Ascii Table - ASCII character codes and html, octal, hex and decimal chart conversion. Join Example: LINQ. LINQ provides a fully featured query language. It offers the join operation. As with other query languages—such as SQL—joining matches every element in two collections based on some condition. Example This first example shows the Join extension method from the System.Linq namespace.
And then it shows the equivalent join query expression syntax. Extension Method Tip:You can read in painful detail how query expressions are translated in the chapter on Expressions (7) in the C# specification. But:This material is complex, tiresome and not all that useful for actual development. With the Join method, we provide delegates as arguments. So:If ints1 contains an element of value 4, it is selected only if there is an element of value of 5 in ints2. Int Array In my view, the second syntax in the example—with the query expression—is easier to read. MS-DOS/MSDOS Batch File troubleshooter.

Batch File to Append Date to file name Saturday 24 Feb, 2007 - 21:49pm | 36 comments | A DOS batch file (file with extension .bat) can be a very effective way to automate a series of file operations.
You can schedule the batch file to run at a specific time, and automate, say, a series of operations such as copying, moving, deleting or renaming files. You can create a batch file in any text editor like notepad and just save the file with an extension of .bat. In windows, if you open a DOS prompt, type edit and hit return a retro text editor will open which you can also use. The batch file code below will copy all microsoft excel files (.xls) from the current folder into a folder called "import" and append the current date in yyyymmdd format to the filename.

Oleg Sych. How to read and write a file to or from a BLOB column by using ADO.NET and Visual C# .NET. This article describes how to read and write data from LongVarBinary BLOB columns in a database table. This article contains examples of both the SqlDataAdapter class and the OleDbDataAdapter class. The only differences between the two classes, other than the class names, are the connection strings and the declaration of SQL parameters; the fundamental technique for retrieving the BLOB data is the same.
The sample code in this article uses a sample record that is added to the Categories table of the Northwind database. After you use this sample, you may want to remove this record: Enter the following command in SQL Query Analyzer, and then press F5: use Northwind delete from Categories where CategoryName = 'Test' Requirements.

LINQ Distinct: IEqualityComparer and Func extension method Implementations - Carl's Blog.
As you may know when working with LINQ there is a method that allows one to return distinct elements from a sequence. Two prototypes are supported: Distinct<TSource>(IEqualityComparer<TSource>)Distinct() Unlike most sequence operations that take some form of a Func parameter, the Distinct() method takes an instance of an IEqualityComparer Type. It is the implementation of this Type that I will be discussing which will hopefully provide some insight into why this approach has been taken.
I am going to demonstrate the Distinct() method using the following class definition: A distinct product is one defined where the Reference and ProductVersion values are unalike. Ecosytem. Drawing class diagrams in VP-UML.
