What exactly do you want to do ?
The sw1_ValueChanged event routine is called when you click on the switch and Value returns the switch state.
If the switch is 'ON' Value = True.
If the switch is 'OFF' Value = False.
It's similar to the CheckBox in B4A.
in an pane ia have a switch, if is true when i click on a button go to sub a if switch is false go to sub b ....
but the switch not work in this mode it's every false (the default state)
I don't understand how it work.
This is the view , when i click on button in right bottom, if the switch is on go to 'sub a' if it off go to 'sub b'.
But if i set switch on, when i click the button the value is always off ....
What happens when you click on the Switch ?
Does it change or not.
Otherwise post your project (IDE menu File / Export As Zip) so we can see what you have done and how.
When you zip a project you should do it in the IDE menu File / Export As Zip, as already suggested in post #6.
This way all relevant files are included.
In such cases it might be interesting to make a smaller project showing the problem.
And sometimes, the small one works OK and allows to find the problem (personal experience).
