Terminate an application...!

Hello ALL.,
How do I termintate an application(say.."Media Player") which is opened using CreateProcess(...) ?

Thanks in advance...!

Have you tried sending WM_QUIT to it using PostMessage()?

Thanks a million Hobbieman for your quick response..

Would you please write me a small example.?

I already mentioned that e.g; Media player is opened using CreateProcess(..) and I would like to terminate MediaPlayer.

Hi


Do a FindWindow to that Media player.

it will give you CWnd,after that send a message to that Wnd with WM_QUIT.

Hope this helps

Regards

Available in the MSDN with sample code that you can easily take
out and change for your needs.
HOWTO: Terminate an Application "Cleanly" in Win32 Q178893

Thanks Spicy Kids ..for your reply..

Well.., partially u are correct..
But, in case there more than 1 Media Player opened... (One is manually & other is from my program using CreateProcess(..) )then according to you, it will close all the Media players.. Right.?

But, I would like to close the only Media Player opened by my program using CreateProcess...

any hint.?

When you create a process with CreateProcess(), it returns
the Process ID of the created process in the
"Process Information" structire. You can use
that to distinguish between multiple instances
of the Media Player.

I open the application like the following code :

Code:

---

STARTUPINFO si;
        ::ZeroMemory(&si,sizeof(STARTUPINFO));
        si.cb = sizeof(STARTUPINFO);
        PROCESS_INFORMATION pi;   
        ::ZeroMemory(&si,sizeof(STARTUPINFO));
        si.cb = sizeof(STARTUPINFO);
       
        if(bVolFlag == FALSE){
               

        if(CreateProcess(NULL,"D:\Program Files\\Windows Media Player\\wmplayer.exe" , NULL,
                                NULL,FALSE,NORMAL_PRIORITY_CLASS,NULL,NULL,&si,&pi))
        {
                //        ::CloseHandle(pi.hThread);
                //        ::CloseHandle(pi.hProcess);
        }

---

Closing here ...

Code:

---

PostThreadMessage(pi.dwThreadId, WM_CLOSE, 0, 0);

---

It doesn't work..

I also tried with the code given HERE referred by mdmd ..(Thanks to him)..

But, failed...

Plz , help me out..

Are you using the process ID or the thread ID with the articles
code ? I'm using your CreateProcess code, with a different
windows media exe name, and the articles code without
modification. It closes the media player OK.

Code:

---

if(CreateProcess( "C:\\Program Files\\Windows Media Player\\mplayer2.exe",NULL , NULL,NULL,FALSE,NORMAL_PRIORITY_CLASS,NULL,NULL,&si,&pi))
        {
                //        ::CloseHandle(pi.hThread);
                //        ::CloseHandle(pi.hProcess);
        }

TerminateApp( pi.dwProcessId , 1000 );

---

Here is one suggestion, which should work:

Since you have the process ID (in pi.dwProcessID)
use that to call OpenProcess(), which will give you
a handle to your process.

Next, call TerminateProcess() giving it the handle to the
process, which should terminate it.

A bit drastic, but it will work.

Thanks a Million Kochhar for your suggestions...

Here is the code I already tried...

Code:

---

#define TA_FAILED 0
#define TA_SUCCESS_CLEAN 1
#define TA_SUCCESS_KILL 2
#define TA_SUCCESS_16 3

DWORD CGlobalTestDlg::TerminateApp(DWORD dwPID, DWORD dwTimeout)
{
       
          HANDLE  hProc ;
      DWORD  dwRet ;

      // If we can't open the process with PROCESS_TERMINATE rights,
      // then we give up immediately.
      hProc = OpenProcess(SYNCHRONIZE|PROCESS_TERMINATE, FALSE,
        dwPID);

      if(hProc == NULL)
      {
        return TA_FAILED ;
      }
      // Wait on the handle. If it signals, great. If it times out,
      // then you kill it.
      if(WaitForSingleObject(hProc, dwTimeout)!=WAIT_OBJECT_0)
        dwRet=(TerminateProcess(hProc,0)?TA_SUCCESS_KILL:TA_FAILED);
      else
        dwRet = TA_SUCCESS_CLEAN ;

      CloseHandle(hProc) ;

      return dwRet ;

}

---

But, no success..:( hProc is NULL here..where do I go wrong..?

Why did you remove this line ? If you use the unmodified code
it should close all the windows and terminate the process of the
WMPLAYER process id that you pass to TerminateApp

Code:

---

EnumWindows((WNDENUMPROC)TerminateAppEnum, (LPARAM) dwPID) ;

---

Thanks mdmd.. & everone for your patience..

Unmodified code works fine...:)
