pass parameter in flex NativeProcess - actionscript-3

Question

I want to pass two parameter to nativeProcess.
While i am running exe file using windows command with parameter, it is working.
Command for window is "abc.exe a.txt b.txt"
How can I pass two parameters to the exe in that format using flex nativeProcess?
This is what I have so far:
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx" applicationComplete="windowedapplication1_applicationCompleteHandler(event)">
<fx:Script>
<![CDATA[
import mx.events.FlexEvent;
private var process:NativeProcess;
protected function windowedapplication1_applicationCompleteHandler(event:FlexEvent):void
{
if (NativeProcess.isSupported)
{
callExe();
}
else
{
textReceived.text = "NativeProcess not supported.";
}
}
public function callExe():void
{
var a_FilePath:String = File.applicationStorageDirectory.resolvePath("dist/a.txt").nativePath;
var b_FilePath:File = File.applicationStorageDirectory.resolvePath("dist/b.txt").nativePath;
if (Capabilities.os.toLowerCase().indexOf("win") > -1)
{
var file:File = File.applicationStorageDirectory.resolvePath("dist/abc.exe");
}
var nativeProcessStartupInfo:NativeProcessStartupInfo = new NativeProcessStartupInfo();
// i put the line below and it works in my case
nativeProcessStartupInfo.workingDirectory = File.applicationStorageDirectory.resolvePath();
nativeProcessStartupInfo.executable = file;
var args:Vector.<String> = new Vector.<String>();
args.push(a_FilePath);
args.push(b_FilePath);
nativeProcessStartupInfo.arguments = args;
process = new NativeProcess();
process.start(nativeProcessStartupInfo);
process.addEventListener(ProgressEvent.STANDARD_OUTPUT_DATA, onOutputData);
process.addEventListener(ProgressEvent.STANDARD_INPUT_PROGRESS, inputProgressListener);
process.addEventListener(ProgressEvent.PROGRESS, progressEvent);
process.addEventListener(ProgressEvent.STANDARD_ERROR_DATA, errorData);
}
public function inputProgressListener(event:ProgressEvent):void
{
textReceived.text += "Input Progress Event";
}
public function onOutputData(event:ProgressEvent):void
{
textReceived.text += "Output Event";
}
public function progressEvent(event:ProgressEvent):void
{
textReceived.text += "Progress Event";
}
public function errorData(event:ProgressEvent):void
{
textReceived.text += "Error Event";
}

I solved my puzzle by adding the line below in bold:
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"

{
textReceived.text = "NativeProcess not supported.";
}
}
public function callExe():void
{
var a_FilePath:String = File.applicationStorageDirectory.resolvePath("dist/a.txt").nativePath;
var b_FilePath:File = File.applicationStorageDirectory.resolvePath("dist/b.txt").nativePath;
if (Capabilities.os.toLowerCase().indexOf("win") > -1)
{
var file:File = File.applicationStorageDirectory.resolvePath("dist/abc.exe");
}
var nativeProcessStartupInfo:NativeProcessStartupInfo = new NativeProcessStartupInfo();
// i put the line below and it works in my case
nativeProcessStartupInfo.workingDirectory = File.applicationStorageDirectory.resolvePath();
nativeProcessStartupInfo.executable = file;
var args:Vector.<String> = new Vector.<String>();
args.push(a_FilePath);
args.push(b_FilePath);
nativeProcessStartupInfo.arguments = args;
process = new NativeProcess();
process.start(nativeProcessStartupInfo);
process.addEventListener(ProgressEvent.STANDARD_OUTPUT_DATA, onOutputData);
