Using the Clipboard

The Code Project

The clipboard is where your data is stored when you copy or cut some text or an image or a file or a folder. The clipboard is common across processes, which means we can use the clipboard as a mechanism to transfer data between two processes. Win32 gave us a Clipboard API with functions like OpenClipboard and GetClipboardData which most of you might be familiar with. In .NET Microsoft has encapsulated the functionality of most of these functions into some classes. The most prominent of these classes is a class which has been named aptly as Clipboard. It's a very simple class with just two functions. In this article, we'll see how to copy/paste text, images and also how to maintain clipboard data in multiple formats.
