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！

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
