Private Declare Function Shell_NotifyIcon Lib "shell32" Alias "Shell_NotifyIconA" (ByVal dwMessage As Long, pnid As NOTIFYICONDATA) As Boolean
Dim TrayI As NOTIFYICONDATA

' In Form Load

TrayI.cbSize = Len(TrayI)
TrayI.hwnd = pichook.hwnd 'Link the trayicon to this picturebox
TrayI.uId = 1&
TrayI.uFlags = NIF_ICON Or NIF_TIP Or NIF_MESSAGE
TrayI.uCallbackMessage = WM_LBUTTONDOWN
TrayI.hIcon = imgicon.Picture
TrayI.szTip = "Switch Notes" & Chr$(0)

'Create the icon

Me.Icon = imgicon.Picture
Shell_NotifyIcon NIM_ADD, TrayI

' i am having one imagebox(imgicon) and one picturebox ( pichook ) and taking imgicon's picture for picture box and using piturebox handle for tray icon's handle.
