vb 点击控件移动窗体

添加模块  代码如下：
Public 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 Declare Function ReleaseCapture Lib "user32" () As Long

Public Sub DoDrag(TheForm As Form)
    If TheForm.WindowState <> vbMaximized Then
        ReleaseCapture
        SendMessage TheForm.hwnd,&HA1,2,0&
        
    End If
End Sub

在该控件的方法调用：

Private Sub Label1_MouseDown(Button As Integer,Shift As Integer,X As Single,Y As Single)
DoDrag Me
End Sub
