Flex Air 周边整合之碎语

手边近期有一个项目（薪酬系统）要开工，开始用Flex Air打理框架

1、Flex Air 依然作为本地前台；
2、中介语言不再采用php(amfphp),java(lds)或c#(FluorineFx)来搞了,直接采用assql;
3. 数据库采用远程数据库Mysql

[Note]
1.由于涉及远程数据库，所以用C++编辑Mysql联机参数，再采用Alchemy编译成swc来封装

//MySqlService.cpp

#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include "AS3.h"

AS3_Val GetMysqlArg(void* self, AS3_Val args)
{

	char* val = NULL;
        //本机
	AS3_Val localconn = AS3_Object("host:StrType,port:StrType,username:StrType,password:StrType,database:StrType","127.0.0.1","3306","xxxxx", "xxxx","xxxxx");
	//网络
        AS3_Val netconn = AS3_Object("host:StrType,port:StrType,username:StrType,password:StrType,database:StrType","xxx.xxx.xx.xx","3306","xxxxx", "xxxx","xxxx");
	
	AS3_ArrayValue( args, "StrType", &val );
	if(val == NULL)
	{
		return localconn;
	}
	
	return netconn;
	
}

int main()
{
	AS3_Val cMethod = AS3_Function( NULL, GetMysqlArg);
	AS3_Val result = AS3_Object("GetMysqlArg: AS3ValType",cMethod);
	AS3_Release(cMethod);
	AS3_LibInit( result );
	
	return 0;
}

 

//主程式运用

var cppMySqlService:CLibInit=new cmodule.mysqlservice.CLibInit;
	var mysqlArgObj:Object=cppMySqlService.init();
	//与远程数据库联机
	var mysqlServie:Object=mysqlArgObj.GetMysqlArg("net");
	SQLGlobal.set_mysql_host(mysqlServie.host);
	SQLGlobal.set_mysql_port(int(mysqlServie.port))
	SQLGlobal.set_mysql_username(mysqlServie.username)
	SQLGlobal.set_mysql_password(mysqlServie.password)
	SQLGlobal.set_mysql_database(mysqlServie.database)

2.由于项目又要涉及windows的相关操作，如调用.dll(FluorineFx Aperture framework)等并且还有考虑到以后软件的自动更新，所以在前期得将程序以exe包形式发布，由于air官方不支持exe包的自动更新，所以采用了nativeApplicationUpdater来处理，这样既兼顾了自动更新，也兼顾了与本地系统的API的交互；

protected function isNewerFunction(currentVersion:String, updateVersion:String):Boolean
{
	if (currentVersion == updateVersion)
	{
		trace("版本一样,直接进入平台")
		DoShowLogin()
	}
	else
	{
		trace("版本不一样")
		//提示用户是否更新
		Alert.show("软件有新的更新:版本(" + updater.updateVersion + ").下载安装更新吗?", "提示信息", 3, null, versionCloseHandler, null, 3)
	}
	return true;
}

private function versionCloseHandler(event:CloseEvent):void
{
	if (event.detail == Alert.YES)
	{
		trace("更新");
		doGoUpdate()
	}
	else
	{
		//客户不更新，直接登陆界面
		DoShowLogin()
	}
}

protected function doGoUpdate():void
{

	doCreateDownloadingView()
	updater.addEventListener(DownloadErrorEvent.DOWNLOAD_ERROR, updater_downloadErrorHandler);
	updater.addEventListener(UpdateEvent.DOWNLOAD_COMPLETE, updater_downloadCompleteHandler);
	updater.downloadUpdate();
}

private function doCreateDownloadingView():void
{
	
	//清空对象，创建下载更新包自定义界面
	MainAppContainer.removeAllChildren();

	var viewHGroup:HGroup=new HGroup();
	viewHGroup.setStyle("horizontalCenter", 0)
	viewHGroup.setStyle("verticalCenter", 0);
	viewHGroup.setStyle("verticalAlign", "top");
	MainAppContainer.addChild(viewHGroup)
	
	var bitmapImg:BitmapImage=new BitmapImage();
	bitmapImg.source='/assets/system_upgrade.png';
	viewHGroup.addElement(bitmapImg)
	
	var viewVGroup:VGroup=new VGroup();
	viewVGroup.percentWidth=100;
	viewVGroup.setStyle("horizontalAlign", "center")
	viewHGroup.addElement(viewVGroup)
	
	var infoLabel:Label=new Label();
	infoLabel.text="更新说明："
	viewVGroup.addElement(infoLabel)
	
	var richTxt:RichText=new RichText();
	richTxt.text=updater.updateDescription;
	viewVGroup.addElement(richTxt);
	
	var prgBar:ProgressBar=new ProgressBar();
	prgBar.label="下载中... %3%";
	prgBar.source=updater;
	viewVGroup.addElement(prgBar);
}

protected function updater_errorHandler(event:ErrorEvent):void
{
	Alert.show(event.text);
}
protected function updater_initializedHandler(event:UpdateEvent):void
{
	trace("初始化毕，执行检查")
	updater.checkNow();
}
protected function updater_updateStatusHandler(event:StatusUpdateEvent):void
{
	if (event.available)
	{
		event.preventDefault();
	}
	else
	{
		Alert.show("Your application is up to date!");
	}
}
private function updater_downloadCompleteHandler(event:UpdateEvent):void
{
	trace("下载完成")
	updater.installUpdate();
}

private function updater_downloadErrorHandler(event:DownloadErrorEvent):void
{
	Alert.show("下载更新安装包出错，请稍候再试！");
}

/******************************************************************************/
public function DoShowLogin():void
{
	trace("显示登陆界面")
	this.stage.nativeWindow.visible=false
	var logoWin:LoginWindow=new LoginWindow()
	logoWin.open(true)
	logoWin.nativeWindow.x=Capabilities.screenResolutionX / 2 - logoWin.width / 2;
	logoWin.nativeWindow.y=Capabilities.screenResolutionY / 2 - logoWin.height / 2;
}

3.每一个控制单元仍然采用module来处理，本想采用常态的模式*.mxml来作界面，as编写操练，写了两三个模块单元，每次切换到Design模式，Adobe他爷爷，哇卡卡,最后还是把这个转换成全as,本想偷点懒，不想，还更花时间和精力。以后再也不想用尝试mxml(界面)+as(操纵)的方式,还有继续用全as来实现。卡死我了！

4.Tlf这么久了，还没有明显进步，Text Layout Framework Team，why!!!!!!!!!!!!，难道非得要第三方来编写TableElement,CodeElement，MediaElement吗?
