类别:VB语言 点击:0 评论:0 推荐:


    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
