首先在formload里加入以下代码:MyProc = SetWindowLong(Me.Hwnd, GWL_WNDPROC, AddressOf WindowProc)
ShowTray me.hwnd,Picture1,"hello"其次定义windowproc
Private Function WindowProc(ByVal Hwnd As Long, ByVal msg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
Dim ret As Long
'实现窗体的拖动
If msg = WM_NCHITTEST Then
ret = DefWindowProc(Hwnd, msg, wParam, lParam)
If ret = HTCLIENT Then
WindowProc = HTCAPTION
Else
WindowProc = ret
End If
'将其他的消息传给默认的窗口函数进行处理
Else
If msg = WM_SYSCOMMAND And wParam = SC_MINIMIZE Then
frmEmail.Visible = False
Else
WindowProc = CallWindowProc(MyProc, Hwnd, msg, wParam, lParam)
End If
End If
End Function'加入代码托盘
Private Sub ShowTray(myhwnd, IconPic As PictureBox, Optional tip As String = "")
'sets cbSize to the Length of TrayIcon
TrayIcon.cbSize = Len(TrayIcon)
' Handle of the window used to handle messages - which is the this form
TrayIcon.Hwnd = myhwnd
' ID code of the icon
TrayIcon.uID = vbNull
' Flags
TrayIcon.uFlags = NIF_ICON Or NIF_TIP Or NIF_MESSAGE
' ID of the call back message
TrayIcon.uCallbackMessage = WM_MOUSEMOVE
' The icon - sets the icon that should be used
TrayIcon.hIcon = IconPic.Picture
' The Tooltip for the icon - sets the Tooltip that will be displayed
TrayIcon.szTip = tip & Chr$(0)
' Add icon to the tray by calling the Shell_NotifyIcon API
'NIM_ADD is a Constant - add icon to tray
Call Shell_NotifyIcon(NIM_ADD, TrayIcon)
' Don't let application appear in the Windows task list
App.TaskVisible = FalseEnd Sub
ShowTray me.hwnd,Picture1,"hello"其次定义windowproc
