vb.net 控件（包括字体）随窗体按比例缩放

		
Public Class frmDl
    Dim x As Single = 0
    Dim y As Single = 0
 
    Private Sub frmDl_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        x = Me.Width
        y = Me.Height
        setTag(Me)
    End Sub
    递归取控件的原始大小和位置，用tag来纪录
    Private Sub setTag(ByVal obj As Object)
        For Each con As Control In obj.Controls
            con.Tag = con.Width & ":" & con.Height & ":" & con.Left & ":" & con.Top & ":" & con.Font.Size
            如果是容器控件，则递归继续纪录
            If con.Controls.Count > 0 Then
                setTag(con)
            End If
        Next
    End Sub
    递归重新设定控件的大小和位置
    Private Sub setControls(ByVal newx As Single, ByVal newy As Single, ByVal obj As Object)
        For Each con As Control In obj.Controls
            con.AutoSize = False
            Dim mytag() As String = con.Tag.ToString.Split(":")
            con.Width = mytag(0) * newx
            con.Height = mytag(1) * newy
            con.Left = mytag(2) * newx
            con.Top = mytag(3) * newy
            计算字体缩放比例，缩放字体
            Dim currentSize As Single = (mytag(1) * newy * mytag(4)) / mytag(1)
            con.Font = New Font(con.Font.Name, currentSize, _
                con.Font.Style, con.Font.Unit)
            如果是容器控件，则递归继续缩放
            If con.Controls.Count > 0 Then
                setControls(newx, newy, con)
            End If
        Next
    End Sub
 
    Private Sub frmDl_Resize(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Resize
        得到现在窗体的大小，然后根据原始大小计算缩放比例
        Dim newx As Single = Me.Width / x
        Dim newy As Single = Me.Height / y
        setControls(newx, newy, Me)
    End Sub
End Class
