VB6：你可以在工程里多建一个窗体， *** 作的菜单写在这里，不显示9 OK了
当你要的窗体关闭后 再+载托盘
VB.NET里直接9有Closing和Closed事件
以下9是托盘：

Dim TheForm As Form
Dim TheMenu As Menu

页面产生点击事件（例如button上bindtap的回调中）后才可调用，每次请求都会d出授权窗口，用户同意后返回userInfo。
每次通过该接口获取用户个人信息均需用户确认
wx.getUserProfile({
desc: '展示用户信息', // 声明获取用户个人信息后的用途
success: ({userInfo:{nickName,avatarUrl}}) =>{
// console.log(res)
// nickName 用户昵称，avatarUrl 用户头像图片地址
this.setData({
nickName,
avatarUrl,
flag:false
})
}
})
