LINQ brings. Sorting in Linq Of course, you can use the by function in IEnumerable (of T), but I do not recommend that. You can use exactly the same syntax as T-sql: Dim Data As String() = {"a", "b", "d", "c"}Dim Query = From O In Data Order By O Descending '这就是核心'输出信息For Each QItem In QueryConsole.WriteLine(QItem)Next Cross-array queries in LINQ In the current Visual

Api functions are the cornerstone of building Windws applications. For every Windows application development tool, the underlying functions provided by API functions call Windows Api functions indirectly or directly, at the same time, in order to achieve function expansion, interfaces for calling WindowsAPI

Relatively speaking, the use of events is relatively simple. Before use, we must first define the event, which means to notify Visual Basic of what events are called. An event may have its own parameters. For example, a command button has a click event, which has no parameters. In addition, the text editing box has a keypress event, which processes related content using a value named "keyascii. Defining an

real software. I've had this problem recently in terms of data access. In fact, every data access example I've seen uses SQL statements to read from or write to a relational database (for example, Microsoft SQL Server™). However, in a real-world environment, this is not a desirable programming method except for a limited number of small systems. A reasonably structured n-tier application uses stored procedures instead of SQL statements for data access. A stored procedure is conceptually simil

Note that when you access the array, ' Use of the default property. HostForm.Controls.Remove (Me (me.count-1)) Me.List.RemoveAt (me.count-1) End If End Sub Create a public event handler The final step is to create an event handler to handle the public events of the array. In this case, we'll create a way to handle the button's click event,

Elements of an integrated development environment Basic working environments often refer to the integrated development environment or the IDE because it integrates many different functions in a common environment, such as design, editing, compilation, and debugging. In most traditional development tools, each feature is run with a separate program and has its own interface. In this section, the following
