VB 控件大小随窗体改变而改变

我在做了控件大小随窗体改变而改变的操作以后，运行时窗体最大化以后，部分控件却总是不能在指定位置上显示，比如最大化后几乎所有的ComboBox都是跑到了其他位置上，而其他控件都在原位．请问如何调整？

代码如下：
Option Explicit
Private FormOldWidth As Long
'保存窗体的原始宽度
Private FormOldHeight As Long
'保存窗体的原始高度

'在调用ResizeForm前先调用本函数
Public Sub ResizeInit(FormName As Form)
Dim Obj As Control
FormOldWidth = FormName.ScaleWidth
FormOldHeight = FormName.ScaleHeight
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 / FormOldWidth
'保存窗体宽度缩放比例
ScaleY = FormName.ScaleHeight / FormOldHeight
'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
Next I
Next Obj
On Error GoTo 0
End Sub

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

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

'功能:：窗体大小改变时窗体内的控件大小也随之动态改变
'使用方法：
'在相应的窗体程序中加入如下语句：
'---------------------------------------------------
'Private Sub Form_Load()
' Call ResizeInit(Me) '在程序装入时必须加入
'End Sub

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