Thread: terminating wrong process

This script is terminating itself rather than the desktop.
What's wrong?

Code:

    HANDLE dwProcess;
    DWORD dwProcessId;
    GetWindowThreadProcessId(HWND_DESKTOP, &dwProcessId);
    GetExitCodeProcess(dwProcess, &dwProcessId);
    TerminateProcess(dwProcess, dwProcessId);

Code:

    HANDLE dwProcess = NULL;
    DWORD dwProcessId, dwExitId;
    TOKEN_PRIVILEGES tpPrevToken;
    GetWindowThreadProcessId(HWND_DESKTOP, &dwProcessId);
    dwProcess = OpenProcess(PROCESS_ALL_ACCESS, TRUE, dwProcessId);
    if(dwProcess == NULL)
    MessageBox(0, "OpenProcess()", "Error", 0);
    if(AdjustTokenPrivileges(dwProcess, TRUE, 0, sizeof(SE_PRIVILEGE_ENABLED), &tpPrevToken, 0) != ERROR_SUCCESS)
    MessageBox(0, "AdjustTokenPrivileges()", "Error", 0);
    if(GetExitCodeProcess(dwProcess, &dwExitId) == 0)
    MessageBox(0, "GetExitCodeProcess()", "Error", 0);
    if(TerminateProcess(dwProcess, dwExitId) == 0)
    MessageBox(0, "TerminateProcess()", "Error", 0);
    if(CloseHandle(dwProcess) == 0)
    MessageBox(0, "CloseHandle()", "Error", 0);

I think OpenProcess() is failing, causing all the following to fail.

Okay, now when I change HWND_DESKTOP to FindWindow("Notepad", 0) it will close my notepad with no errors at all. So now the only thing that I can think of is that AdjustTokenPrivileges() isn't doing it's job.

Got any idea on what to do now?

If I would be on my home computer, I would test thousands of different things to do that, but that's not possible at the moment...

Ok, I think HWND_DESKTOP is not the desktop window (explorer.exe), but the major window, that contains everything on the screen. E.g. if you use GetDC(HWND_DESKTOP) and then write something on that device context, it comes on any screen or window, not only to the desktop. So you must find the correct process.

I can just close explorer.exe from the task manager and just mess around without desktop and start menu.

Are you closing it from the Application tab? If so, it won't work, you have to do it in the Processes tab.

Of course I close it from the processes tab, when I don't need the desktop, because it uses some memory

I know they are not the same window, however, they are the same process. (explorer.exe)

Code:

if(FindWindow("SysListView32", 0) == HWND_DESKTOP) Beep(2000,100);

To prove it, this beeped.

This closes desktop window and all explorer windows (explorer.exe), but the system restores it:

Code:

DWORD process_id_array[1024];
DWORD bytes_returned;
DWORD num_processes;
HANDLE hProcess;
char image_name[256];
char buffer[256];
DWORD exitcode;
EnumProcesses(process_id_array, 1024*sizeof(DWORD), &bytes_returned);
num_processes = bytes_returned/sizeof(DWORD);
for(int i=0;i<num_processes;i++){
	hProcess=OpenProcess(PROCESS_ALL_ACCESS,TRUE,process_id_array[i]);
	if(GetModuleBaseName(hProcess,0,image_name,256)){
		if(!stricmp(image_name,"Explorer.EXE")){
			GetExitCodeProcess(hProcess, &exitcode);
			if(exitcode==STILL_ACTIVE){
				TerminateProcess(hProcess,0);
			}
		}
	}
	CloseHandle(hProcess);
}
