Scrollbar Equation Help
hi everybody. i made a scrollbar to scroll a masked textbox, but can't seem to get the equation right. can anybody help??

i have an MC called textBg, and the MC to be scrolled, called textBox. i calculate the difference between the two, and scale the scrollbar (scrollHandle) appropriately on top of an MC called scrollBg. (scrollBg is the same height as textBox, if it makes any difference) the y position of textBox is relative to textBg, which is stationary.

so far i've declared some variables, and tried using them... not sure if they're useful though:

Code:
var textDiff = textBox.height - textBg.height; // size difference - text scroll amount
var maxScroll = textBg.y - textDiff; // maximum scroll distance
var scrollDiff = scrollBg.height - scrollHandle.height;
i've mucked around with different equations, involving scrollHandle.y, but can't seem to get it to work correctly. i really suck with numbers, so any help would be greatly appreciated! i hope i explained myself well enough. thanks!

Dynamic Thumbnail Next Row Equation
Hi Guys,

Got a problem with my loop. I have the y values sorted out, but the x value is stumping me. I need it to return to the initial x value of the first thumbnail so i can have a stack of thumbnails. The code is as follows:

__________________________________________________ _____________
rowcount = 1
countup = 0
roww = 0
//setup thumbnails
for (tn=1 ; tn<50 ; tn++) {
duplicateMovieClip(thumbholder, "thumb"+tn, tn);
eval("thumb"+tn)._x = ((tn*35)+148) <<<< equation ??
eval("thumb"+tn)._y = (rowcount*30)+70
countup ++
trace(eval("thumb"+tn)._x)

if (countup>4) {
< to change x value to ??
rowcount ++
countup = 0
}

__________________________________________________ ____________

I know I have to put something in the if test to change the equation for the x value of the thumbnails..not sure what..and I also know that the equation in the for loop has to contain something that takes the if test into consideration...not sure what the equation is.

Any help is greatly appreciated.

Scrollbar (dynamic Scrollbar Size)
Hi everyone.
I'm making a scroller that scrolls movieclip (text inside). It works quite good but I want to put the final touch on it.

I want that my scrollbar is dynamic in its size (just as browser scrolls or windows scrolls). Then my biggest programming problem comes up, maths

The values that I have is
- How tall is the area there the text shows.
- How tall is the movieclip that the text is shown in
- How tall is the place there my scrollbar is shown.

Someone thats have an idea how to sort this out

Dynamic Scrollbar?
i'm loading some text into a dynamic text box

can i make a scrollbar appear ONLY if needed (i.e. if there is x amount of text?)

cheers

Dynamic Scrollbar
Here is how far I have got.

Made a text area. set it to dynamic text
filled the box with text.
Made it scrollable.
Added up and down buttons.
Used
on (press) {
this.(thetextname).scroll +=1;
}
and -=1 respectivley

Now here is the question. How do I get the scrollbar to work by holding the buttons down, instead of having to click and click (hence the moving +/-1)

I am in flash8. I dont seem to need to make a mask as it all works up to now without one. I dont want to use the UI component it does not fit in with the page. anyway surely by now there is just a little code I can add here to do this?

Thanks

[F8] Dynamic ScrollBar
I have movieclips that gets duplicated and alligned one below the other just like a scrollable menu items inside a movie clip.
So when more than 10 movie clips are duplicated inside my main movie clip i should get a vertical scroll guide on the side. So, you can drag this scroll guide up and down, and hence making the duplicated movieClips move up and down. As the movieClips gets increasing in population this scrollbar automatically decreases in size and there by has a long way to get dragged vertically. I just like to know the logic behind making this scroller work.
how to function it dynamically ??

Dynamic Scrollbar That Uses PHP
So I've been searching everywhere and I can't seem to find a scroller that will allow me to import a PHP file instead of an XML file. Well I do have one of my own, but it only has buttons and no dragger. Anybody have some handy dandy links? I have the BillyT Scroller which says in the comments that it supports php and xml, but I changed the file that's imported to a php file and I get blankness. I think this is due to all of the XML commands in the rest of the script maybe. Anyway Thanks in advance for any help you have to offer,
Casey

Dynamic Text And Scrollbar
i'm a major newbie at this, so here goes.

i'm using flash mx and have learned how to add a scrollbar as well as load dynamic text from a .txt file. no problem. now, i've tried to combine the two so that i can have a text area that is loaded with dynamic text from an external .txt file that allows a vertical scrollbar. am i making sense?

anyway, i've tried and although i can get these two aspects working separately, i can not get them to work together.

any advice/suggestions etc would be greatly appreciated! thanks!

Dynamic Text W/ Scrollbar
Okay, I am using a dynamic text box to load the text for a the variable, "autobio". It works fine, but when I try to add the preset component scrollbar, it does not seem to work with the dynamic text box. I have set the target text box to "autobio", but it still doesnt work. I am probably doing something really simple, just unknowingly.

Please view my FLA if you want to see what I am talking about. Please ignore the "_level0.autobio" message. It only says that because I have my variables load in Layer 1, and my main movie file loads this file in layer 1, so that is nto a problem.

Dynamic Attachment Of ScrollBar, Help
I am trying to dynamically attach a Scroll Bar to an instance of a newly created Text field at run time.

The problem is that the Scroll Bar does not see the text field as its target. It appears on the stage, but the two are not communicating.

I have tried using the setScrollContent method, but it has not worked.

Any thoughts on how to dynamically attach a scroll bar to a text field?

Dynamic Txt Scrollbar - Flash5 To MX
Hello.
I've looked for other scrollbars options different from the scrollbar component
that comes with Flash MX. In fact i wanted just a simple draggable bar (no
buttons, etc.) that can be used with a dynamic textfield that gets its
content from an external source (like a txt file).

Unfortunately all the nice ones i've found were done in flash5, and they
don't seem to funtion after i export them as flash6 (and yes, i've used the
new loadvars standard and instance names...)

Anyway the kind of scrollbar i'm looking is like this (see in source, 6th link):

www.nooflat.nu

Already mailed its creator, but with no sucess. Anyone can help on this one?

Thx in advance,
T.

P.S.-If anyone could make the proper changes to that FLA and send it to me, i would be deeply grateful.

Help Dynamic Textbox With Scrollbar...
Hi!

I've got some problem with a dynamic textbox to which I added a standard scrollbar from flashMX. I tried to load the content from a txt-file with
"loadvariablenum("text.txt",0)"
but the text is not loaded whereas if I skip the scrollbar, there's no problem with loading the text.
I should tell that I have to use loadvariablenum because the loadvar-object seems not to be compatible with swish...

Thanx for your help!

Dynamic Text With Scrollbar
this has been driving me crazy for a while now, and the most annoying thing is that i know there is a simple solution!

when loading text from a .txt file into a dynamic text box i can't get the scrollbar to work. it snaps to my text field etc. and the text appears in the swf as it should but the scrollbar sits there all sad and dim!

i have been trying some stuff with onData etc. but i reckon i have the syntax all haywire. please, please, please can one of you pro-flashers out there help me out.

the odd thing is that it works if i place text directly into the textfield in the fla - but that's hardly dynamic is it!!

Scrollbar And Dynamic Content
hello

I have a scrollbar controlling a movie clip. The movie clip has graphics and some dymanic text content. This means that the movie hieght changes depending on which frame it's in.

I'm currently using a mask set to the max height of the movie clip but I would like he height to change according to the content. I was thinking I could set a variable which changes on each frame of the movie clip which could then be used to control the mask height.

Does this sound like a decent way to do it.. or can anyone suggest another way?

Dynamic Scrollbar With Loadvariablesnum? What The?
Okay I have a dynamic text field on the stage, instance name of news. the variable name is newsfield. on the first frame (fla only has one frame and one layer) has the following actionscript.

loadVariablesNum("newstext.txt", 0, "GET");

which works fine. but in thinking ahead I figured it would be easy now to add the scrollbar for when the information is more then the text field can handle and needs to scroll. So I checked the help added a scrollbar and it now doesn't load the text file.

when using the test movie i get this message

Error opening URL "file:///C|/Documents%20and%20Settings/username/My%20Documents/My%20Webs/aida%20Flash/newstext.txt?FUIComponentClass=%5Btype+Function%5D &FScrollBarClass=%5Btype+Function%5D"

but yet the only thing i have done is add a scrollbar.

attached files needed PLEASE HELP! this is driving me nuts.

thanks in advance

Can Someone Help With A Scrollbar And Dynamic Text Box
Hi all,

I have been trying to get a textbox that loads dynamic text to scroll using a dynamic scrollbar using actionscript.

I took an example from Joshua Davis's Flash to the core website. I used his scrollBar example and tried to adapt it to a horizontal version and instead of it scrolling a movieclip it would see how many lines of text there were and scroll it.

I have kind of struck a dead end and cant get the scroller to interact with the textbox. I have attached the file I am working on and in the hope that someone might take a look at it and see if they can get it to work for me or tell me how I can change the code so that it works properly.

If anyone could take a look at the file and tell me what I am doing wrong then I would really appreciate it. I look forward to any replies.

Printing Dynamic MC In Scrollbar
Hello all,

I'm having serious issues trying to print an MC I have in Flash. I've tried various methods, but nothing works so far, hopefully somebody has done this or knows where I can find information on how to do it. So here's my dilemma...

I have an MC that scrolls. The MC has dynamic content in it that gets passed from the submit button on the previous frame. The mask that allows the MC to scroll is set dynamically by the scrollbar.

It seems as though I am throwing every issue you can at Flash in order to print. I've thought of not making the MC scrollable and putting in on a different layer, then printing that MC. However, since there is dynamic content, the print button isn't passing the variables to the MC.

I've thought of printing the MC inside the scrollbar, but since the mask is set dynamically, it just prints out white pages.

I've thought of doing away with the dynamic mask, but then the dynamic array under the mask doesn't display.

I am at my wits end and would be eternally thankful of anyone that could help out or point me in the right direction.

As a matter of fact, I could probably pay someone to do it.

Thank you all in advance.

Dynamic Text And Scrollbar
I was actually hoping that you'd be able to offer me some help on a question I have about a scrollbar. I'm using flash mx2004. I've got a dynamic text box, with loads a separate .txt file. I've attached a scrollbar to it, and it seems to have snapped and attached correctly, but it doesn't actually "Scroll" when I test the movie. Very odd. I have multiline selected, and I also have "scrollable" selected on the text box.

Here are links to the files that you can download and take a look (I would SO appreciate it!!)

Dynamic Scrollbar Logic Help
I'm creating a dynamic scrollbar that doesn't use fixed numbers. One vertical scrollbar is the controller, and it effects the position of a movieclip "circle" inside a horizontal box movieclip. I want to be able to resize both the scroll bar and box and still have the circle move from one side to the other of the box (not just the height of the scrollbar controller).

Here's my code, please help with the logic on getting the circle._x to equal slider._y and move correctly! Problem is inside "slider.onEnterFrame" function.

stop();
scrollspeed = 5;
//created variables for height of scrollbar and width of box
slidebarH = slidebar._height;
boxW = box._width;

slider.onEnterFrame = function() {
//records percentage location of slider on sliderbar
sliderPos = (slidebar._y+slidebarH)-(slider._y);
sliderPercent = Math.floor((sliderPos/slidebarH)*100);
//records percentage location of circle inside box
circlePos = (box._x+boxW)-(circle._x);
circlePercent = Math.floor((circlePos/boxW)*100);

};
slider.onPress = function() {
slider.active = true;
};
slider.onMouseMove = function() {
if (slider.active) {

slider._y = _ymouse;
}
if (slider._y<=slidebar._y) {

slider._y = slidebar._y;
}
if (slider._y>=slidebar._y+slidebar._height) {

slider._y = slidebar._y+slidebar._height;
}
};
slider.onRelease = slider.onReleaseOutside=function () {
slider.active = false;
slider.stopDrag();
};
scrollup.onPress = function() {
onEnterFrame = function () {
if (slider._y>=slidebar._y+scrollspeed) {
slider._y -= scrollspeed;
} else {
slider._y = slidebar._y;
}
};
};
scrollup.onReleaseOutside = scrollup.onRelease=function () {
delete onEnterFrame;
};
scrolldown.onPress = function() {
onEnterFrame = function () {
if (slider._y<=slidebar._y+slidebar._height-scrollspeed) {
slider._y += scrollspeed;
} else {
slider._y = slidebar._y+slidebar._height;
}
};
};
scrolldown.onReleaseOutside = scrolldown.onRelease=function () {
delete onEnterFrame;
};
slidebar.onRelease = function() {
slider._y = _ymouse;
};

Dynamic Scrollbar Problem
Hello,

I'm having a scrollbar problem.
If I scroll down in one photo/textbox and go the next photo/textbox, the scrollbar resets to the top.
But...if I scrolldown, and then go to another category, the scrollbar stays at the bottom for the first photo/text in that category. Then, when I advance to #2 in the new category, it resets.
Any ideas?

Dynamic ScrollBar Control
Hi, I've made a textField with an attached scrollBar. Using my_textField.maxscroll I determine when the scrollbar is needed and when I want to hide it (._visible = false). Two events can trigger this:
when text is added/deleted so that it exceeds/fits inside the textField area
when the textField is resized

The above one is controlled with a textField.onChange event handler and works flawlessly, the second one, however, causes me some trouble.

Here's what I do:

Code:
textField_mc.my_textField._width = __width;
textField_mc.my_textField._height = __height;
...
textField_mc.my_scrollBar._visible = (textField_mc.my_textField.maxscroll != 1);
The problem seems to be that the .maxscroll value doesn't update directly when the size is changed. As soon as I click on the stage the value is updated, but then I've allready passed the test and the scrollBar remains visible/unvisible.

Is there a way to update or refresh the TextField after it is resized so that all parameters are set according to the new size? Or how else can I get around this problem?

Moviesclip Dynamic Scrollbar
Hey all im new to these forums

I have a problem with a website im trying to make... i need to have a scrollable movieclip with a scroll bar & slider, i need the code/formula for the position of the slider, which changes position based on the position of the movieclip(basically like a smaller version which shows what you are looking at). Now i want this formula to be dynamic and change based on the size of the movieclip and im really not sure how to do it... a long time since ive bothered with this kind of stuff. Maybe theres a function in flash mx which will help me?

Thx for any help

Dynamic Scrollbar Height Help
Hi Guys wonder if there is anyone out there that can lend a hand.

I have built a custom scrollbar sytem for a content MC (based around Lee Brimlows tutorial over at gotoAndLearn) But i cant figure out the logic behind resizing the scrollbar thumb based on how long the content MC is. If i knew the Math behind it im sure i'd have solved it by now but i just can't seem to figure it out.

Is it Thumb.height = (content.height / mask.height) * .... ???

Any help hugely appreciated guys!!

Scrollbar On Dynamic Text
sorry if this is an ongoing question from newbs or not

Ive used the scrollbar component on a dyn text box and it works fine when i test the scene, but when i test the whole movie the scrollbar doesnt work. It is greyed out.

I have no idea why this is happening. Any suggestions?
I even tried making my own through various tutorials but got lost pretty fast.

thanx in advance

Scrollbar, Dynamic Text
Hey,

I've got a system setup where you can visit a PHP page and it will get some text from a database and display it in a little flash area. It's great, except....
I have put a Dynamic text box and a standard-issue flash scroll bar together. But, guess what, it doesn't work. I've read that it doesn't work straight off with dynamic text like this. So how would I make it work? I presume some fancy actionscript!

Many thanks,

Ben

Dynamic ScrollBar In 2004 Pro?
Hey there...I'm having more than a few problems with my dynamic text boxes in MX 2004 Pro. I can't find the ScrollBar component in the Library, and I thought that I heard that MX 2004 automatically inserted a scrollBar on dynamic text fields...or is this one of those things that got taken out of the Pro version, so that Developers can create their own? If so...that's fine, but I wish I'd known that.

Any ideas?

Scrollbar For Dynamic Text.
I'm looking for a nice scrollbar (component maybe) for dynamic text. I've been using the FFH Text Scrollbar component for a while as well as the UI Scrollbar Component. Both are good (FFH ligher in size).

I'm looking for a scrollbar that doesn't dynamicly scale the scroller in the middle though.
I have seen some like this for dynamic text on some websites but never have been able to find one (or figure out how to write one).

Scrollbar With Dynamic Text
I was wondering if anybody here had any idea how to make a scrollbar that would scroll text in a dynamic text box that loaded a text file... I can't really find any tutorials anywhere that are specifically for that, and even when I do they either assume you know too much or they have a lot of bugs in them. I started with the scrollbar tutorial from kirupa.com and finished it successfully, but I could not figure out how to get it to work correctly with dynamic text.

help would be appreciated, thanks.

Using A Mathematical Equation?
Hey guys,
I'm wanting to make a jazzy flash movie that randomly fills the window with little boxes starting from the middle. Sort of like on the loading page of Der Baurer's (spelling?) web site but different in the sense that the boxes are smaller.

I'm wondering if there is some mathematical equation of some sort that could do this automatically since manually animating this would be next to impossible.

Has anyone ever tried this before or know if it can be done?

Thanks.

and the object's y position is dictated by the y position of the mouse and how far along the object is on the x axis.
