移动没有标题栏的窗口   
 
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
