问题 I'm trying to read the access for files and directories in Windows using this code (patterned after Tim Golden's proposed patch to os.access to make it read from ACLs on Windows): from ctypes import( windll, wintypes, c_char_p, c_void_p, byref ) from win32api import GetCurrentThread from win32security import ( GetFileSecurity, DACL_SECURITY_INFORMATION, ImpersonateSelf, SecurityImpersonation, OpenThreadToken, TOKEN_ALL_ACCESS, MapGenericMask ) from ntsecuritycon import ( FILE_READ_DATA, FILE

问题 I have a Python script that works perfectly fine on my development PC. Both are Windows 7 with the same Python version (2.7.9). However on the target machine I get a ValueError: can't format dates this early The error seems to come from pywin32 module. The code uses a third-party library invoked by pywin32: raw = win32com.client.Dispatch("MyLib.MyClass") and then fails later on: acq_time = raw.GetCreationDate() Now I'm lost why this is working on my PC and not on the target machine. Both have

问题 I have measured the performance of psutil.Process(pid).name and it turns out that it is more than ten times slower than for example psutil.Process(pid).exe . Because the last one of these functions requires different privileges over the path, I cannot just just extract the filename from the path. My question is: Are there any alternatives to psutil.Process(pid).name , which does the same? 回答1: You mentioned this is for windows. I took a look at what psutil does for windows. It looks like

问题 I am currently trying to write a large amount of data to an excel spreadsheet using the pywin32 libraries. As a simple example of the problem that I am facing take the following code to generate a 1000 cell x 1000 cell multiplication table. import win32com.client from win32com.client import constants as c xl = win32com.client.gencache.EnsureDispatch("Excel.Application") xl.Visible = True Workbook = xl.Workbooks.Add() Sheets = Workbook.Sheets tableSize = 1000 for i in range(tableSize): for j

问题 while my script is updating one excel same time if i am going to do any other work manually with another excel error occurs i am using dispatch from win32com.client import Dispatch excel = Dispatch('Excel.Application') excel.Visible = True file_name="file_name.xls" workbook = excel.Workbooks.Open(file_name) workBook = excel.ActiveWorkbook sheet=workbook.Sheets(sheetno) I am geting error like this (, com_error(-2147418111, 'Call was rejected by callee.', None, None) Is there is any way to

问题 I've added code to a Python package (brian2) that places an exclusive lock on a file to prevent a race condition. However, because this code includes calls to fcntl , it does not work on Windows. Is there a way for me to place exclusive locks on files in Windows without installing a new package, like pywin32 ? (I don't want to add a dependency to brian2 .) 回答1: Since msvcrt is part of the standard library, I assume you have it. The msvcrt (MicroSoft Visual C Run Time) module only implements a

问题 I have a little Tkinter application here, as well as a handle to the Tkinter window. What I'm trying to do is remove the window from the taskbar using some combination of Windows API calls. Basically I don't want the window to show up in the task bar. import Tkinter as tk import string import win32ui import win32con root = tk.Tk() handle = string.atoi(root.wm_frame(), 0) winhandle = win32ui.CreateWindowFromHandle(handle) root.mainloop() 回答1: I hope this helps, or at least guides you somehow.

问题 For a long time I tried to use the LVM_GETITEMW message with LVIF_TEXT mask to get the text of a ListView. My program worked in 32 bit but not in 64 bit architecture. I discovered that the problem was at the LVITEM struct. Shortly, my question is which struct is the appropriate one for 64 bit and why. The struct I used as the LVITEMW struct had the following fields: ('mask', c_uint32), ('iItem', c_int32), ('iSubItem', c_int32), ('state', c_uint32), ('stateMask', c_uint32), ('pszText', c
