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
