学习了下后台，主要部分没什么，主要是自制标题栏和后台托盘，这里给出这两个关键部分
’托盘
Private Declare Function Shell_NotifyIcon Lib "shell32.dll" (ByVal dwMessage As Long, lpData As NOTIFYICONDATA) As Long
Const NIM_ADD = &H0
Const NIM_DELETE = &H2
Const NIF_ICON = &H2
Const NIF_MESSAGE = &H1
Const NIF_TIP = &H4
Const WM_MOUSEMOVE = &H200
Const WM_LBUTTONDBLCLK = &H203
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
Dim tray As NOTIFYICONDATA
Private Sub Command1_Click()
tray.cbSize = Len(tray)
tray.uId = vbNull
tray.hWnd = Me.hWnd
tray.uFlags = NIF_TIP Or NIF_MESSAGE Or NIF_ICON
tray.uCallBackMessage = WM_MOUSEMOVE
tray.hIcon = Me.Icon
tray.szTip = "测试" & vbNullChar
Shell_NotifyIcon NIM_ADD, tray
Me.Hide
End Sub
Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
Dim msg As Long
msg = X / 15
If msg = WM_LBUTTONDBLCLK Then
Me.Show
Shell_NotifyIcon NIM_DELETE, tray
End If
End Sub
拖动Private Declare Function ReleaseCapture Lib "user32" () As Long
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Long) As Long
Const HTCAPTION = 2
Const WM_NCLBUTTONDOWN = &HA1
Private Sub Form_MouseDown(Button As Integer, Shift As Integer, x As Single, Y As Single)
If Button = 1 Then
Dim ReturnVal As Long
x = ReleaseCapture()
ReturnVal = SendMessage(hwnd, WM_NCLBUTTONDOWN, HTCAPTION, 0)
End If
End Sub
