Kill process started with ShellExecuteEx

c++, pid, process, winapi, windows

Solution

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);

Problem

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
