So, now you're wondering if we're ever going to talk about the User Poll. Okay, here it goes.

Let's say you want to do a little market research and you want to put a User Poll on your site. Well, you probably don't want to have to create a new Flash movie every time you want to ask a different question. So, what are the things that your movie needs to do so that you don't have to mess with the FLA every time? You'd definitely want to be able to pass in the text for the question. But what if one week your question has 4 answers and the next week you want it to have 7? How can you have one SWF that works with a dynamic number of possible answers? The answer lies in the awesome ability to Duplicate Movie Clips.

To accomplish the seemingly daunting task of having a dynamic number of possible answers, you need to pass in a value to Flash representing the number of answers that you want to display. Then, you'll want to Loop through some code to Duplicate your Movie Clip the correct number of times. Here's a code snippet:

Loop While (/Variables:cntrButtons <= /Variables:cntrAnswers)
Duplicate Movie Clip ("/Variables:/btnAnswer", "btnAnswer" & /Variables:cntrButtons, 
Set Property ("/Variables:/btnAnswer" & /Variables:cntrButtons, X Position) = 
Set Property ("/Variables:/btnAnswer" & /Variables:cntrButtons, Y Position) = 
Set Variable: "/Variables:lasty" = /Variables:lasty + 25
Set Variable: "/Variables:/btnAnswer" & /Variables:cntrButtons & 
        "/:atext" = Eval ("/:a" & /Variables:cntrButtons)
Set Variable: "/Variables:cntrButtons" = /Variables:cntrButtons + 1 
End Loop
Set Property ("/btnAnswer", Visibility) = false

The code above will loop through a set number of times, create a new instance of the Movie Clip being used as an answer, stagger the new Movie Clip down a ways from the previous one (so they don't stack on top of each other) and put the corresponding text for the answer into the text field within the Movie Clip. So, now you have a loop that will create the correct number of answers and position them in the appropriate place.

» Description: Hmm... what to say about this one? It's reminiscent of the closing notes of the opening music from the Three Stooges done in a church organ style with a closing cymbal crash. I'll give this one away gratis, but feel free to check out my free loops and potential upcoming license-mandated ones over in the respective part of Flashkit.
