• Correct handling of OnMouseWheel events in Ext-GWT

  - by Kevin Loney

  I'm trying to figure out which property of BoxComponentEvent will tell me if the generated OnMouseWheel event was a scroll-up or scroll-down event. I have output the values of all the properties BoxComponentEvent exposes; and all of them (with the exception of the coordinates at which the event took place) stay the same regardless. Google and the…

• Is there an extension or a way to write an extension for firefox that allows a developer to refresh

  - by Kevin J

  I'm a developer, and I spend much of my day refreshing the webapps I work on. Occasionally, I'll encounter pages where POST data was submitted, and firefox will prompt me to Resend POST data or to Cancel. Now, I know that I can just redirect a page to itself to get rid of this warning, but I still want to keep this warning for our users; I…

• XBAPs and MouseWheel events

  - by Kevin Montrose

  I've got an XBAP hosted in FireFox, which works great. However, I cannot detect MouseWheel events ever! I'm guessing that FireFox is consuming them and not passing them down to the hosted app. Any ideas on how to work around this?

• Rails has_and_belongs_to_many relationship question

  - by Kevin Whitaker

  Hello all, I'm sure that this question has been asked somewhere before, as the habtm relationship seems to be very confusing. I have two models, users and promotions. The idea is that a promotion can have many users, and a user can have many promotions. class User < ActiveRecord::Base has_and_belongs_to_many :promotions end class…

• Modal View Controller Undesirably Hides Tab Bar

  - by Kevin Sylvestre

  I am working on an application that requires user authentication to access a profile. The profile section is located solely under one tab (and all others tabs do not require authentication).

• How is Entity Framework 4's POCO support compared to NHibernate?

  - by Kevin Pang

  Just wondering if anyone has had any experience using Entity Framework 4's POCO support and how it stands up compared to NHibernate. If they're the same, I'd be very interested in making Entity Framework 4 my ORM of choice if only because it would: Support both data first AND object first development Have a robust LINQ provider Be…

• ASP MVC Ajax Controller pattern?

  - by Kevin Won

  My MVC app tends to have a lot of ajax calls (via JQuery.get()). It's sort of bugging me that my controller is littered with many tiny methods that get called via ajax. It seems to me to be sort of breaking the MVC pattern a bit--the controller is now being more of a data access component then a URI router. I refactored so that I…

• .NET RegEx "Memory Leak" investigation

  - by Kevin Pullin

  I recently looked into some .NET "memory leaks" (i.e. unexpected, lingering GC rooted objects) in a WinForms app. After loading and then closing a huge report, the memory usage did not drop as expected even after a couple of gen2 collections. Assuming that the reporting control was being kept alive by a stray event handler I…

• How are RESTful WCF services secured so that only the calling application can call them?

  - by Kevin Babcock

  I have an application that uses Silverlight and ASP.NET as a front-end. It retrieves data from the server by calling some RESTful WCF services that are hosted there. I'd like to prevent the curious user from opening up a new browser window and calling the web service themselves. Is there a way to restrict access to the web…

• CSS Background-Images Loading after HTML Images (Involves Javascript)

  - by Kevin C.

  I threw together a quick little microsite that you can see at http://monterraauction.com. If you don't have a super-fast connection (and nothing's cached), the very last items to load are the background-images that are used for CSS image-text replacement (primarily, that h1#head at the top, with a 7kb background image).…

• How do I call window.openDatabase from a webView hosted in an android application?

  - by Kevin

  I created a native Android app that basically hosts a webView control. That webView is then used to load a page that calls window.openDatabase from JavaScript. I can successfully confirm that the API exists by verifying window.openDatabase. Calling this method returns a null when called in a hosted webView control. …

• Can I draw Qt objects directly to Win32 DC (Device Context)?

  - by Kevin

  I can draw Qt objects to an QImage and then draw the image to HDC or CDC. This may hurt our application's performance. It would be great if I can draw Qt objects directly to Win32 HDC or MFC CDC. I expect that there is a class, say QWin32Image for clear, then I can use it in this way: QWin32Image image(hdc, 100,…

  At work we have laptops with encrypted harddrives. Most developers here (on occasion I have been guilty of it too) leave their laptops in hibernate mode when they take them home at night. Obviously, Windows (i.e. there is a program running in the background which does it for windows) must have a method to…
