I have read a lot of docs and articles and posts all over the internet. Almost everyone and everywhere commits that SpinLock is faster for a short running pieces of code, but I made a test, and it appears to me that simple Monitor.Enter works faster than SpinLock.Enter (Test is compiled against .NET 4.5) using System; using System.Collections.Concurrent; using System.Collections.Generic; using System.Diagnostics; using System.Threading.Tasks; using System.Linq; using System.Globalization; using System.ComponentModel; using System.Threading; using System.Net.Sockets; using System.Net; class

Monitor Process in Python?

问题 I think this is a pretty basic question, but here it is anyway. I need to write a python script that checks to make sure a process, say notepad.exe, is running. If the process is running, do nothing. If it is not, start it. How would this be done. I am using Python 2.6 on Windows XP 回答1: There are a couple of options, 1: the more crude but obvious would be to do some text processing against: os.popen('tasklist').read() 2: A more involved option would be to use pywin32 and research the win32

Visual Studio and dual/multiple monitors: how do I get optimized use out of my monitors? [closed]

Ultramon is a great program for dual monitors (stretching screen across monitors), but I was wondering if there is any way do to something in Visual Studio like have one tab of code open on one monitor and a second tab of code open on the second monitor with only one instance of Visual Studio running? Or are there any other suggestions on getting most bang for buck on dual monitors and Visual Studio? Personally, I have my windows set up so that one my main monitor, I have the main visual studio monitor, so therefore my code window, maximized, with only the toolbox docked, on the left. This

How to monitor just t-sql commands in SQL Profiler?

主宰稳场 提交于 2019-11-29 13:42:57
I have a trouble in monitoring t-sql commands, I want to monitor just commands like: select, insert, update or delete. Can anyone help me? Pick a trace template (such as Tuning) and use a filter. Either filter by a particular login (such as your own login or a service's login), a particular database. For instance, to filter by database: Under Trace properties -> Events tab -> Select show all columns. Set a Like filter on database name. I find setting a filter on the number of Logical Reads of say > 10 reads, filters out most of the noise. How to: Filter Events in a Trace Using SQL Server

Monitor battery charge with Win32 API

随声附和 提交于 2019-11-29 10:40:29
I'm trying to write a small app that monitors how much power is left in a notebook battery and I'd like to know which Win32 function I could use to accomplish that. For Vista and up you can use RegisterPowerSettingNotification For earlier functions see the Power Management Functions in this section of the MSDN page "Power Management Functions: Windows Server 2003 and Earlier" You can see example code of the Vista method on codeproject . I recommend the use of the Win32 GetSystemPowerStatus function. A code snippet : int getBatteryLevel() { SYSTEM_POWER_STATUS status; GetSystemPowerStatus(

How do I wake up my Windows monitors once turned off by power settings?

社会主义新天地 提交于 2019-11-29 08:16:55
So my Vista machine is set to turn off it's monitors after 10 minutes. (Note : machine is not suspended, or hibernated) I have a .Net application running, that needs to "wake" the system at a specified time. As a human, you just move the mouse or press a key. How do I do this programatically? I've tried : programatically setting the cursor; using "SendKeys"; and even pinvoking CreateWaitableTimer to unsuspend (even though it's not suspended) in the hope that that would trigger something. Ideally code in c# would be great, but the correct Win API would suffice. Many thanks in advance. You

Monitoring the progress of an SQL query in SQL SERVER

∥☆過路亽.° 提交于 2019-11-29 05:36:22
I saw a similar question which asked how to monitor the progress of a backup/restore operation: Is there a SQL script that I can use to determine the progress of a SQL Server backup or restore process? I would like to know if there's a similar query/way to see how much time the query has left until it will end. For example, one query usually has an elapsed time of 5 minutes. I would like to know how much time is left until it will end DURING the query's execution. KM. There is no way to know how much time is left. A query's runtime depends on many things beyond the actual query itself: locking
