求助 VB 任务栏图标 不响应双击事件

[jageme]

最近在做一个软件.当然是自娱自乐为目的.
目的就想做一个类似QQ的登录界面.
然而,当我在做实现这个最小化到状态栏时,软件却不响应双击事件,不能还原,
一直不知道问题出在什么地方!有大神帮忙看一下

谢谢

Dim msg As Long
msg = X / Screen.TwipsPerPixelX
If msg = WM_LBUTTONDBLCLK Then '错误出在这里,,,双击事件不响应!
Me.WindowState = 0
Me.Show
Shell_NotifyIcon NIM_DELETE, Tray
End If

不行啊！！最小化后，我双击状态栏的图标没得反应哦！！

[jageme]

我靠．自己解决这个问题了，原因真他妈的不知道

我自己将from1这个窗体，删除后重新再建一个from1窗体，将代码和控件原封不去的复制过去，一切问题都解决了！
靠，
