Title: Global hotkey
Post by: authorleon on March 08, 2018, 01:15:37 PM

Hello,

I have a very simple form which uses a few buttons to directly control the outputs on an SLC500.

I have a piece of code which allows you to have hotkeys but only when you are focused on the form.

Is there a simple way to have global hotkeys. i.e. CTRL + ALT + SHIFT + U (Mover motor up).

I have been trying for the last six months on and off but unfortunately no success.

Is it possible to have a piece of code that emulates pressing the button.

I can get one working but you have to be focused on the form...

Can anyone really help me with this???

Hello,

Thank you very much for the information.

I have had a look at the links and I do have the global hotkeys. But I have a problem maybe somebody can help you with.

I am using the buttons in the application.

So when I press the button. It activates the appropriate output.
When I release the button, it deactivates that same output.

So physically pressing the buttons works perfectly.

I am using the buttons not as a toggle. When you press and hold the button the output stays on. When you release the button it turns off.

I cannot find any release function at all in VB.

Does anyone know of a special trick, hack or whatever to get this working.

I am willing to pay as well, if only I could have just a piece of code and then I can integrated.

I really appreciated and I really need to find a solution. Thank you very much

Just use the MouseUp event.


Private Sub BasicButton1_MouseUp(sender As Object, e As MouseEventArgs) Handles BasicButton1.MouseUp

'Put your code here'

End Sub
