updating

问题 I have recently created a website that allows users to upload images and then let that user and other users of the website rate the images from 1-10. Everything is working correctly. When the user rates an image this is saved and then another random box is generated and presented to the user. This works by adding the new box id (randomly generated) to the query string. This allows for the user to navigate back to the images that they have just seen. My problem comes with updating the page.

问题 I am using Python and I have a JSON file in which I would like to update a value related to a given key. That is, I have the my_file.json containing the following data {"a": "1", "b": "2", "c": "3"} and I would like to just change the value related to the b key from 2 to 9 so that the updated file look as like: {"a": "1", "b": "9", "c": "3"} How can I make that? I tried the following but without success (the changes are not saved to the file): with open('my_file.json', 'r+') as f: json_data =

问题 I have two sprites which a flush against each other. I'm moving one of the sprites around using a SKAction and moving the other sprite using the update function. Every time the update function is called, it calculates the position the second sprite needs to be at so that it continues to be flush against the first sprite. However, it seems the update function can not move the second sprite fast enough, as a gap appears between the two sprites. I assume the SKAction repositioning of the first

问题 First of all, this has nothing to do with the browsers cache, I'm 100% sure about it. I really really hope you can help me with that. I'm trying to fix this for more than 10 flat hours now. :/ So I was updating and deleting some files (jpg,css,js and ico) using my ftp account. After the files were uploaded, I downloaded them again using my ftp account. So, I can confirm the files were uploaded correctly. But now comes the weird thing: I start a computer (different ip, never visited my website

问题 I have a bank account file that the program should be able to read. This function works as of now with the use of ifstream. But I want the program to read the 6th line of the text file (which has the value 'balance') and then update it as needed (delete and replace with new value). I used a for loop to find traverse through the lines. But how do I update it when needed? (Withdrawal and deposit of money updates the balance) This is the code I have for now: ifstream file; string line; file.open

问题 I have kind of hypothetical question (at least for now :)) Let's say I create list based on some custom content-type. I add some 1000 items into that list (in production). Then customer comes and he say that he need to modify that custom content type. What happens to list if I modify custom content type? Will it be updated automatically (I doubt) ? And what about already created list items? Do any of you have some experience with this? 回答1: So a couple of issues regarding content types: First

问题 What's the best way to terminate a program and then run additional code from the program that's being terminated? For example, what would be the best way for a program to self update itself? 回答1: You have a couple options: You could use another application .exe to do the auto update. This is probably the best method. You can also rename a program's exe while it is running. Hence allowing you to get the file from some update server and replace it. On the program's next startup it will be using
