VB如何实现无标题栏窗体移动

[fytechbbs]

即通过鼠标拖动控件来实现整个窗体的移动？以前看到过相关代码，现在找不到了，各位帮帮我吧！

代码（点击image4时移动窗体，你可以换成别的控件）：

Private Declare Function GetCursorPos Lib "user32" (lpPoint As PointApi) As Long
Dim pos As PointApi
Dim mouselsdown As Boolean
Dim dx, dy As Long
Private Type PointApi
X As Long
Y As Long
End Type

Private Sub Image4_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
' If Y > 240 Then Exit Sub: '当鼠标的位置在此范围时移动有效，你可以改变这一数值
mouselsdown = True
dx = X / 15: dy = Y / 15
End Sub

Private Sub Image4_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
If mouselsdown Then
GetCursorPos pos
Move (pos.X - dx) * Screen.TwipsPerPixelX, (pos.Y - dy) * Screen.TwipsPerPixelX
End If
End Sub

Private Sub Image4_MouseUp(Button As Integer, Shift As Integer, X As Single, Y As Single)
mouselsdown = False
End Sub

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 Any) As Long
Const HTCAPTION = 2
Const WM_NCLBUTTONDOWN = &HA1
Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
ReleaseCapture
SendMessage Me.hwnd, WM_NCLBUTTONDOWN, HTCAPTION, 0&
End Sub
Form可改为其它的控件
