自动改变窗体大小

收藏

使用如下代码实现改变窗体大小功能，调试运行后，改变vb窗体大小，只是spread窗口大小和字体大小改变
，行宽、列宽没有改变。
问：自动改变窗体大小spread5如何设置？

=============================
Public Class Form1

Dim x As Single = 0
Dim y As Single = 0
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
      '得到原始窗体大小
      x = Me.Width
      y = Me.Height
      setTag(Me)
End Sub

Private Sub Form1_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
'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 = newy * mytag(4)
         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
End Class

你的需求不是要调整窗口大小，是要缩放Spread。

你可以调整ZoomFactor属性，例如：

this.fpSpread1.ActiveSheet.ZoomFactor = 3;
