The way to do this is to call the Windows ShellExecuteEx()
API passing the properties
verb. There are various high-level Python wrappers of this but I have not succeeded in getting any of them to work with the properties
verb. Instead I would use good old 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)
The reason I put in the call to sleep
is that the properties dialog is shown as a window in the calling process. If the Python executable terminates immediately following the call to ShellExecuteEx
, then there is nothing there to service the dialog and it does not show.
