移动没有标题的窗体

我们一般是用鼠标按住窗口的标题栏，然后移动窗口，当窗口没有标题栏时，我们可以用下面的方法来移动窗口： 　 在 BAS 文件中声明： Declare Function ReleaseCapture Lib "user32" () As Long Declare Function SendMessage Lib "user32" _ Alias "SendMessageA" ( _ ByVal hwnd As Long, ByVal wMsg As Long, _ ByVal wParam As Long, lParam As Any) As Long Public Const HTCAPTION = 2 Public Const WM_NCLBUTTONDOWN = &HA1 　 然后，在 Form_MouseDown 事件中： Private Sub Form_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single) ReleaseCapture SendMessage hwnd, WM_NCLBUTTONDOWN, HTCAPTION, 0& End Sub
