问题
3G module in a notebook. When I restart that notebook, the 3G module is turned off again. I have to turn it on on every restart.
So that's why I thought I need a simple software that simulates the KeyEvent of Fn+-. It's function on the notebook keyboard is to en- or disable th 3G-module.
An option would be that I find out the 3G module's hardware-ID and activate it. (Apparently it uses 1 network device and 4 COM-ports in the device manager...)
I already discovered Google and found these threads:
- Simulating Keyboard with SendInput API in DirectInput applications
- How can I simulate function key combinations using C#?
Unfortunately these threads don't give me a solution...
Now my question: What method would be more simple?
- simulating the Fn-KeyPress
- getting the hardware-IDs and acitvating them
And then... how to solve that problem in an easy way?
I hope the given Information will help you to help me. :)
Additional info: the solution may be in C#, BATCH or even registry "hacks". I just want that 3G module to be turned on!
//EDIT: Playing with the hardware-ID will NOT work! After a restart, it's simply not in the device manager. Only after I once activated Fn+- it's listed there. So is there any other way to just switch on 3G?
回答1:
To simulate a keyboard event you should be able to create a new keyboard event which will simulate a keypress in C#. example
keybd_event( VK_NUMLOCK,0x45,KEYEVENTF_EXTENDEDKEY | 0, 0 );
