Super Easy Email Validation AS2

Admin — Fri, 20 Aug 2010 09:45:21 +0000

I needed a quick and easy way to check for the basics of an email address.

Does it contain “@” and “.” symbols.

This is by no meals a foolproof method, so don’t use it for anything big, but if you want to just do a quick test then here you go:

var email:String = "name@server.com";
if (email.indexOf("@")!=-1 && email.indexOf(".")!=-1) trace("false");

else trace ("true");

Random Number In ASP for no Flash Caching

Admin — Fri, 04 Jun 2010 08:12:37 +0000

This is an example of how to create a random number in Classic ASP in order to append to a swf file so that the browser does not cache the swf file.

<%

Dim SwfRndNum

Randomize

SwfRndNum = Rnd

%>

You can then add it to your swf embed code as follow, bear in mind that I am only showing the snippet around the swf file name and not the entire embed code.

mySwfFile.swf?a=<% Response.Write SwfRndNum %>

Error 1046: Type was not found or was not a compile-time constant: Event.

You need to import the Event class!

import flash.events.Event

Add a date to a date in Actionscript 2

Admin — Fri, 26 Mar 2010 20:19:42 +0000

I needed to work out a date range according to the date 3weeks away from the current date.
After a bit of thinking, I found that it’s actually quite easy to achieve.

var theDate:Date = newDate();

dateDay = theDate.getDate();

dateMonth = theDate.getMonth();

dateYear = theDate.getFullYear();
var theDate2:Date = new Date(dateYear,dateMonth,dateDay);

theDate2.setDate(theDate2.getDate() + 21);

dateDay2 = theDate2.getDate();

dateMonth2 = theDate2.getMonth();

dateYear2 = theDate2.getFullYear();span>

The above code gets the current date and adds 21days/3weeks to it.
Remember that if you use getMonth to output the final month number, you will want to add 1 to it as it starts at 0;
Example:

dateMonth2 = theDate2.getMonth()+1;

So you would do it like this:

theDate2.getDate() +"/"+ (theDate2.getMonth()+1) +"/"+ theDate2.getFullYear();

Add a month to selectable date range – Date Chooser – Actionscript 2

Admin — Mon, 22 Mar 2010 12:40:20 +0000

I have been working on a project where I need to select a date range starting today and ending a month from now, so the user cannot select anything in the past or over a month from now.

This is how I did it:

There is an instance of DateChooser on the stage with Instance Name “calDate”.

var todayDate:Date = newDate();

dateBeginDay = todayDate.getDate();

dateBeginMonth = todayDate.getMonth();

dateBeginYear = todayDate.getFullYear();
if ((todayDate.getMonth()+1)==12) {

        dateEndDay = todayDate.getDate();

        dateEndMonth = 1;

        dateEndYear = todayDate.getFullYear()+1;

} else {

        dateEndDay = todayDate.getDate();

        dateEndMonth = todayDate.getMonth()+1;

        dateEndYear = todayDate.getFullYear();

}

calDate.selectableRange = {rangeStart: new Date(dateBeginYear, dateBeginMonth, dateBeginDay), rangeEnd: new Date(dateEndYear, dateEndMonth, dateEndDay)}

Embed pound symbol (£) in flash textfield

Admin — Wed, 10 Mar 2010 13:55:36 +0000

If you use a dynamic textbox in Flash and you want to embed the British Pound symbol (£) then you will want to also embed the “Latin I” glyphs with your textfield.

Calling event functions from movieclips in actionscript 2

Admin — Wed, 24 Feb 2010 17:41:03 +0000

In a flash movie I usually have a frame of actionscript that controls all elements in the file to keep everything in one place.

Sometimes I have an onPress(etc) function that refers to something happening in the scene when something is pressed, but what happens if we want another element to refer to that event for some reason?

Here’s an example of that code without anything “flashy”:

_root.myMC.onPress = function() {

        //code goes here

}

..and here’s our slightly more intersting flashy version:

_root.myMC.onPress = _root.funcOnPress = function() {

        //code goes here

}

So now we can call the following from another place in the code to call the same event’s function:

//somewhere else in our flash file

_root.funcOnPress()

That’s about it folks!
Now you can call things from other places.
Just remember to not use “_root” if you are including your final swf inside another swf.

Security error: securitySandboxError with Flash

Admin — Wed, 17 Feb 2010 13:12:21 +0000

You have a flash uploader and you get this error:

security error: securitySandboxError

This means that the flash is not trusted by the domain and you have to place an xml file in the root of the domain.

The file is called “crossdomain.xml” and this is what should be inside it:

Solved!

Component Inspector in Flash has ISSUES!

Admin — Thu, 11 Feb 2010 13:14:32 +0000

I discovered a very annoying bug in the Flash IDE a little while ago, and it has happened to me quite a few times.

Today it happened again and so I write this post..

While in the Flash IDE you select a component on the stage, then you click “Component Inspector”.
This opens up into a modal window which is nice and everything BUT….
…..if you then give focus to another program and then try click back into flash, it hides the “Component Inspector” modal window but still keeps focus on it, so basically, you can’t use the program(Flash IDE) / save your file / or even close the program!

You will then have to use the Task Manager to End Process on that instance of Flash!

This can be very annoying and can lose you productivity by not allowing you to save, so these are your options:

1.) Save before using this feature
2.) Don’t EVER give focus to another application while in the “Component Inspector” modal window.

Place HTML Div on top of Flash

Admin — Fri, 08 Jan 2010 14:23:23 +0000

If you have ever tried to place a div or similar HTML element on top of a swf flash object you will know that it always tries to take precedence.

You will need to do the following:

In the code for the flash add:

<param name=”wmode” value=”transparent”>

and in the embed area add:

wmode=”transparent”

If you are using SWFObject to insert swf files you can do the following:

<script type="text/javascript">

var so = new SWFObject("movie.swf", "mymovie", "400", "100%", "8", "#336699");

so.addParam("wmode", "transparent");

so.write("flashcontent");

script>
