i dont understand german at all but if your trying to make an "f5" clicker then here is a rough tut.
first create a new project then add a timer to your form
next set the interval of the timer to 330000 (thats 5.5 minutes)
next add a button to your your form and change the text to "Start" then double click it finally enter this code for your button:
PHP Code:
select case "Button1.text"
case "Start"
timer1.start()
button1.text = "Stop"
case "Stop"
timer1.stop
button1.text = "Start"
end select
and for you timer add this code to it(go back to your form and double click it if you havnt)
PHP Code:
Sendkeys.send("{f5}")
and you should have a "f5" clicker that sends the key f5 every 5.5 minutes
note: i didnt explain most of the steps like creating projects or adding controls...you learn that yourself if you dont already know
