  • Unity Configuration and Same Assembly

    - by tyndall
    I'm currently getting an error trying to resolve my IDataAccess class. The value of the property 'type' cannot be parsed. The error is: Could not load file or assembly 'TestProject' or one of its dependencies. The system cannot find the file specified. (C:\Source\TestIoC\src\TestIoC\TestProject\bin\Debug\TestProject.vshost.exe.config line 14) This is inside a WPF Application project. What is the correct syntax to refer to the Assembly you are currently in? is there a way to do this? I know in a larger solution I would be pulling Types from seperate assemblies so this might not be an issue. But what is the right way to do this for a small self-contained test project. Note: I'm only interested in doing the XML config at this time, not the C# (in code) config. UPDATE: see all comments My XML config: <configuration> <configSections> <section name="unity" type="Microsoft.Practices.Unity.Configuration.UnityConfigurationSection, Microsoft.Practices.Unity.Configuration" /> </configSections> <unity> <typeAliases> <!-- Lifetime manager types --> <typeAlias alias="singleton" type="Microsoft.Practices.Unity.ContainerControlledLifetimeManager, Microsoft.Practices.Unity" /> <typeAlias alias="external" type="Microsoft.Practices.Unity.ExternallyControlledLifetimeManager, Microsoft.Practices.Unity" /> <typeAlias alias="IDataAccess" type="TestProject.IDataAccess, TestProject" /> <typeAlias alias="DataAccess" type="TestProject.DataAccess, TestProject" /> </typeAliases> <containers> <container name="Services"> <types> <type type="IDataAccess" mapTo="DataAccess" /> </types> </container> </containers> </unity> </configuration>

  • Financial Charts / Graphs in Ruby or Python

    - by Eric the Red
    What are my best options for creating a financial open-high-low-close (OHLC) chart in a high level language like Ruby or Python? While there seem to be a lot of options for graphing, I haven't seen any gems or eggs with this kind of chart. http://en.wikipedia.org/wiki/Open-high-low-close_chart (but I don't need the moving average or Bollinger bands) JFreeChart can do this in Java, but I'd like to make my codebase as small and simple as possible. Thanks!

  • How to insert a new row between two existing rows of MsChart?

    - by Meera
    Hi..Is there any provision to insert a new row between two existing rows of a rangebar chart? If so,please suggest me.Example:Adding a new row at the position where xaxis label equals 2 so that we will get a new row with the axis label as 3(normally in range bar chart type,xaxis representations are taken as yaxis,so here "xaxis label" denotes "yaxis label") .How can i do this?

  • Getting unhandled exception when DataTemplate is created dynamically using Silverlight 3.0

    - by Bhaskar
    Requirement is to create a reusable multi-select combobox custom control. To accomplish this, I am creating the DataTemplate dynamically through code and set the combobox ItemTemplate. I am able to load the datatemplate dynamically and set the ItemTemplate, but getting unhandled exception (code: 7054) when combobox is selected.

  • How do I export charts from Excel as graphics

    - by user83266
    I've got a series of Excel spreadsheets, each with at least one page of data and one page of a chart created from the data. I need to capture ( not regenerate from the data ) the existing chart as a web friendly image. Is this possible via Java or .Net? I know the POI stuff (Java) won't do it (or so I'm told, haven't tried it myself).

  • Alter highchart output to display start - end date

    - by php_d
    I currently have the following highchart which display a start date and outputs the values for the next 31 days of data. Does anyone know how I may improve on this to include and end date so that I can filter the data by smaller specific amounts? On the x-axis I am also trying to only display labels that have data attached to them and hide any others. Any help is appreciated. My code is as follows: <script type="text/javascript"> var chart; $(document).ready(function() { chart = new Highcharts.Chart({ chart: { renderTo: 'container', type: 'line', marginRight: 130, marginBottom: 25 }, title: { text: '<?php echo $type ?>', x: -20 //center }, xAxis: { categories: [ <?php $start = $_POST["dateStart"]; $dates = array(); for ($i = 0, $days = date('t', strtotime($start)); $i < $days; ++$i) { $dates[] = date('Y-m-d', strtotime($start . ' + ' . $i . ' day')); } echo "'" . implode("', '", $dates) . "'"; ?> ] }, yAxis: { title: { text: 'Total Amount' }, plotLines: [{ value: 0, width: 1, color: '#808080' }] }, tooltip: { formatter: function() { return '<b>'+ this.series.name +'</b><br/>'+ this.x +': '+ this.y; } }, legend: { layout: 'vertical', align: 'right', verticalAlign: 'top', x: -10, y: 100, borderWidth: 0 }, series: [ <?php foreach ($array as $legend => $data) { echo '{'; echo "name: '" . $legend . "',"; $values = array(); for ($i = 0; $i < $days; ++$i) { $date = date('Y-m-d', strtotime($start . ' + ' . $i . ' day')); $values[] = isset($data[$date]) ? $data[$date] : 0; } echo 'data: [' . implode(', ', $values) . '],'; echo '},'; } ?> ] }); }); Thanks

  • set highchart margin

    - by user1392330
    I have built a a higcharts charts and I am displaying them one at a time on mouseover. The jquery creates a floting div (depending on the cursor) with a border line 1px solid black and then the highchart method is being called to draw the chart. The thing is that highcharts exceed and left and bottom border is not shown. I tired 'margin' : chart: { renderTo: 'graph', defaultSeriesType: 'line', zoomType: 'x', margin: [ 10, 10, 10, 10] }, and still it does the same thing.

  • Importing Excel spreadsheet data into existing Access DB

    - by Keeb13r
    I've designed an Access 2003 DB with 3 tables: APPLICATIONS, SERVERS, and INSTALLATIONS. Records in the APPLICATIONS and SERVERS tables are uniquely identified by a synthetic primary key (in Access, an "auto number"). The INSTALLATIONS table is essentially a mapping table between APPLICATIONS and SERVERS: it's a list of records of which applications are installed on which servers. A record in the INSTALLATIONS table is also identified by a synthetic primary key, and it consists of an APPLICATION_ID and SERVER_ID for the records in their respective tables. I have an Excel 2003 spreadsheet I would like to import into this database, but it's proving difficult. The spreadsheet is made up of several tabs/worksheets, each one representing a server with its own listing of installed applications. I'm not sure how to proceed with an import - the "Get External Data -- Import" feature in Access has an import "In an Existing Table" option, but it's greyed out. I'm also unsure how I build the relationships between applications and servers for importing records into the INSTALLATIONS table. I had previously fooled around with adding some security to the Access DB file. I think I removed everything but perhaps I didn't and that's causing the problem? Some sample data from the Excel spreadsheet: SERVER101 * Adobe Reader 9 * BMC Remedy User 7.0 * HostExplorer 2008 * Microsoft Office 2003 * Microsoft Office 2007 * Notepad++ SERVER102 * Adobe Reader 9 * DameWare Mini Remote Control * Microsoft Office 2003 * Microsoft .NET Framework 3.5 SP1 * Oracle 9.2 SERVER103 * AWDView * EXTRA! Personal Client 32-bit * Microsoft Office 2003 * Microsoft .NET Framework 3.5 SP1 * Snagit 9.1 * WinZip 12.1 The Access DB design is very simple: APPLICATION * APPLICATION_ID (autonumber) * APPLICATION_NAME (varchar) SERVER * SERVER_ID (autonumber) * SERVER_NAME (varchar) INSTALLATION * INSTALLATION_ID (autonumber) * APPLICATION_ID (number) * SERVER_ID (number)

  • Flex bug?? Get messed up stacked ColumnChart with type="100%"

    - by Nir
    I am trying to do a stacked Column chart with type="100%" and a mixture of positive and negative values. When all the values are positive, is functions well, but when negative numbers come to the game, it looks totally messed up. When I also look at Adobe documentation (look here), I see the following code for stacked column chart involving negative numbers: <?xml version="1.0"?> <!-- charts/StackedNegative.mxml --> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"> <mx:Script><![CDATA[ import mx.collections.ArrayCollection; [Bindable] public var expenses:ArrayCollection = new ArrayCollection([ {Month:"Jan", Profit:-2000, Expenses:-1500}, {Month:"Feb", Profit:1000, Expenses:-200}, {Month:"Mar", Profit:1500, Expenses:-500} ]); ]]></mx:Script> <mx:Panel title="Column Chart"> <mx:ColumnChart id="myChart" dataProvider="{expenses}" showDataTips="true"> <mx:horizontalAxis> <mx:CategoryAxis dataProvider="{expenses}" categoryField="Month" /> </mx:horizontalAxis> <mx:series> <mx:ColumnSet type="stacked" allowNegativeForStacked="true"> <mx:series> <mx:ColumnSeries xField="Month" yField="Profit" displayName="Profit" /> <mx:ColumnSeries xField="Month" yField="Expenses" displayName="Expenses" /> </mx:series> </mx:ColumnSet> </mx:series> </mx:ColumnChart> <mx:Legend dataProvider="{myChart}"/> </mx:Panel> </mx:Application> It works fine. But try to change: <mx:ColumnSet type="stacked" allowNegativeForStacked="true"> to: <mx:ColumnSet type="100%" allowNegativeForStacked="true"> and you'll see that it doesn't on January data, where both values are negative, the chart shows as if they are positive, and on the other two where one value is positive and the other is negative, it shows only the positive part as 100%... Isn't it a Flex Bug? I have my own case with such data and it behaves wrong the same way. I'd expect that if it has 800 stacked on -200, it will show 80% up and 20% down, totalling 100%. BTW: Using Flex 4, though these are all mx components. Thanks a lot and regards from Berlin, Germany, Nir.

  • Need Google Map InfoWindow Hyperlink to Open Content in Overlay (Fusion Table Usage)

    - by McKev
    I have the following code established to render the map in my site. When the map is clicked, the info window pops up with a bunch of content including a hyperlink to open up a website with a form in it. I would like to utilize a function like fancybox to open up this link "form" in an overlay. I have read that fancybox doesn't support calling the function from within an iframe, and was wondering if there was a way to pass the link data to the DOM and trigger the fancybox (or another overlay option) in another way? Maybe a callback trick - any tips would be much appreciated! <style> #map-canvas { width:850px; height:600px; } </style> <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=true"></script> <script src="http://gmaps-utility-gis.googlecode.com/svn/trunk/fusiontips/src/fusiontips.js" type="text/javascript"></script> <script type="text/javascript"> var map; var tableid = "1nDFsxuYxr54viD_fuH7fGm1QRZRdcxFKbSwwRjk"; var layer; var initialLocation; var browserSupportFlag = new Boolean(); var uscenter = new google.maps.LatLng(37.6970, -91.8096); function initialize() { map = new google.maps.Map(document.getElementById('map-canvas'), { zoom: 4, mapTypeId: google.maps.MapTypeId.ROADMAP }); layer = new google.maps.FusionTablesLayer({ query: { select: "'Geometry'", from: tableid }, map: map }); //http://gmaps-utility-gis.googlecode.com/svn/trunk/fusiontips/docs/reference.html layer.enableMapTips({ select: "'Contact Name','Contact Title','Contact Location','Contact Phone'", from: tableid, geometryColumn: 'Geometry', suppressMapTips: false, delay: 500, tolerance: 8 }); ; // Try W3C Geolocation (Preferred) if(navigator.geolocation) { browserSupportFlag = true; navigator.geolocation.getCurrentPosition(function(position) { initialLocation = new google.maps.LatLng(position.coords.latitude,position.coords.longitude); map.setCenter(initialLocation); //Custom Marker var pinColor = "A83C0A"; var pinImage = new google.maps.MarkerImage("http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|" + pinColor, new google.maps.Size(21, 34), new google.maps.Point(0,0), new google.maps.Point(10, 34)); var pinShadow = new google.maps.MarkerImage("http://chart.apis.google.com/chart?chst=d_map_pin_shadow", new google.maps.Size(40, 37), new google.maps.Point(0, 0), new google.maps.Point(12, 35)); new google.maps.Marker({ position: initialLocation, map: map, icon: pinImage, shadow: pinShadow }); }, function() { handleNoGeolocation(browserSupportFlag); }); } // Browser doesn't support Geolocation else { browserSupportFlag = false; handleNoGeolocation(browserSupportFlag); } function handleNoGeolocation(errorFlag) { if (errorFlag == true) { //Geolocation service failed initialLocation = uscenter; } else { //Browser doesn't support geolocation initialLocation = uscenter; } map.setCenter(initialLocation); } } google.maps.event.addDomListener(window, 'load', initialize); </script>

  • Show all datatips for a single lineseries

    - by rchung77
    I'm trying to figure out if there is a way to show all datatips for a single lineseries in a Flex 3 linechart. This chart will have multiple lines and the functionality we're looking for is when a user hovers over a line, show all datatips associated with just that series. Any help would be appreciated. showAllDataTips will not work in this case as it will display all datatips on the chart. Thanks! Rich

  • C: performance of assignments, binary operations, et cetera...

    - by Shinka
    I've heard many things about performance in C; casting is slow compared to normal assignments, functional call is slow, binary operation are much faster than normal operations, et cetera... I'm sure some of those things are specific to the architecture, and compiler optimization might make a huge difference, but I would like to see a chart to get a general idea what I should do and what I should avoid to write high-performance programs. Is there such a chart (or a website, a book, anything) ?

  • Creating a fixed axis for Silverlight Toolkit charts

    - by Bill Jeeves
    Every example I see of a series in a Silverlight chart fromt he toolkit has a binding for bothe IndependentValueBinding and DependentValueBinding. In my code I want a fixed axis for the categories (Independent) - so every value get's "X" perhaps. Is there a way to do this? Essentially I have ten bar series in one chart and I want them all to sit together. It seems silly to create a new class to hold them in just so I can add a string property for the axis name.

  • How should I smooth the transition between these two states in flex/flashbuilder

    - by Joshua
    I have an item in which has two states, best described as open and closed, and they look like this: and And what I'd like to do is is smooth the transition between one state and the other, effectively by interpolating between the two points in a smooth manner (sine) to move the footer/button-block and then fade in the pie chart. However this is apparently beyond me and after wrestling with my inability to do so for an hour+ I'm posting it here :D So my transition block looks as follows <s:transitions> <s:Transition id="TrayTrans" fromState="*" toState="*"> <s:Sequence> <s:Move duration="400" target="{footer}" interpolator="{Sine}"/> <s:Fade duration="300" targets="{body}"/> </s:Sequence> </s:Transition> <s:Transition> <s:Rotate duration="3000" /> </s:Transition> </s:transitions> where {body} refers to the pie chart and {footer} refers to the footer/button-block. However this doesn't work so I don't really know what to do... Additional information which may be beneficial: The body block is always of fixed height (perhaps of use for the Xby variables in some effects?). It needs to work in both directions. Oh and the Sine block is defined above in declarations just as <s:Sine id="Sine">. Additionally! How would I go about setting the pie chart to rotate continually using these transition blocks? (this would occur without the labels on) Or is that the wrong way to go about it as it's not a transition as such? The effect I'm after is one where the pie chart rotates slowly without labels prior to a selection of a button below, but on selection the rotation stops and labels appear... Thanks a lot in advance! And apologies on greyscale, but I can't really decide on a colour scheme. Any suggestions welcome.

  • Line graph disappears after new line is added

    - by tonystinge
    I am having trouble uploading a large .csv file to my HIGHCHART graph. I've been able to graph an 85KB up to 1486 lines by 9 (I) columns.

  • Programatically add UserControl with events

    - by schaermu
    Hi everybody I need to add multiple user controls to a panel for further editing of the contained data. My user control contains some panels, dropdown lists and input elements, which are populated in the user control's Page_Load event. protected void Page_Load(object sender, EventArgs e) { // populate comparer ddl from enum string[] enumNames = Enum.GetNames(typeof (SearchComparision)); var al = new ArrayList(); for (int i = 0; i < enumNames.Length; i++) al.Add(new {Value = i, Name = enumNames[i]}); scOperatorSelection.DataValueField = "Value"; scOperatorSelection.DataTextField = "Name"; ... The data to be displayed is added to the user control as a Field, defined above Page_Load. The signature of the events is the following: public delegate void ControlStateChanged(object sender, SearchCriteriaEventArgs eventArgs); public event ControlStateChanged ItemUpdated; public event ControlStateChanged ItemRemoved; public event ControlStateChanged ItemAdded; The update button on the user control triggers the following method: protected void UpdateCriteria(object sender, EventArgs e) { var searchCritCtl = (SearchCriteria) sender; var scEArgs = new SearchCriteriaEventArgs { TargetCriteria = searchCritCtl.CurrentCriteria.CriteriaId, SearchComparision = ParseCurrentComparer(searchCritCtl.scOperatorSelection.SelectedValue), SearchField = searchCritCtl.scFieldSelection.SelectedValue, SearchValue = searchCritCtl.scFilterValue.Text, ClickTarget = SearchCriteriaClickTarget.Update }; if (ItemUpdated != null) ItemUpdated(this, scEArgs); } The rendering page fetches the data objects from a storage backend and displays it in it's Page_Load event. This is the point where it starts getting tricky: i connect to the custom events! int idIt = 0; foreach (var item in _currentSearch.Items) { SearchCriteria sc = (SearchCriteria)LoadControl("~/content/controls/SearchCriteria.ascx"); sc.ID = "scDispCtl_" + idIt; sc.ControlMode = SearchCriteriaMode.Display; sc.CurrentCriteria = item; sc.ItemUpdated += CriteriaUpdated; sc.ItemRemoved += CriteriaRemoved; pnlDisplayCrit.Controls.Add(sc); idIt++; } When first rendering the page, everything is displayed fine, i get all my data. When i trigger an update event, the user control event is fired correctly, but all fields and controls of the user control are NULL. After a bit of research, i had to come to the conclusion that the event is fired before the controls are initialized... Is there any way to prevent such behavior / to override the page lifecycle somehow? I cannot initialize the user controls in the page's Init-event, because i have to access the Session-Store (not initialized in Page_Init). Any advice is welcome... EDIT: Since we hold all criteria informations in the storage backend (including the count of criteria) and that store uses the userid from the session, we cannot use Page_Init... just for clarification EDIT #2: I managed to get past some of the problems. Since i'm now using simple types, im able to bind all the data declaratively (using a repeater with a simple ItemTemplate). It is bound to the control, they are rendered in correct fashion. On Postback, all the data is rebound to the user control, data is available in the OnDataBinding and OnLoad events, everything looks fine. But as soon it enters the real event (bound to the button control of the user control), all field values are lost somehow... Does anybody know, how the page lifecycle continues to process the request after Databinding/Loading ? I'm going crazy about this issue...

  • Understanding Request Validation in ASP.NET MVC 3

    - by imran_ku07
         Introduction:             A fact that you must always remember "never ever trust user inputs". An application that trusts user inputs may be easily vulnerable to XSS, XSRF, SQL Injection, etc attacks. XSS and XSRF are very dangerous attacks. So to mitigate these attacks ASP.NET introduced request validation in ASP.NET 1.1. During request validation, ASP.NET will throw HttpRequestValidationException: 'A potentially dangerous XXX value was detected from the client', if he found, < followed by an exclamation(like <!) or < followed by the letters a through z(like <s) or & followed by a pound sign(like &#123) as a part of query string, posted form and cookie collection. In ASP.NET 4.0, request validation becomes extensible. This means that you can extend request validation. Also in ASP.NET 4.0, by default request validation is enabled before the BeginRequest phase of an HTTP request. ASP.NET MVC 3 moves one step further by making request validation granular. This allows you to disable request validation for some properties of a model while maintaining request validation for all other cases. In this article I will show you the use of request validation in ASP.NET MVC 3. Then I will briefly explain the internal working of granular request validation.       Description:             First of all create a new ASP.NET MVC 3 application. Then create a simple model class called MyModel,     public class MyModel { public string Prop1 { get; set; } public string Prop2 { get; set; } }             Then just update the index action method as follows,   public ActionResult Index(MyModel p) { return View(); }             Now just run this application. You will find that everything works just fine. Now just append this query string ?Prop1=<s to the url of this application, you will get the HttpRequestValidationException exception.           Now just decorate the Index action method with [ValidateInputAttribute(false)],   [ValidateInput(false)] public ActionResult Index(MyModel p) { return View(); }             Run this application again with same query string. You will find that your application run without any unhandled exception.           Up to now, there is nothing new in ASP.NET MVC 3 because ValidateInputAttribute was present in the previous versions of ASP.NET MVC. Any problem with this approach? Yes there is a problem with this approach. The problem is that now users can send html for both Prop1 and Prop2 properties and a lot of developers are not aware of it. This means that now everyone can send html with both parameters(e.g, ?Prop1=<s&Prop2=<s). So ValidateInput attribute does not gives you the guarantee that your application is safe to XSS or XSRF. This is the reason why ASP.NET MVC team introduced granular request validation in ASP.NET MVC 3. Let's see this feature.           Remove [ValidateInputAttribute(false)] on Index action and update MyModel class as follows,   public class MyModel { [AllowHtml] public string Prop1 { get; set; } public string Prop2 { get; set; } }             Note that AllowHtml attribute is only decorated on Prop1 property. Run this application again with ?Prop1=<s query string. You will find that your application run just fine. Run this application again with ?Prop1=<s&Prop2=<s query string, you will get HttpRequestValidationException exception. This shows that the granular request validation in ASP.NET MVC 3 only allows users to send html for properties decorated with AllowHtml attribute.            Sometimes you may need to access Request.QueryString or Request.Form directly. You may change your code as follows,   [ValidateInput(false)] public ActionResult Index() { var prop1 = Request.QueryString["Prop1"]; return View(); }             Run this application again, you will get the HttpRequestValidationException exception again even you have [ValidateInput(false)] on your Index action. The reason is that Request flags are still not set to unvalidate. I will explain this later. For making this work you need to use Unvalidated extension method,     public ActionResult Index() { var q = Request.Unvalidated().QueryString; var prop1 = q["Prop1"]; return View(); }             Unvalidated extension method is defined in System.Web.Helpers namespace . So you need to add using System.Web.Helpers; in this class file. Run this application again, your application run just fine.             There you have it. If you are not curious to know the internal working of granular request validation then you can skip next paragraphs completely. If you are interested then carry on reading.             Create a new ASP.NET MVC 2 application, then open global.asax.cs file and the following lines,     protected void Application_BeginRequest() { var q = Request.QueryString; }             Then make the Index action method as,    [ValidateInput(false)] public ActionResult Index(string id) { return View(); }             Please note that the Index action method contains a parameter and this action method is decorated with [ValidateInput(false)]. Run this application again, but now with ?id=<s query string, you will get HttpRequestValidationException exception at Application_BeginRequest method. Now just add the following entry in web.config,   <httpRuntime requestValidationMode="2.0"/>             Now run this application again. This time your application will run just fine. Now just see the following quote from ASP.NET 4 Breaking Changes,   In ASP.NET 4, by default, request validation is enabled for all requests, because it is enabled before the BeginRequest phase of an HTTP request. As a result, request validation applies to requests for all ASP.NET resources, not just .aspx page requests. This includes requests such as Web service calls and custom HTTP handlers. Request validation is also active when custom HTTP modules are reading the contents of an HTTP request.             This clearly state that request validation is enabled before the BeginRequest phase of an HTTP request. For understanding what does enabled means here, we need to see HttpRequest.ValidateInput, HttpRequest.QueryString and HttpRequest.Form methods/properties in System.Web assembly. Here is the implementation of HttpRequest.ValidateInput, HttpRequest.QueryString and HttpRequest.Form methods/properties in System.Web assembly,     public NameValueCollection Form { get { if (this._form == null) { this._form = new HttpValueCollection(); if (this._wr != null) { this.FillInFormCollection(); } this._form.MakeReadOnly(); } if (this._flags[2]) { this._flags.Clear(2); this.ValidateNameValueCollection(this._form, RequestValidationSource.Form); } return this._form; } } public NameValueCollection QueryString { get { if (this._queryString == null) { this._queryString = new HttpValueCollection(); if (this._wr != null) { this.FillInQueryStringCollection(); } this._queryString.MakeReadOnly(); } if (this._flags[1]) { this._flags.Clear(1); this.ValidateNameValueCollection(this._queryString, RequestValidationSource.QueryString); } return this._queryString; } } public void ValidateInput() { if (!this._flags[0x8000]) { this._flags.Set(0x8000); this._flags.Set(1); this._flags.Set(2); this._flags.Set(4); this._flags.Set(0x40); this._flags.Set(0x80); this._flags.Set(0x100); this._flags.Set(0x200); this._flags.Set(8); } }             The above code indicates that HttpRequest.QueryString and HttpRequest.Form will only validate the querystring and form collection if certain flags are set. These flags are automatically set if you call HttpRequest.ValidateInput method. Now run the above application again(don't forget to append ?id=<s query string in the url) with the same settings(i.e, requestValidationMode="2.0" setting in web.config and Application_BeginRequest method in global.asax.cs), your application will run just fine. Now just update the Application_BeginRequest method as,   protected void Application_BeginRequest() { Request.ValidateInput(); var q = Request.QueryString; }             Note that I am calling Request.ValidateInput method prior to use Request.QueryString property. ValidateInput method will internally set certain flags(discussed above). These flags will then tells the Request.QueryString (and Request.Form) property that validate the query string(or form) when user call Request.QueryString(or Request.Form) property. So running this application again with ?id=<s query string will throw HttpRequestValidationException exception. Now I hope it is clear to you that what does requestValidationMode do. It just tells the ASP.NET that not invoke the Request.ValidateInput method internally before the BeginRequest phase of an HTTP request if requestValidationMode is set to a value less than 4.0 in web.config. Here is the implementation of HttpRequest.ValidateInputIfRequiredByConfig method which will prove this statement(Don't be confused with HttpRequest and Request. Request is the property of HttpRequest class),    internal void ValidateInputIfRequiredByConfig() { ............................................................... ............................................................... ............................................................... ............................................................... if (httpRuntime.RequestValidationMode >= VersionUtil.Framework40) { this.ValidateInput(); } }              Hopefully the above discussion will clear you how requestValidationMode works in ASP.NET 4. It is also interesting to note that both HttpRequest.QueryString and HttpRequest.Form only throws the exception when you access them first time. Any subsequent access to HttpRequest.QueryString and HttpRequest.Form will not throw any exception. Continuing with the above example, just update Application_BeginRequest method in global.asax.cs file as,   protected void Application_BeginRequest() { try { var q = Request.QueryString; var f = Request.Form; } catch//swallow this exception { } var q1 = Request.QueryString; var f1 = Request.Form; }             Without setting requestValidationMode to 2.0 and without decorating ValidateInput attribute on Index action, your application will work just fine because both HttpRequest.QueryString and HttpRequest.Form will clear their flags after reading HttpRequest.QueryString and HttpRequest.Form for the first time(see the implementation of HttpRequest.QueryString and HttpRequest.Form above).           Now let's see ASP.NET MVC 3 granular request validation internal working. First of all we need to see type of HttpRequest.QueryString and HttpRequest.Form properties. Both HttpRequest.QueryString and HttpRequest.Form properties are of type NameValueCollection which is inherited from the NameObjectCollectionBase class. NameObjectCollectionBase class contains _entriesArray, _entriesTable, NameObjectEntry.Key and NameObjectEntry.Value fields which granular request validation uses internally. In addition granular request validation also uses _queryString, _form and _flags fields, ValidateString method and the Indexer of HttpRequest class. Let's see when and how granular request validation uses these fields.           Create a new ASP.NET MVC 3 application. Then put a breakpoint at Application_BeginRequest method and another breakpoint at HomeController.Index method. Now just run this application. When the break point inside Application_BeginRequest method hits then add the following expression in quick watch window, System.Web.HttpContext.Current.Request.QueryString. You will see the following screen,                                              Now Press F5 so that the second breakpoint inside HomeController.Index method hits. When the second breakpoint hits then add the following expression in quick watch window again, System.Web.HttpContext.Current.Request.QueryString. You will see the following screen,                            First screen shows that _entriesTable field is of type System.Collections.Hashtable and _entriesArray field is of type System.Collections.ArrayList during the BeginRequest phase of the HTTP request. While the second screen shows that _entriesTable type is changed to Microsoft.Web.Infrastructure.DynamicValidationHelper.LazilyValidatingHashtable and _entriesArray type is changed to Microsoft.Web.Infrastructure.DynamicValidationHelper.LazilyValidatingArrayList during executing the Index action method. In addition to these members, ASP.NET MVC 3 also perform some operation on _flags, _form, _queryString and other members of HttpRuntime class internally. This shows that ASP.NET MVC 3 performing some operation on the members of HttpRequest class for making granular request validation possible.           Both LazilyValidatingArrayList and LazilyValidatingHashtable classes are defined in the Microsoft.Web.Infrastructure assembly. You may wonder why their name starts with Lazily. The fact is that now with ASP.NET MVC 3, request validation will be performed lazily. In simple words, Microsoft.Web.Infrastructure assembly is now taking the responsibility for request validation from System.Web assembly. See the below screens. The first screen depicting HttpRequestValidationException exception in ASP.NET MVC 2 application while the second screen showing HttpRequestValidationException exception in ASP.NET MVC 3 application.   In MVC 2:                 In MVC 3:                          The stack trace of the second screenshot shows that Microsoft.Web.Infrastructure assembly (instead of System.Web assembly) is now performing request validation in ASP.NET MVC 3. Now you may ask: where Microsoft.Web.Infrastructure assembly is performing some operation on the members of HttpRequest class. There are at least two places where the Microsoft.Web.Infrastructure assembly performing some operation , Microsoft.Web.Infrastructure.DynamicValidationHelper.GranularValidationReflectionUtil.GetInstance method and Microsoft.Web.Infrastructure.DynamicValidationHelper.ValidationUtility.CollectionReplacer.ReplaceCollection method, Here is the implementation of these methods,   private static GranularValidationReflectionUtil GetInstance() { try { if (DynamicValidationShimReflectionUtil.Instance != null) { return null; } GranularValidationReflectionUtil util = new GranularValidationReflectionUtil(); Type containingType = typeof(NameObjectCollectionBase); string fieldName = "_entriesArray"; bool isStatic = false; Type fieldType = typeof(ArrayList); FieldInfo fieldInfo = CommonReflectionUtil.FindField(containingType, fieldName, isStatic, fieldType); util._del_get_NameObjectCollectionBase_entriesArray = MakeFieldGetterFunc<NameObjectCollectionBase, ArrayList>(fieldInfo); util._del_set_NameObjectCollectionBase_entriesArray = MakeFieldSetterFunc<NameObjectCollectionBase, ArrayList>(fieldInfo); Type type6 = typeof(NameObjectCollectionBase); string str2 = "_entriesTable"; bool flag2 = false; Type type7 = typeof(Hashtable); FieldInfo info2 = CommonReflectionUtil.FindField(type6, str2, flag2, type7); util._del_get_NameObjectCollectionBase_entriesTable = MakeFieldGetterFunc<NameObjectCollectionBase, Hashtable>(info2); util._del_set_NameObjectCollectionBase_entriesTable = MakeFieldSetterFunc<NameObjectCollectionBase, Hashtable>(info2); Type targetType = CommonAssemblies.System.GetType("System.Collections.Specialized.NameObjectCollectionBase+NameObjectEntry"); Type type8 = targetType; string str3 = "Key"; bool flag3 = false; Type type9 = typeof(string); FieldInfo info3 = CommonReflectionUtil.FindField(type8, str3, flag3, type9); util._del_get_NameObjectEntry_Key = MakeFieldGetterFunc<string>(targetType, info3); Type type10 = targetType; string str4 = "Value"; bool flag4 = false; Type type11 = typeof(object); FieldInfo info4 = CommonReflectionUtil.FindField(type10, str4, flag4, type11); util._del_get_NameObjectEntry_Value = MakeFieldGetterFunc<object>(targetType, info4); util._del_set_NameObjectEntry_Value = MakeFieldSetterFunc(targetType, info4); Type type12 = typeof(HttpRequest); string methodName = "ValidateString"; bool flag5 = false; Type[] argumentTypes = new Type[] { typeof(string), typeof(string), typeof(RequestValidationSource) }; Type returnType = typeof(void); MethodInfo methodInfo = CommonReflectionUtil.FindMethod(type12, methodName, flag5, argumentTypes, returnType); util._del_validateStringCallback = CommonReflectionUtil.MakeFastCreateDelegate<HttpRequest, ValidateStringCallback>(methodInfo); Type type = CommonAssemblies.SystemWeb.GetType("System.Web.HttpValueCollection"); util._del_HttpValueCollection_ctor = CommonReflectionUtil.MakeFastNewObject<Func<NameValueCollection>>(type); Type type14 = typeof(HttpRequest); string str6 = "_form"; bool flag6 = false; Type type15 = type; FieldInfo info6 = CommonReflectionUtil.FindField(type14, str6, flag6, type15); util._del_get_HttpRequest_form = MakeFieldGetterFunc<HttpRequest, NameValueCollection>(info6); util._del_set_HttpRequest_form = MakeFieldSetterFunc(typeof(HttpRequest), info6); Type type16 = typeof(HttpRequest); string str7 = "_queryString"; bool flag7 = false; Type type17 = type; FieldInfo info7 = CommonReflectionUtil.FindField(type16, str7, flag7, type17); util._del_get_HttpRequest_queryString = MakeFieldGetterFunc<HttpRequest, NameValueCollection>(info7); util._del_set_HttpRequest_queryString = MakeFieldSetterFunc(typeof(HttpRequest), info7); Type type3 = CommonAssemblies.SystemWeb.GetType("System.Web.Util.SimpleBitVector32"); Type type18 = typeof(HttpRequest); string str8 = "_flags"; bool flag8 = false; Type type19 = type3; FieldInfo flagsFieldInfo = CommonReflectionUtil.FindField(type18, str8, flag8, type19); Type type20 = type3; string str9 = "get_Item"; bool flag9 = false; Type[] typeArray4 = new Type[] { typeof(int) }; Type type21 = typeof(bool); MethodInfo itemGetter = CommonReflectionUtil.FindMethod(type20, str9, flag9, typeArray4, type21); Type type22 = type3; string str10 = "set_Item"; bool flag10 = false; Type[] typeArray6 = new Type[] { typeof(int), typeof(bool) }; Type type23 = typeof(void); MethodInfo itemSetter = CommonReflectionUtil.FindMethod(type22, str10, flag10, typeArray6, type23); MakeRequestValidationFlagsAccessors(flagsFieldInfo, itemGetter, itemSetter, out util._del_BitVector32_get_Item, out util._del_BitVector32_set_Item); return util; } catch { return null; } } private static void ReplaceCollection(HttpContext context, FieldAccessor<NameValueCollection> fieldAccessor, Func<NameValueCollection> propertyAccessor, Action<NameValueCollection> storeInUnvalidatedCollection, RequestValidationSource validationSource, ValidationSourceFlag validationSourceFlag) { NameValueCollection originalBackingCollection; ValidateStringCallback validateString; SimpleValidateStringCallback simpleValidateString; Func<NameValueCollection> getActualCollection; Action<NameValueCollection> makeCollectionLazy; HttpRequest request = context.Request; Func<bool> getValidationFlag = delegate { return _reflectionUtil.GetRequestValidationFlag(request, validationSourceFlag); }; Func<bool> func = delegate { return !getValidationFlag(); }; Action<bool> setValidationFlag = delegate (bool value) { _reflectionUtil.SetRequestValidationFlag(request, validationSourceFlag, value); }; if ((fieldAccessor.Value != null) && func()) { storeInUnvalidatedCollection(fieldAccessor.Value); } else { originalBackingCollection = fieldAccessor.Value; validateString = _reflectionUtil.MakeValidateStringCallback(context.Request); simpleValidateString = delegate (string value, string key) { if (((key == null) || !key.StartsWith("__", StringComparison.Ordinal)) && !string.IsNullOrEmpty(value)) { validateString(value, key, validationSource); } }; getActualCollection = delegate { fieldAccessor.Value = originalBackingCollection; bool flag = getValidationFlag(); setValidationFlag(false); NameValueCollection col = propertyAccessor(); setValidationFlag(flag); storeInUnvalidatedCollection(new NameValueCollection(col)); return col; }; makeCollectionLazy = delegate (NameValueCollection col) { simpleValidateString(col[null], null); LazilyValidatingArrayList array = new LazilyValidatingArrayList(_reflectionUtil.GetNameObjectCollectionEntriesArray(col), simpleValidateString); _reflectionUtil.SetNameObjectCollectionEntriesArray(col, array); LazilyValidatingHashtable table = new LazilyValidatingHashtable(_reflectionUtil.GetNameObjectCollectionEntriesTable(col), simpleValidateString); _reflectionUtil.SetNameObjectCollectionEntriesTable(col, table); }; Func<bool> hasValidationFired = func; Action disableValidation = delegate { setValidationFlag(false); }; Func<int> fillInActualFormContents = delegate { NameValueCollection values = getActualCollection(); makeCollectionLazy(values); return values.Count; }; DeferredCountArrayList list = new DeferredCountArrayList(hasValidationFired, disableValidation, fillInActualFormContents); NameValueCollection target = _reflectionUtil.NewHttpValueCollection(); _reflectionUtil.SetNameObjectCollectionEntriesArray(target, list); fieldAccessor.Value = target; } }             Hopefully the above code will help you to understand the internal working of granular request validation. It is also important to note that Microsoft.Web.Infrastructure assembly invokes HttpRequest.ValidateInput method internally. For further understanding please see Microsoft.Web.Infrastructure assembly code. Finally you may ask: at which stage ASP NET MVC 3 will invoke these methods. You will find this answer by looking at the following method source,   Unvalidated extension method for HttpRequest class defined in System.Web.Helpers.Validation class. System.Web.Mvc.MvcHandler.ProcessRequestInit method. System.Web.Mvc.ControllerActionInvoker.ValidateRequest method. System.Web.WebPages.WebPageHttpHandler.ProcessRequestInternal method.       Summary:             ASP.NET helps in preventing XSS attack using a feature called request validation. In this article, I showed you how you can use granular request validation in ASP.NET MVC 3. I explain you the internal working of  granular request validation. Hope you will enjoy this article too.   SyntaxHighlighter.all()

  • Visual WebGui launches a CompanionKit for enhanced developers experience

    - by Webgui
    Visual WebGui launched a new major live demo of the platform's concepts, features and controls and the code behind them. The new Developer CompanionKit is a hige leap forward in the developer experience by allowing developers a hands-on exploration of Visual WebGui which should provide better understanding of the system and the ability to utilize the great advantages of Visual WebGui in order to develop better performing rich web applications. The CompanionKit is available online at companionkit.visualwebgui.com/main.wgx We invite you to Explore Visual WebGui via the new CompanionKit and to watch the CompanionKit Intro video. Below is a screenshot taken from the live CompanionKit which allows developers to see how applying an alternate style to the appearance of a DataGridView is done and how it looks running live and its code (C# or VB.NET). You can access the different Controls (within the Controls section) from the left navigation bar or perform a free text search which shows the relevant results from all the sections - additional sections such as a Concept section are expected to be added in the near future.   In addition, the New Developer CompanionKit which was built with Visual WebGui showcases the enhanced UI design capabilities of building more engaing, modern Web 2.0 applications. The CompanionKit will also be available for download in the next few days as part of the media for 6.4 beta 2 SDK (.NET 2.0 or .NET 3.5) under "Help and Documentation".

  • AJAX Control Toolkit - Globalization (Language)

    - by Guilherme Cardoso
    For those who use AjaxToolKit controls presenting a language-dependent data (the CalendarExternder with the names of the months and weeks, for example) you can change the language to be presented in a simple way. In Web.Config let's define the primary culture as follows: < system . web > <System. Web> < globalization uiCulture = "pt-pt" culture = "pt-pt" /> <Globalization UICulture = "en-us" culture = "en-us" /> ... ...  In this example I'm using Portuguese. To finish it is necessary to change our ScriptManager. Be it the ToolScriptManager AjaxToolKit or belonging to the ScriptManager's framework. NET, the properties as a vibrant and true are the EnableScriptGlobalization EnableScriptLocalization. < cc1 : ToolkitScriptManager ID = "ToolkitScriptManager1" runat = "server" EnableScriptGlobalization = "true" EnableScriptLocalization = "true" > <Cc1: ToolkitScriptManager ID = "ToolkitScriptManager1" runat = "server" EnableScriptGlobalization = "true" EnableScriptLocalization = "true"> </ cc1 : ToolkitScriptManager > </ Cc1: ToolkitScriptManager> or < asp : ScriptManager ID = "ScriptManager1" runat = "server" EnableScriptGlobalization = "true" EnableScriptLocalization = "true" > <Asp: ScriptManager ID = "ScriptManager1" runat = "server" EnableScriptGlobalization = "true" EnableScriptLocalization = "true"> </ asp : ScriptManager > </ Asp: ScriptManager>   Like hus we use the controls on AjaxToolKit, always using the Portuguese language. It is important that AjaxTookKit is updated to avoid shortages or errors in translation, though I have not updated by this error in the ModalPopup the latest version, and any controls that I have used are translated correctly.

  • Dynamic Forms: Pattern or AntiPattern?

    - by Segfault
    I'm sure you've seen it. The database has a bunch of tables called Forms, Controls,FormsControls, ControlSets, Actions and the program that queries these tables has a dynamically generated user interface. It will read all the forms, load a home page that has links to them all, or embed them in some tabbed or paged home page, and for each of those forms it will read the various text boxes, check boxes, radio buttons, submit buttons, combo boxes, labels and whatnot from the controls and form-to-control join tables, lay those elements out according to the database and link all the controls to logic according to other rules in the database. To me, this is an anti-pattern. It actually make the application more difficult to maintain because the design of it is now spread out into multiple different systems. Also, the database is not source controlled. Sure, it may make one or two changes go more quickly, after you've analyzed the program anyway to understand how to change the data and as long as you don't stray from the sort of changes that were anticipated and accounted for, but that's often just not sustainable. What say you?
