Answer 1

Option Explicit
Private FormOldWidth As Long
Private FormOldHeight As Long
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

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
ScaleY = FormName.ScaleHeight / FormOldHeight
On Error Resume Next
For Each Obj In FormName
StartPos = 1
For i = 0 To 4
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
Obj.Move Pos(0) * ScaleX, Pos(1) * ScaleY, Pos(2) * ScaleX, Pos(3) * ScaleY
Next i
Next Obj
On Error GoTo 0
End Sub

改变Form1上控件大小，宽放大m倍，高放大n倍
Private Sub fangda()
Dim myControl As Control
Dim m As Single, n As Single
m = 1.5
n = 1.2
For Each myControl In Form1.Controls
myControl.Move myControl.Left, myControl.Top, myControl.Width * m, myControl.Height * n
Next
End Sub
