Kill process started with ShellExecuteEx

1) I started a process with ShellExecuteEx

2) retrieve the PID with 

GetProcessId(shellExInfo.hProcess)

Sample Code:

SHELLEXECUTEINFO shellExInfo;

shellExInfo.cbSize = sizeof(SHELLEXECUTEINFO);
shellExInfo.fMask = SEE_MASK_NOCLOSEPROCESS;
shellExInfo.hwnd = NULL;
shellExInfo.lpVerb = "open";
shellExInfo.lpFile = processToStart.c_str();
shellExInfo.lpParameters = processParams.c_str();
shellExInfo.lpDirectory = NULL;
shellExInfo.nShow = SW_SHOW;
shellExInfo.hInstApp = NULL;

ShellExecuteEx(&shellExInfo); // start process

GetProcessId(shellExInfo.hProcess); // retrieve PID

Now I want to kill the started process with given PID! How is this possible?

Thx

To terminate a process you have to use the TerminateProcess function. However, it receives a handle to the process as a parameter:

TerminateProcess(shellExInfo.hProcess, 1);

If for some reason you store only the process id but not the handle, then you should open a handle first using the OpenProcess function:

HANDLE h = OpenProcess(PROCESS_TERMINATE, false, process_id);
TerminateProcess(h, 1);
CloseHandle(h);
