vb怎么才能使窗口最大化时候其他控件怎么一起变大

For Each Ctl In Me
改成For Each Ctl In Me.Controls 试试

有两句错误，第一个的确缺for，第二句then后面不能接语句，这样才能加else和endif，修改后代码如下：
Option Explicit
Private InitWidth As Long ' Form 的原始大小
Private InitHeight As Long
Private Sub Form_Load()
InitWidth = ScaleWidth
InitHeight = ScaleHeight
Dim Ctl As Control ' 记录每个 Control 的原始位置、大小、字型大小, 放在 Tag 属性中
On Error Resume Next '确保left, top, width, height, Tag属性没有全有的Control For Each Ctl In Me '也能正常执行
For Each Ctl In Me.Controls
  Ctl.Tag = Ctl.Left & " " & Ctl.Top & " " & Ctl.Width & " " & Ctl.Height & " "
  Ctl.Tag = Ctl.Tag & Ctl.FontSize & " "
Next Ctl
On Error GoTo 0
End Sub

Private Sub Form_Resize()
Dim D(4) As Double
Dim I As Long
Dim TempPos As Long
Dim StartPos As Long
Dim Ctl As Control
Dim TempVisible As Boolean
Dim ScaleX As Double
Dim ScaleY As Double

ScaleX = ScaleWidth / InitWidth
ScaleY = ScaleHeight / InitHeight
On Error Resume Next
For Each Ctl In Me
  TempVisible = Ctl.Visible
  Ctl.Visible = False
  StartPos = 1 ' 读取 Control 的原始位置、大小、字型大小
  For I = 0 To 4
    TempPos = InStr(StartPos, Ctl.Tag, " ", vbTextCompare)
    If TempPos > 0 Then
      D(I) = Mid(Ctl.Tag, StartPos, TempPos - StartPos)
      StartPos = TempPos + 1
    Else
      D(I) = 0
    End If ' 根据比例设定 Control 的位置、大小、字型大小
    Ctl.Move D(0) * ScaleX, D(1) * ScaleY, D(2) * ScaleX, D(3) * ScaleY '
    Ctl.Width = D(2) * ScaleX '
    Ctl.Height = D(3) * ScaleY
    If ScaleX < ScaleY Then Ctl.FontSize = D(4) * ScaleX Else Ctl.FontSize = D(4) * ScaleY
  Next I
  Ctl.Visible = TempVisible
Next Ctl
End Sub

版主，可否将它改为函数方便调用，另外这个代码似乎对Label无效。
