Capturing User Input Restricted To Just Numbers?
I’ve written a function that restricts user input to just numbers (0-9,.) and stores the input in the associative array, userInput[]. It works but seems inefficient looping through the entire input text string to scrub out invalid characters. Anyone have suggestions for a more efficient approach? Note that a working solution must correctly process mouse or cursor key movements/edits within the input box.
Also, you can see I’m using the KeyboardEvent.KEY_UP event to trigger the processing. The docs seem to indicate TextEvent.TEXT_INPUT is really the proper event for this purpose. I started with TextEvent.TEXT_INPUT but found the event is triggered before the last key pressed is actually added to the instance. The result is that the function was always one character behind. Is there an easy way to get the current text in the input box, including the last key pressed, when processing TextEvent.TEXT_INPUT?
Attach Code
someTextInputInstance.addEventListener(KeyboardEvent.KEY_UP,numInputCapture);
//--------------------------------------------------
function numInputCapture(e:KeyboardEvent):void {
var myTargetName:String = e.target.name;
var myTargetText:String = e.target.text;
var numChars:Array = ["0","1","2","3","4","5","6","7","8","9"];
userInput[myTargetName] = "";
for(var i:uint = 0; i < myTargetText.length; i++){
var testChar:String = myTargetText.charAt(i)
if (numChars.indexOf(testChar)>-1) {userInput[myTargetName]=userInput[myTargetName]+testChar};
if ((testChar==".")&&(userInput[myTargetName].indexOf(".")<0)) {userInput[myTargetName]=userInput[myTargetName]+"."};
};
e.target.text = userInput[myTargetName];
};

Movement Of MC _y Is Restricted?
lo guys and dolls,
I wonder if you might be able to shed some light on my problem, I am using two bits of code to move an arrow down a list of text items, when the text items are clicked the code is updated with the new value and the arrow moves down to that.
However it is hitting a point where it cannot go any further, even though I click a lower text item, I have traced the value substatusarrowMove1 which gives me the new value each time the timeline is returned to frame one for it, and in turn travels onto frame two and then frame three and in turn is looped back to frame 2 to continually adjust the movement.
substatusarrowMove1 return figure such as the original value+ the 33.3 for example, and then arrow moves there, but this value gets to something like 477 and will not go any higher.
I'm not sure why, any help or solution would be much appreciated.
Cheerz peeps
//The first piece of code is on the first of three frames:
substatusArrow = _root.submenuFurthest;
// then use this to put the arrow in the right place x33.3
substatusarrowMove1 = +24+(33.3*substatusArrow);
//the code in the second frame:
substatusarrowMove2 = getProperty("substatusArrow", _y);
substatusarrowMoveDif = (substatusarrowMove1-substatusarrowMove2)/10;
setProperty("substatusArrow", _y, substatusarrowMove2+substatusarrowMoveDif);
//and on the third frame is a gotoAndPlay frame 2 to loop back to the above.

Restricted Swf Re-sizing Possible?
I have a swf embeded in an a table with-in my html index. I want to enable the automatic shrinking of the entire swf when browser resizing (to allow entire swf viewing on smaller screens) but want to restrict any enlargement past the swf's true (actual stage pixel dimension) size when browser resizing (on larger screens) as to avoid pixelation of non vector artwork within the swf.
Is this possible and how do I do it? I know how the theory should work but I do not know if what i need is action script, js, html even? And what the specifics of the code would be?

How To Use Restricted Keyword?
Hi all,
I'm trying to do something like this:
Code:
var this_variable:XML = <stuff>get</stuff>;
But I get an error because "get" is a restricted keyword. I tried wrapping it in quotes but that doesn't work -- how would one get around this? I just want the string "get" inside of <stuff> tags. Thanks!

Restricted MC Rollover Area
I'm trying to make a MC follow the mouse arrow, but only in a small area...i can make the MC move all over the screen using,
Code:
onClipEvent (enterFrame) {
_x += (root._xmouse - _x)/10;
_y += (root._ymouse - _y)/10;
}
then i found a code in these forums that seemed to work for person who needed it, but not for me...it goes
Code:
onClipEvent (enterFrame) {
var dx = root._xmouse - _x;
dx /= 10;
if (_x+dx >= 50 && _x+dx < 150)
_x += dx;
var dy = root._ymouse - _y;
dy /= 10;
if (_y+dy >= 50 && _y+dy < 150)
_y += dy;
}
the MC doesn't move around at all...i'm using MX2004 pro (even tho i can't figure out this code)..basically i'm trying to get an effect simlilar to the star at fc ukstar.com <---had to put the space between fc and uk otherwise it automatically turns to 4 asterisks, funny...

Flash In PDF - Restricted Networking
The Flex 3 documents state:
"You can control a SWF file's access to network functionality by setting the allowNetworking parameter in the <object> and <embed> tags in the HTML page that contains the SWF content."
However, there is no information about the networking mode when Flash is run from within a PDF. There is no such thing as an object or embed tag in this case, so how do you control this setting? Or if you cannot, what setting is used in this context?

If an AS 2.0 swf is loaded into a AS 3.0 swf, does it, the AS 2.0 swf, lose the capability of loading in other AS 2.0 swfs?

Send To Mysql Restricted Data
How to resolve this?
I have a php with a user logged in (with a session), where lots of mysql data is load into a flash.
Now my problem is backwards, from that flash I need to save the data modified on mysql.
That could be easily done just by sending all information that I want to modify on mysql on the address with ?do=....&f=..., but since part of this information is the userid I really did not want this procedure or someone could try to modify what is not from them. In order to identify I could also add the password on the variables sent but that would become easy to try to hack each other passwords.
Is there anyway to send this modifyed data to mysql and also username and password to authenticate the user and to preven to just have access to modify the user data?
Thanks in advance

Object Following Mouse In Restricted Area
Ok… yesterday in the night I start doing some code and one of the functions that is the last one and I thought the easier is driving me crazy.
I want to make the buttons keep flying on the stage following the mouse but in a restricted area. I have tested 2 ways to do that but without luck… I’ve searched over the forums, tutorials and now I don’t know what else I can do!
ActionScript Code:
for (i=1; i<4; i++) {
this_one = this["sqr"+i];
this_one.centerX = this_one._x;
this_one.centerY = this_one._y;
this_one.onMouseMove = function() {
xdis = (_xmouse-this._x)/100;
ydis = (_ymouse-this._y)/100;
if (xdis>0 && ydis<0) {
//trace("quadrant1");
if (this._x-this.centerX<5 || this.y-this.centerY<5) {
this._x += xdis/10;
this._y += ydis/100;
}
} else if (xdis<0 && ydis<0) {
//trace("quadrant2");
if (this._x-this.centerX>-5 || this.y-this.centerY<5) {
this._x += xdis/10;
this._y += ydis/100;
}
} else if (xdis<0 && ydis>0) {
//trace("quadrant3");
if (this._x-this.centerX>-5 || this.y-this.centerY>-5) {
this._x += xdis/10;
this._y += ydis/100;
}
} else if (xdis>0 && ydis>0) {
//trace("quadrant4");
if (this._x-this.centerX<5//|| this.y-this.centerY>-5) {
this._x += xdis/10;
this._y += ydis/100;
}
}
};
}
and the second one with hit test
ActionScript Code:
for (i=1; i<4; i++) {
this_one = this["sqr"+i];
this_one.centerX = this_one._x;
this_one.centerY = this_one._y;
this_one.onMouseMove = function() {
xdis = (_xmouse-this._x)/100;
ydis = (_ymouse-this._y)/100;
if (this.hitTest(res1) || this.hitTest(res2) || this.hitTest(res3)) {
this._x += xdis/2;
this._y += ydis/2;
trace("hit");
oldhitx = this._x;
oldhity = this._y;
} else {
if (this._x-this.centerX>0 && this._y-this.centerY<0) {
trace("111positivo "+this._name);
this._x -= xdis/2;
this._y -= ydis/2;
}
if (this._x-this.centerX<0 && this._y-this.centerY<0) {
trace("222negativo "+this._name);
this._x += xdis/2;
this._y -= ydis/2;
}
if (this._x-this.centerX<0 && this._y-this.centerY>0) {
trace("333negativo "+this._name);
this._x += xdis/2;
this._y += ydis/2;
}
if (this._x-this.centerX>0 && this._y-this.centerY>0) {
trace("444positivo "+this._name);
this._x -= xdis/2;
this._y -= ydis/2;
}
}
};
}
any idea?!?!
as u can see now all my code is a mess
I’m very tired

Random() Rotation Restricted Values?
Hey guys/gals. My question is, can you restrict values to a "random()". For example, I want to rotate a bunch of MCs randomly so they all looked a little different, but obviously if something is rotated upsidedown, that would look kinda dumb, so I want to restrict the degrees that my MCs rotate. Can I set parameters so that my MC won't rotate more than 75 degrees one way (counter clockwise) and 75 degrees the other way (clockwise), but for each MC, do it randomly?
Thanks in advance,

Content Not Appearing On Restricted Windows Account
Hi all,
I have a flash file in which certain items are set to Export for AS.
"Export in first frame" is unchecked and those items are placed on the
stage some frames after frame 1 to allow for a small loader bar.
All's fine on a whole lot of machines (Mac, PC and all sorts of
browsers) except for a group of PC's which run on a restricted
useraccount and run only Internet Explorer. On those machines the items
set to "Export for ActionScript" but not in frame one are not shown.
Does anyone have any ideas?
QAD workaround I suppose could be to have it all load in frame 1 and if
needed built a separate preloader but I would prefer to keep it all in
one file...
thanks in advance,
Manno

Actions For Numbers Between Two Numbers
I am trying to make a movie duplicate, and I got it all, EXCEPT, I want it to move over and line up in colums when the screen gets full going down. I started out with _y position = i*25, and that worked, but when it gets to the end of the screen I want it to do this y position= (i-15)*25 and x position = 250; could get that far... the problem is when it gets to the bottom the second time i need to do y position= (i-15)*25 and x position = 250 between 16 and 30, and the next "column" to be between 31 and 45 etc.
on (release) {
setProperty (_root.myMc, _visible, 0);
do {
duplicateMovieClip (MyMc, "MyMc"+i, i);
set (_root.myMc.i, _root.i);
_root["myMC"+i].minus = String(i);
i = i+1;
} while (i<=num);

sorted = array.sort()
the sort does not come out correct. all numbers are in ascending order except for the number "100", which i'm assuming it reads in as "10" because it groups the "100's" with the "10's" in ascending order. does anyone know how to make Flash put them at the end behind "99"? thanks!

How Big Can Numbers Be?
Hi,
Perhaps strange question, but currently I am trying to create a secure login script.
I am trying to convert a password into ascii signs, giving it 3 numbers for each letter of the password, so e.g. a password like 'hi'(two characters) would become something like '145178'(6 characters), or 'hello' something like '165134565656934'
Since I want to do some calculations with it, for encryption purposes, I must know how big a number can be in flash?
Is someone has a password like "thisismypassword", that would create 16x3=48 numbers.
anyone an idea?
