actionscript 3 runtime variables

code :: setting them with php

the key to creating dynamic systems on the web is the ability to send and receive data from one component to the next. flash and flex are no different. there are a lot of cases where you need to send these variables while the application is running, but there are an equal amount of times where the application needs data at run time. passing variables to flash historically has been rather easy, you just query-string data right into the src tag of your flash movie:

src="test.swf?passed=hello"

by doing this flash would create a new variable (in this case named passed) when the flash movie is loaded. but with the advent of OOP coding in AS3, this technique has become depreciated. 

in actionscript 3 you need to use the flashvars parameter to send data to your flash movie. the technique is the same for both flash and flex, but once the variable is passed flash and flex has a different syntax to access these vars.

asp.net random number generator

code :: the central randomizer

here is my asp.net randomizer class based on the c R250/512 shift-register sequence random number generator, by kirkpatrick and stoll and published (j. computational physics, vol 40, pp. 517-526) with an added a pseudo-random class redefinition and buffer overflow protection.

example usage:

randomizer x = new randomizer();
int num = x.random();

dotnet sendmail

code :: sending email with c#

sending email is a snap with asp.net 2.0, this simple function sends an email to the specified name and email you pass to the function. with a little database integration this can be recalled in almost infinite recursion, and will not be tagged as spam because it sends individual emails, not a bulk message to many users. for fastest delivery times specify the direct path to your mail server (see line #18), and setup your mail server to not scan outgoing  webserver mail for spam. *edit* i now recant that statement. true, pure execution times will be faster but at the sake of ignorance. i would rather have the slightly increased send time and the knowledge that my code has not be hijacked and sending spam. 

example usage:

sendmsg("xero", "x@xero.owns.us");

asp.net pure code database connection

code :: three different ways

visual studio 2005 has a tool for connecting to a database called a "sqlDataSource". while this tool works, i find myself wanting to create the connection and build or execute stored procedures within my own C# code. this tutorial will show you how to connect to a sql database 3 different ways in asp.net

the first thing is creating a connection with your database. if you understand how connection strings are built, write your own other wise will can use the visual studio database tool to do that for us.

3D sound visualizer

code :: papervision3D spikey ball

papervision3D sound visualizer

a fellow papervision3D enthusiast zeh (creator of the popular mctween) has created a new way of animating full 3D objects in the flash/flex environment with 100% code! introducing the caurina tweener, which is now hosted on googlecode. tweener is still in development, but is completely stable and functional.

check out the sound visualization demo i created using pv3d and tweener

papervision3D video material

code :: the lupin cube

papervision3D video material - the lupin cube

 

my latest papervision3d project was a revamp of the video cube. this time around the rotation of the cube is static, not mouse driven, also i added some new filtering, and a different method of using a video texture that doesn’t throw an error message. the flv is from the best cartoon ever lupin the 3rd. this episode is called "buns, guns, and fun in the sun" 

check it out here.

and here's the as3 code:
