System Tray

[Vec]

I need to make a form minimize to the sys tray and disappear from the task bar, when the user double or single clicks (either one) on the sys tray icon, the form shows and the sys tray icon disappears.

It is for an mp3 player I am working on, it is only one form so hopefully it isn't to hard to do this. The form name is frmPlayer -

DO the following steps:

'Insert one Form And Menu Named mPopupSys


'IN FORM Load Event


Private Sub Form_Load()

With nid
.cbSize = Len(nid)
.Hwnd = Me.Hwnd
.uId = vbNull
.uFlags = NIF_ICON Or NIF_TIP Or NIF_MESSAGE
.uCallBackMessage = WM_MOUSEMOVE
.hIcon = Me.Icon
.szTip = "Smaller one" & vbNullChar
End With

Shell_NotifyIcon NIM_MODIFY, nid

End Sub

'In Form Mouse_Move event insert following code

Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
'this procedure receives the callbacks from the System Tray icon.
