how to detect what version of Flash is installed on a system

[color red] Intention of this tutorial: [/color]
to understand how to direct the browser to the page corresponding to the FlashPlayer version the system has installed.
First you need to detect if any version of Flash is on the system. That you can check with a JavaScript. If there is, you can make a swf that detects the version of the Flash player installed and send the browser to a html page that has the content built in that kind of Flash.
--------------
Note:
it is easy to modify the code and make the browser just say what type of flash player the system has.
--------------
Step 1:
detecting wether you have any player for flash:
you make a HTML page and put inside teh following code:
let's say you call the page flahDetection.html
----------------------
----------------------
step 2:
make a picture and call it trafficSignRed.gif and put it in the same folder as the html.
This is the picture that will appear when you don't have any player.
---------------------
---------------------
step 3:
open Macromedia Flash and make a new movie, trafficSignGreen.fla. The result of this, trafficSignGreen.swf, has to be in the same folder as the html and gif file.
leave the first frame empty and add a new keyframe on frame 2. add the following actionscript to the frame:
that's all with the swf file.
Note: if you want it just to show what kind of player you have, and not take you to a different file, you have to change the getURL() command to a _root.gotoAndStop() command that goes to a different frame inside the movie for each version of the player. By the way, don't forget to make those frames and add some words or graphics to each frame.
-------------------------
-------------------------
step 4:
Now you have to make the html files for each version of the player.
make a flash3.html, flash4.html, flash5.html, flash6.html.
what's inside these html files is of your own choice.
put them all in the same folder as the swf, the gif and the flashDetect.html
====================
====================
that's about all.
It does work. If you want to check it, go to http://www.migroup.go.ro/swiffer/scriptDetection.html
it will redirect you automatically to the page corresponding to the flash player you have.

</HTML>let's say you call the page flahDetection.html
----------------------
----------------------
step 2:
make a picture and call it trafficSignRed.gif and put it in the same folder as the html.
This is the picture that will appear when you don't have any player.
---------------------
---------------------
step 3:
open Macromedia Flash and make a new movie, trafficSignGreen.fla. The result of this, trafficSignGreen.swf, has to be in the same folder as the html and gif file.
leave the first frame empty and add a new keyframe on frame 2. add the following actionscript to the frame:
Code:
// create a Flash variable, whose value is equal to the
// $version environment variable in Flash 4 or 5. This
// action line will not be read by Flash 3 (or earlier)
// Players.
player = eval("$version");
myOutput = player;
// The $version value will be in the format:
//
// abc 1,2,3,4
//
// where abc is the operating system (e.g. WIN, MAC)
// and 1 and 2 are the major version designations
// (e.g. 4.0, 5.0, etc.) and 3 and 4 are the minor version
// designations (e.g. r20, r27, etc.)
//
// By default, Flash 5 ships with a Player version equal to
// WIN 5,0,30,0 or MAC 5,0,30,0
//
// We just need the major version designation, at
// placeholder 1. Using substring(), we can extract this
// number. The major version starts at the 5th character of
// the version value. The Flash 3 Player will disregard
// this line.
player = substring(player, 5, 1);
// player will be equal to either 4 or 5 in Flash 4 or 5 Player, respectively.
if (player eq "") {
// Flash 3 Player will execute this code automatically,
// because it will need interpret the if action.
getURL("flash3.html");
} else if (player eq "4") {
// Flash 4 Player will execute this code.
getURL ("flash4.html");
} else if (player eq "5") {
// Flash 5 Player will execute this code.
getURL ("flash5.html");
}else { getURL ("flash6.html");
}
// We will prevent the movie from accidentally looping.
stop ();Note: if you want it just to show what kind of player you have, and not take you to a different file, you have to change the getURL() command to a _root.gotoAndStop() command that goes to a different frame inside the movie for each version of the player. By the way, don't forget to make those frames and add some words or graphics to each frame.
-------------------------
-------------------------
step 4:
Now you have to make the html files for each version of the player.
make a flash3.html, flash4.html, flash5.html, flash6.html.
what's inside these html files is of your own choice.
put them all in the same folder as the swf, the gif and the flashDetect.html
====================
====================
that's about all.
It does work. If you want to check it, go to http://www.migroup.go.ro/swiffer/scriptDetection.html
it will redirect you automatically to the page corresponding to the flash player you have.
