给你一段代码参考一下

'删除系统栏的拖盘
Call Shell_NotifyIcon(NIM_DELETE, TrayIcon)
End Sub

Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
On Error Resume Next
Dim Message As Long

Message = X / Screen.TwipsPerPixelX

'判断鼠标消息,执行不同的功能
Select Case Message
Case WM_LBUTTONDOWN
'点击拖盘
Case WM_RBUTTONUP

'按右键弹出菜单
'PopupMenu mnuPopup
End Select
End Sub

Private Sub Timer1_Timer()
bolFlag = Not bolFlag

TrayIcon.cbSize = Len(TrayIcon)
TrayIcon.hWnd = hWnd
TrayIcon.uId = vbNull
TrayIcon.uFlags = NIF_ICON Or NIF_TIP Or NIF_MESSAGE
TrayIcon.ucallbackMessage = WM_MOUSEMOVE
TrayIcon.hIcon = IIf(bolFlag, Me.Icon, Picture1.Picture)
TrayIcon.szTip = "拖盘" & Chr(0)

'在系统栏添加拖盘
Call Shell_NotifyIcon(NIM_MODIFY, TrayIcon)
End Sub

实现的方法系统拖盘
1。如楼上，直接用api放到模块
2。用现成控件
