How to press the Windows key programmatically using C# SendKeys

I want to know the sendkey for windows key (that key in keyboard with windows Flag on it)
I don't think you can easely call the windows flag key. You will need to p/invoke an API function instead, I think it was keybd_event to send the Windows key.

Can I SendKeys to a selected window in c#?
The Program knows the window which it has to send it and the window not really necessary to be the active window.
I just want to give the program window name and send into it.
EX : I type application name (notepad for example) and not really necessary to be focused Upon the meant window.

How can I simulate function key combinations using C#?

So, I've created an on screen keyboard which is working great - except on my current keyboard I press FN and F1 (for example) and my screen brightness increases. F2 decreases, F5 turns backlit keyboard on/off etc etc
Can I recreate this on my keyboard? I thought maybe there would be someway of seeing how it works currently and adding that to my code? But I'm just a beginner so I don't really know.
I don't imagine there is a SendKeys parameter to handle this, so is there a work around?
Cheers!
The FN key modifies the key code being sent. So to do this (since the FN key acts as a hardware modifier as opposed to ALT, SHIFT, etc.) you could create a MessageBox that displays the key code whenever you press a key and use the values it gives you with these codes

Capture keyboard inputs without a textbox
(1 answer)
Closed 7 years ago.
I'm working on an university project of a windows forms calculator with c#.
Is fully functional, but the question is.
Can I insert numbers in the main textBox without focusing on it. I want it to work like windows calculator and insert numbers without having to click the textbox.
I've try a lot of methods like using the event Key_Press directly on the form but nothing works.
Ps. Is like windows calculator.
Set the Form.KeyPreview property to true and handle the Form_KeyPress event.

Is it possible to detect when a PC is logging off. I need to develop an application which writes in a text document about the logoff time, before the PC gets logged off.
