全局代码

Public Sub TextBox_DragDrop(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs)

        Dim path As String = CType(e.Data.GetData(Windows.Forms.DataFormats.FileDrop), System.Array).GetValue(0).ToString()
        sender.Text = path
        sender.Cursor = System.Windows.Forms.Cursors.IBeam
    End Sub

    Public Sub TextBox_DragEnter(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs)
        If (e.Data.GetDataPresent(Windows.Forms.DataFormats.FileDrop)) Then
            e.Effect = Windows.Forms.DragDropEffects.Link
            sender.Cursor = System.Windows.Forms.Cursors.Arrow 
        Else
            e.Effect = Windows.Forms.DragDropEffects.None
        End If
    End Sub

 

 

窗口AfterLoad代码

 

Dim t As WinForm.TextBox = e.Form.Controls("TextBox1")
t.BaseControl.AllowDrop = True

AddHandler t.BaseControl.DragDrop, AddressOf TextBox_DragDrop
AddHandler t.BaseControl.DragEnter, AddressOf TextBox_DragEnter
