句柄进程返回0

Question

我正在尝试读取进程句柄游戏，但如果我尝试读取进程句柄，它总是返回0，有人能给我解释一下吗

import ctypes, psutil
import sys

#DLLs needed
kernel32 = ctypes.windll.kernel32
#Process Permissions
PROCESS_QUERY_INFORMATION = (0x0400)
PROCESS_VM_OPERATION = (0x0008)
PROCESS_VM_READ = (0x0010)
PROCESS_VM_WRITE = (0x0020)

#Windows API's
OpenProcess = kernel32.OpenProcess
CloseHandle = kernel32.CloseHandle
GetLastError = kernel32.GetLastError
ReadProcessMemory = kernel32.ReadProcessMemory
WriteProcessMemory = kernel32.WriteProcessMemory
class ReadWriteMemory:

    def OpenProcess(self, myProcess):
        dwDesiredAccess = (PROCESS_QUERY_INFORMATION |
                           PROCESS_VM_OPERATION |
                           PROCESS_VM_READ | PROCESS_VM_WRITE);
        bInheritHandle = False
        for Process in psutil.process_iter():
            dfr = str(Process.name)
            i = dfr.find("name=")
            z = dfr.find(".exe',")
            if z == -1:
                z = i+8
            if dfr[i+6:z+4] == myProcess:
                dwProcessId = Process.pid
                hProcess = OpenProcess(
                    dwDesiredAccess,
                    bInheritHandle,
                    dwProcessId
                    );

                return hProcess
            elif Process.name == None:
                hProcess = None
    def CloseHandle(self, hProcess):
        CloseHandle(hObject);

    def GetLastError(self):
        GetLastError();
        return GetLastError()

    def PointerOffset(self, lpBaseAddress):
        pass


rwm = ReadWriteMemory()
handleProcess = rwm.OpenProcess('Empire Earth.exe')

print("handleProcess", handleProcess)

结果:

handleProcess 0

Answer 1

从^{} docs

If the function succeeds, the return value is an open handle to the specified process.

If the function fails, the return value is NULL. To get extended error information, call GetLastError.

这意味着在流程创建过程中出现了一些问题，您需要GetLastError提供更多细节
