With Windows Forms, you can create powerful Windows-based applications. The following topics describe in-depth how to harness the power of Windows Forms to display data, handle user input, and deploy your applications easily and with enhanced security.

Creating a New Windows Form Contains links to topics that describe basic concepts for creating Windows Forms applications. Changing the Appearance of Windows Forms Contains links to topics that show how to change the appearance of Windows Forms applications. Windows Forms Controls Contains links to topics that describe and show how to use Windows Forms controls and components. You can also data-bind existing controls to data by dragging objects from the Data Sources window onto existing controls.

Another type of data binding you can manage in Windows Forms is settings. Most apps must retain some information about their run-time state, such as the last-known size of forms, and retain user preference data, such as default locations for saved files. The Application Settings feature addresses these requirements by providing an easy way to store both types of settings on the client computer.

After you define these settings by using either Visual Studio or a code editor, the settings are persisted as XML and automatically read back into memory at run time. After you have written your app, you must send the app to your users so that they can install and run it on their own client computers.

When you use the ClickOnce technology, you can deploy your apps from within Visual Studio by using just a few clicks, and provide your users with a URL pointing to your app on the web. ClickOnce manages all the elements and dependencies in your app, and ensures that the app is correctly installed on the client computer.

ClickOnce apps can be configured to run only when the user is connected to the network, or to run both online and offline. When you specify that an app should support offline operation, ClickOnce adds a link to your app in the user's Start menu. The user can then open the app without using the URL. When you update your app, you publish a new deployment manifest and a new copy of your app to your web server. ClickOnce will detect that there is an update available and upgrade the user's installation.

No custom programming is required to update old apps. Skip to main content. This browser is no longer supported.
