# aardio 范例: 窗口自动化 - 入门



```aardio
//窗口自动化 - 入门
import winex.key;
import process;

//运行写字板
if( !process.executeWaitInput("wordpad.exe") ){
	error("系统未安装写字板");
}

//查找并等待激活的窗口
var hwnd,hCtrl = winex.waitActive(,,"WordPadClass","RICHEDIT50W"); 

//win.setFocus,winex.key.combine 等必须要绑定到目标输入线程
winex.attach(hwnd,function(){
	
	//设置焦点
	win.setFocus(hCtrl)
	
	//输入一些内容 (你知道aardio发送文本的方式共有多少种吗?)
	winex.key.send(hCtrl,"Test" )
	thread.delay(100)
	
	//后台发送CTRL+A组合键 
	winex.key.combine(hwnd,"CTRL","A")
	
	//后台发送ALT+F组合键
	winex.key.altClick(hwnd,"F" )
})
