Is not the same process, are two different processes, a process to monitor the news of another process

CodePudding user response:

Then try SetWindowsHookEx WH_CALLWNDPROC

CodePudding user response:

Void CMyDlg: : OnButton1 ()
{
//TODO: Add your the control notification handler code here
HWND WND=: : FindWindow (" NotePad ", 0);//"no title - notepad");
: : SendMessage (WND, WM_SYSCOMMAND, SC_CLOSE, 0);
}

{
//TODO: Add your the control notification handler code here
HWND WND=: : FindWindow (" NotePad ", 0);//"no title - notepad");
: : SendMessage (WND, WM_SYSCOMMAND, SC_CLOSE, 0);
}

Tried, with the above way to shut down, will cause the program can't start,

- want to listen the the process of news, but I don't know whether using hook can solve

CodePudding user response:

Will cause the program can't start?

Custom encapsulates the message, not the so-called
