vc 对话框启动隐藏到任务栏右侧的通知栏并交互操作

直接上代码吧

一 。对话框.h头文件

#define WM_TASKBAR WM_APP+1000 //1. 自定义消息句柄

class COnceDlg : public CDialog

{

// Construction

public:
void AddDelNotifyIcon(bool flag); //2.通知栏图标添加与删除
void ShowHide(bool flag); //3.窗体显示与隐藏
LRESULT OnTaskbar(WPARAM wParam, LPARAM lParam);//4.通知栏图标的交互函数

二。 在对话框.cpp实现文件中

在对话框.cpp实现文件完整的代码如下：

// onceDlg.cpp : implementation file

//

#include "stdafx.h"

#include "once.h"

#include "onceDlg.h"

#ifdef _DEBUG

#define new DEBUG_NEW

#undef THIS_FILE

static char THIS_FILE[] = __FILE__;

#endif
