saving data to file

[velanse]

Hi

I am loading variables in my application using LoadVars in Actionscript from simple html file.
And I need to save these variables back to this html file after changing. Is there any posibility to do this via SWFkit and how can I do this?

Thanks in advance!

Do you mean saving the variables to a local disk file or sending them back to the remote html file? If former, you can use the FileStream or DataFile object in swfkit; if latter, you can use the "LoadVars" object in actionscript.

I mean saving data to a local disk file. So I tried to use FileStream object:

stream = new FileStream("data.html", "w+" );
stream.writeLine("&header1="+_root.data_lv.header);
....
stream.close();

It looks like everything works fine. BUT I faced another problem: This method saves data in "Windows" encoding and LoadVars object reads variables in UTF-8 encoding... So my program can not read them after saving...

Is there any posibility to change encoding of FileStream???

The following code shows how to use the "toUTF8" method (ffish script method) to write a XML file

//convert a string to an utf8 encoded string stream
function toUTF8(string)
{
var i;
var stream = new StringStream;

for (i = 0; i < string.length; i++)
{
var code = string.charCodeAt(i);

if (code < (1 << 7))
{
stream.put(code);
}
else if (code < (1 << 11))
{
stream.put((code >> 6) | 0xC0);
stream.put((code & 0x3F) | 0x80);
}
else if (code < (1 << 16))
{
stream.put(0xE0 | ((code >> 12) & 0x0F));
stream.put(0x80 | ((code >> 6) & 0x3F));
stream.put(0x80 | (code & 0x3F));
}
else if (code < (1 << 21))
{
stream.put((code >> 18) | 0xe0);
stream.put(((code >> 12) & 0x3f) | 0x80);
stream.put(((code >> 6) & 0x3f) | 0x80);
stream.put((code & 0x3f) | 0x80);
}
}

return stream;
}

var str = '<project name="test" default="init" basedir=".">' +
'     <target name="init">' +
'          <!-- displays Hello in Chinese -->' +
'          <echo message="The Chinese word is: ÊÀ¼Í"/>' +
'     </target>' +
'</project>';

var f = new FileStream("c:\\1.xml", "w");
f.writeLine('<?xml version="1.0" encoding="UTF-8"?>');
f.write(toUTF8(str));
f.close();
