How can I keep undo history after saving on Visual Studio Code

由 做~自己de王妃 提交于 2020-05-10 07:09:09
问题 I'm using latest version of VS code (1.9.0). After I undo (ctrl+z) something, and save the file (ctrl+s), then I cannot redo anymore (ctrl+y). I would like to go back and forth during the editor is running same as Sublime or other editor. Can anyone solve this problem? Thank you. 回答1: Undo/redo on a kept open file That normally should work. If not, it could be an issue with one of your installed extensions. Try to start Visual Studio Code on a terminal/command line with code --disable

Oracle redo日志切换频繁

由 痴心易碎 提交于 2020-04-07 11:26:03
先看AWR top5 整理来看，系统没有瓶颈。 不过出现log file switch (checkpoint incomplete)等待事件，说明redo日志过小，导致redo频繁切换，从而导致数据库某些大更新操作无法正常checkpoint。 解决思路： 增加日志组大小设置为500MB，结合reuse使用。 最后，记得给数据库来个全备！ 来源： oschina 链接： https://my.oschina.net/u/2622252/blog/667071

How to configure IntelliJ (also Android Studio) redo shortcut to CTRL+Y instead of CTRL+SHIFT+Z?

由 不羁的心 提交于 2019-12-20 08:11:48
问题 The default IntelliJ / Android Studio "Redo" action shortcut is CTRL + Shift + Z and this is a common problem for Windows users. A bigger problem is CTRL + Y is mapped to the "Delete line" action - and this causes the undo stack to be lost. To solve this issue, how can the "Redo" shortcut be changed to CTRL + Y in IntelliJ? 回答1: Open Settings (press CTRL + ALT + S ) Click Keymap on the left list. There is a combobox that contains keymaps. Select one of them (default means IntelliJ of course.

Redo for loop iteration in Python

由 岁酱吖の 提交于 2019-12-17 19:17:02
问题 Does Python have anything in the fashion of a "redo" statement that exists in some languages? (The "redo" statement is a statement that (just like "break" or "continue") affects looping behaviour - it jumps at the beginning of innermost loop and starts executing it again.) 回答1: No, it doesn't. I would suggest using a while loop and resetting your check variable to the initial value. count = 0 reset = 0 while count < 9: print 'The count is:', count if not someResetCondition: count = count + 1

问题 I am trying to write a text editor using RichTextBox . My concern is now about Undo and possibly Redo features of RichTextBox.
