Steps To Create Sample Program
Start Visual Basic. If it is already running, go to the File menu and click New Project.
Place two CommandButtons and a common dialog box control on Form1.
Copy the following code to the Form1 code window:
'Declare a user-defined variable to pass to the Shell_NotifyIcon
'function.
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 the constants for the API function. These constants can be
'found in the header file Shellapi.h.
'The following constants are the messages sent to the
'Shell_NotifyIcon function to add, modify, or delete an icon from the
'taskbar status area.
Private Const NIM_ADD = &H0
Private Const NIM_MODIFY = &H1
Private Const NIM_DELETE = &H2
'The following constant is the message sent when a mouse event occurs

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
'the icon in the taskbar status area.
'Left-click constants.
Private Const WM_LBUTTONDBLCLK = &H203 'Double-click

'Right-click constants.
Private Const WM_RBUTTONDBLCLK = &H206 'Double-click

'Dimension a variable as the user-defined data type.
Dim nid As NOTIFYICONDATA
Private Sub Command1_Click()
'Click this button to add an icon to the taskbar status area.
'Set the individual values of the NOTIFYICONDATA data type.
nid.cbSize = Len(nid)
nid.hWnd = Form1.hWnd
nid.uId = vbNull
nid.uFlags = NIF_ICON Or NIF_TIP Or NIF_MESSAGE
nid.uCallBackMessage = WM_MOUSEMOVE
nid.hIcon = Form1.Icon

'Call the Shell_NotifyIcon function to add the icon to the taskbar
'status area.
Shell_NotifyIcon NIM_ADD, nid
End Sub
Private Sub Command2_Click()
'Click this button to delete the added icon from the taskbar
'status area by calling the Shell_NotifyIcon function.
Shell_NotifyIcon NIM_DELETE, nid
End Sub
Private Sub Form_Load()
'Set the captions of the command button when the form loads.
Command1.Caption = "Add an Icon"
Command2.Caption = "Delete Icon"
End Sub
Private Sub Form_Terminate()
'Delete the added icon from the taskbar status area when the
'program ends.
Shell_NotifyIcon NIM_DELETE, nid
End Sub
Private Sub Form_MouseMove _
(Button As Integer, _
Shift As Integer, _
X As Single, _
Y As Single)
'Event occurs when the mouse pointer is within the rectangular
'boundaries of the icon in the taskbar status area.
Dim msg As Long
Dim sFilter As String
msg = X / Screen.TwipsPerPixelX
Select Case msg
Case WM_LBUTTONDOWN
Case WM_LBUTTONUP
Case WM_LBUTTONDBLCLK
CommonDialog1.DialogTitle = "Select an Icon"
sFilter = "Icon Files (*.ico)|*.ico"
sFilter = sFilter & "|All Files (*.*)|*.*"
CommonDialog1.Filter = sFilter
CommonDialog1.ShowOpen
If CommonDialog1.filename <> "" Then
Form1.Icon = LoadPicture(CommonDialog1.filename)
nid.hIcon = Form1.Icon
Shell_NotifyIcon NIM_MODIFY, nid
End If
Case WM_RBUTTONDOWN
Dim ToolTipString As String
ToolTipString = InputBox("Enter the new ToolTip:", _
"Change ToolTip")
