跪求一款能让VB控件随着窗口放大缩小自动适应的第三方控件
跪求一款能让VB控件随着窗口放大缩小自动适应的第三方控件，或者具体点的方法，代码，说清楚点，小弟是小白。。。
[解决办法]
没有，要自己写，其实也不难，在Form_Resize()事件里加代码，那么当窗体的大小改变时就会引发这个事件，你就能改变控件的大小适应窗体。
例如：
Private Sub Form_Resize()'先放一个按钮在窗体上Command1.Left=120'设置按钮的左距离是120Command1.Width=Me.Width-480'设置按钮一的宽度，Me代表窗体Command1.Top=120'设置按钮的顶距离是120Command1.Height=Me.Height-800'设置按钮一的宽度，Me代表窗体End Sub
[解决办法]
不知道哪抓到的?写成模块再去调用就好了?
Option ExplicitPrivate 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Private 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 0End 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Private Sub ResizeForm(FormName As Form)Dim Pos(4) As DoubleDim i As Long, TempPos As Long, StartPos As LongDim Obj As ControlDim 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 0End SubPrivate Sub Form_Load() Call ResizeInit(Me) '在程序装入时必须加入End SubPrivate Sub Form_Resize() Call ResizeForm(Me) '确保窗体改变时控件随之改变End Sub
