Dim nid As NOTIFYICONDATA
Sub minimize_to_tray()
Me.Hide
nid.cbSize = Len(nid)
nid.hwnd = Me.hwnd
nid.uId = vbNull
nid.uFlags = NIF_ICON Or NIF_TIP Or NIF_MESSAGE
nid.uCallBackMessage = WM_MOUSEMOVE
nid.hIcon = Me.Icon
nid.szTip = "blablabla text u want to show when mouse over tray iicon" & vbNullChar
Shell_NotifyIcon NIM_ADD, nid
End Sub
Private Sub Form_MouseMove(Button As Integer, Shift As Integer, x As Single, y As Single)
Dim msg As Long
Dim sFilter As String
msg = x / Screen.TwipsPerPixelX
Select Case msg
Case WM_LBUTTONDOWN
Me.Show
Shell_NotifyIcon NIM_DELETE, nid
