How can I show a frame of an avi movie, specified by a slider?

Hi. I am new to LabVIEW.
I want to show a frame from an avi file, where the frame is specified using a slider.
Could someone give me an idea of which  slider  can be used and how?
Thanks,
Akira

Hello Akira,

I'm not sure which version of LabVIEW you have, or which toolkits you have installed.  But open up your Example Finder.  (Under Help-->Find Examples)  Do a search for "AVI" and you'll find an example called AVI Read Write with Data Example. 

This is really good example and part of it includes a function for moving through the frames with a slider. 

Good Luck!

Thanks Patrick for showing me how to look for the solution.

One thing still I can't figure out  is:

The scale can be specified in the Propery of the slider. But how can it be done in the block diagram?
I want to use "Number of Frames" from "IMAQ AVI Get Info" to specify the maximum value.
(I'm using LabVIEW 8.20+Vision 8.21 trials)

Create a property node for your slider (right-click...create..property node , select property "Scale..range...maximum", change property to "write") and wire your number to it.

Thank you for the trick. Now it worked exactly as what I wanted.

I really appreciate the help from both of you.
