End Sub
Private Sub Form_Load ()
Center_This_Form Me
End Sub

uFlags As Long
uCallBackMessage As Long
hIcon As Long
szTip As String * 64
End Type
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
Private Const WM_LBUTTONDBLCLK = &H203 'Double-click
Private Const WM_LBUTTONDOWN = &H201 'Button down
Private Const WM_LBUTTONUP = &H202 'Button up
Private Const WM_RBUTTONDBLCLK = &H206 'Double-click
Private Const WM_RBUTTONDOWN = &H204 'Button down
Private Const WM_RBUTTONUP = &H205 'Button up
Private Declare Function Shell_NotifyIcon Lib "shell32" Alias "Shell_NotifyIconA" (ByVal dwMessage As Long, pnid As NOTIFYICONDATA) As Boolean
Dim nid As NOTIFYICONDATA
Private Sub Command1_Click ()
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
nid.szTip = "Taskbar Status Area Sample Program" & vbNullChar
Shell_NotifyIcon NIM_ADD, nid
End Sub
Private Sub Command2_Click ()
Shell_NotifyIcon NIM_DELETE, nid
End Sub
Private Sub Form_Load ()
Command1.Caption = "Add an Icon "
Command2.Caption = "Delete Icon "
End Sub
Private Sub Form_Resize ()
If form1.WindowState = vbMinimized Then
Call Command1_Click
Me.Visible = False
End If
End Sub
Private Sub Form_Terminate ()
Shell_NotifyIcon NIM_DELETE, 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
Case WM_LBUTTONUP
Me.WindowState = vbNormal
Me.Visible = True
Me.SetFocus
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 ")
If ToolTipString <> "" Then
nid.szTip = ToolTipString & vbNullChar
Shell_NotifyIcon NIM_MODIFY, nid
End If
Case WM_RBUTTONUP
Case WM_RBUTTONDBLCLK
End Select
End Sub
3 . استفاده از progressbar
Private Sub Command1_Click ()
For a = 1 To 20000
p1.Value = a
Next a
Form2.Show
End Sub
4. باز كردن پنجره اينترنت اكسپلور از داخل برنامه
اين كد را در قسمت Form / General بنويسيد
( Private Sub OpenUrl (URLName As String
Dim objIE As Object
(" Set objIE = CreateObject ("internetexplorer.application
objIE.Visible = True
(( objIE.Navigate (Trim(URLName
End Sub
( ) Private Sub cmdGO_Click
( Call OpenUrl (txtURLName
End Sub
5 . باز و بستن درب CD ROM
Public Declare Function mciSendString Lib "winmm.dll" Alias "mciSendStringA" (ByVal lpstrCommand As String, ByVal lpstrReturnString As String, ByVal uReturnLength As Long, ByVal hwndCallback As Long) As Long
Private Sub CMDOPEN_Click ()
