CFindKillProcess
Readersmay often encounter such a problem ,think to some operation ,found the file is being used by other programs ,in an open state ,and is exclusive to open ,then is not operation file .
Therefore ,in order to operate these files ,open the file the process must be removed .How to clean the scavenging process ?In fact ,in the Windows2000 operating system version has a program called tskill.
exe ,it can be used to clear out a process in ,abercrombie france,enter program name after you can clear the running example .But how to code in tskill realize the function of the how to do ?Aiming at this problem ,the example introduced in the Windows2000 realizing method .
One ,the realization method in Visual C++ programming, most secure kill process method is to run the program to send the WM_CLOSE message ,the code is as follows :HWND hWnd =this.m_hWnd ;/ / get the main window PostMessage ( hWnd ,WM_CLOSE ,0 ,abercrombie,0) ;send this message, usually should wait until the process is terminated ,when the process terminates ,it sends status signals ,and WaitForSingleObject returned WAIT_OBJECT_0 .
If the return of other values ,process or hang out ,either still in processing .In this case ,kill the process is the only way to use the more powerful API function :TerminateProcess ( ) .
If you want to do a bit more beautiful ,can be in a closed prior to the main window to send a WM_QUERYENDSESSION message ,when the user end session ( log out ) or call ExitWindows ( ) function, the application will receive this message, then prepare to withdraw from the process ,abercrombie france,the general will pop up a dialog box ,telling the user : program to rolled out ,if you want to save changes things ,now is the best time ,want to save ? There are three to choose ( Yes/No/Cancel ) .
In addition ,sending the WM_QUERYENDSESSION message can refuse to launch process ( press the Cancel ) ,and if so ,www.monclerfrancesmagasin5s.com,the process will continue .If you want to close the process is suspended ,the use of SendMessageTimeout ( ) function is very important ,but not with SendMessage ( ) function ,the parameter SMTO_NOTIMEOUTIFNOTHUNG is one of only 2000 and Windows Windows XP only sign .
Its meaning is if the thread does not hang ,not time-out ,in other words if the thread is normally processing ,then wait forever ,so the user can see the dialog and decide what to do ,when the user finally made the decision after SendMessageTimeout ( ) ,with the corresponding bOKToKill value return .
In this case in order to improve the reusability of the code ,the implementation details are encapsulated in a CFindKillProcess class, including search and kill the process ,please see EnumProc.
h and EnumProc.cpp files .File another two reusable classes ,one is CProcessIterator ,another is CWindowIterator .This in practice acquisition process of the main window and the process of creating the program name has been described in detail .
The CfindKillProcess member function of class FindProcess ( ) a search into the program ,if you find this process ,it returns the process ID ,then the ID to CFindKillProcess: :KillProcess ( ) function ,KillProcess ( ) function encapsulates the closed window and termination logic ,jordan,it uses the CmainWindowIterator class object to enumerate the process of the main window ( may be more than one ,see obtain a process of the main window and the process of creating the program name ? ) ,and send WM_CLOSE to every window ,and then wait for the process to death .
It has a Boolean parameter is used to indicate when an application process to quit when whether to execute the TerminateProcess ( ) function ,www.abercrombiefrancele.com.For details please see download code .Two ,1 ,Visual C++6.
