VB控件随窗体大小改变而改变

VB控件随窗体大小改变而改变 本人发现VB2008前版本使控件位置和大小自动适应窗体变化的提问很多。但回答的正确的不多。本人用vb6.0也遇到此问题。认真研究的一下。给出最正确的三种模式给大家借鉴。有更好方法可以在交流。代码是无需更改的。 第一种。就是最实用的，就是所有控件的width和height按比例随窗体变化，位置也是当然是按比例哦。控件的字体不变。如下复制到代码: '改比例，字体不该。最实用 Option Explicit 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 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 '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, " ", 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 0 End Sub 第二种，只位置就是控件的left和top随着变。其他都不变。如果变化大了不好看。如下复制: 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 Private Sub Form_Resize() '确保窗体改变时控件随之改变 Call ResizeForm(Me) End Sub Private '在程序装入时必须加入 Call ResizeInit(Me) End Sub ' '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 Next i Next Obj End Sub 第三种，就是所有的都按比例。包括大小。字体，位置，就像放大镜的感觉。复制如下: 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 '窗体部分 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 ' '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 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 End Sub
