clipboard

问题 I'm working on a small clipboard manager which should remember recent copied text. I'm using Windows system messages for being notified when something has been copied to clipboard by WM_DRAWCLIPBOARD.

问题 I am able to copy data to the clipboard using a button press as seen below. But how can use the same behavior to get data from the clipboard? The paste event only works when I click into an input field or text area. I need it to be able to work using a button. I tried using window.clipboardData but it doesn't recognize it. Is there a way I can fire the Paste event through a button press? Copy(val) { const selBox = document.createElement('textarea'); selBox.style.position = 'fixed'; selBox

问题 I have this intermittent and incosistent problem which has been driving me crazy for a long time: In a program of mine, GetClipboardData(CF_TEXT) succeeds 90% (or so) of the time, but every once in a while it returns NULL. This is despite the fact that OpenClipboard() always succeeds (and return value checked) before calling GetClipboardData(CF_TEXT). Please note that the 90% success ratio is for the same exact page! (i.e. I know there is a CF_TEXT content there) Note: When it fails, I

问题 Why doesn't System.Windows.Forms.Clipboard.GetDataObject() return when calling it from a different thread and before the main thread stops, after calling System.Windows.Forms.Clipboard.Clear() within the main thread? I have written a sample program to explain my question: public class ClipboardDemo { [STAThread] public static void Main(string[] args) { Thread.CurrentThread.Name = "MAIN_THREAD"; Thread clipboardViewerThread = new Thread(RunClipboardViewer); clipboardViewerThread.Name =
