How to programmatically enable/disable network interfaces? (Windows XP)
I need to enable/disable completely network interfaces from a script in Windows XP. I'm looking for a python solution, but any general way (eg WMI, some command-line à la netsh, some windows call) is welcome and will be adjusted. Thanks.

Using the netsh interface Usage set interface [name = ] IfName [ [admin = ] ENABLED|DISABLED [connect = ] CONNECTED|DISCONNECTED [newname = ] NewName ]
Try including everything inside the outer brackets: netsh interface set interface name="thename" admin=disabled connect=DISCONNECTED newname="thename"
See also this MS KB page: http://support.microsoft.com/kb/262265/ You could follow either of their suggestions. For disabling the adapter, you will need to determine a way to reference the hardware device. If there will not be multiple adapters with the same name on the computer, you could possibly go off of the Description for the interface (or PCI ID works well). After that, using devcon (disable|enable). Devcon is an add-on console interface for the Device Manager.Answered by: Chloe970 | Posted: 02-11-2021
So far I've found the following Python solution:
>>> import wmi; c=wmi.WMI() >>> o=c.query("select * from Win32_NetworkAdapter where NetConnectionID='wifi'") >>> o.EnableDevice(1) (-2147217407,)
which is translated, AFAIU, to the generic WMI error 0x80041001. Could be permissions.Answered by: Richard139 | Posted: 02-11-2021
I found this .VBS script on the internet. It has the cool advantage of actually working on machines where I cannot get NETSH to work for this purpose.

I can't seem to find any basic API for controlling interfaces on MSDN, apart from the RAS API's, but I don't think they apply to non-dialup connections. As you suggest yourself, netsh might be an option, supposedly it also has a programmatic interface: http://msdn.microsoft.com/en-us/library/ms708353(VS.85).aspx
If you want to be pure Python, you can perhaps open a set of pipes to communicate with an netsh process.Answered by: Audrey426 | Posted: 02-11-2021
this is VB.Net
Dim objectQuery As New ObjectQuery("SELECT * FROM Win32_NetworkAdapter WHERE NetConnectionId IS NOT NULL") Dim searcher As New ManagementObjectSearcher(scope, objectQuery) Dim os As ManagementObject Dim moColl As ManagementObjectCollection = searcher.Get() Dim _list As String = "" For Each os In moColl Console.WriteLine(os("NetConnectionId")) Next os
That will get all the interfaces on you computer. Then you can do netsh to disable it.

netsh interface set interface DISABLED
The devcon tool can control the NIC, but not the interface directly. It's a command-line version of the Device Manager applet.

devcon disable (id or portion of name) devcon enable (id or portion of name)
You may need to use WMI. This may serve as a good starting point: http://msdn.microsoft.com/en-us/library/aa394595.aspxAnswered by: Carlos660 | Posted: 02-11-2021

How can I override this behavior and allow my users to sort the custom folders manually, say through the ...

python - Scrolling QGraphicsView programmatically
I've want to implement a scroll/pan-feature on a QGraphicsView in my (Py)Qt application. It's supposed to work like this: The user presses the middle mouse button, and the view scrolls as the user moves the mouse (this is quite a common feature). I tried using the scroll() method inherited from QWidget. However, this somehow moves the view instead - scrollbars and all. See picture. So, given that this is not the wa...
