这样做的方法是调用Windows
ShellExecuteEx() API传递属性动词.有各种高级Python包装器,但我没有成功地使用属性动词.相反,我会使用好老的ctypes.
import time
import ctypes
import ctypes.wintypes
SEE_MASK_NOCLOSEPROCESS = 0x00000040
SEE_MASK_INVOKEIDLIST = 0x0000000C
class SHELLEXECUTEINFO(ctypes.Structure):
_fields_ = (
("cbSize",ctypes.wintypes.DWORD),
("fMask",ctypes.c_ulong),
("hwnd",ctypes.wintypes.HANDLE),
("lpVerb",ctypes.c_char_p),
("lpFile",ctypes.c_char_p),
("lpParameters",ctypes.c_char_p),
("lpDirectory",ctypes.c_char_p),
("nShow",ctypes.c_int),
("hInstApp",ctypes.wintypes.HINSTANCE),
("lpIDList",ctypes.c_void_p),
("lpClass",ctypes.c_char_p),
("hKeyClass",ctypes.wintypes.HKEY),
("dwHotKey",ctypes.wintypes.DWORD),
("hIconOrMonitor",ctypes.wintypes.HANDLE),
("hProcess",ctypes.wintypes.HANDLE),
)
ShellExecuteEx = ctypes.windll.shell32.ShellExecuteEx
ShellExecuteEx.restype = ctypes.wintypes.BOOL
sei = SHELLEXECUTEINFO()
sei.cbSize = ctypes.sizeof(sei)
sei.fMask = SEE_MASK_NOCLOSEPROCESS | SEE_MASK_INVOKEIDLIST
sei.lpVerb = "properties"
sei.lpFile = "C:\\Desktop\\test.txt"
sei.nShow = 1
ShellExecuteEx(ctypes.byref(sei))
time.sleep(5)
我调用sleep的原因是属性对话框在调用进程中显示为一个窗口.如果Python可执行文件在调用ShellExecuteEx之后立即终止,则没有任何内容可以为对话框提供服务而且它不会显示.
