How to access the Windows global file lock table in .Net?


How to access the Windows global file lock table in .Net?

I think the issue was by ths following , No, it is stored in ring 0 code. Kernel code, only a device driver can get to it. The kind that dynamically gets installed by, for example, SysInternals' Handle utility. Whose author also reverse-engineered the undocumented kernel structures to find that table and is willing to maintain that code for all previous and future Windows versions. Hopefully.
This is quite intentionally out of reach from user-mode code. Nothing ever good happens when programs try to get that kind of information. Like your plan, checking if a file is locked. That simply cannot work reliably on a multitasking operating system.

With these it helps Using portalocker we can lock a file for access through the following way: , You could use subprocess to open the file in notepad or excel:
code :
import subprocess, time

subprocess.call('start excel.exe "\lockThisFile.txt\"', shell = True)

time.sleep(10) # if you need the file locked before executing the next commands, you may need to sleep it for a few seconds
subprocess.call('notepad > lockThisFile.txt', shell = True)
subprocess.call('taskkill /f /im notepad.exe') # or excel.exe

like below fixes the issue ~/.java/.userPrefs directory, one of its subdirectories or the individual file has wrong permissions so that JVM is not able to write there.
This can occur if you've started some Java app from a different user (such as root) and the directory was created with the permissions for that user.

will help you The first difference to understand is the difference between the Card Life Cycle States and Application and Security Domain Life Cycle.
The Card Lock Privilege is used to change the Card life Cycle to Locked state and either the OPEN, or a Security Domain with Card Lock privilege, or an Application with Card Lock privilege , may initiate the transition from the state SECURED to the state CARD_LOCKED.
