Re: FLASH: waiting for LOAD VARIABLE results

[Wolf Luecker]

Hi,


sorry for butting in on this thread. I'm relatively new to this list 

(although not to Flash) and I might have missed earlier posts on the 

same subject.


Helen, I've banged my head against this sort of thing a few times and 

I still haven't found a really safe and elegant way of telling 

whether Flash has received a bit of data or not. Branden's solution 

(checking for one certain variable that is always returned) is the 

one I use, too, so I can only suggest a couple of little things to 

safeguard that your code is correct.


In the 'if' loop I actually use the 'Length' expression, as in

If (Length(varx) > 0)

   Goto labelx and Play

That seems to be the safest one for me. Also, make sure you're not 

checking for the string literal "0" but for the expression 0 or 

'false'. And finally, assuming that your button with the 'load 

variables' action also moves the movie on to Frame 2, maybe Flash is 

too slow to register the first action and never manages to load the 

vars before moving to Frame 2. Maybe put a frame in between those two 

actions? (this is a far shot, I must admit)


Just my thoughts,


Wolf.
