Loading variables into a Flash movie

Worfolk Desktop News was an application which downloaded the latest news from Worfolk and displayed it in the application. The original application was built in flash and loaded the variables in from a text file stored on the Worfolk servers.

The text file was simple:

news=the news story...

Create a text file like this and upload it somethere, or even just leave it on your hard drive as long as you know the file path. Now to load it into the flash movie you use LoadVariables. Go to the first frame in your movie and go into actionscript. Now add a LoadVariables command and add in the url path or file path to your text file.

Once this is done you have the variables stored in your movie. Next create a text area and set it to dynamic text. Where it says “var” and has a space to enter a name such as “news,” or whatever name you gave your variable in the text file.

Now run your movie. If it worked right the text area should now display the value you have the variable. If you copied my text into your text file you should come out with “the news story…” If its blank you have probably given the wrong url or you have got different names for the variable in your text file then you do in your movie.

Using Request in ASP

The request function, suprising requests a value. This could be a query string, form variable, or some other value. For example if you were at the following URL.

http://www.somepage.com/home.asp?ID=23

And you had a script as such.

Request.QueryString("ID")

The call would return the value 23.

An example of where this can be used is on the M World News channel. The news is stored dynamically in a databasde so when you click on a link to the full story from the news homepage you are taken to a dynamic page which selects the story based on the ID of the story you want passed to the page as a url variable. For example the link could be:

http://www.mworld.us/news/story.asp?ID=52

Examples of use:

Request.QueryString("SomeURLVariable")
Request.Form("SomeFormElement")
Request.Cookies("SomeCookie")

Query strings not detected in ASP

Problem: You are requesting QueryString’s in ASP but nothing happens and the value seems to be empty.

Cause: You cannot use default documents when requesting QueryString’s. For example:

http://www.somefile.com/search/index.asp?q=hello

Would pick up that the query string “q” is set to “hello.” However:

http://www.somefile.com/search/?q=hello

Would not pick up anything despite index.asp being loaded as the default document.

Fix: Enter the full url instead of skipping out the file name.

ASP Request function

The request function, surprisingly, requests a value. This could be a URL variable, form variable, or some other value. For example if you were at the url.

http://www.somepage.com/home.asp?ID=23

You would use the following code in your script.

Request.QueryString("ID")

The line would then return the value 23.

An example of where this can be used is on the M World News channel. The news is stored dynamically in a database so when you click on a link to the full story from the news homepage you are taken to a dynamic page which selects the story based on the ID of the story you want passed to the page as a url variable. For example the link could be as follows.

http://www.mworld.us/news/story.asp?ID=52

Examples of use

Request.QueryString("SomeURLVariable")
Request.Form("SomeFormElement")
Request.Cookies("SomeCookie")
