• Regular expression not working after debugging

  - by Jaison

  I have an ASP.NET website with a regular expression validator text box. I have changed the expression in the regular expression validation property "validator expression" and after compiling (rebuild) and running, the validation CHANGEs are not reflecting. The previous validation is working fine but the changed validation is not working. Please help me! edit: First code: ([a-zA-Z0-9_-.]+)\@((base.co.uk)|(base.com)|(group.com)) Second code: @"([a-zA-Z0-9_\-.]+)@((base\.co\.uk)|(base\.com)|(group\.com)|(arg\.co\.uk)|(arggroup\.com))"

• Subclass not seeing superclass' instance variable

  - by hyn

  I have a situation where my subclass is not seeing the superclass' instance variable x. The ivar is obviously @protected by default, so why do I get a compiler error "x undeclared"? If I make this ivar a property then I can access it by self.x. What's worse is sometimes the error disappears, so something in my code is obviously causing this error but I cannot figure it out.

• WebBrowser control not navigating to links to "file://" protocol URIs

  - by Nick Butler

  I am setting the DocumentText property to an HTML string that contains links like: <a href="file:///D:/dir/file.html">NewPage</a> The links are shown properly in the WebBrowser, but nothing happens when I click them. The Navigating, Navigated and DocumentComplete events do not fire - nothing seems to happen at all. AllowNavigation is true and other links using HTTP are working. Any ideas please? Nick

  - by Nathan Campos

• How to redisplay a page in iPhone UIWebView

  - by Monty

  I've got a UIWebView which starts off with the scalesPagesToFit property set to YES. This loads up the page and scales it fine. When the user taps a button I want to turn off the scaling and show the page full size but I'm struggling to figure out how to force the page to redraw. I specifically do not want to refresh the page (ie fetch it from the server again) just redraw the page that has already been downloaded. I've tried setNeedsLayout and setNeedsDisplay but neither of these work

• Enterprise Library Validation Block - Validate nullable properties?

  - by Robert MacLean

  I am trying to come up with a validation for a nullable property, like int? Example [RangeValidator(0, RangeBoundaryType.Inclusive, 1, RangeBoundaryType.Inclusive)] int? Age { get; set; } However if I set Age to null validation fails because it doesn't fall in the range, I know I need an [ValidatorComposition(CompositionType.Or)] as well, but what else should I use?

  I'm seeing a System.Diagnositics.Process.HasExited method throw an InvalidOperationException but the message text property is not terribly useful as to why it was thrown. Under what conditions does this exception get thrown?

• How to access static members in a Velocity template?

  - by matt b

  I'm not sure if there is a way to do this in Velocity or not: I have a User POJO which a property named Status, which looks like an enum (but it is not, since I am stuck on Java 1.4), the definition looks something like this: public class User { // default status to User private Status status = Status.USER; public void setStatus(Status status) { this.status = status; } public Status getStatus() { return status; } And Status is a static inner class: public static final class Status { private String statusString; private Status(String statusString) { this.statusString = statusString; } public final static Status USER = new Status("user"); public final static Status ADMIN = new Status("admin"); public final static Status STATUS_X = new Status("blah"); //.equals() and .hashCode() implemented as well } With this pattern, a user status can easily be tested in a conditional such as if(User.Status.ADMIN.equals(user.getStatus())) ... ... without having to reference any constants for the status ID, any magic numbers, etc. However, I can't figure out how to test these conditionals in my Velocity template with VTL. I'd like to just print a simple string based upon the user's status, such as: Welcome <b>${user.name}</b>! <br/> <br/> #if($user.status == com.company.blah.User.Status.USER) You are a regular user #elseif($user.status == com.company.blah.User.Status.ADMIN) You are an administrator #etc... #end But this throws an Exception that looks like org.apache.velocity.exception.ParseErrorException: Encountered "User" at webpages/include/dashboard.inc[line 10, column 21] Was expecting one of: "[" ... From the VTL User Guide, there is no mention of accessing a Java class/static member directly in VTL, it appears that the right hand side (RHS) of a conditional can only be a number literal, string literal, property reference, or method reference. So is there any way that I can access static Java properties/references in a Velocity template? I'm aware that as a workaround, I could embed the status ID or some other identifier as a reference in my controller (this is a web MVC application using Velocity as the View technology), but I strongly do not want to embed any magic numbers or constants in the view layer.

• Combobox item style

  - by user373721

  my project is asp.net MVC, using Telerik MVC combobox. I can change the sytle of the first item if I use: var item = combobox.dropDown.$items.first(); item.addClass('test'); Or change all items, using: combobox.dropDown.$items.addClass('test'); But I need to change just specific items (based on a model), I tried: combobox.dropDown.$items[1].addClass('test'); I get this error: Object doesn't support property or method 'addClass'

• "freeze" one column in flex datagrid

  - by Bob Spidell

  I'm using a datagrid to display a column of date ranges and several columns of data. I'd like to make the first column (the date ranges) fixed; i.e. that column stays in place when the user scrolls the other columns. That way, the dates column will always be visible as the user scrolls through many data columns. I don't see a datagrid property for this; anyone have a solution? TIA

• How do I refactor these two C# functions to abstract their logic from the specific class properties

  - by ObligatoryMoniker

  I have two functions whose underlying logic is the same but in one case it sets one property value on a class and in another case it sets a different one. How can I rewrite the following two functions to abstract away as much of the algorithm as possible so that I can make changes in logic in a single place? SetBillingAddress private void SetBillingAddress(OrderAddress newBillingAddress) { BasketHelper basketHelper = new BasketHelper(SiteConstants.BasketName); OrderAddress oldBillingAddress = basketHelper.Basket.Addresses[basketHelper.BillingAddressID]; bool NewBillingAddressIsNotOldBillingAddress = ((oldBillingAddress == null) || (newBillingAddress.OrderAddressId != oldBillingAddress.OrderAddressId)); bool BillingAddressHasBeenPreviouslySet = (oldBillingAddress != null); bool BillingAddressIsNotSameAsShippingAddress = (basketHelper.ShippingAddressID != basketHelper.BillingAddressID); bool NewBillingAddressIsNotShippingAddress = (newBillingAddress.OrderAddressId != basketHelper.ShippingAddressID); if (NewBillingAddressIsNotOldBillingAddress && BillingAddressHasBeenPreviouslySet && BillingAddressIsNotSameAsShippingAddress) { basketHelper.Basket.Addresses.Remove(oldBillingAddress); } if (NewBillingAddressIsNotOldBillingAddress && NewBillingAddressIsNotShippingAddress) { basketHelper.Basket.Addresses.Add(newBillingAddress); } basketHelper.BillingAddressID = newBillingAddress.OrderAddressId; basketHelper.Basket.Save(); } And here is the second one: SetShippingAddress private void SetBillingAddress(OrderAddress newShippingAddress) { BasketHelper basketHelper = new BasketHelper(SiteConstants.BasketName); OrderAddress oldShippingAddress = basketHelper.Basket.Addresses[basketHelper.ShippingAddressID]; bool NewShippingAddressIsNotOldShippingAddress = ((oldShippingAddress == null) || (newShippingAddress.OrderAddressId != oldShippingAddress.OrderAddressId)); bool ShippingAddressHasBeenPreviouslySet = (oldShippingAddress != null); bool ShippingAddressIsNotSameAsBillingAddress = (basketHelper.ShippingAddressID != basketHelper.BillingAddressID); bool NewShippingAddressIsNotBillingAddress = (newShippingAddress.OrderAddressId != basketHelper.BillingAddressID); if (NewShippingAddressIsNotOldShippingAddress && ShippingAddressHasBeenPreviouslySet && ShippingAddressIsNotSameAsBillingAddress) { basketHelper.Basket.Addresses.Remove(oldShippingAddress); } if (NewShippingAddressIsNotOldShippingAddress && NewShippingAddressIsNotBillingAddress) { basketHelper.Basket.Addresses.Add(newShippingAddress); } basketHelper.ShippingAddressID = newShippingAddress.OrderAddressId; basketHelper.Basket.Save(); } My initial thought was that if I could pass a class's property by refernce then I could rewrite the previous functions into something like private void SetPurchaseOrderAddress(OrderAddress newAddress, ref String CurrentChangingAddressIDProperty) and then call this function and pass in either basketHelper.BillingAddressID or basketHelper.ShippingAddressID as CurrentChangingAddressIDProperty but since I can't pass C# properties by reference I am not sure what to do with this code to be able to reuse the logic in both places. Thanks for any insight you can give me.

• TeamCity build number versus Ant build number task

  - by jonny

  I have a build project that I run from TeamCity, now it takes the build.number from TeamCity. I want to be able to use the buildnumber task (Ant) which in my understanding when used, is supposed to change the value of build number property and increment it for next time. But it seems that I still get the build number from TeamCity. How can I use the build number from <buildnumber file="mybuild.number"/>?

• Can I make Visual Studio's code completion window more like Eclipse (Java)?

  - by Matt

  Is it possible to make Visual Studio 2010's code completion window more like that of Eclipse (Java)? In particular, I'd love the code completion window to give me a variable's type, and a method's return type and expected parameters, without needing to hover the highlight over that particular variable/method. VS's code completion's little icons that indicate if something is a property, method etc are useful, but they just aren't enough.
