VC creates a new process and ends the process (Open executable files such as exe)

In the VC program, how to end other processes that are running in the system (the process must have a window interface) is actually very simple, just follow the steps below:
1. Obtain the Process Handle (obtained using the findwindow function );
2. Get the process ID (obtained using the getwindowthreadprocessid function );
3. Open the process and set the first parameter in the OpenProcess function to process_terminate to obtain the handle to process the process;
4. Use the terminateprocess function to end the process and set the second parameter of the function to 4.

The Code is as follows:
// End the process
Int cstaticfunc: killprocess (lpcstr pszclassname, lpcstr

Pszwindowtitle)
{
Handle hprocesshandle;
Ulong nprocessid;
Hwnd thewindow;

Thewindow =: findwindow (null, pszwindowtitle );

/// Method 1:

: Getwindowthreadprocessid (thewindow, & nprocessid );
Hprocesshandle =: OpenProcess (process_terminate, false,

Nprocessid );
Return: terminateprocess (hprocesshandle, 4 );

/// Method 2:

Return: postmessage (thewindow, wm_close, null, null );

}

To start a process, you only need the CreateProcess function to complete the process. Note the input parameters of this function. The first parameter is

// Start a new process

/// Method 1:

Int cstaticfunc: createnewprocess (lpcstr pszexename)
{
Process_information piprocinfogps;
Startupinfo sistartupinfo;
Security_attributes saprocess, sathread;
Zeromemory (& sistartupinfo, sizeof (sistartupinfo ));
Sistartupinfo. cb = sizeof (sistartupinfo );
Saprocess. nlength = sizeof (saprocess );
Saprocess. lpsecuritydescriptor = NULL;
Saprocess. binherithandle = true;
Sathread. nlength = sizeof (sathread );
Sathread. lpsecuritydescriptor = NULL;
Sathread. binherithandle = true;
Return: CreateProcess (null, (lptstr) pszexename, & saprocess,

& Sathread, false,
Create_default_error_mode, null, null,

& Sistartupinfo, & piprocinfogps );
}

/// Method 2:

Winexec (Lpcmdline,Ucmdshow);
