  • how to check if the enddate is after the startdate in a zend form

    - by murze
    I have a zend form with a start- and an endate. $form = new Zend_Form(); $form->setName($this->formName) ->setMethod('post'); $feStartdate = new Zend_Form_Element_Text('startdate'); $feEnddate = new Zend_Form_Element_Text('enddate'); $form->addElement($feStartDate) ->addElement($feEndDate) ->addElement('submit', 'submit', array('label' => 'Save')); I assume I must write a custom validator for to check this. How would this custom validator look like and how can I call it? I assume something like $feEnddate->addValidator('dateComesAfter', $feStartDate)

  • How to keep views free of authorization logic in mvc?

    - by David Lay
    I have a view to display a list of items. The user can edit, delete or create new items, but according to their authorizations they may or may not be allowed to do some of this actions. I have the requirement to display only the actions which the current user is allowed to do, but I don't want to clutter the views with authorization if-else's Despise of being a very common requirement, I can't find a real satisfactory way of doing it. My best approach so far is to provide an overload to the Html.ActionLink extension method that takes the permission to ask for, but there are going to be more complex scenarios, like hiding entire blocks of html or switching a textbox for a label+hidden. Is there a better way to do this?

  • ZedGraph labels

    - by eKek0
    In ZedGraph how to show text labels for each point and in the XAxis all together? EDIT: If I do myPane.XAxis.Type = AxisType.Text; myPane.XAxis.Scale.TextLabels = array_of_string; I get labels on the XAxis like this And if I do for (int i = 0; i < myCurve.Points.Count; i++) { PointPair pt = myCurve.Points[i]; // Create a text label from the Y data value TextObj text = new TextObj(pt.Y.ToString("f0"), pt.X, pt.Y + 0.1, CoordType.AxisXYScale, AlignH.Left, AlignV.Center); text.ZOrder = ZOrder.A_InFront; text.FontSpec.Angle = 0; myPane.GraphObjList.Add(text); } I get labels on the curve, like this But if I do both at the same time, labels on the curve disappear. Is there a way to combine both kind of labels?

  • Scaled ellipse over button, button not clickable

    - by user336720
    Hi, I'm scaling an ellipse in an animation with the following code: ScaleTransform myScTransform = new ScaleTransform(); TransformGroup myTransGroup = new TransformGroup(); myTransGroup.Children.Add(myScTransform); newPHRadio.RenderTransform = myTransGroup; newPHRadio.RenderTransformOrigin = new Point(0.5, 0.5); Storyboard story = new Storyboard(); DoubleAnimation xAnimation = new DoubleAnimation(1, ph.Bereik, new Duration(TimeSpan.FromSeconds(2))); DoubleAnimation yAnimation = new DoubleAnimation(1, ph.Bereik, new Duration(TimeSpan.FromSeconds(2))); DoubleAnimation doorzichtig = new DoubleAnimation(1, 0, new Duration(TimeSpan.FromSeconds(2))); Storyboard.SetTarget(xAnimation, newPHRadio); Storyboard.SetTarget(yAnimation, newPHRadio); Storyboard.SetTarget(doorzichtig, newPHRadio); DependencyProperty[] propertyChainX = new DependencyProperty[] { Ellipse.RenderTransformProperty, TransformGroup.ChildrenProperty, ScaleTransform.ScaleXProperty }; DependencyProperty[] propertyChainY = new DependencyProperty[] { Ellipse.RenderTransformProperty, TransformGroup.ChildrenProperty, ScaleTransform.ScaleYProperty }; string thePath = "(0).(1)[0].(2)"; Storyboard.SetTargetProperty(xAnimation, new PropertyPath(thePath, propertyChainX)); Storyboard.SetTargetProperty(yAnimation, new PropertyPath(thePath, propertyChainY)); Storyboard.SetTargetProperty(doorzichtig, new PropertyPath(Ellipse.OpacityProperty)); story.Children.Add(xAnimation); story.Children.Add(yAnimation); story.Children.Add(doorzichtig); story.Duration = new Duration(TimeSpan.FromSeconds(60 / ph.Frequentie)); story.RepeatBehavior = RepeatBehavior.Forever; story.Begin(); The ellipse is constructed with the following code: Ellipse newPHRadio = new Ellipse(); newPHRadio.Width = 1; newPHRadio.Height = 1; newPHRadio.SetValue(Canvas.LeftProperty, ph.xPositie + 7); newPHRadio.SetValue(Canvas.TopProperty, ph.yPositie + 7); newPHRadio.SetValue(Canvas.ZIndexProperty, 3); newPHRadio.Stroke = new SolidColorBrush(Colors.Black); newPHRadio.StrokeThickness = 0.03; Now the ellipse is scaled over an button which has a z-index of 1. With a static ellipse and no fill, the button is clickable. Now there is no fill as well but the button is not clickable. Can someone tell me how to fix this?

  • Graphical net and text

    - by chesheerkys
    Hello! My task is to make a control, that behaves itself like RichTextBox, but contains a graphical net. The only task, this net is solving, is to be visible. It should be solution in overriding OnPaint method, but it doesn't. This code: protected override void OnPaint(System.Windows.Forms.PaintEventArgs e) { base.OnPaint(e); ...//drawing a line } gives me RichTextBox without of text This code: protected override void WndProc(ref System.Windows.Forms.Message m) { base.WndProc(ref m); if (m.Msg == 15) { Graphics g = this.CreateGraphics(); g.DrawLine(new Pen(Color.White, 1), new Point(0, 0), new Point(400, 400)); } } sometimes draws extra lines Actually since these two ways don't work, I don't know what to try. Waiting for your advices :) BR Dmitry P.S. I’ve heard a lot about great opportunities of WPF, but I’m not really common with this technology and don’t know what to start with. P.P.S. Sorry for my English, it’s not my natural language.

  • Localizing DataAnnotations Custom Validator

    - by Gabe G
    Hello SO, I'm currently working in an MVC 2 app which has to have everything localized in n-languages (currently 2, none of them english btw). I validate my model classes with DataAnnotations but when I wanted to validate a DateTime field found out that the DataTypeAttribute returns always true, no matter it was a valid date or not (that's because when I enter a random string "foo", the IsValid() method checks against "01/01/0001 ", dont know why). Decided to write my own validator extending ValidationAtribute class: public class DateTimeAttribute : ValidationAttribute { public override bool IsValid(object value) { DateTime result; if (value.ToString().Equals("01/01/0001 0:00:00")) { return false; } return DateTime.TryParse(value.ToString(), out result); } } Now it checks OK when is valid and when it's not, but my problem starts when I try to localize it: [Required(ErrorMessageResourceType = typeof(MSG), ErrorMessageResourceName = "INS_DATA_Required")] [CustomValidation.DateTime(ErrorMessageResourceType = typeof(MSG), ErrorMessageResourceName = "INS_DATA_DataType")] public DateTime INS_DATA { get; set; } If I put nothing in the field I get a localized MSG (MSG being my resource class) for the key=INS_DATA_Required but if I put a bad-formatted date I get the "The value 'foo' is not valid for INS_DATA" default message and not the localized MSG. What am I misssing?

  • How to traverse the item in the collection in a List or Observable collection?

    - by Ashish Ashu
    I have a collection that is binded to my Listview. I have provided options to user to "move up" "move down" the selected item in the list view. I have binded the selected item of the listview to my viewmodel, hence I get the item in the collection on which user want to do the operation. I have attached "move up" "move down" commands in my viewmodel. I want what is the best way to move up and down in the collection in the collection which is reflected in the list view. Please suggest.

    Hi All, Is it possible to set thickness property of SolidColorBrush.

Is it possible?

  • C# - Regular Expression validating Date and Hour

    - by nettguy
    I receive Date and time from CSV file The received Date format is YYYMMDD (string) (there is no ":" ,"-","/" to separate Year month and date). The received time format is HH:MM (24 Hour clock). I have to validate both so that (example) (i) 000011990 could be invalidated for date (ii) 77:90 could be invalidated for time. The question is , Regular expression is the right candidate for do so (or) is there any other way to achieve it?

  • Access to variables in an asp.net user control vs an include file

    - by user204588
    I've asked this question before but couldn't get the answer I was looking for so I'm going to try it again. I'm translating pages from old asp to asp.net and I don't want to do this any other way so I really just want to know if this can be done. In asp, I'd assign a variable on one page <% myVar = "something" %> I could assign many variables here and then use an include <!--#include file="Test2.aspx"--> then in test2 file, I could access all the variables without having to pass all the variables into the control or declaring them again, like <% myVar = "something else" %> I want to do this the dot net way but I have some thirty variables on the page and i don't want to pass a bunch into the user control and I don't want to have to keep declaring the same variables. All I really want to know is if there is some way to replicate the behavior above in asp.net?

  • Looking for a component (.NET or COM/ActiveX) that can play AVI files in a WinForms app

    - by MusiGenesis
    I'm looking for something like the Windows Media Player control that can be hosted on a form. The WMP doesn't work for me because I need a control that can play a continuously-appended playlist of AVI files in sequence, so that the transition from one file to the next happens seamlessly (i.e. without any glitches or pauses in the video and audio). With WMP, there's always a delay between files of half a second or so. Does anyone know of a control (it can be either commercial or open-source) that can do this? I assume anything like this wraps DirectX, and that's OK too.

  • Subcontrols not visible in custom control derived from another control

    - by Gacek
    I'm trying to create a custom control by deriving from a ZedGraphControl I need to add a ProgressBar to the control, but I encountered some problems. When I create a custom control and add both, ZedGraphCOntrol and ProgressBar to it, everything is OK: MyCustomControl { ZedGraphControl ProgressBar } All elemnets are visible and working as expected. But I need to derive from ZGC and when I add a progress bar as a subcontrol of ZedGraphControl: MyCustomControl : ZedGRaphControl { ProgressBar } The progress bar is not visible. Is there any way to force the visibility of ProgressBar? Is it possible, that ZedGraphControl is not displaying its subcontrols? I tried do the same thing with a simple button and it's also not being displayed.

  • WPF, C# - Making Intellisense/Autocomplete list, fastest way to filter list of strings

    - by user559548
    Hello everyone, I'm writing an Intellisense/Autocomplete like the one you find in Visual Studio. It's all fine up until when the list contains probably 2000+ items. I'm using a simple LINQ statement for doing the filtering: var filterCollection = from s in listCollection where s.FilterValue.IndexOf(currentWord, StringComparison.OrdinalIgnoreCase) >= 0 orderby s.FilterValue select s; I then assign this collection to a WPF Listbox's ItemSource, and that's the end of it, works fine. Noting that, the Listbox is also virtualised as well, so there will only be at most 7-8 visual elements in memory and in the visual tree. However the caveat right now is that, when the user types extremely fast in the richtextbox, and on every key up I execute the filtering + binding, there's this semi-race condition, or out of sync filtering, like the first key stroke's filtering could still be doing it's filtering or binding work, while the fourth key stroke is also doing the same. I know I could put in a delay before applying the filter, but I'm trying to achieve a seamless filtering much like the one in Visual Studio. I'm not sure where my problem exactly lies, so I'm also attributing it to IndexOf's string operation, or perhaps my list of string's could be optimised in some kind of index, that could speed up searching. Any suggestions of code samples are much welcomed. Thanks.

  • Flex Force Decimal

    - by babyangel86
    Hi, I'm looking for a regex or a way to format the NumberValidator so that only decimal places are allowed. The domain="real" allows you to put integer values, but I need to force the user to but in 2.0 if they want an integer. This is because they pass through a Castor mapping file, it complains if it gets an integer when it expects a decimal. I dont want to restrict the number of decimal places, just insist that there must be a point, and a number after it. Any help would be much appreciated.

  • Retrieve Table Row Index of Current Row

    Hi Everyone, I am trying to validate a text input when it loses focus. I would like to know which row of the table it is in. This is what I have so far and it keeps coming back as undefined. Any ideas? $("div#step-2 fieldset table tbody tr td input").blur(function() { var tableRow = $(this).parent().parent(); if ($.trim($(this).val()) == "") { $(this).addClass("invalid"); alert(tableRow.rowIndex); $(this).val(""); } else { $(this).removeClass("invalid"); checkTextChanges(); } });

  • Does using the converting input from HTML forms into htmlentities protect attacks invoving JavaScrip

    - by racl101
    Hi everyone, I was wondering if converting POST input from an HTML form into html entities, (via the PHP function htmlentities() or using the FILTER_SANITIZE_SPECIAL_CHARS constant in tandem with the filter_input() PHP function ), will help defend against any attacks where a user attempts to insert any JavaScript code inside the form field or if there's any other PHP based function or tactic I should employ to create a safe HTML form experience? Sorry for the loaded run-on sentence question but that's the best I could word it in a hurry. Any responses would be greatly appreciated and thanks to all in advance. racl101
