All new projects start out the same way: a project folder is created, subfolders are created for different artifacts, assemblies are added, and so on. A new Visual Studio solution doesn’t take into account best practices such as a branchable folder structure or how best to organize your referenced assemblies, where your automated build process should be located, or which common reusable frameworks and tools you use in every project.
Even with all the advancements in technology, two important factors for enterprise desktop development still hold true today. There remains a need for better performance and an appealing user interface (UI). Today, you've got the opportunity to win a free license of ComponentOne Studio for WinForms controls (valued at $1,195.00) that will help you do just that. (Note: contest is complete and winner awarded)
Each year in late February, Microsoft MVP's who've been lucky enough to get their MVP status "renewed" for the year get to attend the MVP Summit conference for about a week of total immersion into everything "Microsoft" in their particular discipline. I've been to every Summit since 2005, and almost without fail, they are absolutely worth the effort and expense. This year's Summit was no exception.
As a programmer, I've been a "performance freak" for a very long time. I believe in extensive testing and good metrics -- just like scientists who practice good science. Some people think I'm nuts, but I just tell them, "You become interested in performance when you're fortunate enough to have to worry about it". If you can think big, then you need to worry about performance, period.
BrowserID is a distributed system that allows users to use their email address as the login name and password. It is much simpler than OpenID, and also much easier for developers to integrate into their web sites. There is also no need to store passwords or password hashes, since all authentication is performed by the offsite provider.
Silverlight RIA Services has undergone steady improvements, and it is included With Silverlight 5.0. WCF RIA Services simplifies the traditional n-tier application pattern by bringing together the ASP.NET and Silverlight platforms. RIA Services provides a pattern to write application logic that runs on the mid-tier and controls access to data for queries, changes and custom operations.
Developers often work with unstructured data such as text documents, images, and videos. This unstructured data is often stored outside the database, separate from its relational structured data. This separation can cause data management complexities.
FILESTREAM integrates the SQL Server Database Engine with an NTFS file system by storing varbinary(max) binary large object (BLOB) data as files on the file system. Transact-SQL statements can insert, update, query, search, and back up files.
HTML5 offers two new objects for storing data on the client:
localStorage - stores data with no time limit - and
sessionStorage - stores data for one session.
This was previously done with cookies. Cookies are not suitable for large amounts of data, because they are passed with every request to the server, making the process slow and ineffective.
Eloquera DB is a 100 percent .NET managed code object database that incorporates the best features of relational and object databases and overcomes their deficiencies. The database can be installed as a Windows Service (like SQL Server), but it can also be run in embedded "Desktop" mode. Here we show how you can use EloqueraDb in Desktop mode in an ASP.NET Web Application.
I've always been interested in fractal geometry. When Benoit Mandelbrot died last year, I was very sad. I still have his book, "The Fractal Geometry of Nature" which I bought back in the 1980's. The color graphics in the book (especially considering available computing power then) are stunning. I almost failed 9th grade algebra. Math didn't become interesting to me until I started programming and studied fractal geometry. Now, math is beautiful!
QR-Codes have become quite popular in the last few years, and there are QR-Code reader apps for virtually every mobile device that has a built-in camera.
These are mostly used for web urls to make it easier for mobile device users to navigate and bookmark a page with their mobile browsers. Of course, other information can be QR-encoded too.
Each year I like to play with the text of the president's State of the Union speech to get the word frequency. You can get some pretty good information from how many times certain words are used. This year I do it via LINQ as a fun programming exercise.
Many ASP.NET developers operate under the mistaken assumption that you need a WCF Service to handle JSON. Quite the contrary; ASMX services are happy to emit JSON. Here's how.
Up until recently, you could use the Yahoo Term Extraction Webservice to have the Yahoo Term Extraction API generate a list of valid key phrases from entered text or by reading a web page. However, Yahoo has announced that this service is deprecated and will only be available until March, 2012. All Yahoo APIs have now been folded into the new YQL model and use the same endpoint url, http://query.yahooapis.com/v1/public/yql.
We live in a world where nasty people with nothing better to do come up with all kinds of tricks to install nasty Trojans, Viruses and RootKits on our computers. Intelligent surfers can avoid most of this stuff just by using common sense - but it seems that for some, that's in short supply these days.
Often I need to convert a List of a certain type to a CSV string, or to a DataTable. Here I provide four extension methods:
1) public static DataTable ToDataTable<T>(this IList<T> data) (List<T> to DataTable.
2) public static string ToCsv<T>(this IList<T> data) ( List<T> to CSV string.
3) public static string ToCsv(this DataTable dt) ( DataTable to CSV string.
4) public static void WriteDelimitedFile<T>(this IEnumerable<T> list, string logfile, string delimiter)
.NET Developers often have to create their own SQL Server databases and be familiar with database schemas, tables, and the use of T-SQL stored procedures and joins. However, a weak point is often how to optimize the database with indexes. We summarize the use of the Database Engine Tuning Advisor in creating statistics and indexes based on an existing workload
Google has some search operators than many people are not aware of. If you suffix a google search url with one of these, you can restrict results to those that got indexed as little as one minute ago.

I wrote a small VB program that writes a simple text file 1000 lines long, and each line has 50 numbers (or words) separated by commas. I then have an Excel spreadsheet that I put this data into. I go into a particular "data input" sheet, in cell A3 let's say, and I do the Data - Get Data stuff. When the window about the "tab" vs. "comma" delimiting comes up, I switch it from ta...
I am trying to print the contents of a jQuery UI dialog that has text boxes with values in the text boxes. The text box values are assigned using jQuery when the dialog is opened.

I would like to know very much how I can get those text b...

When a blank form opens (automatically) for entry of the next record, I want the user to have the option of calling up another record, in case it needs to be edited. The "search" and "go to" buttons do nothing: the data flashes in the fields, and then instantly disappears. I really cannot believe that Access provides no simple way of searching for a record and showing it in the proper form. So I ...
