HTML5 IE9 Bug: SELECT box is Un-Selected using Mouse if CSS modifies position on hover

I recently encountered this rather strange bug that only shows up in Internet Explorer 9 (haven’t tried 10, but likely there too,) but works just fine in IE8, Firefox, Safari and Chrome. Generally the HTML/CSS markup for an individual page within a normal web application can get pretty complex, so this bug took me a while to figure out what it was. Apperently, if you have a <SELECT> box contianed within a <TABLE> (which is done fairly often with data entry interfaces,) and you have ... [More]

Silverlight with WCF RIA Services Throws "Project File ... Not Found" Error When Compiling in Visual Studio 2010 RC

While working with the Silverlight Business Application template in Visual Studio 2010 RC I discovered a peculiar issue that if the project specified as the "WCF RIA Services Link" for the Silverlight Project can not be found a compile time error of "Project File ... Not Found" will be generated. This is a very cryptic error message since it's the same message that gets thrown if you delete a Project File (.csproj or .vbproj) from the hard drive but it's still references within the Solution File...

.NET 3.5 SP1: DataContractJsonSerializer Bug

Update 9/16/2008: After too long, I finally tried uninstalling SP1 and reinstalling it and that fixed the issue. I'm glad it's fixed now! I haven't seen any other suggestions for fixing this, and I first tried repairing the installation, but only an uninstall and reinstall fixed it. Hope this helps solves anyone elses headache with this issue.   A few months ago (back in February actually) I blogged showing how to use the new DataContractJsonSerializer to serialize your .NET objects to JSON...

ASP.NET 2.0: RewritePath breaks HyperLink's ImageUrl in App_Theme file when path with slash is rewritten

Rewriting a path with a slash ("/") in it will cause a HyperLink's image specified in the ImageUrl property within an App_Theme file to not be displayed. This can also lead to a "Cannot use a leading ..." error when running the website within IIS. Here's a screenshot of the issue occuring:   This is kind of a strange bug, since doing the same thing with an Image works just fine. It's only the HyperLink that breaks. I experienced this issue the other day, and it took me a little bit ... [More]

Virtual Earth 6 Bug: GetDirections breaks when Start and End Address are the same

When using the new GetDirections method to get multi-point driving directions everything works fine if the Start and End address are different. But it shows unexpected results on the map when plotting a multi-point route that has an End address the same as its Start. Here's some sample code to reproduce this issue: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" ""> <html>  ... [More]

Virtual Earth 6 Bug: ShowSwitch parameter of LoadMap method no longer works

Update 12/29/2007: This is no longer a bug. It has been fixed since I originally posted this. This is the second bug in Virtual Earth 6 that I've found today. It appears that the showSwitch parameter of the LoadMap method is broken and no longer works. As the documentation states: "A Boolean value that specifies whether to show the map mode switch on the dashboard control. Optional. Default is true (the switch is displayed)." Below is a screenshot showing what is... [More]

Virtual Earth 6 Bug: Zoom buttons in wrong place with multiple maps on the same page

I'm currently working on adding Virtual Earth v6 support to Web.Maps.VE, and I have found a bug in VE6. When there are multiple maps on the same page the images for the zoom in/out buttons of the dashboard are not getting displayed on the correct map. I circled them in red in the screenshot below... This is kinda strange behavor.

I Found a bug in the Rating control in the Atlas Control Toolkit

I found a bug in the current release (60731) of the Atlas Control Toolkit. The bug I found is caused when you use the Rating control within a User Control and you have multiple instances of your User Control on a page. I hope this bug gets fixed soon, it sucks for someone who likes to make things reusable using User Controls. View the Work Item I add over at CodePlex

I found a bug in SQL Server 2000...

Well, I didn't find a new bug, but it is the first time I discovered a bug in SQL Server by just doing my everyday job. I'd post the code for the SQL Server user defined function that I wrote if I could, but I can't (confidential). Its nice to have a reminder once in awhile that even Microsoft's software has bugs. Server: Msg 8624, Level 16, State 8, Line 1 Internal SQL Server error.
