Simple Function Questiion

[bebandit]

If I have a function that returns a boolean(true/false) and I want to wait for the function to return the boolean BEFORE The program goes on to the next function, would something like this work??

 
dim answer as boolean=false

'Call function getanswerdunction()

answer=getanswerfunction(parameters)   'eventually returns true

while answer=false
loop

nextfunction()

or is there a better way??

Cheers,

Unless I'm misunderstanding you, you'd never proceed to nextfunction until you broke out of the loop. But the call to getanswerfunction needs to be in the loop. Right now it executes once, returns whatever, then goes to the while loop. If getanswerfunction returned false, you'll be stuck in an infinite loop. It'll never be true.

That's what I thought, but will putting it in the loop make it call the function over and over again?? Or will it just loop until the answer=true without calling the function over and over?

it will call the function each time through the loop.... how else would answere get set?

It sounds like you need to look into Threading...

Hi,

I'll take a guess here.

If you are saying that you want to wait until the user makes a selection that changes a boolean variable, why not just use a messagebox?

Perhaps you should tell us what changes the boolean.
