Recently, the notebook has repeated several strange phenomena. After restarting, it enters the desktop, and then crashes. There is a blue screen.
Later, I checked the event in security mode, as shown below:

1. Introduction
In WMI, you can obtain information about a disk drive by using the Win32_Processor object:ManagementClass mc = new ManagementClass ("win32_cdromdrive");Managementobjectcollection MOC = MC. GetInstances ();foreach (ManagementObject mo in MOC){PropertyInfo = mo. Properties[propertyname]. Value.tostring ();}
2, Properties
The properties of the Win32_CDROMDrive object in WMI are as follows:

There is a good way to test whether a service has a response. First, using WMI to query the service you specify, WMI can return the ID that makes up its process.
function test-serviceresponding ($ServiceName)
{
$service = get-wmiobject-class win32_service-filter ' name= ' $ServiceName ' "
$processID = $service. ProcessID
$process = Get-process-id $processID $process
. Responding
}
Next, the p

Dim Uint32 as UInt32
For each cmicwmiobj as ManagementObject in Cmicwmi.get
Uint32 = cmicwmiobj ("signature")
Next
TextBox1.Text = uint32.tostring

Port Scan path:What is a scanner?A scanner automatically detects remote or local host security vulnerabilities.ProgramBy using a scanner, you can discover the distribution of various TCP ports on the remote server and the services provided and their software versions! This allows us to indirectly or intuitively understand the security problems of remote hosts.
Working PrincipleThe scanner collects a lot of useful information about the target host (f
The earlier interview was asked what the scanning use of the Zbar, and then asked why not the original, more efficient ah, saying that just started to achieve, do not seek efficiency, also do not know how to answer. Now in retrospect, the best answer is: Need to scan the album, the original implementation is not AH.Zbar Advantages: You can achieve photo scanning of albums But the efficiency is a little low.Native: High efficiency, but unable to do pho
When we are in the zxing framework to scan the QR code, we will find that now the mobile phone with the resolution of the addition.

1) Full Table scan (Full Table Scans, FTS)To scan the entire table, Oracle reads all rows in the table and checks whether each row meets the WHERE restrictions of the statement. Oracle reads each data block allocated to the table sequentially until it reads the highest waterline of the table (high water mark, HWM, marking the last data block of the table ). One multi-block read operation enables I/O to read

The index unique scan, which is a scan of a unique index, applies only to the target SQL that is the equivalent query in the WHERE condition. Because the scanned object is a unique index, the results of the index uniqueness scan will return at most one record.

After understanding it, ZBar is also a common QR code recognition software, the sdks for iOS and Android are provided for use. Finally, I chose ZBar for QR code identification. The annotations are clear and easy to use.ZBar provides two usage

The basic class is system. Management. managementquery, which represents the abstract management Query type and inherits icloneable. Managementquery is an abstract class. It has two important attributes: querylanguage and querystring (both string types), representing the query language and query string respectively. Although the managementquery type is an abstract class,
