  • WPF XAML Bind Grid

    - by Jon Archway
    I have a custom user control that is based on a Grid control. I have a ViewModel that exposes this as a property. I would like the XAML on the view to bind to this. I am sure this must be easy but I am quite new to WPF. How is this achieved? Many thanks in advance

  • What do you call a set of Javascript closures that share a common context?

    - by Ed Stauff
    I've been trying to learn closures (in Javascript), which kind of hurts my brain after way too many years with C# and C++. I think I now have a basic understanding, but one thing bothers me: I've visited lots of websites in this Quest for Knowledge, and nowhere have I seen a word (or even a simple two-word phrase) that means "a set of Javascript closures that share a common execution context". For example: function CreateThingy (name, initialValue) { var myName = name; var myValue = initialValue; var retObj = new Object; retObj.getName = function() { return myName; } retObj.getValue = function() { return myValue; } retObj.setValue = function(newValue) { myValue = newValue; } return retObj; }; From what I've read, this seems to be one common way of implementing data hiding. The value returned by CreateThingy is, of course, an object, but what would you call the set of functions which are properties of that object? Each one is a closure, but I'd like a name I can used to describe (and think about) all of them together as one conceptual entity, and I'd rather use a commonly accepted name than make one up. Thanks! -- Ed

  • How can I make the Entity data model designer use my database column descriptions?

    - by Jack
    I am using EF4 with Visual Studio 2010. I have a SQL database already created and all my columns are documented with the Description property in SQL management studio. When I create the edmx in Visual Studio, how can I make it read those descriptions and use them to add comments to my generated classes? I know I can use the Summary and LongDescription in the edmx properties but I'm looking for a way to do this without having to copy and paste every description. Thanks!

  • Class definition thinks setting a variable is a Unit?

    - by DeLongey
    Writing out a Scala class and problem here is that the compiler thinks that the code is a unit not returning the proper value. It's a method used to set a property in the class: def setObject(`object`:StripeObject):StripeObject = { this.`object` = `object` } The error is: type mismatch; found : Unit required: com.stripe.StripeObject The full class is: case class EventData(var previousAttributes: HashMap[String,Object], var `object`:StripeObject) extends StripeObject { def getPreviousAttributes = { previousAttributes } def setPreviousAttributes(previousAttributes: HashMap[String, Object]) = { this.previousAttributes = previousAttributes } def getObject = { `object` } def setObject(`object`:StripeObject):StripeObject = { this.`object` = `object` } } How do I make sure it doesn't return a Unit?

  • Show div based on getDay and getHours + getMinutes

    - by Peta Reardon
    I am building a website for a radio station and want to show which presenter is currently on air. I have built a web app that contains data on the presenter: name, photo, bio and start/end times for each weekday. <div id="presenter1"> <div class="slot"> <div id="sunday-off"> - </div> <div id="monday-afternoon">12:00 - 15:59</div> <div id="tuesday-afternoon">12:00 - 15:59</div> <div id="wednesday-afternoon">12:00 - 15:59</div> <div id="thursday-afternoon">12:00 - 15:59</div> <div id="friday-afternoon">12:00 - 15:59</div> <div id="saturday-morning">06:00 - 08:59</div> </div> </div> What I would like to do is use Javascript functions getDay() and getHours() + getMinutes() to show only the presenter that is scheduled to be on air based on the times specified in the app. The main part I am having difficulty with is with determining whether this presenter falls within the current time and then showing/hiding the div as necessary. Any help or guidance on how I can acheive this would be greatly appreciated.

  • STL container to pop() by priority?

    - by Pirate for Profit
    I'm writing a thread-pool for Qt as QRunnable doesn't handle event loops in new threads. Not too familiar with STL, what would be the best way to pop() something by priority? Priority should probably be a property of MyRunnable imo, but I can always give that info to an STL container when adding the runnable to the queue.

  • CSS Doozie: Replacing BG Image on SELECT dropdown

    - by ToiletOverflow
    I need to be able to change the background-image property of a SELECT drop-down using JavaScript/CSS. We have been able to accomplish this in Firefox, but it doesn't appear to be supported at all in IE. From what I've read, IE won't support this. But I'm wondering if there's anything else I could try. Does anyone here have any recommendations?

  • Wordpress Contact Form 7 in a hidden div.

    - by Luke
    Hi there, I'm using Contact Form 7 on Wordpress. I have it set up so the upload appears in the 3rd of three divs that hide and show depending on a clicked link. Everything is fine except when I click submit it hides the uploads div and shows the first div again. The form is submitting fine and you see a message that it has sent if you navigate back to the uploads section. Is there any way to keep the div you're in open and keep the rest hidden on submit? This is the code i'm using for hiding and showing. I'm sure it's not perfect but it works. // My Files function basic_myfiles($atts, $content = null) { return '' . $content . ''; } add_shortcode("myfiles", "basic_myfiles"); // Sound Library function basic_soundlib($atts, $content = null) { return '' . $content . ''; } add_shortcode("soundlib", "basic_soundlib"); // Uploads function basic_uploads($atts, $content = null) { return '' . $content . do_shortcode( '[contact-form 4 "Client Upload Form"]' ) . ''; } add_shortcode("uploads", "basic_uploads"); Thanks
