ctypes CreateProcessWithLogonW执行后Python进程失败

Question

我尝试在另一个用户下执行python脚本（通过python进程）。我在网上找到了这段代码的一部分，运行得很好；除了一件事。在

当进程终止时，python将失败。在

所以说清楚，不同用户下的第二个python进程使用CreateProcessWithLogonW执行得很好，但是第一个脚本失败了（我想）。在

我的想法可能是错误的，我的代码使用可能是错误的。。。在

一个python进程会导致什么反应迟钝？在

我试过很多东西（例如系统出口（0）以明确任务已完成…，但无法获取。在

我在win7上运行python2.64bit

Answer 1

句柄是64位系统上的64位整数类型。尝试“从”ctypes.wintypes“导入句柄”而不是“句柄=DWORD”

Answer 2

检查lpApplicationName和lpCommandLine的参数；解决方法之一是为前者传递NULL，为后者传递完整的命令行：

p = CreateProcessWithLogonW('user',
                            'domain',
                            'password',
                            0,
                            NULL,
                            r'C:\Python26\python.exe C:\mySimpleScript.py')
