一劳永逸让VB自动改变控件大小

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, \" \

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

----本例中给出了二个函数:ResizeInit和ResizeForm,在调用ResizeForm之前必须先调用ResizeInit。你可以将本程序拷到窗体代码段里，然后在窗体里加入任意控件即可进行测试
