六月ゝ 毕业季﹏ 提交于 2019-11-30 10:12:59
问题 This is quite a simple question: I just need to open a file (this filename is galfit.feedme). I can view the file with view galfit.feedme when I'm in the directory, but I do not know how to edit this file and then save the edit. How do you do that? 回答1: Normal text editors are nano , or vi . For example: root@user:# nano galfit.feedme or root@user:# vi galfit.feedme 回答2: For editing use vi galfit.feedme //if user has file editing permissions or sudo vi galfit.feedme //if user doesn't have

I work with Nodejs Express routes and Mongoose to persist data. I did the core routes CRUD operations with no problem. However, when I try to perform some operations on one of the fields of the Model and then try to save the Model with model.save it says about .save() method: "undefined is not a function" So, here's the code. The snippet number (1) works just fine: router.put('/:myId', function (req, res, next) { var ourUpdateData = req.body; Model.findOne({myId: req.params.myId.toString()}, function (err, foundModel) { if (err) throw err; if (ourUpdateData.fieldA) foundModel.fieldA =

Save values before close the app?

南楼画角 提交于 2019-11-30 07:39:34
问题 I want to save some values before i closed the app. But i don't know if i must create a new file(.txt) and save it in; or i just can change strings.xml file and when i open app next time the saved values will be the right saved values or will be walues which i define them before first using.

How to ensure that data doesn't get corrupted when saving to file?

前提是你 提交于 2019-11-30 07:22:43
I am relatively new to C# so please bear with me. I am writing a business application (in C#, .NET 4) that needs to be reliable. Data will be stored in files. Files will be modified (rewritten) regularly, thus I am afraid that something could go wrong (power loss, application gets killed, system freezes, ...) while saving data which would (I think) result in a corrupted file. I know that data which wasn't saved is lost, but I must not lose data which was already saved (because of corruption or ...). My idea is to have 2 versions of every file and each time rewrite the oldest file. Then in case

how to make save / load game functions in pygame?

随声附和 提交于 2019-11-30 07:22:18
I need to make save / load game functions for my rpg. I can save the location of my player, but what I want is to freeze the entire screen at one point like it is done in emulators like vba and snes9x. Or maybe to make save locations where I can save the game and start again from. Can anyone tell me how you do these things? any code is welcomed even theorybased pseudocode. You can use pickle to serialize Python data. This has nothing to do with pygame. So if your game state is completely stored in the object foo , to save to file "savegame" ( import pickle first): with open("savegame", "wb")
