User input during postprocessing

[Rory]

I have a post set up to ask a question of the user when they post a file. The window that pops up allows the user to input the needed data which is then written into the code for the CNC machine. Right now a person can just blow through the screen which leaves a blank space in the nc file. Does anybody know how to set up a check that the post will do to see if the entry was blank? If it is left blank, I do not want posting to continue but rather return to the screen and wait for user input again.

if you are using a string, you could define a string

snull ""

to which you can compare the value of the answer and then ask again the question if needed.

 

something like this maybe:

 

q1 #question call

while (sanswer = snull),

[

q1

]

 

sanswer being the answer from the prompt screen

this way as long as the answer is null, you stay in the loop. Just make sure you don't create an infinite loop.

Another way could be the following:

q1 #question call

if swanswer = snull, q1

this way if the answer is null, it will ask again the question.

That worked just like I wanted it to.

Maybe I will add a timer so that it can't get caught in an infinite loop. If it times out it can exit the posting process.

 

Isnt there a command called "exitpost" or something similar that will let this happen?

[André Lapointe@In-House Soluti]

yes there is this function.

it could be part of a condition like this:

 

q1 #question call

while (sanswer = snull),

[

q1

counter = counter + 1

if counter = 15, exitpost$ #put the value you want here for the counter

]

 

same idea for the other solution I gave you earlier.

I think there needs to be a wait function something like this;

 

q1 #question call

while (sanswer = snull),

[

q1

counter = counter + 1

Wait 1

if counter = 15, exitpost$

]

 

 

But I am unsure of how to add the wait in the correct format for the post.

[André Lapointe@In-House Soluti]

I don't know of any Wait function, but it doesn't mean it doesn't exist. So far, without the wait function it should work the way you wrote it.

Let me know.

[Roger Martin from CNC Software]

There is no 'WAIT' (timer) function.

 

What André posted above using a counter int a loop should work.

Thanks for the help. I was able to get it to work.
