Advanced Basics: Windows Forms Controls


Build a control that allows the user to drag and drop other controls onto the new control at run time, and allow the user to move the control around on a form, all in Visual Basic.

Application Architecture in Windows Forms 2.0

Applications have special support in Windows Forms. For starters, you can manage and tailor your application's lifetime, and, when the work flow is disrupted by an unhandled exception, you can choose from several methods of response. Then, there are several application models that you can employ, including Single Document Interface (SDI) and Multiple Document Interface (MDI) applications, each of which can support either multiple-instance or single-instance mode, the former the VS05 default and the latter requiring special consideration. All applications, however, can discover and use a wide variety of information about the system and environment they execute in.

Application Architecture in Windows Forms 2.0-Single-MDI Applications

Consider an MDI application like Microsoft Excel; files opened from the file system (by double-clicking) are all opened as separate child windows within the parent Excel window.7 For the first instance of an MDI application to open a new child window to display the file that was passed to the second instance of the application, the second instance must be able to communicate with the initial instance.

How to programmatically add controls to Windows forms at run time by using Visual C#

Create a Windows Forms Application
Start Visual Studio .NET or Visual Studio 2005 or a later version, and create a new Visual C# Windows Application project named WinControls. Form1 is added to the project by default.
Double-click Form1 to create and view the Form1_Load event procedure.
Add private instance variables to the Form1 class to work with common Windows controls. The Form1 class starts as follows:

How to Localize Windows Forms and Change the Language at Runtime

Localization is the process of customizing your application to a particular language, culture or locale. Visual Studio provides support for localizing Windows Forms with much ease. In this article, we will see how to localize windows forms and give the user the ability to change to his preferred language at runtime.
When you run a localized application, the appearance is determined by two culture values. The UICulture property is used to specify which resource files will be loaded for the form. The Culture property, on the other hand, determines how strings such as dates, numerals, and currency amounts are formatted.
Let us see the steps required to create a localized form. You can then expand this example and adopt the same approach for the rest of the forms in your project

Localizing Windows Forms

The Visual Studio project system provides considerable support for localizing Windows Forms applications. There are two ways to generate resource files using the Visual Studio development environment: one is to have the project system generate the resource files for localizable UI elements such as text and images on the form. The resource files are then built into satellite assemblies. The second way is to add a resource file template and then edit the template with the XML Designer. A reason for doing the latter is to make localizable strings that appear in dialog boxes and error messages. You must then write code to access these resources.

This walkthrough topic demonstrates both processes in a single Windows Application project.

You can also convert a text file to a resource file; for more information, see Resources in Text File Format and Resource File Generator (Resgen.exe).
