  • Set a dropdown option to selected based on get variable in url in Razor MVC

    - by Mason240
    I have a dropdown menu in a GET form. When the user hits submit, they are directed to the same page and shown the form again. I would like to have the dropdown option the user displayed in the last page already selected. So for example: @Html.DropDownList("Type", null, "Type", new { @class = "sbox-input" } ) website.com/Search?Type="Beef" <select name="Type"> <option value="Fish" >Fish</option> <option value="Chicken" >Chicken</option> <option value="Beef" selected="selected">Beef</option> </select> A jQuery solution would work just as well.

  • How do you get XML::Pastor to set xsi:type for programmatically generated elements?

    - by Derrick
    I'm learning how to use Perl as an automation test framework tool for a Java web service and running into trouble generating xml requests from the Pastor generated modules. The problem is that when including a type that extends from the required type for an element, the xsi:type is not included in the generated xml string. Say, for example, I want to generate the following xml request from the modules that XML::Pastor generated from my xsd: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <PromptAnswersRequest xmlns="http://mycompany.com/api"> <Uri>/some/url</Uri> <User ref="1"/> <PromptAnswers> <PromptAnswer xsi:type="textPromptAnswer" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <Prompt ref="2"/> <Children> <PromptAnswer xsi:type="choicePromptAnswer"> <Prompt ref="1"/> <Choice ref="2"/> </PromptAnswer> </Children> <Value>totally</Value> </PromptAnswer> </PromptAnswers> </PromptAnswersRequest> What I'm getting currently is this: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <PromptAnswersRequest xmlns="http://mycompany.com/api"> <Uri>/some/url</Uri> <User ref="1"/> <PromptAnswers> <PromptAnswer> <Prompt ref="2"/> <Children> <PromptAnswer> <Prompt ref="1"/> <Choice ref="2"/> </PromptAnswer> </Children> <Value>totally</Value> </PromptAnswer> </PromptAnswers> </PromptAnswersRequest> Here are some relavent snippets from the xsd: <xs:complexType name="request"> <xs:sequence> <xs:element name="Uri" type="xs:anyURI"/> </xs:sequence> </xs:complexType> <xs:complexType name="promptAnswersRequest"> <xs:complexContent> <xs:extension base="api:request"> <xs:sequence> <xs:element name="User" type="api:ref"/> <xs:element name="PromptAnswers" type="api:promptAnswerList"/> </xs:sequence> </xs:extension> </xs:complexContent> </xs:complexType> <xs:complexType name="promptAnswerList"> <xs:sequence> <xs:element name="PromptAnswer" type="api:promptAnswer" minOccurs="0" maxOccurs="unbounded"/> </xs:sequence> </xs:complexType> <xs:complexType name="promptAnswer" abstract="true"> <xs:sequence> <xs:element name="Prompt" type="api:ref"/> <xs:element name="Children" type="api:promptAnswerList" minOccurs="0"/> </xs:sequence> </xs:complexType> <xs:complexType name="textPromptAnswer"> <xs:complexContent> <xs:extension base="promptAnswer"> <xs:sequence> <xs:element name="Value" type="api:nonEmptyString" minOccurs="0"/> </xs:sequence> </xs:extension> </xs:complexContent> </xs:complexType> And here are relavent parts of the script: my $promptAnswerList = new My::API::Type::promptAnswerList; my @promptAnswers; my $promptAnswerList2 = new My::API::Type::promptAnswerList; my @textPromptAnswerChildren; my $textPromptAnswer = new My::API::Type::textPromptAnswer; my $textPromptAnswerRef = new My::API::Type::ref; $textPromptAnswerRef->ref('2'); $textPromptAnswer->Prompt($textPromptAnswerRef); my $choicePromptAnswer = new My::API::Type::choicePromptAnswer; my $choicePromptAnswerPromptRef = new My::API::Type::ref; my $choicePromptAnswerChoiceRef = new My::API::Type::ref; $choicePromptAnswerPromptRef->ref('1'); $choicePromptAnswerChoiceRef->ref('2'); $choicePromptAnswer->Prompt($choicePromptAnswerPromptRef); $choicePromptAnswer->Choice($choicePromptAnswerChoiceRef); push(@textPromptAnswerChildren, $choicePromptAnswer); $promptAnswerList2->PromptAnswer(@textPromptAnswerChildren); $textPromptAnswer->Children($promptAnswerList2); $textPromptAnswer->Value('totally'); push(@promptAnswers, $pulseTextPromptAnswer); push(@promptAnswers, $textPromptAnswer); I haven't seen this addressed anywhere in the documentation for the XML::Pastor modules, so if anyone can point me at a good reference for its use it would be greatly appreciated. Also, I'm only using XML::Pastor because I don't know of any other modules that can do this, so if any of you know of something either easier to use, or more well maintained, please let me know about that too!

  • Using JavaScript eval to parse JSON

    - by Quandary
    Question: I'm using eval to parse a JSON return value from one of my WebMethods. I prefer not to add jquery-json because the transfer volume is already quite large. So I parse the JSON return value with eval. Now rumors go that this is insecure. Why ? Nobody can modify the JSOn return value unless they hack my server, in which case I would have a much larger problem anyway. And if they do it locally, JavaScript only executes in their browser. So I fail to see where the problem is. Can anybody shed some light on this, using this concrete example? function OnWebMethodSucceeded(JSONstrWebMethodReturnValue) { var result=eval('(' + JSONstrWebMethodReturnValue + ')') ... // Adding result.xy to a table }

  • Formatting a string in Java using class attributes

    - by Jason R. Coombs
    I have a class with an attribute and getter method: public Class MyClass { private String myValue = "foo"; public String getMyValue(); } I would like to be able to use the value of foo in a formatted string as such: String someString = "Your value is {myValue}." String result = Formatter.format(someString, new MyClass()); // result is now "Your value is foo." That is, I would like to have some function like .format above which takes a format string specifying properties on some object, and an instance with those properties, and formats the string accordingly. Is it possible to do accomplish this feat in Java?

  • MVVM (ICommand) in Silverlight

    - by Andrey Khataev
    Hello! Please, don't judge strictly if this question was discussed previously or indirectly answered in huge nearby prism and mvvm blogs. In WPF implementation of RelayCommand or DelegateCommand classes there is a such eventhandler /// <summary> /// Occurs whenever the state of the application changes such that the result of a call to <see cref="CanExecute"/> may return a different value. /// </summary> public event EventHandler CanExecuteChanged { add { CommandManager.RequerySuggested += value; } remove { CommandManager.RequerySuggested -= value; } } but in SL subset of namespaces there are no CommandManager class. And this is where I'm stuck. I haven't yet found an workaround for this in MVVM adoptation for SL (PRISM is so complex for me yet). Different simple HelloWorldMVVM apps don't deal with at all. Thanks in advance and sorry for my English -)

    Is there an easy way to apply the trend line formula from a chart to any given X value in Excel? For example, I want to get the Y value for a given X = $2,006.00. I've already taken the formula and retyped it out be: =-0.000000000008*X^3 - 0.00000001*X^2 + 0.0003*X - 0.0029 I am continually making adjustments to the trend line by adding more data, and don't want to retype out the formula every time.

  • 0xDEADBEEF equivalent for 64-bit development?

    - by Peter Mortensen
    For C++ development for 32-bit systems (be it Linux, Mac OS or Windows, PowerPC or x86) I have initialised pointers that would otherwise be undefined (e.g. they can not immediately get a proper value) like so: int *pInt = reinterpret_cast<int *>(0xDEADBEEF); (To save typing and being DRY the right-hand side would normally be in a constant, e.g. BAD_PTR.) If pInt is dereferenced before it gets a proper value then it will crash immediately on most systems (instead of crashing much later when some memory is overwritten or going into a very long loop). Of course the behavior is dependent on the underlying hardware (getting a 4 byte integer from the odd address 0xDEADBEEF from a user process may be perfectly valid), but the crashing has been 100% reliable for all the systems I have developed for so far (Mac OS 68xxx, Mac OS PowerPC, Linux Redhat Pentium, Windows GUI Pentium, Windows console Pentium). For instance on PowerPC it is illegal (bus fault) to fetch a 4 byte integer from an odd address. What is a good value for this on 64-bit systems?

  • Modify Emdeded String in C# compiled exe

    - by nitefrog
    I have an issue where I need to be able to have a compiled exe ( .net 3.5 c# ) that I will make copies of to distribute that will need to change a key for example before the exe is sent out. I cannot compile each time a new exe is needed. This is a thin client that will be used as part of a registration process. Is it possible to add a entry to a resource file with a blank value then when a request comes in have another application grab the blank default thin client, copy it, populate the blank value with the data needed. If yes how? If no do you have any ideas? I have been scratching my head for a few days now and the limitation as due to the boundaries I am required to work in. The other idea I has was to inject the value into a method, which I have no idea how I would even attempt that. Thanks.

  • Where are events in Cocoa Touch?

    - by yesenin
    Hi all! I learn Cocoa Touch several days, and today have stuck while looking for way to implement a custom event. Event that I can see in Connection Inspector for my UIView subclass. What I have: There are a UILabel and MyView:UIView on MainVindow. MyView contains a UISlider. Interfaces for Controller and MyView // Controller.h @interface Controller : NSObject { IBOutlet UILabel *label; IBOutlet MyView *myView; } // I suppose that there should be something like -(IBAction) changeLabelValue for myView event @end // MyView.h @interface MyView : UIView { IBOutlet UISlider *slider; float value; } - (IBAction) changeValue; //for slider "Changed Value" event What I want: Add something in MyView that allows it to rise a event after change value. Can anybody help me? My main area in programming is .NET and I begin think that its terminology is not appropriate for this case. Thanks.

  • jQuery .val Enigma between two input boxes

    - by Matt
    I'm trying to get it so that if I move a red div-square around the screen using jQuery UI and jQuery, then an input field updates with the position of the div. I got that working with a simple .val. But, it's hard to explain why, but I need to make it so that when I move the square, it updates my input box, and when the input box value is changed, another input box reflects the new value of the old input box. Do I make any sense, coz I'm confusing myself :). I made a jsfiddle, so perhaps it'll make more sense there. If you move the red square, then the input box directly above it updates, but the input box above that does not, even though it is programmed to reflect the value of the input box below itself. P.S. Is this specific to only jQuery, or is this problem present in all of JavaScript. Thanks! http://jsfiddle.net/xmCsq/27/

  • Issue on passing a checkbox set to an AppEngine script through jQuery Ajax/Json

    - by Jorge
    I have a set of checkboxes with multiple choice allowed. I parse the set this way: if ($("input[name='route_day']:checked").length > 0) { $("input[name='route_day']:checked").each(function(){ if(this.value != null) route_days_hook.push(this.value); }); dataTrap.route_days = $.JSON.encode(route_days_hook); } ...and pull the whole dataTrap to an AppEngine Python script via jQuery ajax. However, the Python script just bugs. If i change dataTrap.route_days value to a string instead of the JSON encoded object, everything works fine. My question is: how can i pass a checkbox set to the script using Ajax and still be able to iterate over it on the script?

  • DataBinding and ErrorProvider - How to provide custom error messages?

    - by BeowulfOF
    We use BusinessObjects, implementing IDataErrorInfo and IEditableObject. BindingLists with those Objects are added to BindingSources, those are used to bind UserControls and DataGrids on the forms (WinForms). The BindingSource is additionally set as DataSource to the ErrorProvider of the form. We do use currently TextBoxes for Properties of Type int and short. They are validated inside the BusinessObjects with custom validation, like min/max values, etc. That works fine, since error message form our custom validations show up nicely next to the TextBox. However, if the input is greater than the value of an int (e.g. "9999999999") the BindingSource doesn't even try to enter that Value into the BusinesObject but instead gives the errormessage to the errorprovider like "The value for Int32 was too big.". We do not want to bother our users with "Int32" but want a custom errormessage for that. It is nice, that the BindingSource does provide this feature, but is it possible to provide custom error messages for this?

  • How to write a Custom DesignerSerializer for an class used by a Activity (WF)

    - by Stefan Steinegger
    I have a type which is used in a WF activity. It should be serialized. It doesn't work out of the box, most probably because of the private setters in that type. I'm not sure if this is the correct way, but I tried to write my own serializer and declared it on my class. [DesignerSerializer( typeof(FooDesignerSerializer), // my custom serializer typeof(WorkflowMarkupSerializer))] public class Foo { public Foo(int value, string name { // ... } public int Value { get; private set; } public string Name { get; private set; } } Is this the easiest way to get it serialized? How do I write this serializer? That's what I got so far: public class FooDesignerSerializer : WorkflowMarkupSerializer { protected override string SerializeToString( WorkflowMarkupSerializationManager serializationManager, object value) { // how to create a valid / XOML-like string? } }

  • CRM plugin to execute when opportunity is reopened

    - by splatto
    I need to write a plugin for Dynamics CRM 4.0 that executes when a closed opportunity is reopened in order to change the salesstagecode. My questions are: When I register a new step to the plugin, what attribute(s) should I filter on? What property on the entity should I check the value of? and What should I look for the value of this entity to be so I can determine if the plugin execution should continue? I've typically written asynchronous workflows and my experience writing plugins is still developing, so I'd appreciate any help and clarification that can be offered. Please see below the plugin skeleton I've written public void Execute(IPluginExecutionContext context) { if (context.InputParameters.Properties.Contains("Target") && context.InputParameters.Properties["Target"] is DynamicEntity) { ICrmService service = context.CreateCrmService(false); DynamicEntity entity = (DynamicEntity)context.InputParameters.Properties["Target"]; if (entity.Name == EntityName.opportunity.ToString()) { if (entity.Properties.Contains(/*What Property Should I Check Here?*/)) { //And what value should I be looking for in that property? } } } }

  • Why an input button created dynamically through a literal tag doesn't work ?

    - by user284523
    I have created button 2 below: <input id="Button1" type="button" value="Stop" onclick="alert('hello world');"/> <input id="Button2" type="button" value="button" OnClik="alert('hello world');"/> using a litteral tag on page load like this: protected void Page_Load(object sender, EventArgs e) { Literal1.Text = "<input id=\"Button2\" type=\"button\" value=\"button\" OnClik=\"alert('hello world');\"/>"; } Incredibly when testing in browser, click on button 1 works, not click on button 2 whereas the codes are the same ! Am I missing something ?

  • TemplateBinding and additional string in Silverlight

    - by aaginor
    Hi folks, In my Silverlight 3 application, I created a custom Tooltip, that is shown when the mouse is over a part of a Pie-Chart. The displayed values are set via TemplateBinding: <ToolTipService.ToolTip> <StackPanel> <ContentControl Content="{TemplateBinding IndependentValue}" FontWeight="Bold" /> <ContentControl Content="{TemplateBinding FormattedDependentValue}"/> <ContentControl Content="{TemplateBinding FormattedRatio}"/> </StackPanel> </ToolTipService.ToolTip> The tooltip shows the title of the pie-slice, the value that the size of the slice is based on and the percentage regarding the whole pie: MyTitel 9 12% Now, I want to add a constant string to the value, to show the following: MyTitel 9 items 12% the string 'items' shall be added to the displayed number. Is there a way to add the constant string to the Content-Property of the ContentControl? (I have no influence on the binded value FormattedDependentValue) Thanks in advance, Frank

  • GIMP: Slightly wrong color when saving images

    - by chris_l
    When I create a new image, fill it with a single color, and save it as *.png or *.jpeg, it gets a slightly wrong color. When I save it as *.gif, the color is correct. Does this have something to do with a color profile? How can I turn it off? (Gimp 2.6.7 on Mac) BTW, when I use "Digital Color Meter" to check the color in the GIMP window, I also get a wrong value - but that value is again a little bit different.

  • How do I make a simple image-based button with visual states in Silverlight 3?

    - by Jacob
    At my previous company, we created our RIAs using Flex with graphical assets created in Flash. In Flash, you could simply lay out your graphics for different states, i.e. rollover, disabled. Now, I'm working on a Silverlight 3 project. I've been given a bunch of images that need to serve as the graphics for buttons that have a rollover, pressed, and normal state. I cannot figure out how to simply create buttons with different images for different visual states in Visual Studio 2008 or Expression Blend 3. Here's where I am currently. My button is defined like this in the XAML: <Button Style="{StaticResource MyButton}"/> The MyButton style appears as follows: <Style x:Key="MyButton" TargetType="Button"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="Button"> <Image Source="/Assets/Graphics/mybtn_up.png" Width="54" Height="24"> <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="FocusStates"> <VisualState x:Name="Focused"/> <VisualState x:Name="Unfocused"/> </VisualStateGroup> <VisualStateGroup x:Name="CommonStates"> <VisualState x:Name="Normal"/> <VisualState x:Name="MouseOver"/> <VisualState x:Name="Pressed"/> <VisualState x:Name="Disabled"/> </VisualStateGroup> </VisualStateManager.VisualStateGroups> </Image> </ControlTemplate> </Setter.Value> </Setter> </Style> I cannot figure out how to assign a different template to different states, nor how to change the image's source based on which state I'm in. How do I do this? Also, if you know of any good documentation that describes how styles work in Silverlight, that would be great. All of the search results I can come up with are frustratingly unhelpful. Edit: I found a way to change the image via storyboards like this: <Style x:Key="MyButton" TargetType="Button"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="Button"> <Image Source="/Assets/Graphics/mybtn_up.png" Width="54" Height="24" x:Name="Image"> <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="FocusStates"> <VisualState x:Name="Focused"/> <VisualState x:Name="Unfocused"/> </VisualStateGroup> <VisualStateGroup x:Name="CommonStates"> <VisualState x:Name="Normal"/> <VisualState x:Name="MouseOver"> <Storyboard Storyboard.TargetName="Image" Storyboard.TargetProperty="Source"> <ObjectAnimationUsingKeyFrames> <DiscreteObjectKeyFrame KeyTime="0" Value="/Assets/Graphics/mybtn_over.png"/> </ObjectAnimationUsingKeyFrames> </Storyboard> </VisualState> <VisualState x:Name="Pressed"> <Storyboard Storyboard.TargetName="Image" Storyboard.TargetProperty="Source"> <ObjectAnimationUsingKeyFrames> <DiscreteObjectKeyFrame KeyTime="0" Value="/Assets/Graphics/mybtn_active.png"/> </ObjectAnimationUsingKeyFrames> </Storyboard> </VisualState> <VisualState x:Name="Disabled"/> </VisualStateGroup> </VisualStateManager.VisualStateGroups> </Image> </ControlTemplate> </Setter.Value> </Setter> </Style> However, this seems like a strange way of doing things to me. Is there a more standard way of accomplishing this?

  • Boolean issues in PHP

    - by McNabbToSkins
    I have a question regarding bools in php. I have a stored mysql proc that is returning a boolean. When this value is grabbed on the php side it displays the value as being a 0 or 1. This all seems fine to me and I have read in the php manual that php will interpret a 0 or 1 as false or true at compile time but this does not seem to be the case to me. I have gone a step further and casted my returned value with (bool) but this still does not seem to work. My if statements are not properly firing because of this. Does anyone know what is going on? Thanks for the help.

  • SqlParameter contructor compiler overload choice

    - by Ash
    When creating a SqlParameter (.NET3.5) or OdbcParameter I often use the SqlParameter(string parameterName, Object value) constructor overload to set the value in one statement. When I tried passing a literal 0 as the value paramter I was initially caught by the C# compiler choosing the (string, OdbcType) overload instead of (string, Object). MSDN actually warns about this gotcha in the remarks section, but the explanation confuses me. Why does the C# compiler decide that a literal 0 parameter should be converted to OdbcType rather than Object? The warning also says to use Convert.ToInt32(0) to force the Object overload to be used. It confusingly says that this converts the 0 to an "Object type". But isn't 0 already an "Object type"? The Types of Literal Values section of this page seems to say literals are always typed and so inherit from System.Object. This behavior doesn't seem very intuitive given my current understanding? Is this something to do with Contra-variance or Co-variance maybe?

  • How can I have a serializable struct that wraps it's self as an int32 implicitly? in C#?

    - by firoso
    Long story short, I have a struct (see below) that contains exactly one field: private int value; I've also implemented implicit conversion operators: public static implicit operator int(Outlet val) { return val.value; } public static implicit operator Outlet(int val) { return new Outlet(val); } I've implemented all of the following : IComparable, IComparable<Cart>, IComparable<int>, IConvertible, IEquatable<Cart>, IEquatable<int>, IFormattable I'm at a point where I really have no clue why, but whenever I serialize this object, I get no value. For instance, with XmlSerialization: <Outlet /> Also, I'm not solely concerned about XmlSerialization, I'm concerned about ALL serialization (binary for instance) How can I ensure that this serializes properly? NOTE: I did this because mapping an int,int dictionary seemed rather poorly typed to me when explicit objects with validation behavior were desired.
