在vc 6.0里要给托盘增加气球提示的确要费一番工夫
首先要到下面
http:www.microsoft.com/msdownload/platformsdk/sdkupdate/XPSP2FULLInstall.htm
下载新的sdk进行安装
安装之后,还要把这个新的sdk和visual studio关联起来
在开始菜单里有这样一个菜单项.手工关联的话,比较麻烦,这里就不说了
剩下的使用方法请看下面的注释

#define _WIN32_IE 0x0501    //必须定义这个,NOTIFYICONDATA的某些属性才可用
#define WM_TRAYMESSAGE WM_USER + 1 //我托盘图标相关的消息
#include <windows.h>
#include <shellapi.h>    //Shell_NotifyIcon
#include "resource.h"

//过程函数的返回值都是LRESULT,类型都是CALLBACK
