key down event to start something an stop arbirtrary

[prkm]

hallo,

what I'm trying to do is to start an event on key down an do a loop , something like move an axis for CNC , and this until i press an arbitrary key again.

i have already a while loop an an event structure so it would be good just to add something withtout large modifications.

have anyone an example code for me , please.

i've looked already in a lots of posts but i can't find anything usefull for me.

many thanks in advance

Use the event for <vi> Key Down.  Check to see which key was pressed, then create a case to handle the appropiate keys.

thank you but it just say a or not a ,what i want is a loop in this event which which will be executed till the next key is pressed so it ist unknown how many times this loop will be executet. i dont know how to handle this.

i can do what i want just 1 time and then i have to press again a key , but it should run until a key is pressed.

something linke in C:

while ( !kbhit() )

{

do something

}

there's probably lots of way to do this - if you want to maintain the event/while loop structure, you could use a Master/Slave method.

this is exact what i wanted. thank you.

is there also a possiblity to start and stop with the same button  for ex. "a ".

again - lots of ways to do this.
The attached example is just the fastest I could modify the previous version
