using ctypes I get the error: 'module' object has no attribute 'WinDLL'

Asked by GZ

Hi Everyone,

To check num lock state (and deactivate if necessary to overcome the shift key bug), I do the following in python:

import ctypest
ctypes.WinDLL("User32.dll").GetKeyState(0x90)

This works in python but in Sikuli I get the following error:
[error] AttributeError ( 'module' object has no attribute 'WinDLL' )

Is there a solution or alternative to this?

Thanks,
George

the ctypes module cannot be loaded in Jython environment.
Only modules that are completely written in Python language and do not have any native C/C++ libraries.

I do not have an easy solution for this.

You have to look out for a Jython or Java library that does what you want.
Other options are JNI and/or JNA.

I use the library bridj in SikuliX to issue a few Windows API calls for the system path handling.
(example: see org.sikuli.util.SysJNA.java)

Ahh I see :(

I would use it to check the num-lock state and if it is 1, I would run type(Key.NUM_LOCK) to disable it and then I can use KEY_SHIFT (to overcome this bug where I can't use shift + combo if numlock is on).

Is there any good way of doing that then?

use SikuliX features:
http://sikulix-2014.readthedocs.org/en/latest/globals.html#get-information-about-the-runtime-environment
(isLockOn)

... and then appropriate type()
