Problem passing variables from asp to flash (load object)

Hi all,

I'm creating a website that needs to read some urls from a database into flash, and so I decideded to use asp and access 2007.

At the moment everything works when I do dummy runs:

>Asp gets the information form the database and prints out to a window
>Flash takes the urls from a text file and adds it to some buttons.

This would all be good and well if thats what I needed for my app to work, but the problem is that the movie should be reading the urls from the window which the asp file outputs.

I've used

Code:

countryInfo.load("http://127.0.0.1:8180/database_2.asp",countryInfo,"GET");

Which goes to the url in arg 1 to read the info into the load object (arg2). Arg 3 is just the type of loading ( to post variables to another place or get them from a place).

There are no errors and I tested this function using:

Code:

countryInfo.onLoad = function(success:Boolean):Void
{
    if (success) 
    {
        trace(countryInfo.toString());
                 }
    else
                {
                                //outputs if cant connect to database
                                trace("Error connecting to server.");
                 }

Which after a few debugging runs printed out success so I know it connects to the asp file.

However...the urls didnt go to my buttons so I converted the loading object into a string in flash (using countryInfo.tostring()) so that I could see what was being sent back, and I tested the flash file with a text file then the asp file to make sure.

I have different outputs for the text file (which works) to the web file (which doesnt)...

The load object from the text file looks like this:

ausUrl=null&onLoad=%5Btype%20Function%5D

and the web one looks like this:

%0D%0A%0D%0AausUrl=null%20%20%0D%0A%20%20&onLoad=%5Btype%20Function%5D

I think the problem is that the flash file cant read the variable from the web load object (underlined). This is because the flash looks for a matching variable name, separating the name from the value using '=' and separating each variable from another using '&'.

In the text load object its easy cos the variables are formatted correctly and so flash evaluates a match, but in the web load object has all of this %0D%0A%0D%0A noise which I dont know how to omit...

If I cant get rid of that then flash assumes its all part of the variable name on the left side of the '=' and that on the right ( before the '&') its the value.

So if Im looking for a match for ausUrl=null I wont get it because its like this:

%0D%0A%0D%0AausUrl=null%20%20%0D%0A%20%20

how does one get rid of the noise??

Any help much appreciated as my boss is breathing down my neck

Hi to anyone who was reading i figured out what was wrong:

When you send a variable to flash from asp you need to use the Response.Write method.

The problem was that flash must read data from an external file in a certain format

I was getting lots of %%% because I needed to put an '&' infront of the variable that I sent from the asp file like this :

1) response.write "&variable=" & var1

but I wrote it in the asp file like this:

2) response.write "variable=" & var1

Doing this (1) gets rid of all of the %%% business because flash reads the '&' as an indicator to the next variable.

Hope that was useful for anyone having the same probs
