how do you read in string variables from a txt file, and display this in a text box, so that the variables may be of use later.

Welcome, man.  
Check the tutes. There’s one about scrolling imported text that shows how you can do that.

thanks for the reply, but the thing is :-  
lets say i have an output text box called “outFile”, it requires me to use “outFile=hello&”, within the text file itself, is there any way of getting around this where i dont need to use “outFile=”.

Well, yeah, read the tute, kid. You use a loadVars object, and you can do whatever you like in the onLoad.

sorry i didnt make myself clear, i read the tutorials and used loadVariables(url,target)  
but it seems that the actually content of the file is required to consist of an assignment of the target variable.  
outFile= …&  
what do you mean by using the onLoad as it only returns a boolean value.

so you want to be able to load an external txt file without it containing **thisTEXT=“content”**??? If so… Um, may I ask why?

Peace

// not loadVariables, loadVars

// err… WHA’?\*\*  
The tute: [http://www.kirupa.com/developer/mx/dynamic\_scroller.asp](http://www.kirupa.com/developer/mx/dynamic_scroller.asp)

The idea:

```auto
loadText = new loadVars();
loadText.load("kirupa.txt");
//creating the loadVarsText object and load function
loadText.onLoad = function() {
	// the variable container in the text is called Kirupatext
	// but you retrieve it as scroller.text.
	scroller.text = this.kirupatext;
};

```

Is that what you are trying to do?

yeah thanks K, i found and used :-  
function fileRead() {

```
loadVarsText = new loadVars();
loadVarsText.load("textfile.txt");
loadVarsText.onLoad = function() {
	outFile=loadVarsText;
};

```

}

but i get:-

there%20%20was%20a%20young%20man%20from%20downducket%20with%20a%20bob&onLoad=%5Btype%20Function%5D

from the text: "there was a young man from downducket with bob. "  
What is all that other stuff in between, and the text added onto the end, something to do with onload.

Strange. Use unescape:

```auto
a="there%20%20was%20a%20young%20man%20from%20downducket%20with%20a%20bob&onLoad=%5Btype%20Function%5D"
trace (unescape(a));

```

It seems to insert information about the onload[type function] to the end of the string, which i dont want. how do i stop this happening.

Try this:

myFile = new LoadVars();  
myFile.onData = function(rawDataFromMyFile){  
myText = unescape(rawDataFromMyFile);  
}  
myFile.load(“myTextFile.txt”);

That’ll override the normal onData handler (which overrides the procedures that look for variable/data pairs in your file) and simply drop the raw text data (minus escape characters) into the variable: myText.

You may want to put the following line after all that to un-override the onData method for the myFile object if you want to load other files in the usual way (with variable/data pairs).

delete myFile.onData;

Cheers.

You need to put:

myFile = new LoadVars();  
myFile.onData = function(rawDataFromMyFile){  
outFile = unescape(rawDataFromMyFile);  
}  
myFile.load(“textfile.txt”);

Why not use xml?

```php
myXML = new XML();
myXML.onLoad = function (success) {
   if (success){
      trace ("loaded successfully");
      myTextBox.text = unescape(myXML);
   }else{
      trace("Error Loading Specified File");
   }
}
myXML.load ("Textfile.txt");

```

onData does work, but using the way above, you get the error checking feature integrated with hassle-free loading.
