我用这个代码来移动窗体。by(Handles Me.MouseDown,MyListBox.MouseDown)
Public Enum ResizeDirection
None = 0
Left = 1
TopLeft = 2
Top = 3
TopRight = 4
Right = 5
BottomRight = 6
Bottom = 7
BottomLeft = 8
End Enum
Private _resizeDir As ResizeDirection = ResizeDirection.None
Private Const WM_NCLBUTTONDOWN As Integer = &HA1
Private Const HTBORDER As Integer = 18
Private Const HTBOTTOM As Integer = 15
Private Const HTBOTTOMLEFT As Integer = 16
Private Const HTBOTTOMRIGHT As Integer = 17
Private Const HTCAPTION As Integer = 2
Private Const HTLEFT As Integer = 10
Private Const HTRIGHT As Integer = 11
Private Const HTTOP As Integer = 12
Private Const HTTOPLEFT As Integer = 13
Private Const HTTOPRIGHT As Integer = 14
<System.Runtime.InteropServices.DllImport("user32.dll")>
Public Shared Function ReleaseCapture() As Boolean
End Function
<System.Runtime.InteropServices.DllImport("user32.dll")>
Public Shared Function SendMessage(ByVal hWnd As IntPtr, ByVal Msg As Integer, ByVal wParam As Integer, ByVal lParam As Integer) As Integer
End Function
Private Sub MoveForm()
ReleaseCapture()
SendMessage(Me.Handle, WM_NCLBUTTONDOWN, HTCAPTION, 0)
End Sub
Private Sub FormMoveByListBox(sender As Object, e As MouseEventArgs) Handles Me.MouseDown, MyListBox.MouseDown
If e.Button = MouseButtons.Left And Me.WindowState <> FormWindowState.Maximized Then
MoveForm()
End If
End Sub
Private Sub MyListBox_DoubleClick(sender As Object, e As EventArgs) Handles MyListBox.DoubleClick
'Not Work This Event.
End Sub
我想让事件与(SendMessage)vs2019-vb.net我的列表框没有双击事件。
