  • Object reference not set to an instance of an object.....?

    - by jamal
    Hi guys I always got this error from my site and it keeps bugging me.I've been trying to figure out the cause of this error but I can't really figure it out. Here's the stacktrace: at BasePage.Page_PreInit(Object sender, EventArgs e) at System.EventHandler.Invoke(Object sender, EventArgs e) at System.Web.UI.Page.OnPreInit(EventArgs e) at System.Web.UI.Page.PerformPreInit() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) And on my basepage I only got this code: Imports Microsoft.VisualBasic Public Class BasePage Inherits System.Web.UI.Page Private Sub Page_PreInit(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreInit Page.Theme = "Something" If (Request.UserAgent.IndexOf("AppleWebKit") 0) Then Request.Browser.Adapters.Clear() End If End Sub Private Sub Page_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreRender If Me.Title = "Untitled Page" Then Throw New Exception("Page title cannot be ""Untitled Page"".") End If End Sub End Class According to the stacktrace this always happens on my basepage preinit event.What do you think is the problem here guys?

  • Is it possible to set a parameterized build or pass an environment variable via a hudson build trigger?

    - by Tim
    I'd like to use hudson to trigger a "promotion" of a build. The build would be a simple script that just copies a release candidate installer file from one location to another. (development dir to release/stable dir) Our build server is not on the public internet, but I want to be able to send an email or a text message or an IM with the build number to hudson, which will parse the build number and then do the copy/move. In looking at the jabber/IM plugin it does not look like this is possible (the parameter part) Has anyone solved this in some way? Should I use some other mechanism? I would prefer not to have to do the manual steps each time (SCP/FTP, etc) - I just want any QA team member to be able to trigger the build server to do the promotion.

  • Pass information to php file from javascript while restricting user from doing it their self?

    - by Sean Madigan
    I am making a game where the battle system uses javascript to battle. At the end of the battle you either win or lose. If the user wins, I need to update the mysql database with the XP they earned. The best way I can think of doing this is to have the javascript run an ajax function when the user wins that POSTs something like addxp.php?amount=235, but if I do that then the user can easilly look at the source and see that they can just enter in that page themself to update their xp without battling. But this is the only way I know how to do it? Help please :-/

  • How do I pass a multi-dimensional array as a GET parameter in PHP?

    - by Onema
    I have the following code. $connect = new Connection (); $response = $connect->putFile($fileName, $destination); header("Location: /test.php?response=" . $response); When I invoke header with the response, the file will stop execution, but I will have no error in the console... I am thinking maybe this array needs to be encoded for the url? if that is the case how? Thank you

  • What is the ISO C++ way to directly define a conversion function to reference to array?

    - by ben
    According to the standard, a conversion function has a function-id operator conversion-type-id, which would look like, say, operator char(&)[4] I believe. But I cannot figure out where to put the function parameter list. gcc does not accept either of operator char(&())[4] or operator char(&)[4]() or anything I can think of. Now, gcc seems to accept (&operator char ())[4] but clang does not, and I am inclined to not either, since it does not seem to fit the grammar as I understand it. I do not want to use a typedef because I want to avoid polluting the namespace with it.

  • How does Symfony pass members set in an action to a template?

    - by Martin Chatterton
    How does a member set inside an action... $this->foo = 'bar'; ...become a variable accessible from a template... echo $foo; // bar I would like to know how it is achieved at a framework level. There is a lot of documentation on how to use Symfony, but I've not managed to find much about how it all fits together behind the scenes (class structure/inheritance etc). Thanks in advance for your help!

  • How do I pass Url Parameters on a POST?

    - by Robert Harvey
    I have a controller method with the following signature: [AcceptVerbs(HttpVerbs.Post)] public ActionResult UpdateValues(int id, MyViewModel[] array) { } The id is normally picked up as part of the Url on other GET controller methods (I have a working route that does this) I am successfully passing the array1 from the form in my view to the controller method, but how do I also put the id onto my Url so that when the user clicks the Submit button, the controller method will pick up the ID?

  • Can I pass a string variable into an <a href> tag for a website link?

    - by Joseph
    I am somewhat new to web developing, so I am trying to learn along the way. I have a div that is 500 x 500. Inside of that div I have two divs that are each 250x500. So my outer div is filled up with the two inner divs. I have it setup so that when I click on the first div (the left one) a java script is called, and a prompt pop up box asks for a website URL which is then stored inside of a string variable. How can I make it so that the second div (the right one) takes the string variable from the alert box from the left div and puts it into an a href tag so that I can link to the website from the right div? Can a a href tag accept a value from a variable for its link? Maybe I am going about this all wrong, is there a better way I should be approaching this? Any help is appreciated!!

  • Is foreign key reference from two different primary key from two different tables valid?

    - by arundex
    I have a foreign key that has to refer primary keys of two different tables. Table 1: animal animal_ id (primary key) Table 2: bird bird_ id (primary key) Table 3: Pet_info pet_id, type ENUM ('bird', 'animal') foreign key (pet_ id) references animal(animal_id), bird(bird_id) So, I need to check for pet_id either from animal or bird table depending on the need. Is this valid? Or should I go for some restructuring . . . NOTE: I referred this . . but I'm not sure whether I have to change my existing design

  • How to pass a class method as an argument for another function in C++ and openGL?

    - by tsubasa
    I know this thing works: void myDisplay() { ... } int main() { ... glutDisplayFunc(myDisplay) ... } so I tried to include myDisplay() function to a class that I made. Because I want to overload it in the future with a different class. However, the compiler complains that argument of type 'void (ClassBlah::)()' does not match 'void(*)()' . Here is the what I try to make: class ClassBlah { .... void myDisplay() .... } ...... int main() { ... ClassBlah blah glutDisplayFunc(blah.myDisplay) ... } Does anybody knows how to fix this problem? Many thanks.

  • When I try to pass large amounts of information using jquery $.ajax(post) method. it throws potenti

    - by dotnetrocks
    I am trying to create a preview window for my texteditor in my blog page. I need to send the content to the server to clean up the text entered before I can preview it on the preview window. I was trying to use $.ajax({ type: method, url: url, data: values, success: LoadPageCallback(targetID), error: function(msg) { $('#' + targetID).attr('innerHTML', 'An error has occurred. Please try again.'); } }); Whenever I tried to click on the preview button it returns an XMLHTTPRequest error. The error description - Description: Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted. This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack. You can disable request validation by setting validateRequest=false in the Page directive or in the configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case. The ValidateRequest for the page is set to false. Is there a way I can set validaterequest to false for the ajax call.Please advise Thank you for reading my post.

  • How do I pass dependency to object with Castle Windsor and MS Test?

    - by Nick
    I am trying to use Castle Windsor with MS Test. The test class only seems to use the default constructor. How do I configure Castle to resolve the service in the constructor? Here is the Test Class' constructors: private readonly IWebBrowser _browser; public DepressionSummaryTests() { } public DepressionSummaryTests(IWebBrowser browser) { _browser = browser; } My component in the app config looks like so: <castle> <components> <component id="browser" service="ConversationSummary.IWebBrowser, ConversationSummary" type="ConversationSummary.Browser" /> </components> </castle> Here is my application container: public class ApplicationContainer : WindsorContainer { private static IWindsorContainer container; static ApplicationContainer() { container = new WindsorContainer(new XmlInterpreter(new ConfigResource("castle"))); } private static IWindsorContainer Container { get { return container; } } public static IWebBrowser Browser { get { return (IWebBrowser) Container.Resolve("browser"); } } } MS test requires the default constructor. What am I missing? Thanks!

  • Can I get a reference to an object created in a jQuery plugin?

    - by gargantaun
    Perhaps my brain is fried, but I'm writing a plugin that created an tweaks an element, but also creates an object that i'd like access to. So the plugin looks like this (function ($) { $.fn.myPlugin = function () { return this.each(function () { // do some stuff to the element... this.objectInstance = new usefulObject(); }); }; })(jQuery); function usefulObject(){ // useful object properties and methods.... this.doSomething = function(){ alert("Don't google Google. You'll break the internet."); } } so when I call the plugin, I also want to be able to get access to that usefulObject that I created. I thought something like this might work.... tweakedElement = $("#someDiv").myPlugin(); tweakedElement.objectInstance.doSomething(); ... but that's not working. How can I achieve this? Can I achieve this? Answers on a postcard, or down below, whichever suits you.

  • Pass object from JSON into MVC Controller - its always null ?

    - by SteveCl
    Hi I have seen a few questions on here related to the a similar issue, I have read them, followed them, but still i have the same problem. I am basically creating an object in javascript and trying to call a method on the controller that will return a string of html. Not JSON. I've been playing around with dataType and contentType but still no joy. So apologies if the code snippets are a bit messy. Build the object in JS. function GetCardModel() { var card = {}; card.CardTitle = $("#CardTitle").val(); card.TopicTitle = $("#TopicTitle").val(); card.TopicBody = $("#TopicBody").data("tEditor").value(); card.CardClose = $("#CardClose").val(); card.CardFromName = $("#CardFromName").val(); return card; } Take a look at the object - all looks good and as it should in JSON. var model = GetCardModel(); alert(JSON.stringify(GetCardModel())); Make the call... $.ajax({ type: "POST", url: "/Postcard/Create/Preview/", dataType: "json", //contentType: "application/json", date: GetCardModel(), processData: true, success: function (data) { alert("im back"); alert(data); }, error: function (xhr, ajaxOptions, error) { alert(xhr.status); alert("Error: " + xhr.responseText); //alert(error); } }); Always when I step into the controller, the object is ALWAYS there, but with null values for all the properties.

  • Where can I find "reference barcodes" to verify barcode library output?

    - by mjustin
    This question is not about 'best' barcode library recommendation, we use various products on different platforms, and need a simple way to verify if a given barcode is correct (according to its specification). There are some free online bar code generators in the Internet, and I found many differences between their output and our library output regarding graphics and text field below the code. Now I am not sure which one is wrong, and before filing bug report I want to make sure how the correct barcode should look like. We mainly need Code128 and UCC/EAN-128 with A/B/C subcodes. Which resource would you suggest?

  • How to pass a value between Silverlight pages for WP7?

    - by Sebastian Gray
    I've got a MainPage.xaml page a Detail.xaml page. I've passed variables to the Detail.xaml from MainPage.xaml by using a static variable and referencing it in Detail.xaml (the detail page is acting like a dialog). However once I've updated the content of another object, I want to call a method in MainPage.xaml to refresh the content of that page using the updated object from the Detail.xaml page. I assume I am not using the correct paradigm for this and should probably be using MVVM or something but I'm not familiar with the implementation and was hoping there was a simple way to do this?

  • Cannot pass a input from text box to a query string and then keep the string in this box.

    - by Nikita Barsukov
    I have a simple ASP.net page: <form id="form1" runat="server"> <p><asp:TextBox id="input_box" runat="server"></asp:TextBox> <asp:Button Text="OK" runat="server" OnClick="run" /></p> </form> I want to send input from input_box to a query string, and then keep this input in the input_box when the page reloads. That's the code behind page: protected void Page_Load(object sender, EventArgs e) { input_box.Text = Request.QueryString["input"]; } protected void run(object sender, EventArgs e) { string url = string.Format("?input={0}", input_box.Text); Response.Redirect(Request.Url.AbsolutePath + url); } Problem is that when query string is not empty, string from input_box cannot be passed to query string. How to correct it?
