An application for users to play Circular Chess over the internet based on Silverlight, ASP.NET Ajax, WCF Web Services and LINQ to SQL

This article shows you how to bring revolutionary UI provided by MS Silverlight to the world of ASP.NET control development with the help of recent released ASP.NET 3.5 Extensions CTP

Okay...I'm going nuts about this and don't know why this is happening. Why is "Generation of designer file failed"?

I've a regular ASP.Net C# web application project in Visual Studio 2008. I've one master page under folder called "Master". When I add a new Content ASPX page using this master page (the master page has absolutely nothing in it except the default HTML tags and a form) and save the content page, it gives the following:

 

This is driving me nuts. :(

I have already performed the following operations but nothing has helped:

• Deleted the webform1.designer.cs file and right click on the .aspx  and select "Convert to Web Application". Upon doing this, it gives the same dialog as above.
• Tried devnev.exe /resetsettings with no luck.
• Checked the permission on the folder, I've full permission.
• Tried creating an aspx page without Master page and it works FINE. i.e I don't get the dialog above.

So, I have concluded (without any resolution) that this has something to do with the Master page. I don't know what's wrong.

Is there anybody else facing the similar issue?

 

Update (12/27/07 1pm EST):

Once you get the error above, it won't go away from the Error List unless you close the Studio and reopen the project. Nuts, really!

I've been really diving head first into the CTP of the ASP.NET MVC Framework as well as getting my hands dirty with LINQ to SQL, as I'm sure many of you have been.  During this time, I hit a road bump and was banging my head against the wall trying to figure this one out with my LINQ to SQL knowledge.  In a previous post, I wrote about using a Repeater control to display a LINQ to SQL entity with a parent child relationship.  The example we used was the concept of a FAQ engine with a FaqCategory table and a Faq table.  The relationship is shown below.

Each table has a "DisplayOrder" field which, as the name implies, is used to sort the entities for display purposes.  Sorting the parent table (in this case FaqCategory) is straightforward.  However, accomplishing this while also sorting on the child table was not as straightforward.  We have a couple of options available to us when we need to sort the child entity of a hierarchical relationship.

Method 1 - Using the DataLoadOptions class

The first method, and the one that I chose for this specific implementation, is to use the very handy DataLoadOptions class. This class really hasn't gotten as much attention as it deserves in recent LINQ to SQL blog posts, but it really has some great features that let you customize how data is loaded.  You can set entities that should be loaded together which can decrease roundtrips to the database server and increase performance.  The Faq implementation is below with sorting on the child table.

 

This will tell the data context to always load the Faq table along with the FaqCategories

Method 2 - Projecting the Child Entity

The other method is simply projecting the child entity itself.  I'm slowly but surely getting used to the LINQ to SQL syntax.   This implementation is displayed below. 

Special thanks to Joe Albahari for his help with my LINQ to SQL syntax! 

Hope this helps!

Legion is a grid computing platform that uses the Silverlight CLR to execute user definable tasks. It provides grid-wide thread-safe operations for web clients. Client performance metrics, such as bandwidth and processor speed, may be used to tailor jobs. Also includes a WPF Manager application.

Just before Christmas as well :-)

Download DSA 0.3

New features for this release include:

• Probability Search
• Power algorithm
• Greatest common denominator algorithm
• Reverse words algorithm
• Set collection (will be renamed to OrderedSet in DSA 0.4 and an unordered Set will be introduced in DSA 0.4 as well)
• Sequential search
• Merge sort
• Merge ordered

Some other not so major features include:

• Pseudo code for around 75% of everything to enable easy language ports (100% of everything will be in DSA 0.4 - the paper to screen conversion is taking a while)
• Queue and Stack have been dropped - DSA will only support collections not in the BCL
• ArrayList is being dropped in DSA 0.4
• Complete XML documentation for every public algorithm/data structure - also private methods are XML doc'd as well.

Also this is the first release to include offline documentation (or documentation of any kind excluding XML docs).

Download DSA 0.3

DSA 0.4

This release will be out mid February and will introduce some new key algorithms and collections.  I am in the process of finalizing the features to be added in DSA 0.4 but you can expect more tree data structures as well as balancing algorithms to further optimise tree data structures.  I will post something when this is finalized - will be the back end of December.

Thank you for your support and if there is anything you would like to suggest then it is not too late...also if you find any issues please let me know.

I had to reboot the machine and now it's working fine. Rick is also facing some issues with VS 2008. Hopefully, this will be cured soon.

Regular readers might remember my whole Converting a project to Unicode series in nine parts:

Part 0 (The introduction)

Part 1 (Business before pleasure)

Part 2 ('Sorry, you're not my type.' 'Um, maybe I could change that?)

Part 3 (Can I quote you on that?)

Part 4 (/Delightful, /Delicious, /DUnicode!)

Part 5 (Are we there yet? Well, not just yet)

Part 6 (Upon the road not traveled)

Part 7 (What does it mean to fit things to a 'T', anyway?)

Part 8 (Fitting MSLU into the mix)

Part 9 (The project's postpartum postmortem)

One of the lingering questions in many people's minds (now that they can't ask anymore why no useful samples exist!) is why there aren't more tools to help with this process.

Luckily, MVP Mihai Nita is not sitting around waiting for such tools to be built!

Take a look over on his site at ToUnicode – Automating some of the steps of Unicode code conversion (Windows), for a tool that takes many of these steps and tries to automate them.

This strikes me as an effort that can only get better over time. and one that needs to keep on getting better as the need becomes greater and greater....

Now this does not let the people who ought to be doing more here off the hook, believe me. But the better the external efforts get, the more foolish the internal folks look for not doing more here.

And Visual Studio just got served!

Thanks Mihai -- I not only owe you a book, I now also owe you a beer! :-)

WPF NavigationWindow is a very handy class that allows you to easily build Vista-like wizards, or any kind of window that resembles the browser-style navigation:

  

The NavigationWindow will automatically handle the Backspace, Back/Next keys and perform the appropriate navigation on the window pages.

If you're combining this class with the WindowsFormsHost to integrate WinForms controls, you may hit a very annoying bug: if there are textboxes in your WinForm control, hitting Backspace while editing the input on it will cause the navigation window to navigate back, instead of deleting the text on the TextBox. Yikes! ...
