窗体的控件随窗体变化自动调整大小

在程序的使用中，如果用户点击最大化或调整窗体的时候，窗体的控件依然不变化，非常不好看，所以我将这段源码贴上，供参考！

非常方便！



Option Explicit
Private ObjOldWidth As Long  '保存窗体的原始宽度
Private ObjOldHeight As Long '保存窗体的原始高度
Private ObjOldFont As Single '保存窗体的原始字体比

'在调用ResizeForm前先调用本函数
Public Sub ResizeInit(FormName As Form)
  Dim Obj As Control
  
  ObjOldWidth = FormName.ScaleWidth
  ObjOldHeight = FormName.ScaleHeight
  ObjOldFont = FormName.Font.Size / ObjOldHeight
  On Error Resume Next
  For Each Obj In FormName
    Obj.Tag = Obj.Left & " " & Obj.Top & " " & Obj.Width & " " & Obj.Height & " "
  Next Obj
  
  On Error GoTo 0
End Sub

'按比例改变表单内各元件的大小，
'在调用ReSizeForm前先调用ReSizeInit函数
Public Sub ResizeForm(FormName As Form)

  Dim Pos(4) As Double
  Dim i As Long, TempPos As Long, StartPos As Long
  Dim Obj As Control
  Dim ScaleX As Double, ScaleY As Double
  
  ScaleX = FormName.ScaleWidth / ObjOldWidth
  '保存窗体宽度缩放比例
  ScaleY = FormName.ScaleHeight / ObjOldHeight
  '保存窗体高度缩放比例
  On Error Resume Next
  
  For Each Obj In FormName
    StartPos = 1
    For i = 0 To 4
      '读取控件的原始位置与大小
      TempPos = InStr(StartPos, Obj.Tag, " ", vbTextCompare)
      If TempPos > 0 Then
        Pos(i) = Mid(Obj.Tag, StartPos, TempPos - StartPos)
        StartPos = TempPos + 1
      Else
        Pos(i) = 0
      End If
      
      '根据控件的原始位置及窗体改变大
      '小的比例对控件重新定位与改变大小
      Obj.Move Pos(0) * ScaleX, Pos(1) * ScaleY, Pos(2) * ScaleX, Pos(3) * ScaleY
      Obj.Font.Size = ObjOldFont * FormName.ScaleHeight
    Next i
  
  Next Obj
  
  On Error GoTo 0
End Sub

Private Sub Form_Resize()
  '确保窗体改变时控件随之改变
  Call ResizeForm(Me)
End Sub

Private Sub Form_Load()
  '在程序装入时必须加入
  Call ResizeInit(Me)
End Sub
