For more information, see Delayed Rendering. The memory handle can be NULL, indicating that the window renders the data on request. For each format, the window calls the SetClipboardData function, specifying the format identifier and a global memory handle. To find out which window owns the clipboard, call the GetClipboardOwner function.Īfter emptying the clipboard, the window places data on the clipboard in as many clipboard formats as possible, ordered from the most descriptive clipboard format to the least descriptive. This function sends the WM_DESTROYCLIPBOARD message to the previous clipboard owner, frees resources associated with data on the clipboard, and assigns clipboard ownership to the window that has the clipboard open. To place information on the clipboard, a window first clears any previous clipboard content by using the Empt圜lipboard function.

Windows’ clipboard APIs are documented at MSDN, below excerpt gives an overview on how to set/get clipboard data: Cut and Copy Operations Silverlight’s clipboard API is ultimately implemented on top of the clipboard APIs of the underlying operating system.
Public static void SetText( string text, TextDataFormat format) Public static void SetText( string text) Public static void SetImage(BitmapSource image) Public static void SetFileDropList(StringCollection fileDropList) Public static void SetDataObject( object data, bool copy) Public static void SetDataObject( object data) Public static void SetData( string format, object data) Public static void SetAudio(Stream audioStream) Public static void SetAudio( byte audioBytes) Public static bool IsCurrent(IDataObject data) Public static string GetText(TextDataFormat format) Public static StringCollection GetFileDropList() Public static IDataObject GetDataObject() Public static object GetData( string format) Public static bool ContainsText(TextDataFormat format) Public static bool ContainsFileDropList() Public static bool ContainsData( string format) WPF’s Clipboard API supports more and extensible data format via IDataObject, and has helper functions for common formats like text, image, audio, and filedrop. The first time the clipboadData object is accessed, IE will prompt user to allow the script to access clipboard, and the setting is valid for the session only. Where sDataFormat is a string constant of "Text" or "URL", sData is a string, and bResult is a Boolean. IE provides clipboardData object that allows get/set/clear strings in system clipboard:īResult = (sDataFormat, sData) There is no cross browser, cross platform JavaScript API for clipboard access. Among them, the Clipboard APIs of JavaScript and WPF are particularly interesting, because we need to study the security lessons in JavaScript and try to be compatible with WPF.
We need to consider many factors while designing Clipboard API for Silverlight. In another word, the setting is per application, per session, for both get and set access to system clipboard, and it is not persisted. If user clicks yes, Silverlight will allow this and later GetText/SetText calls to succeed for this application during this session if user clicks no, the default, Silverlight will throw a SecurityException. it is user initiated and user grants clipboard accessįor the second case, when GetText or SetText is first called in an user initiated event handling, Silverlight pops up a dialog like the one below (UI may change at RTW):.the calling Silverlight application is an elevated trust application, or.GetText and SetText require either of following to succeed: It allows copy/paste Unicode strings to/from system clipboard.
