WPF easy rounded corners for anything

Fri, 03 Oct 2008 16:29:50 GMT

WPF's Border element allows you to specify a different radius for each corner. Unfortunately it doesn't clip content to fit inside the boundary. While there are other solutions, this one is my favorite so far... :)

Silverlayout - Simple Actionscript layout library

Here's a simple library that gives you Silverlight / WPF -like layout controls in Actionscript 3.

YouCube 2.0 - Interactive!

Tue, 16 Sep 2008 06:04:56 GMT

My YouCube demo is now interactive! :) Based on code and ideas from Jeremiah Morrill's excellent Win32Renderer - the main difference is this demo only refreshes the page when something changes, rather than regularly updating with a timer. To obtain the actual page snapshot, IViewObject.Draw is used. The image is copied to a WriteableBitmap and rendered as a Viewport2DVisual3D (both new in .NET 3.5).

Demos - ClickOnce deployment

Here are ClickOnce deployments for some WPF demos and apps I've done...

YouCube (3D WPF web browser)

Thu, 04 Sep 2008 07:46:59 GMT

As you know, .NET 3.5 SP1 includes a WebBrowser control. The current implementation is just a wrapper around the MSHTML ActiveX control, which unfortunately prevents you from doing crazy things to it through WPF. The ActiveX control itself can be queried for the IViewObject interface and have its Draw method called. The WPF WebBrowser doesn't expose this directly, but fortunately the Windows Forms WebBrowser does (alternatively you could host MSHTML directly)...

WPF Photo Print source code available

Fri, 22 Aug 2008 07:19:25 GMT

The source code for my WPF Photo Print utility is finally available... :)

Non-Topmost WPF Popup

Wed, 13 Aug 2008 17:06:40 GMT

The WPF Popup control is always "topmost" over other application windows. If you're happy with a dirty workaround to remove the Topmost state, you can derive your own Popup control similar to this...

WPF Photo Print

Tue, 29 Jul 2008 08:24:16 GMT

Here's a small WPF utility to help make ad-hoc photo printing a little easier. Some features: - No need to import your photos into a "walled" library (great if your photos are on a network share like mine, or just want an ad-hoc print from a memory card). - Never changes the source image and doesn't require version history. - All operations are additive and vector-based. Currently supports rotate (90° clockwise), crop (with aspect ratios) and straighten (up to 45° each way). - It's fast (no need to "Apply" changes or undo them later).

Silverlight soft-body physics

Tue, 24 Jun 2008 19:42:29 GMT

Here's a simple soft body physics demo based on Walaber's excellent JelloPhysics library. You'll need Silverlight 2 beta 2, but it's well worth it :)

LINQPad - Copy HTML to clipboard

Mon, 23 Jun 2008 15:58:07 GMT

Here's a useful bit of C# you can paste into your LINQPad statements to quickly hack together some HTML (could be useful for quick ad-hoc database reports).

A quick sample showing ASP.NET's System.Web.Routing being used with traditional WebForms :o)

LINQPad: Preview DELETE and UPDATE SQL before it executes

Fri, 18 Apr 2008 07:09:26 GMT

Newcomers to LINQ may get hesitant before perform a bunch of updates and/or deletes against their production data. Being more comfortable in Transact SQL compared to LINQ, they may want to see the SQL statements that would execute before actually calling SubmitChanges(). With a couple of extension methods, you can do exactly that: preview the SQL before it executes.

StackOverflow.COM

Thu, 17 Apr 2008 17:01:03 GMT

JA and Joel Spolsky join forces to kick the s*t out of Experts Exchange. I didn't know anybody else hated them as much as I did. I even toyed with the idea of creating a google frontend to append -experts-exchange to any search....

Batch Updates and Deletes with LINQ to SQL

Mon, 14 Apr 2008 08:26:52 GMT

A couple weeks ago, I read the article, LINQ to SQL Extension: Batch Deletion with Lambda Expression by Jeffrey Zhao. In case you didn't read the article, it discusses the downside of most O/R Mapping frameworks when it comes to multiple updates or deletes. He states the fact that a SQL statement for each row flagged as update/delete in the entity set is created. I went about implementing something similar to what Jeffrey envisioned and I'll explain some of the hurdles I had to overcome to achieve it.

Here's a simple codebehind-like concept for Silverlight 1.0, involving minimal changes to Visual Studio 2008's "Silverlight JScript Page" template code.

ASP.NET InlineDataSource

Fri, 14 Dec 2007 17:12:22 GMT

How many times have you wanted to use an ObjectDataSource but been too damn idle to create a new class? All you really want are its Selecting and Updating events and some magic dust in your codebehind, right? I may have just the thing for you...

Some handy C# 3.5 extension methods wrapping an ExpressionVisitor.
