Your Form in Sys Tray...

Ok, I have decided to post this in the code bank since I have been posting this in more then a few posts lately.

This code show you how to make your form show in the system tray using the Shell_NotifyIcon API.

Befor Using this code keep in mined that:

There is systray icon menu named "TrayMenu"
Exit button in that menu named "Ex"
A Show button in that menu named "Show"

I have attached the example file of this exact code for better help. Check bottom of my post.

VB Code:

Private Declare Function Shell_NotifyIcon Lib "shell32" Alias "Shell_NotifyIconA" (ByVal dwMessage As Long, pnid As NOTIFYICONDATA) As Boolean
'declaration for putting the application to system tray
Private Type NOTIFYICONDATA
    cbSize As Long
    hwnd As Long
    uId As Long
    uFlags As Long
    uCallBackMessage As Long
    hIcon As Long
    szTip As String * 64
End Type
 
    'declare constants
Private Const NIM_ADD = &H0
Private Const NIM_MODIFY = &H1
Private Const NIM_DELETE = &H2
Private Const WM_MOUSEMOVE = &H200
Private Const NIF_MESSAGE = &H1
Private Const NIF_ICON = &H2
Private Const NIF_TIP = &H4
 
'The following constants are used to determine the mouse input on the
 
    'Left-click
Private Const WM_LBUTTONDBLCLK = &H203   'Double click
Private Const WM_LBUTTONDOWN = &H201     'down
Private Const WM_LBUTTONUP = &H202       'up
 
    'Right-click
Private Const WM_RBUTTONDBLCLK = &H206   'Double click
Private Const WM_RBUTTONDOWN = &H204     'down
Private Const WM_RBUTTONUP = &H205       'up
 
'Dimension a variable as the user-defined data type.
Dim nid As NOTIFYICONDATA
 
 
Private Sub Ex_Click()
Unload Me
Shell_NotifyIcon NIM_DELETE, nid 'Delete the form's icon from the sys tray
End Sub
'   one main menu by Caption"Menu" name "TrayMenu"
'   one sub menu by name caption "Exit" name "Ex"
'   one sub menu by name caption "Show" name "Show"
 
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
            MsgBox "you clicked me!"
        '      Me.PopupMenu TrayMenu   'if u want u can call the popup menu
        Case WM_LBUTTONUP
        Case WM_LBUTTONDBLCLK
        Case WM_RBUTTONDOWN
        Case WM_RBUTTONUP
            Me.PopupMenu TrayMenu  'call the popup menu
        Case WM_RBUTTONDBLCLK
    End Select
End Sub
 
 
Private Sub Form_Resize()
If Me.WindowState = 1 Then
 
    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
        'u can give a tool tip text here
        nid.szTip = "My System Tray Message" & vbNullChar
       'Call the Shell_NotifyIcon function to add the icon to the System Tray, defulte form's icon
 
        Shell_NotifyIcon NIM_ADD, nid
        Else
End If
End Sub
 
Private Sub Show_Click()
Me.WindowState = 0
Me.Show
Shell_NotifyIcon NIM_DELETE, nid 'Delete the form's icon from the sys tray
End Sub
