Python: copying from clipboard using tkinter without displaying window

阅读更多关于 Python: copying from clipboard using tkinter without displaying window

问题 Running Python 3.4 on Windows 7. I need to copy what's stored in the clipboard to a variable in my python program. I've seen on Stack Overflow that that can be done either with pywin32 or tkinter. Since tkinter is part of the python standard library, I decided that that was the better of the two since the user won't have to install an external module. Here's the code for getting the clipboard data in tkinter: import tkinter number = tkinter.Tk().clipboard_get() This works fine except a blank

python3 ctype CreateWindowEx simple example

阅读更多关于 python3 ctype CreateWindowEx simple example

问题 I have googled for some time but could not find simple example of python3 ctypes and Win32 API for creating and showing window. Please point me to good link or show code here. Thanks in advance! 回答1: This is most easy to do with the win32gui module and its friends, win32api and win32con. There's no need to write your own ctypes wrappers to the Windows API. The simplest Petzold style app comes out something like this: import win32api, win32con, win32gui class MyWindow: def __init__(self):

How to catch printer event in python

阅读更多关于 How to catch printer event in python

I want to catch the signal when the printer started to print. That would be fine if you tell me how to get the path of document that will print. pywin32print looks like useful but I don't know how to use. To be notified of new print jobs, you can use FindFirstPrinterChangeNotification , FindNextPrinterChangeNotification , and a wait function from kernel32 such as WaitForSingleObject . Here's an example to set a filter that waits for a new print job on the local print server. There's much more work to be done if you want the JOB_NOTIFY_FIELD_DOCUMENT value out of a PRINTER_NOTIFY_INFO_DATA

问题 We're getting an Excel file from a client that has open protection and Write Reserve protection turned on. I want to remove the protection so I can open the Excel file with the python xlrd module.

what SendMessage to use to send keys directly to another window?

阅读更多关于 what SendMessage to use to send keys directly to another window?

问题 I'm trying to use SendMessage to send keyboard input to another window. I know the drawbacks, but I have to do it since I have to send several keys and I can't guarantee that the window will have focus - so this has to work when the window doesnt have focus. I'm testing it by trying to send keys to a notepad window. I've tried the following variations, and none have worked: def post_keys1(hwnd): win32api.SendMessage( hwnd, win32con.WM_KEYDOWN, ord('A'), 0 + (0 << 8) + (ord('A') << 16) + (0 <<
