code problem while online

[harrisonmulline]

hi
i have created a dynamic photo gallery that counts the amount of images in a folder (found the code somewhere) and displays the thumbs. It works perfectly offline but not online or while i am using the 'simulate download' feature. I have figured that somehow it hasn't got enough time to count the images or something.

heres the code that counts the images:

stop();

var NumImages:Number = 0; 
function ImageExists(Num) { 
    var LV:LoadVars = new LoadVars(); 
    LV.onLoad = function(ok) { 
        if (ok) { 
            NumImages += 1; 
        } 
    }; 
    LV.load("gallery"+"/"+Num+".jpg"); 
} 
for (i=1; i<300; i++) { 
    ImageExists(i); 
} 
function ShowNumImages() { 
    trace("Number of images found: "+NumImages); 
	   clearInterval(Update); 

} 
Update = setInterval(ShowNumImages, 1000);

Please help me with the problem.

try this instead (untested)

stop();

var NumImages:Number = 0;
function ImageExists(Num) {
    var LV:LoadVars = new LoadVars();
    LV.onLoad = function(ok) {
        if (ok) {
            NumImages += 1;
        }else(ShoeNumImages());
    };
    LV.load("gallery"+"/"+Num+".jpg");
}
for (i=1; i<300; i++) {
    ImageExists(i);
}
function ShowNumImages() {
    trace("Number of images found: "+NumImages);
} 

the code u posted was using a setInterval to retrieve the number of images at the end of one second rather than just using the onLoad(ok) function used which is weird.. probably coded by one person then hacked by another.. o well give mine a try, it should work for ya!

thanks for your answer ryan, but theres a problem. your code only executes the ShowNumImages function if it hasnt found an image.

if (ok) {
            NumImages += 1;
        }else(ShoeNumImages());
    };

I have tryed changing it and got into problems because once it has finished counting the images i need to - (gotoAndPlay(2).

have you got any other ideas?
thanks so much for your help!

hello again!

I must be confused, wouldn't you want the shownumimages function to only run once all the images are counted?

If you want to goto frame 2 once all the images are counted you would just add
gotoAndPlay(2); right after the trace in ShowNumImages

hey
it was confusing me too, i played around with that bit of code for ages and getting no where decided to recreate it using onEnterFrame. To my surprise it worked!

here it is
frame 1:

stop();
var LV:LoadVars = new LoadVars();
LV.load("gallery/"+(_root.galleryname)+"/thumb"+_root.ic+".jpg");

LV.onData = function(src:String) {
    if (src == undefined) {
        this.onEnterFrame = null;
        trace("Error loading content.");
        gotoAndPlay(3);
        return;
    }
    else{
        trace("ok");
    }
};

trace(LV);
this.onEnterFrame = function() {
    trace("it is loading");
    var loaded:Number = LV.getBytesLoaded();
    var total:Number = LV.getBytesTotal();
    var percent:Number = int(loaded/total*100);
    trace(loaded);
    if (loaded>4 && loaded>=total) {
        trace("loaded");
        // this.changepic.play();
        this.onEnterFrame = null;
        gotoAndPlay(2);
    }
}; 

frame 2

stop();
if(_root.ic<300) {
            _root.tn ++; 
    _root.ic++;
}
gotoAndPlay(1); 

thanks for your support ryan, your code helped me get to the solution.

u bet! glad you got it working
