Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
Dim lMsg As Single
lMsg = X / Screen.TwipsPerPixelX
If lMsg = WM_LBUTTONUP Then
Me.WindowState = 0
Me.Show
End If
End Sub
在窗体添加WebBrowser1后能托最小化，但点击图标窗体不能还原到桌面

Answer 1

Form_MouseMove过程好像有点问题，试试把这个过程换成下面的这个过程代码

Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
Dim lMsg As Single
lMsg = X / Screen.TwipsPerPixelX
Select Case lMsg
Case WM_LBUTTONUP
'单击左键，显示窗体
'ShowWindow Me.hWnd, SW_RESTORE
'Timer1.Enabled=false
'下面两句的目的是把窗口显示在窗口最顶层
Me.Show
Me.SetFocus
MsgFlag = False
SetIcon (CreatTip)
'' Case WM_RBUTTONUP
'' PopupMenu MenuTray '如果是在系统Tray图标上点右键，则弹出菜单MenuTray
'' Case WM_MOUSEMOVE
'' Case WM_LBUTTONDOWN
'' Case WM_LBUTTONDBLCLK
'' Case WM_RBUTTONDOWN
'' Case WM_RBUTTONDBLCLK
'' Case Else
End Select
End Sub
