Can aborting a process without resetting the clipboard chain cause trouble?

由 大兔子大兔子 提交于 2019-12-08 08:48:29
问题 I've got a program that calls SetClipboardViewer at startup to register for clipboard change notifications. At shutdown time, it will call ChangeClipboardChain to remove itself from the chain correctly. This is all great as long as the program runs normally. But that's got me wondering, what happens if the program gets aborted, either by me killing it under the debugger, by a crash, or by the user killing the process because something went wrong? Then the cleanup never happens. Can that cause

问题 I am copying cells from an excel document to the clipboard so they can be inserted as an image elsewhere.

Here is my code: tempWorkSheet.Range[tempWorkSheet.Cells[1, 1], tempWorkSheet.Cells[3, 3]].CopyPicture(Excel.XlPictureAppearance.xlScreen, Excel.XlCopyPictureFormat.xlPicture); // returns true var test = Clipboard.GetDataObject().GetDataPresent

When I create a new Android Virtual Device and run it for the first time in Eclipse, I have noticed that it activates my webcam and takes a picture. This picture is saved to my clipboard. But I was wondering if this is normal and happens to anyone? INFO: Android Development Toolkit Version: 16.0.1.v201112150204-238534 Android 4.0.3 API level 15 Running on Windows XP EDIT: Tracked it down to what I think is the SDL_app process. Also when I disabled my clipboard and started it up I got this printed to the terminal: [2012-01-26 05:12:12 - Emulator] emulator: ERROR: camera_device_start_capturing:

IE11 pasting clipboard data to an input element annoyance

由 一曲冷凌霜 提交于 2019-12-08 05:23:16
问题 I had some javascript that basically listened for the "paste" event on a particular input text element. I did this event binding via jQuery. Now, in previous versions of IE, things worked great. But after upgrading to IE11, the behavior is different. Scenario: I'm copying and pasting multiple keywords separated by a CR and LF (multiple rows in a spreadsheet). In javascript, within the "paste" event handler, I read the clipboard data and convert all the CR/LF characters into a single comma,

问题 Is there a way to send multiple lines of text to the clipboard using javascript? IE, I want to send: abc def ghi and not abcdefghi (and although right now i need to learn how to do it in Javascript, I would not mind hearing how it is done in other languages, like python) 回答1: Send it as one string with carriage return and line feed characters in it, as Russ suggested. You replied to Russ that, "it does not work": what's the symptom of it not working? If you're copying from the clipboard into

问题 I'm using Dart to develop a personal whiteboard Chrome app and it is sometimes useful to be able to quickly copy and paste an image (e.g. a slide from a presentation, a diagram or a handout) so that I can add notes over the image while teaching a class or giving a presentation.
