This sample consist of a command line showing how to interact with a database.
|

|
||||
The DataReader object is somewhat synonymous with a read-only/forward-only cursor over data. The DataReader API supports flat as well as hierarchical data. A DataReader object is returned after executing a command against a database. The format of the returned DataReader object is different from a recordset. For example, you might use the DataReader to show the results of a search list in a web page.

The sample queues up an asynchronous method call that is executed by a thread from the thread pool managed by the Common Language Runtime. The method "does some work" and then sets an event indicating that the work has finished. The main thread waits on the event and then exits.

Multiple Document Interface (MDI) applications have a single, primary window (the parent window) that contains a set of windows within its client region (child windows). Each child window is a form that is constrained to appear only within the parent. Children typically share the menu bar, tool bar, and other parts of the parent's interface. Secondary windows like dialog boxes are not constrained to the parent window's client region.

Windows Forms supports menus and context menus. Main menus are displayed on a menu bar that is located immediately below the title bar of a form. The menu bar contains top-level menu items that are used to group related submenu items. For example, by clicking a '''File''' top-level menu item, you can display menu items that are related to file operations. Menu items typically appear as commands for your application (such as '''New''' and '''Open'''),but they can also appear as separator bars and submenu items. You can display a check mark next to a menu item to display the state of a command or a the state of a feature in your application. In Windows Forms, main menus are represented by the '''MainMenu''' control.
|
||||
|
||||
Context menus can be displayed for a specific control or area of your form. They are typically accessed by clicking the right mouse button. In Windows Forms, context menus are represented by the '''ContextMenu''' control.
