ownership

问题 Do I use the Owner , OwnerItem , or the Container property? What if the ToolStripMenuItem is a member of another tsmi, which in turn is a member of another tsmi, etc.? The purpose of this is to be able to add an event handler that gets at the TreeView that has the ContextMenuStrip that has that ToolStripMenuItem . Abstracting a bit, is there a general way to get at the owners of controls, until you reach the one you're interested in? Just cast and hope? 回答1: use ToolStripMenuItem1

问题 As the title mentions - How can I change the ownership of a Google Play Console Developer's Account. Change the ownership means to associate the developer's account with a different Gmail account & let the previous association be let go (and possibly not pay the $25 USD registration fee again). Note : There is a similar question asked but I think it's incorrectly marked as a duplicate of a question which doesn't answer the question. (It answers How to transfer apps to another account) . I

问题 According to The Rust book: Each value in Rust has a variable that’s called its owner. There can be only one owner at a time. When the owner goes out of scope, the value will be dropped. According to rust-lang.org: Static items do not call drop at the end of the program. After reading this SO post, and given the code below, I understand that foo is a value whose variable y , equivalent to &y since "string literals are string slices", is called its owner . Is that correct? Or do static items

问题 I have been noticing that when I pull from my github repo on a development server(Red Hat) the ownership of the files change after the pull is completed. The .git file used to be owned by me but then I noticed that it would write files as me and I need it to write files as a different user. So i changed the ownership of the .git directory. I stumbled on to git config core.filemode which was true. I since have set to it false. I have not seen a difference after setting this to false. What

问题 I need a function or method in Python to find the owner of a file or directory. The function should be like: >>> find_owner("/home/somedir/somefile") owner3 回答1: I'm not really much of a python guy, but I was able to whip this up: from os import stat from pwd import getpwuid def find_owner(filename): return getpwuid(stat(filename).st_uid).pw_name 回答2: You want to use os.stat(): os.stat(path) Perform the equivalent of a stat() system call on the given path. (This function follows symlinks; to

问题 I'm reading Xcode's documentation, and here is something that puzzles me: __block typeof(self) tmpSelf = self; [self methodThatTakesABlock:^ { [tmpSelf doSomething]; }]; The following is copied from the documentation: A block forms a strong reference to variables it captures. If you use self within a block, the block forms a strong reference to self , so if self also has a strong reference to the block (which it typically does), a strong reference cycle results. To avoid the cycle, you need

问题 I'm developing a collaborative intranet site, and I've a problem with Google Apps Script in Google Site. When I develop, I am connected with my user account. But, all the scripts I write will execute under my account's context but I want that my scripts can access another account's context. For example, I've written a script that gives you the number of your unread mails in Gmail. But this script will always give the number of unread mails of the account that is the script's owner. You can
