Javascript to read txt file

Hello Dave,

To read a text file, I use java function :

//Read a file located in the script category
var fl = Context.getFile("area.txt", Constants.LOCATION_SCRIPT);
var fstream = new java.io.ByteArrayInputStream(fl);
var inputstream = java.io.DataInputStream(fstream);
var bufferReader = java.io.BufferedReader(new java.io.InputStreamReader(inputstream));
var strLine = "";
var totalLines = "";
while((strLine = bufferReader.readLine()) != null){
    totalLines += strLine;
}

I hope it can help.

Best Rgards

Thank you for your help. I input the code. Why would I get an error - Java constructor for "java.io.ByteArrayInputStream" with arguments .... not found"?

Hello, the argument must be a buffer array of byte.

Do not pass in parameter the selected file you get with the :

Dialogs.getFilePath("","*.txt","C:\Users","Select File",0);

I think you should pass a byte Array :

var byteArray = selFiles[0].getData();

var fstream = java.io.ByteArrayInputStream(byteArray);

Let me know if it works.

Best Regards.

Thank you for your help. I was able to find an example in the scripts supplied with the distribution disk that helped me. The code below is working for me and is very similar to the code you have.

function readTextFile(){

    var selFiles = Dialogs.getFilePath("","*.txt","C:\Users","Select the Master Matrix Data File",0);   

    var inStream   = new java.io.ByteArrayInputStream(selFiles[0].getData());

    var fileReader = new java.io.InputStreamReader(inStream);     

    var bufReader  = new java.io.BufferedReader(fileReader);

    var strLine="";

    var totalLines="";

    while((strLine=bufReader.readLine())!=null){

        totalLines+=strLine;

    }

    return totalLines;

}
