permissions

问题 The possible values for SharedAccessBlobPermissions are: None (0) Read (1) Write (2) Delete (4) List (8) Add (16) Create (32) What are the differences between Add , Create and Write ? I can't find any documentation that clarifies this. 回答1: You can find information about these permissions here: https://msdn.microsoft.com/en-us/library/azure/dn140255.aspx.

问题 I previously had TFS 2017 and SQL 2016 working well on a single 250GB Server 2016 .VHDX with two partitions, C: and D: . SQL is installed on C: , with its data directories on D: . Oddly, C: started filling up unexpectedly, so I decided to move the D: partition to its own .VHDX and expand C: . This all went well, and I now have two 100GB .VHDXs with C: and D: , respectively. (This is a one-man shop, so data storage needs are quite small at present. These needs will increase soon, however, so

问题 I have a Python script that I wrote on my personal Windows computer. It's very, very basic and just shows a tkinter window with a couple labels. I compiled it into an .exe file using pyinstaller with the --onefile option. When I run that .exe file on that same computer, it all works just fine. If I copy the .exe file to a coworker's computer (also Windows), running it causes the command prompt to flash an error quickly. Opening the command prompt and executing it by typing the path, this is

问题 When you write some binary data in the http response stream (of Servlet etc) or using the Content-disposition header, what is the factor that determines whether the downloaded file is saved as readonly or has write permissions ? How can we control whether to make it read-only or not? Is that browser/OS dependant? 回答1: The only specified parameters for the Content-Disposition header field are filename , creation-date , modification-date , read-date , and size . You may use custom parameters

问题 I've noticed if you change the security settings for a particular directory, you can make that folder no longer "browsable" in windows. In particular, changing the "Read" permission for Administrators to "Deny" will make that folder inaccessible. The question I now have, is how do I figure this out in code? I following gets me close, but it still ain't right: /// <summary> /// Takes in a directory and determines if the current user has read access to it (doesn't work for network drives) ///

问题 I'm using cygwin on windows 7 to run a bash script that activates a python script, and I am getting the following error: myscript.script: /cydrive/c/users/mydrive/folder/myscript.py: usr/bin/env: bad interpreter: Permission Denied. I'm a total newbie to programming, so I've looked around a bit, and I think this means Python is mounted on a different directory that I don't have access to. However, based on what I found, I have tried to following things: Change something (from user to exec) in

问题 I need to let the user take a picture (from the gallery or from a camera app) with Android 6.0. Because I don't need to control the camera, I wanted to use an intent as describe here: However, if you don't need such control, you can just use an ACTION_IMAGE_CAPTURE intent to request an image. When you start the intent, the user is prompted to choose a camera app (if there isn't already a default camera app), and that app takes the picture. The camera app returns the picture to your app's

问题 I have IntentService task in foreground mode, but in Android M+ the task stops in Doze mode. I read Google banned if the app uses intent to set themselves in whitelist. But if I use permission and check GRANT or DENIED, I get the granted result, but nothing happen. I don't see my app in whitelist. How can I add the app in whitelist without banned? (I added permission in AndroidManifest.xml ) if(Build.VERSION.SDK_INT>=23){ int permissionCheck= ContextCompat .checkSelfPermission(this, Manifest
