Clipboard

WPF’s RichTextBox control is quite powerful, and very handy if you need to accept rich text input. However, one of its features can become an issue: the user can paste an image. Depending on what you intend to do with the text entered by the user, you might not want that. When I googled for a way to prevent that, the only solutions I found suggested to intercept the Ctrl-V keystroke, and swallow the event if the clipboard contains an image.

Oops… 2 months already since my previous (and first) post… I really have to get on a more regular schedule ;) If you’ve ever tried to use the Clipboard.GetImage method in WPF, you probably had an unpleasant surprise… In fact, this method returns an InteropBitmap which, in some cases (most cases actually), can’t be displayed in an Image control : no exception is thrown, the image size is correct, but the image either appears empty or unrecognizable.
