  • jQuery to populate array-named form fields based on first entered value where number of fields is un

    - by da5id
    Greetings, I have a form with a variable number of inputs, a simplified version of which looks like this: <form> <label for="same">all the same as first?</label> <input id="same" name="same" type="checkbox" /> <input type="text" id="foo[1]" name="foo[1]" value="" /> <input type="text" id="foo[2]" name="foo[2]" value="" /> <input type="text" id="foo[3]" name="foo[3]" value="" /> <input type="text" id="foo[4]" name="foo[4]" value="" /> <input type="text" id="foo[5]" name="foo[5]" value="" /> </form> The idea is to tick the #same checkbox and have jQuery copy the value from #foo[1] into #foo[2], #foo[3], etc. They also need to clear if #same is unchecked. There can be any number of #foo inputs, based upon input from a previous stage of the form, and this bit is giving me trouble. I'm sure I'm missing something obvious, but I can't get any variation on $('#dest').val($('#source').val()); to work. Help!

  • Why is ExecuteFunction method only available through base.ExecuteFunction in a child class of Object

    - by Matt
    I'm trying to call ObjectContext.ExecuteFunction from my objectcontext object in the repository of my site. The repository is generic, so all I have is an ObjectContext object, rather than one that actually represents my specific one from the Entity Framework. Here's an example of code that was generated that uses the ExecuteFunction method: [global::System.CodeDom.Compiler.GeneratedCode("System.Data.Entity.Design.EntityClassGenerator", "4.0.0.0")] public global::System.Data.Objects.ObjectResult<ArtistSearchVariation> FindSearchVariation(string source) { global::System.Data.Objects.ObjectParameter sourceParameter; if ((source != null)) { sourceParameter = new global::System.Data.Objects.ObjectParameter("Source", source); } else { sourceParameter = new global::System.Data.Objects.ObjectParameter("Source", typeof(string)); } return base.ExecuteFunction<ArtistSearchVariation>("FindSearchVariation", sourceParameter); } But what I would like to do is something like this... public class Repository<E, C> : IRepository<E, C>, IDisposable where E : EntityObject where C : ObjectContext { private readonly C _ctx; // ... public ObjectResult<E> ExecuteFunction(string functionName, params[]) { // Create object parameters return _ctx.ExecuteFunction<E>(functionName, /* parameters */) } } Anyone know why I have to call ExecuteFunction from base instead of _ctx? Also, is there any way to do something like I've written out? I would really like to keep my repository generic, but with having to execute stored procedures it's looking more and more difficult... Thanks, Matt

  • ISO-8859-1 to UTF8 in ASP.NET 2

    - by Gordon Carpenter-Thompson
    We've got a page which posts data to our ASP.NET app in ISO-8859-1 <head> <META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=iso-8859-1"> <title>`Sample Search Invoker`</title> </head> <body> <form name="advancedform" method="post" action="SearchResults.aspx"> <input class="field" name="SearchTextBox" type="text" /> <input class="button" name="search" type="submit" value="Search &gt;" /> </form> and in the code behind (SearchResults.aspx.cs) System.Collections.Specialized.NameValueCollection postedValues = Request.Form; String nextKey; for (int i = 0; i < postedValues.AllKeys.Length; i++) { nextKey = postedValues.AllKeys[i]; if (nextKey.Substring(0, 2) != "__") { // Get basic search text if (nextKey.EndsWith(XAEConstants.CONTROL_SearchTextBox)) { // Get search text value String sSentSearchText = postedValues[i]; System.Text.Encoding iso88591 = System.Text.Encoding.GetEncoding("iso-8859-1"); System.Text.Encoding utf8 = System.Text.Encoding.UTF8; byte[] abInput = iso88591.GetBytes(sSentSearchText); sSentSearchText = utf8.GetString(System.Text.Encoding.Convert(iso88591, utf8, abInput)); this.SearchText = sSentSearchText.Replace('<', ' ').Replace('>',' '); this.PreviousSearchText.Value = this.SearchText; } } } When we pass through Merkblätter it gets pulled out of postedValues[i] as Merkbl?tter The raw string string is Merkbl%ufffdtter Any ideas?

  • Asp.Net MVC Tutorial Unit Tests

    - by Nicholas
    I am working through Steve Sanderson's book Pro ASP.NET MVC Framework and I having some issues with two unit tests which produce errors. In the example below it tests the CheckOut ViewResult: [AcceptVerbs(HttpVerbs.Post)] public ViewResult CheckOut(Cart cart, FormCollection form) { // Empty carts can't be checked out if (cart.Lines.Count == 0) { ModelState.AddModelError("Cart", "Sorry, your cart is empty!"); return View(); } // Invoke model binding manually if (TryUpdateModel(cart.ShippingDetails, form.ToValueProvider())) { orderSubmitter.SubmitOrder(cart); cart.Clear(); return View("Completed"); } else // Something was invalid return View(); } with the following unit test [Test] public void Submitting_Empty_Shipping_Details_Displays_Default_View_With_Error() { // Arrange CartController controller = new CartController(null, null); Cart cart = new Cart(); cart.AddItem(new Product(), 1); // Act var result = controller.CheckOut(cart, new FormCollection { { "Name", "" } }); // Assert Assert.IsEmpty(result.ViewName); Assert.IsFalse(result.ViewData.ModelState.IsValid); } I have resolved any issues surrounding 'TryUpdateModel' by upgrading to ASP.NET MVC 2 (Release Candidate 2) and the website runs as expected. The associated error messages are: *Tests.CartControllerTests.Submitting_Empty_Shipping_Details_Displays_Default_View_With_Error: System.ArgumentNullException : Value cannot be null. Parameter name: controllerContext* and the more detailed at System.Web.Mvc.ModelValidator..ctor(ModelMetadata metadata, ControllerContext controllerContext) at System.Web.Mvc.DefaultModelBinder.OnModelUpdated(ControllerContext controllerContext, ModelBindingContext bindingContext) at System.Web.Mvc.DefaultModelBinder.BindComplexModel(ControllerContext controllerContext, ModelBindingContext bindingContext) at System.Web.Mvc.Controller.TryUpdateModel[TModel](TModel model, String prefix, String[] includeProperties, String[] excludeProperties, IValueProvider valueProvider) at System.Web.Mvc.Controller.TryUpdateModel[TModel](TModel model, IValueProvider valueProvider) at WebUI.Controllers.CartController.CheckOut(Cart cart, FormCollection form) Has anyone run into a similar issue or indeed got the test to pass?

  • cleaning up noise in an edge detection algoritum

    - by Faken
    I recently wrote an extremely basic edge detection algorithm that works on an array of chars. The program was meant to detect the edges of blobs of a single particular value on the array and worked by simply looking left, right, up and down on the array element and checking if one of those values is not the same as the value it was currently looking at. The goal was not to produce a mathematical line but rather a set of ordered points that represented a descritized closed loop edge. The algorithm works perfectly fine, except that my data contained a bit of noise hence would randomly produce edges where there should be no edges. This in turn wreaked havoc on some of my other programs down the line. There is two types of noise that the data contains. The first type is fairly sparse and somewhat random. The second type is a semi continuous straight line on the x=y axis. I know the source of the first type of noise, its a feature of the data and there is nothing i can do about it. As for the second type, i know it's my program's fault for causing it...though i haven't a hot clue exactly what is causing it. My question is: How should I go about removing the noise completely? I know that the correct data has points that are always beside each other and is very compact and ordered (with no gaps) and is a closed loop or multiple loops. The first type of noise is usually sparse and random, that could be easily taken care of by checking if any edges is next that noise point is also counted as an edge. If not, then the point is most defiantly noise and should be removed. However, the second type of noise, where we have a semi continuous line about x=y poses more of a problem. The line is sometimes continuous for random lengths (the longest was it went half way across my entire array unbroken). It is even possible for it to intersect the actual edge. Any ideas on how to do this?

  • Running job in the background from Perl WITHOUT waiting for return

    - by Rafael Almeida
    The Disclaimer First of all, I know this question (or close variations) have been asked a thousand times. I really spent a few hours looking in the obvious and the not-so-obvious places, but there may be something small I'm missing. The Context Let me define the problem more clearly: I'm writing a newsletter app in which I want the actual sending process to be async. As in, user clicks "send", request returns immediately and then they can check the progress in a specific page (via AJAX, for example). It's written in your traditional LAMP stack. In the particular host I'm using, PHP's exec() and system() are disabled for security reasons, but Perl's system functions (exec, system and backticks) aren't. So my workaround solution was to create a "trigger" script in Perl that calls the actual sender via the PHP CLI, and redirects to the progress page. Where I'm Stuck The very line the calls the sender is, as of now: system("php -q sender.php &"); Problem being, it's not returning immediately, but waiting for the script to finish. I want it to run in the background but the system call itself returns right away. I also tried running a similar script in my Linux terminal, and in fact the prompt doesn't show until after the script has finished, even though my test output doesn't run, indicating it's really running in the background. What I already tried Perl's exec() function - same result of system(). Changing the command to: "php -q sender.php | at now"), hoping that the "at" daemon would return and that the PHP process itself wouldn't be attached to Perl. What should I try now?

  • Parsec: backtracking not working

    - by Nathan Sanders
    I am trying to parse F# type syntax. I started writing an [F]Parsec grammar and ran into problems, so I simplified the grammar down to this: type ::= identifier | type -> type identifier ::= [A-Za-z0-9.`]+ After running into problems with FParsec, I switched to Parsec, since I have a full chapter of a book dedicated to explaining it. My code for this grammar is typeP = choice [identP, arrowP] identP = do id <- many1 (digit <|> letter <|> char '.' <|> char '`') -- more complicated code here later return id arrowP = do domain <- typeP string "->" range <- typeP return $ "("++domain++" -> "++range++")" run = parse (do t <- typeP eof return t) "F# type syntax" The problem is that Parsec doesn't backtrack by default, so > run "int" Right "int" -- works! > run "int->int" Left "F# type syntax" unexpected "-" expecting digit, letter, ".", "`" or end of input -- doesn't work! The first thing I tried was to reorder typeP: typeP = choice [arrowP, identP] But this just stack overflows because the grammar is left-recursive--typeP never gets to trying identP because it keeps trying arrowP over and over. Next I tried try in various places, for example: typeP = choice [try identP, arrowP] But nothing I do seems to change the basic behaviours of (1) stack overflow or (2) non-recognition of "-" following an identifier. My mistake is probably obvious to anybody who has successfully written a Parsec grammar. Can somebody point it out?

  • Iteration speed of int vs long

    - by jqno
    I have the following two programs: long startTime = System.currentTimeMillis(); for (int i = 0; i < N; i++); long endTime = System.currentTimeMillis(); System.out.println("Elapsed time: " + (endTime - startTime) + " msecs"); and long startTime = System.currentTimeMillis(); for (long i = 0; i < N; i++); long endTime = System.currentTimeMillis(); System.out.println("Elapsed time: " + (endTime - startTime) + " msecs"); Note: the only difference is the type of the loop variable (int and long). When I run this, the first program consistently prints between 0 and 16 msecs, regardless of the value of N. The second takes a lot longer. For N == Integer.MAX_VALUE, it runs in about 1800 msecs on my machine. The run time appears to be more or less linear in N. So why is this? I suppose the JIT-compiler optimizes the int loop to death. And for good reason, because obviously it doesn't do anything. But why doesn't it do so for the long loop as well? A colleague thought we might be measuring the JIT compiler doing its work in the long loop, but since the run time seems to be linear in N, this probably isn't the case.

  • Using jQuery, setting Draggable on an element prevents blur from firing when you click the draggable

    - by Danno
    Using jQuery, when you set a blur event on a text box and set another element as draggable, when you click the draggable element, the blur event does not fire in FireFox. IE is a little better, you get the blur event but you don't get the click event on the draggable element. If you don't specify the cancel: "" in the draggable constructor, you will get the blur event to fire, but then the element you want to drag is not draggable. jQuery v1.3.2 jQuery UI v1.7.2 The console.log lines are for FireFox's FireBug plugin. <HTML> <HEAD> <TITLE>Blur/Click Workbench</TITLE> <script src="js/jquery.js" type="text/javascript" ></script> <script src="js/ui/ui.core.js" type="text/javascript"></script> <script src="js/ui/ui.draggable.js" type="text/javascript"></script> <script type="text/javascript"> function blurring() { console.log('1 - blurring - ' + $( this ).attr('id')); } function clicking() { console.log('2 - clicking - ' + $( this ).attr('id')); } $(document).ready(function() { $( ".draggableTool" ).draggable( { cancel: "" } ); $( '.property' ).blur( blurring ); $( '#labelContainer' ).click( clicking ); }); </script> </HEAD> <BODY> <input type='text' class='property' id='tb1' /> <br /> <input type='text' class='property' id='tb2' /> <br /> <label class='draggableTool' id='labelContainer' style='height:20px;position:absolute;'> <textarea id='taLabel' style='height:100%;background-color:white;border:1px solid grey;'>Label</textarea> </label> </BODY> </HTML>

  • Trigger for ComboBox in Silverlight

    - by Budda
    Is there any possibility to display selected item of the ComboBox (after popup closing) in a way that is different from its displaying in DropDown List (There are players number and name in the dropdown list, but after list closing I want to see only its number). How can I change a background for the player with some Flag? As far as I know, all of that can be done with triggers, but are they supported in Silverlight 4, VS2010, Silverlight Toolkit 4? In my case the following code <ComboBox ItemsSource="{Binding PlayersAll}" SelectedItem="{Binding Path=SelectedPlayer, Mode=TwoWay}" > <ComboBox.ItemTemplate> <DataTemplate> <ToolkitControls:WrapPanel Orientation="Horizontal"> <TextBlock Text="{Binding TeamNumber}"/> <TextBlock Text=" - "/> <TextBlock Text="{Binding ShortName}"/> </ToolkitControls:WrapPanel> <DataTemplate.Triggers> <Trigger Property="HasError" Value="True"> <Setter Property="Background" TargetName="FlagSet" Value="Red"/> </Trigger> </DataTemplate.Triggers> </DataTemplate> </ComboBox.ItemTemplate> </ComboBox> gives an error: The property 'Triggers' does not exist on the type 'DataTemplate' in the XML namespace 'http://schemas.microsoft.com/winfx/2006/xaml/presentation' what is wrong here? Here are my namespaces: xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:navigation="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Navigation" xmlns:data="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data" xmlns:ToolkitControls="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Toolkit"

  • Calling unmanaged dll from C#. Take 2

I asked this question to try and solve my problem, but I have modified it my test environment and I think it is worth asking a new question.

    Hello I have tried to do fork() and piping in main and it works perfectly fine but when I try to implement it in a function for some reason I don't get any output, this is my code: void cmd(int **pipefd,int count,int type, int last); int main(int argc, char *argv[]) { int pipefd[3][2]; int i, total_cmds = 3,count = 0; int in = 1; for(i = 0; i < total_cmds;i++){ pipe(pipefd[count++]); cmd(pipefd,count,i,0); } /*Last Command*/ cmd(pipefd,count,i,1); exit(EXIT_SUCCESS); } void cmd(int **pipefd,int count,int type, int last){ int child_pid,i,i2; if ((child_pid = fork()) == 0) { if(count == 1){ dup2(pipefd[count-1][1],1); /*first command*/ } else if(last!=0){ dup2(pipefd[count - 2][0],0); /*middle commands*/ dup2(pipefd[count - 1][1],1); } else if(last == 1){ dup2(pipefd[count - 1][0],0); /*last command*/ } for(i = 0; i < count;i++){/*close pipes*/ for(i2 = 0; i2 < 2;i2++){ close(pipefd[i][i2]); }} if(type == 0){ execlp("ls","ls","-al",NULL); } else if(type == 1){ execlp("grep","grep",".bak",NULL); } else if(type==2){ execl("/usr/bin/wc","wc",NULL); } else if(type ==3){ execl("/usr/bin/wc","wc","-l",NULL); } perror("exec"); exit(EXIT_FAILURE); } else if (child_pid < 0) { perror("fork"); exit(EXIT_FAILURE); } } I checked the file descriptors and it is opening the right ones, not sure what the problem could be..

  • Struts2 + jQuery Autocompletion (Solved, with DOJO :) )

    - by Luigi 1982
    I used the jQuery autocompletion for my Struts2 application. Pratically, my action made a list of strings that jQuery use. This is the script: $().ready(function() { $("#tag").autocomplete("/myAction/Action", { multiple : true, autoFill : true, minChars:1 }); }); During typing appear the box with the suggestions. The problem is that the box render another value, exactly render the code of my JSP ( links to CSS for the autocomplete plug-in). How can I solve this? This is my JSP: <html> <head> <script src="<%=request.getContextPath()%>/scripts/jquery-latest.js"></script> <link rel="stylesheet" href="<%=request.getContextPath()%>/scripts/main.css" type="text/css" /> <link rel="stylesheet" href="<%=request.getContextPath()%>/scripts/jquery.autocomplete.css" type="text/css" /> <script type="text/javascript" src="<%=request.getContextPath()%>scripts/jquery.bgiframe.min.js"></script> <script type="text/javascript" src="/<%=request.getContextPath()%>/query.dimensions.js"></script> <script type="text/javascript" src="<%=request.getContextPath()%>/scripts/jquery.autocomplete.js"></script> <script type="text/javascript"> $().ready(function() { $("#tag").autocomplete("/myAction/Action", { multiple : true, autoFill : true, minChars:1 }); }); </script> </head> <body> <s:form action="Action" theme="simple"> <s:iterator value="elencoMateriali" var="asd"> <s:property value="#asd" escape="false"/> </s:iterator> <s:textfield id="tag" name="tagField" label="tag" /> </s:form> </body>

  • recursive delete trigger and ON DELETE CASCADE contraints are not deleting everything

    - by bitbonk
    I have a very simple datamodel that represents a tree structure: The RootEntity is the root of such a tree, it can contain children of type ContainerEntity and of type AtomEntity. The type ContainerEntity again can contain children of type ContainerEntity and of type AtomEntity but can not contain children of type RootEntity. Children are referenced in a well known order. The DB model for this is below. My problem now is that when I delete a RootEntity I want all children to be deleted recursively. I have create foreign key with CASCADE DELETE and two delete triggers for this. But it is not deleting everything, it always leaves some items in the ContainerEntity, AtomEntity, ContainerEntity_Children and AtomEntity_Children tables. Seemling beginning with the recursionlevel of 3. CREATE TABLE RootEntity ( Id UNIQUEIDENTIFIER NOT NULL, Name VARCHAR(500) NOT NULL, CONSTRAINT PK_RootEntity PRIMARY KEY NONCLUSTERED (Id), ); CREATE TABLE ContainerEntity ( Id UNIQUEIDENTIFIER NOT NULL, Name VARCHAR(500) NOT NULL, CONSTRAINT PK_ContainerEntity PRIMARY KEY NONCLUSTERED (Id), ); CREATE TABLE AtomEntity ( Id UNIQUEIDENTIFIER NOT NULL, Name VARCHAR(500) NOT NULL, CONSTRAINT PK_AtomEntity PRIMARY KEY NONCLUSTERED (Id), ); CREATE TABLE RootEntity_Children ( ParentId UNIQUEIDENTIFIER NOT NULL, OrderIndex INT NOT NULL, ChildContainerEntityId UNIQUEIDENTIFIER NULL, ChildAtomEntityId UNIQUEIDENTIFIER NULL, ChildIsContainerEntity BIT NOT NULL, CONSTRAINT PK_RootEntity_Children PRIMARY KEY NONCLUSTERED (ParentId, OrderIndex), -- foreign key to parent RootEntity CONSTRAINT FK_RootEntiry_Children__RootEntity FOREIGN KEY (ParentId) REFERENCES RootEntity (Id) ON DELETE CASCADE, -- foreign key to referenced (child) ContainerEntity CONSTRAINT FK_RootEntiry_Children__ContainerEntity FOREIGN KEY (ChildContainerEntityId) REFERENCES ContainerEntity (Id) ON DELETE CASCADE, -- foreign key to referenced (child) AtomEntity CONSTRAINT FK_RootEntiry_Children__AtomEntity FOREIGN KEY (ChildAtomEntityId) REFERENCES AtomEntity (Id) ON DELETE CASCADE, ); CREATE TABLE ContainerEntity_Children ( ParentId UNIQUEIDENTIFIER NOT NULL, OrderIndex INT NOT NULL, ChildContainerEntityId UNIQUEIDENTIFIER NULL, ChildAtomEntityId UNIQUEIDENTIFIER NULL, ChildIsContainerEntity BIT NOT NULL, CONSTRAINT PK_ContainerEntity_Children PRIMARY KEY NONCLUSTERED (ParentId, OrderIndex), -- foreign key to parent ContainerEntity CONSTRAINT FK_ContainerEntity_Children__RootEntity FOREIGN KEY (ParentId) REFERENCES ContainerEntity (Id) ON DELETE CASCADE, -- foreign key to referenced (child) ContainerEntity CONSTRAINT FK_ContainerEntity_Children__ContainerEntity FOREIGN KEY (ChildContainerEntityId) REFERENCES ContainerEntity (Id) ON DELETE CASCADE, -- foreign key to referenced (child) AtomEntity CONSTRAINT FK_ContainerEntity_Children__AtomEntity FOREIGN KEY (ChildAtomEntityId) REFERENCES AtomEntity (Id) ON DELETE CASCADE, ); CREATE TRIGGER Delete_RootEntity_Children ON RootEntity_Children FOR DELETE AS DELETE FROM ContainerEntity WHERE Id IN (SELECT ChildContainerEntityId FROM deleted) DELETE FROM AtomEntity WHERE Id IN (SELECT ChildAtomEntityId FROM deleted) GO CREATE TRIGGER Delete_ContainerEntiy_Children ON ContainerEntity_Children FOR DELETE AS DELETE FROM ContainerEntity WHERE Id IN (SELECT ChildContainerEntityId FROM deleted) DELETE FROM AtomEntity WHERE Id IN (SELECT ChildAtomEntityId FROM deleted) GO
