  • Adding nodes to drupal from remote site using ajax and post

    - by andersandersson666
    I'm trying to add nodes to my drupal site, from a campaignsite using AJAX request. I have set up a menu_callback item in my hook_menu, that checks if any $_POSTs are coming in, and it works if i make a form that has the action='http://mysite.com/menucallback/url', but i get nothing in response if i make the same request with ajax. I have access arguments set to 'access content'. If anyone knows what might be the problem, that would be very helpful. Thank you. /Anders

  • Selecting one row when working with typed datasets.

    - by Wodzu
    I have a typed dataset in my project. I would like to populate a datatable with only one row instead of all rows. The selected row must be based on the primary key column. I know I could modify the designer code to achive this functionality however if I change the code in the designer I risk that this code will be deleted when I update my datased via designer in the future. So I wanted to alter the SelectCommand not in the designer but just before firing up MyTypedTableAdapter.Fill method. The strange thing is that the designer does not create a SelectCommand! It creates all other commands but not this one. If it would create SelectCommand I could alter it in this way: this.operatorzyTableAdapter.Adapter.SelectCommand.CommandText += " WHERE MyColumn = 1"; It is far from perfection but atleast I would not have to modify the designer's work. unfortunately as I said earlier the SelectCommand is not created. Instead designer creates something like this: [global::System.Diagnostics.DebuggerNonUserCodeAttribute()] private void InitCommandCollection() { this._commandCollection = new global::System.Data.SqlClient.SqlCommand[1]; this._commandCollection[0] = new global::System.Data.SqlClient.SqlCommand(); this._commandCollection[0].Connection = this.Connection; this._commandCollection[0].CommandText = "SELECT Ope_OpeID, Ope_Kod, Ope_Haslo, Ope_Imie, Ope_Nazwisko FROM dbo.Operatorzy"; this._commandCollection[0].CommandType = global::System.Data.CommandType.Text; } It doesn't make sense in my opinion. Why to create UpdateCommand, InsertCommand and DeleteCommand but do not create SelectCommand? I could bear with this but this._commandCollection is private so I cannot acces it outside of the class code. I don't know how to get into this collection without changing the designer's code. The idea which I have is to expose the collection via partial class definition. However I want to introduce many typed datasets and I really don't want to create partial class definition for each of them. Please note that I am using .NET 3.5. I've found this article about accessing private properties but it concerns .NET 4.0 Thanks for your time.

  • Setting property of objects in datacontext

    - by ryudice
    Hi, all my entities have a common property which specifies the company they belong to, I would like to set this property in a method in my datacontext but I do not want to use the partial methods for each of the entity types that the datacontext provides, is there a method that receives any entity that is inserted throught the datacontext so that I can hook to it or override it and set the property using reflection? thanks.

  • how to: handle exceptions, best practices

    - by b0x0rz
    need to implement a global error handling, so maybe you can help out with the following example... i have this code: public bool IsUserAuthorizedToSignIn(string userEMailAddress, string userPassword) { // get MD5 hash for use in the LINQ query string passwordSaltedHash = this.PasswordSaltedHash(userEMailAddress, userPassword); // check for email / password / validity using (UserManagementDataContext context = new UserManagementDataContext()) { var users = from u in context.Users where u.UserEMailAdresses.Any(e => e.EMailAddress == userEMailAddress) && u.UserPasswords.Any(p => p.PasswordSaltedHash == passwordSaltedHash) && u.IsActive == true select u; // true if user found return (users.Count() == 1) ? true : false; } } and the md5 as well: private string PasswordSaltedHash(string userEMailAddress, string userPassword) { MD5 hasher = MD5.Create(); byte[] data = hasher.ComputeHash(Encoding.Default.GetBytes(userPassword + userEMailAddress)); StringBuilder stringBuilder = new StringBuilder(); for (int i = 0; i < data.Length; i++) { stringBuilder.Append(data[i].ToString("x2")); } Trace.WriteLine(String.Empty); Trace.WriteLine("hash: " + stringBuilder.ToString()); return stringBuilder.ToString(); } so, how would i go about handling exceptions from these functions? they first one is called from the Default.aspx page. the second one is only called from other functions from the class library. what is the best practice? surround code INSIDE each function with try-catch surround the FUNCTION CALL with try-catch something else?? what to do if exceptions happen? in this example: this is a user sign in, so somehow even if everything fails, the user should get some meaningful info - along the lines: sign in ok (just redirect), sign in not ok (wrong user name / password), sign in not possible due to internal problems, sorry (exception happened). for the first function i am worried if there is a problem with database access. not sure if there is anything that needs to be handled in the second one. thnx for the info. how would you do it? need specific info on this (easier for me to understand), but also general info on how to handle other tasks/functions. i looked around the internet but everyone has different things to say, so unsure what to do... will go with either most votes here, or most logicaly explained answer :) thank you.

  • How can I await the first completed async task of a list in .Net?

    - by Eyal
    My input is a long list of files located on an Amazon S3 server. I'd like to download the metadata of the files, compute the hashes of the local files, and compare the metadata hash with the local files' hash. Currently, I use a loop to start all the metadata downloads asynchronously, then as each completes, compute MD5 on the local file if needed and compare. Here's the code (just the relevant lines): Dim s3client As New AmazonS3Client(KeyId.Text, keySecret.Text) Dim responseTasks As New List(Of System.Tuple(Of ListViewItem, Task(Of GetObjectMetadataResponse))) For Each lvi As ListViewItem In lvStatus.Items Dim gomr As New Amazon.S3.Model.GetObjectMetadataRequest gomr.BucketName = S3FileDialog.GetBucketName(lvi.SubItems(2).Text) gomr.Key = S3FileDialog.GetPrefix(lvi.SubItems(2).Text) responseTasks.Add(New System.Tuple(Of ListViewItem, Task(Of GetObjectMetadataResponse))(lvi, s3client.GetObjectMetadataAsync(gomr))) Next For Each t As System.Tuple(Of ListViewItem, Task(Of GetObjectMetadataResponse)) In responseTasks Dim response As GetObjectMetadataResponse = Await t.Item2 If response.ETag.Trim(""""c) = MD5CalcFile(lvi.SubItems(1).Text) Then lvi.SubItems(3).Text = "Match" UpdateLvi(lvi) End If Next I've got two problems: I'm awaiting the reponses in the order that I made them. I'd rather process them in the order that they complete so that I get them faster. The MD5 calculation is long and synchronous. I tried making it async but the process locked up. I think that the MD5 task was added to the end of .Net's task list and it didn't get to run until all the downloads completed. Ideally, I process the response as they arrive, not in order, and the MD5 is asynchronous but gets a chance to run. Edit: Incorporating WhenAll, it looks like this now: Dim s3client As New Amazon.S3.AmazonS3Client(KeyId.Text, keySecret.Text) Dim responseTasks As New Dictionary(Of Task(Of GetObjectMetadataResponse), ListViewItem) For Each lvi As ListViewItem In lvStatus.Items Dim gomr As New Amazon.S3.Model.GetObjectMetadataRequest gomr.BucketName = S3FileDialog.GetBucketName(lvi.SubItems(2).Text) gomr.Key = S3FileDialog.GetPrefix(lvi.SubItems(2).Text) responseTasks.Add(s3client.GetObjectMetadataAsync(gomr), lvi) Next Dim startTime As DateTimeOffset = DateTimeOffset.Now Do While responseTasks.Count > 0 Dim currentTask As Task(Of GetObjectMetadataResponse) = Await Task.WhenAny(responseTasks.Keys) Dim response As GetObjectMetadataResponse = Await currentTask If response.ETag.Trim(""""c) = MD5CalcFile(lvi.SubItems(1).Text) Then lvi.SubItems(3).Text = "Match" UpdateLvi(lvi) End If Loop MsgBox((DateTimeOffset.Now - startTime).ToString) The UI locks up momentarily whenever MDSCalcFile is done. The whole loop takes about 45s and the first file's MD5 result happens within 1s of starting. If I change the line to: If response.ETag.Trim(""""c) = Await Task.Run(Function () MD5CalcFile(lvi.SubItems(1).Text)) Then The UI doesn't lock up when MD5CalcFile is done. The whole loop takes about 75s, up from 45s, and the first file's MD5 result happens after 40s of waiting.

  • Using RhinoMocks, how do you mock or stub a concrete class without an empty constructor?

    - by Mark Rogers
    Mocking a concrete class with Rhino Mocks seems to work pretty easy when you have an empty constructor on a class: public class MyClass{ public MyClass() {} } But if I add a constructor that takes parameters and remove the one that doesn't take parameters: public class MyClass{ public MyClass(MyOtherClass instance) {} } I tend to get an exception: System.MissingMethodException : Can't find a constructor with matching arguments I've tried putting in nulls in my call to Mock or Stub, but it doesn't work. Can I create mocks or stubs of concrete classes with Rhino Mocks, or must I always supply (implicitly or explicitly) a parameter-less constructor?

    I am using both JQuery UI Dialog and JQuery UI autocomplete both have the same erroneous behavior when they popup, the position is always 0,0! I have tried some different position arguments when popping up the dialog but non seems to help. Any clues? Is this a bug in the position calculation in JQuery? Or is this some css bug? Versions are 1.4.2 and 1.8.0

  • How to access a named element of a derived user control in silverlight ?

    - by Mrt
    Hello, I have a custom base user control in silverlight. <UserControl x:Class="Problemo.MyBaseControl" 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" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="400"> <Grid x:Name="LayoutRoot" Background="White"> <Border Name="HeaderControl" Background="Red" /> </Grid> </UserControl> With the following code behind public partial class MyBaseControl : UserControl { public UIElement Header { get; set; } public MyBaseControl() { InitializeComponent(); Loaded += MyBaseControl_Loaded; } void MyBaseControl_Loaded(object sender, RoutedEventArgs e) { HeaderControl.Child = Header; } } I have a derived control. <me:MyBaseControl x:Class="Problemo.MyControl" 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" mc:Ignorable="d" xmlns:me="clr-namespace:Problemo" d:DesignHeight="300" d:DesignWidth="400"> <me:MyBaseControl.Header> <TextBlock Name="header" Text="{Binding Text}" /> </me:MyBaseControl.Header> </me:MyBaseControl> With the following code behind. public partial class MyControl : MyBaseControl { public string Text { get; set; } public MyControl(string text) { InitializeComponent(); Text = text; } } I'm trying to set the text value of the header textblock in the derived control. It would be nice to be able to set both ways, i.e. with databinding or in the derived control code behind, but neither work. With the data binding, it doesn't work. If I try in the code behind I get a null reference to 'header'. This is silverlight 4 (not sure if that makes a difference) Any suggestions on how to do with with both databinding and in code ? Cheers

  • getting the "this" that a function's caller was called with in JavaScript

    - by David Morrissey
    Is it possible to get the this that a function's caller was called with in JavaScript without passing this to the arguments in a way which supports IE as well as Firefox/Chrome et al? For example: var ob = { callme: function() { doSomething() } } function doSomething() { alert(doSomething.caller.this === ob) // how can I make this work? } ob.callme() I'm starting to suspect it's not, but I thought I may as well ask as it'd make my code much shorter and easier to read. Thanks for any information!

  • Can a single argument constructor with a default value be subject to implicit type conversion

    - by Richard
    I understand the use of the explicit keyword to avoid the implicit type conversions that can occur with a single argument constructor, or with a constructor that has multiple arguments of which only the first does not have a default value. However, I was wondering, does a single argument constructor with a default value behave the same as one without a default value when it comes to implicit conversions?

  • Matching strings

    - by Joy
    Write the function subStringMatchExact. This function takes two arguments: a target string, and a key string. It should return a tuple of the starting points of matches of the key string in the target string, when indexing starts at 0. Complete the definition for def subStringMatchExact(target,key): For example, subStringMatchExact("atgacatgcacaagtatgcat","atgc") would return the tuple (5, 15).

  • MVC3/Razor Client Validation Not firing

    - by Jason Gerstorff
    I am trying to get client validation working in MVC3 using data annotations. I have looked at similar posts including this MVC3 Client side validation not working for the answer. I'm using an EF data model. I created a partial class like this for my validations. [MetadataType(typeof(Post_Validation))] public partial class Post { } public class Post_Validation { [Required(ErrorMessage = "Title is required")] [StringLength(5, ErrorMessage = "Title may not be longer than 5 characters")] public string Title { get; set; } [Required(ErrorMessage = "Text is required")] [DataType(DataType.MultilineText)] public string Text { get; set; } [Required(ErrorMessage = "Publish Date is required")] [DataType(DataType.DateTime)] public DateTime PublishDate { get; set; } } My cshtml page includes the following. <h2>Create</h2> <script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script> @using (Html.BeginForm()) { @Html.ValidationSummary(true) Post <div class="editor-label"> @Html.LabelFor(model => model.Title) </div> <div class="editor-field"> @Html.EditorFor(model => model.Title) @Html.ValidationMessageFor(model => model.Title) </div> <div class="editor-label"> @Html.LabelFor(model => model.Text) </div> <div class="editor-field"> @Html.EditorFor(model => model.Text) @Html.ValidationMessageFor(model => model.Text) Web Config: <appSettings> <add key="ClientValidationEnabled" value="true" /> <add key="UnobtrusiveJavaScriptEnabled" value="true" /> Layout: <head> <title>@ViewBag.Title</title> <link href="@Url.Content("~/Content/Site.css")" rel="stylesheet" type="text/css" /> <script src="@Url.Content("~/Scripts/jquery-1.4.4.min.js")" type="text/javascript"></script> So, the Multiline Text annotation works and creates a text area. But none of the validations work client side. I don't know what i might be missing. Any ideas?? i can post more information if needed. Thanks!

  • Running shell scripts with sudo through my web app

    I have some functionality that interfaces with the server's OS in my web application. I've written a bash script and am able to run it from within my app. However, some functionality of the script requires superuser privileges. What is the most sane way to run this script securely? It is being passed arguments from a web form, but should only be able to be called by authenticated users that I trust not to haxxor it.

  • Keyboard input with timeout in Python

    How would you prompt the user for some input but timing out after N seconds? Google is pointing to a mail thread about it at http://mail.python.org/pipermail/python-list/2006-January/533215.html but it seems not to work. The statement in which the timeout happens, no matter whether it is a sys.input.readline or timer.sleep(), I always get: <type 'exceptions.TypeError'>: [raw_]input expected at most 1 arguments, got 2 which somehow the except fails to catch.

  • Good policy to force all developers in a company to use the same IDE?

    - by Henrik
    In my organization they are thinking about rolling out Eclipse company wide but I prefer using another editor (UltraEdit). I do not have any good arguments against this except subjective opinions that a developer should get to use whatever he/she wants as long as he's productive enough. This to make the developer a happy employee :-) Do you guys think its a good policy to force all developers in the same company to use the same IDE? Would there be any technical (dis)advantages of this decision?

  • Is there simple way how to join two RouteValueDictionary values to pass parameters to Html.ActionLin

    - by atagaew
    Hi. Look on my code that i created in a partial View: <% foreach (Customer customerInfo in Model.DataRows) {%> <tr> <td> <%=Html.ActionLink( customerInfo.FullName , ((string)ViewData["ActionNameForSelectedCustomer"]) , JoinParameters(customerInfo.id, (RouteValueDictionary) ViewData["AdditionalSelectionParameters"]) , null)%> </td> <td> <%=customerInfo.LegalGuardianName %> </td> <td> <%=customerInfo.HomePhone %> </td> <td> <%=customerInfo.CellPhone %> </td> </tr> <%}%> Here I'm building simple table that showing customer's details. As you may see, in each row, I'm trying to build a link that will redirect to another action. That action requires customerId and some additional parameters. Additional parameters are different for each page where this partial View is using. So, i decided to make Action methods to pass that additional parameters in the ViewData as RouteValueDictionary instance. Now, on the view i have a problem, i need to pass customerId and that RouteValueDictionary together into Html.ActionLink method. That makes me to figure out some way of how to combine all that params into one object (either object or new RouteValueDictionary instance) Because of the way the MVC does, i can't create create a method in the codebehind class (there is no codebihind in MVC) that will join that parameters. So, i used ugly way - inserted inline code: ...script runat="server"... private RouteValueDictionary JoinParameters(int customerId, RouteValueDictionary defaultValues) { RouteValueDictionary routeValueDictionary = new RouteValueDictionary(defaultValues); routeValueDictionary.Add("customerId", customerId); return routeValueDictionary; } ...script... This way is very ugly for me, because i hate to use inline code in the View part. My question is - is there any better way of how i can mix parameters passed from the action (in ViewData, TempData, other...) and the parameter from the view when building action links. May be i can build this link in other way ? Thanks!

  • High-level languages for out-of-the-box GUI desktop application programming

    - by Omeoe
    After I discontinued programming in C++ while entering into web authoring I was spoilt by PHP's high level constructs like hash tables or its dynamic, weak typing. I remembered the angst of C/C++ pointers and the maze of low-level Win32 API handles and message loops and that prevented me from utilizing environments like Code::Blocks for desktop applications. I am also not very fond of bulky, statically-typed C#/.NET environment. Any other ideas?
