Flex air执行Bat文件，打开关闭文件

RunFile.as文件，这个文件负责脚本打开文件，关闭文件操作，里面有调用Bat文件的操作，当然，也是通过NativeProcess类来实现的。
具体代码如下所示：

package com.floor.screen.redevelop.app
{
	import flash.desktop.NativeProcess;
	import flash.desktop.NativeProcessStartupInfo;
	import flash.filesystem.File;
	
	public class RunFile
	{
		//var file:File = new File(); 
		// 文件路径  
		//C:/Users/LONMID/Desktop/一卡通茶话会_一卡通.docx
		public var urlStr:String = "C:/Users/LONMID/Desktop/结网.pdf"; 
		public  var file:File ;
		public function RunFile()
		{
			file = new File(urlStr); 
		}
		
		public function openFile():void{
			file = new File(urlStr); 
			file.openWithDefaultApplication();
		}
		
		/**
		 * 关闭文件
		 **/ 
		public function closeFile():void{
			
//			file = new File("C:/Users/LONMID/Desktop/ccc.exe"); 
//			file.openWithDefaultApplication();
			var cmdFile:File=new File();
			cmdFile = cmdFile.resolvePath("C:/WINDOWS/system32/cmd.exe");
			var nativeProcessStartupInfo:NativeProcessStartupInfo = new NativeProcessStartupInfo();
			nativeProcessStartupInfo.executable = cmdFile;
			
			var processArgs:Vector.<String> = new Vector.<String>();
			processArgs[0] = "/c C:/Users/LONMID/Desktop/ccc.bat "; 
			//上面执行批处理的方式方法
			// C:/Users/LONMID/Desktop/ccc.bat
			
			nativeProcessStartupInfo.arguments=processArgs;
			var process:NativeProcess = new NativeProcess();
			
			process.start(nativeProcessStartupInfo); 


		}
		
	}
}
