayed as part of the graph(the control lines are moving with the graph), they would be displayed like an axis the app can only scroll horizontally i'm talking about the two red line and the green line(which i put over the x axis) this is how i do my lines: // Center line CPTScatterPlot *centerLinePlot = [[CPTScatterPlot alloc] init]; centerLinePlot.identifier = kCenterLine; CPTMutableLineStyle *lineStyle = [CPTMutableLineStyle lineStyle]; lineStyle.lineWidth = 2.0; lineStyle.lineColor = [CPTColor greenColor]; centerLinePlot.dataLineStyle = lineStyle; centerLinePlot.dataSource = self; [graph addPlot:centerLinePlot]; but maybe it has something to do with the displayed range: ////////ajuste la portion a voir if(data.Resultats.count>10) { plotSpace.xRange = [CPTPlotRange plotRangeWithLocation:CPTDecimalFromDouble(data.Resultats.count - 10) length:CPTDecimalFromDouble(10)]; } plotSpace.yRange = [CPTPlotRange plotRangeWithLocation:CPTDecimalFromDouble(RangeMin) length:CPTDecimalFromDouble(RangeMax-RangeMin)]; // Adjust visible ranges so plot symbols along the edges are not clipped CPTMutablePlotRange *xRange = [plotSpace.xRange mutableCopy]; CPTMutablePlotRange *yRange = [plotSpace.yRange mutableCopy]; //place l'axe x sur la ligne de controle pour voir les WorkOrders x.orthogonalCoordinateDecimal = CPTDecimalFromDouble(center); //x.orthogonalCoordinateDecimal = yRange.location; //y.orthogonalCoordinateDecimal = xRange.location; //x.visibleRange = xRange; //y.visibleRange = yRange; //x.gridLinesRange = yRange; //y.gridLinesRange = xRange; [xRange expandRangeByFactor:CPTDecimalFromDouble(1.15)];//1.05 [yRange expandRangeByFactor:CPTDecimalFromDouble(1.15)]; plotSpace.xRange = xRange; plotSpace.yRange = yRange;

  • Firefox adding padding to first image in multiple images, although all images have same styling and size.

  • Linq and returning types

    - by cdotlister
    My GUI is calling a service project that does some linq work, and returns data to my GUI. However, I am battling with the return type of the method. After some reading, I have this as my method: public static IEnumerable GetDetailedAccounts() { IEnumerable accounts = (from a in Db.accounts join i in Db.financial_institution on a.financial_institution.financial_institution_id equals i.financial_institution_id join acct in Db.z_account_type on a.z_account_type.account_type_id equals acct.account_type_id orderby i.name select new {account_id = a.account_id, name = i.name, description = acct.description}); return accounts; } However, my caller is battling a bit. I think I am screwing up the return type, or not handling the caller well, but it's not working as I'd hoped. This is how I am attempting to call the method from my GUI. IEnumerable accounts = Data.AccountService.GetDetailedAccounts(); Console.ForegroundColor = ConsoleColor.Green; Console.WriteLine("Accounts:"); Console.ForegroundColor = ConsoleColor.White; foreach (var acc in accounts) { Console.WriteLine(string.Format("{0:00} {1}", acc.account_id, acc.name + " " + acc.description)); } int accountid = WaitForKey(); However, my foreach, and the acc - isn't working. acc doesn't know about the name, description and id that I setup in the method. Am I at least close to being right?

  • javascript split() array contains

    - by Mahesha999
    While learning JavaScript, I did not get why the output when we print the array returned of the Sting.split() method (with regular expression as an argument) is as explained below. var colorString = "red,blue,green,yellow"; var colors = colorString.split(/[^\,]+/); document.write(colors); //this print 7 times comma: ,,,,,,, However when I print individual element of the array colors, it prints an empty string, three commas and an empty string: document.write(colors[0]); //empty string document.write(colors[1]); //, document.write(colors[2]); //, document.write(colors[3]); //, document.write(colors[4]); //empty string document.write(colors[5]); //undefined document.write(colors[6]); //undefined Then, why printing the array directly gives seven commas. Though I think its correct to have three commas in the second output, I did not get why there is a starting (at index 0) and ending empty string (at index 4). Please explain I am screwed up here.

  • jquery selecting all elements except the last per group

    I have a table that looks like: <table> <tr> <td>one</td><td>two</td><td>three</td><td>last</td> </tr> <tr> <td>blue</td><td>red</td><td>green</td><td>last</td> </tr> <tr> <td>Monday</td><td>Tuesday</td><td>Wednesday</td><td>last</td> </tr> </table> What I want is a jquery selector that will choose all but the last td of each table row. I tried: $("tr td:not(:last)").css("background-color","red"); //changing color just as a test... But instead of all cells but the last on each row being changed, all cells but the very last one in the table are selected. Similarly, if I change it to: $("tr td:last").css("background-color","red"); the only one that changes is the very last cell. How do I choose the last (or not last) of each row?

  • How do I add mouseClicked event to a swing table?

    - by Ayelet
    Hi, I am a new, terribly green user of Swing. I managed to create a table class using examples from java.sun tutorials, and I managed to load data dynamically into it. I want to be able to react to a click on a row by displaying a dialog box. How do I add the event Handler that will identify the selected row number? The main function code: public static void main(String[] args) { javax.swing.SwingUtilities.invokeLater(new Runnable() { public void run() { try { MainWindow window = new MainWindow(); window.frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //Create and set up the content pane. createAndShowGUI(); //... and: private static void createAndShowGUI() { //Create and set up the window. JFrame frame = new JFrame("Data Table"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //Create and set up data of the content pane. TableClass mainTable = new TableClass(fh.getColNames(), fh.getTableContent()); mainTable.setOpaque(true); frame.setContentPane(mainTable); //Display the window. frame.pack(); frame.setVisible(true); } Thank you

  • Objective-C properties are not being recognized in header file?

    Hey folks, I wonder if I'm doing something completely stupid here... I'm clearly missing something. I've gotten used to the pattern of defining properties of a custom class, however I seem to be hitting a point where extended classes do not recognize new properties. Case of point, here's my header file: import import "MyTableViewController.h" @interface MyRootController : MyTableViewController { NSMutableArray *sectionList; } @property (nonatomic, retain) NSMutableArray *sectionList; @end Now, for some reason that "sectionList" property is not turning green within my interface file (ie: it's not being recognized as custom property it seems). As a result, I'm getting all kinds of errors down in my implementation. The first is right at the top of my implementation where I try to synthesize the property: import "MyRootController.h" @implementation MyRootController @synthesize sectionList; That synthesize line throws the error "No declaration of property 'sectionList' found in the interface". So, this is really confusing. I'm clearly doing something wrong, although I can't put my finger on what. One thought: I am extending another custom class of my own. Do I need to specify some kind of super-class declaration to keep the architecture from getting sealed one level up? Thanks!

  • UINavigationController not working under ARC in iPhone

    - by user1811427
    I have creared a new project "Empty Application" template in Xcode 4.3, it is having only two classes AppDelegate.h & .m I cheaked with ARC to use automatic reference count while creating the app. I added two new files "RootViewController" & "NewProjectViewControllers". I implemented code to set navigation controller as follows in AppDelegate - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; // Override point for customization after application launch. rootViewController = [[MainViewController alloc] init]; UINavigationController *navigation = [[UINavigationController alloc] initWithRootViewController:rootViewController]; [self.window addSubview:navigation.view]; self.window.backgroundColor = [UIColor whiteColor]; [self.window makeKeyAndVisible]; return YES; } and in hte home view (Root view controller) implemented as follows - (void)viewDidLoad { [super viewDidLoad]; self.title = @"Projects"; UINavigationBar *navigationBar = [self.navigationController navigationBar]; [navigationBar setTintColor: [UIColor colorWithRed:10/255.0f green:21/255.0f blue:51/255.0f alpha:1.0f]]; //To set the customised bar item UIButton *rightBarBtn = [UIButton buttonWithType:UIButtonTypeCustom]; [rightBarBtn setBackgroundImage:[UIImage imageNamed:@"plus_new.png"] forState:UIControlStateNormal]; rightBarBtn.frame=CGRectMake(0.0, 100.0, 30.0, 30.0); [rightBarBtn addTarget:self action:@selector(addProject) forControlEvents:UIControlEventTouchUpInside]; UIBarButtonItem* rightBarItem = [[UIBarButtonItem alloc] initWithCustomView:rightBarBtn]; self.navigationItem.rightBarButtonItem = rightBarItem; // Do any additional setup after loading the view from its nib. } - (void) addProject { NewProjViewController *editProject = [[NewProjViewController alloc] init]; [self.navigationController pushViewController:editProject animated:YES]; NSLog(@"xxxxxxxxxxxxxxx"); } But since i used ARC the navigation may dealoc immediately and it doesn't work, All the actions in method works except push to the next view if i do same thing with out ARC it works fine How to resolve this issue..? Thanks in advance
