控件随窗体大小变化？

kyzh 2003-12-26 05:44:28
sstab控件里有两行选择，里面都有很多控件，我在Form_Load的时候改变控件的大小时，只能改变sstab控件第一个选择里的控件大小，当我选择第行时,里面的控件都不见了，页面都是空白,为什么？

在Private Sub Form_Resize()事件里做吧

楼上的对，用个RESIZE32.OCX控件就搞掂了，我有要吗？

我是用以下这种方法改变的：
Option Explicit
Public Xtwips As Integer, Ytwips As Integer
Public Xpixels As Integer, Ypixels As Integer
Type FRMSIZE
Height As Long
Width As Long
End Type
Public RePosForm As Boolean
Public DoResize As Boolean
Dim MyForm As FRMSIZE
Dim DesignX As Integer
Dim DesignY As Integer
Dim ScaleFactorX As Single, ScaleFactorY As Single
Sub Resize_For_Resolution(ByVal SFX As Single, ByVal SFY As Single, MyForm As Form)
Dim i As Integer
Dim SFFont As Single
SFFont = (SFX + SFY) / 2
On Error Resume Next
With MyForm
For i = 0 To .Count - 1
If TypeOf .Controls(i) Is ComboBox Then
.Controls(i).Left = .Controls(i).Left * SFX
.Controls(i).Top = .Controls(i).Top * SFY
.Controls(i).Width = .Controls(i).Width * SFX
Else
.Controls(i).Move .Controls(i).Left * SFX, _
.Controls(i).Top * SFY, _
.Controls(i).Width * SFX, _
.Controls(i).Height * SFY
End If
.Controls(i).FontSize = .Controls(i).FontSize * SFFont
Next i
If RePosForm Then
.Move .Left * SFX, .Top * SFY, .Width * SFX, .Height * SFY
End If
End With
End Sub

Public Sub FormResize(TheForm As Form)
Dim ScaleFactorX As Single, ScaleFactorY As Single
If Not DoResize Then
DoResize = True
Exit Sub
End If
RePosForm = False
ScaleFactorX = TheForm.Width / MyForm.Width
ScaleFactorY = TheForm.Height / MyForm.Height
Resize_For_Resolution ScaleFactorX, ScaleFactorY, TheForm
MyForm.Height = TheForm.Height
MyForm.Width = TheForm.Width
End Sub

Public Sub AdjustForm(TheForm As Form)
Dim Res As String ' Returns resolution of system
' Put the design time resolution in here
DesignX = 640
DesignY = 480
RePosForm = True
DoResize = False
Xtwips = Screen.TwipsPerPixelX
Ytwips = Screen.TwipsPerPixelY
Ypixels = Screen.Height / Ytwips
Xpixels = Screen.Width / Xtwips
ScaleFactorX = (Xpixels / DesignX)
ScaleFactorY = (Ypixels / DesignY)
TheForm.ScaleMode = 1
Resize_For_Resolution ScaleFactorX, ScaleFactorY, TheForm
Res = Str$(Xpixels) + " by " + Str$(Ypixels)
Debug.Print Res
MyForm.Height = TheForm.Height
MyForm.Width = TheForm.Width
End Sub

Private Sub Form_Load()
Call AdjustForm(Me)
End Sub

Private Sub Form_Resize()
Call FormResize(Me)
End Sub
其他控件都可以，就是sstab控件第二个选行里的控件不行

你可以試下這個﹐但是我沒有在sstab.中測試

有没有简单的方法：实现控件随Form的大小变化而变化啊（位置也相对变化）？

原因是你改变大小之前没有设置Tab值。你必须这样：
sstab.tab=0
'处理第一页的控件大小
sstab.tab=1
'处理第二页的控件大小
窗体控件大小随窗体大小变化而变化
VB窗体控件大小随窗体大小变化而变化的程序
VB窗体控件大小随窗体大小变化而变化
VB窗体控件大小随窗体大小变化自動調整 有时窗体变化后，如改变分辨率后控件大小却不能随之改变。手工代码调整实在麻烦，下面的模块实现自动查找窗体上控件并使其改变大小以适应窗体变化。 在Form的Resize事件中调用函数Resize_All就能实现控件自动调整大小，如： Private Sub Form_Resize() Dim H, i As Integer On Error Resume Next Resize_ALL Me 'Me是窗体名，Form1,Form2等等都可以 End Sub 在模块中添加以下代码： Public Type ctrObj Name As String Index As Long Parrent As String Top As Long Left As Long Height As Long Width As Long ScaleHeight As Long ScaleWidth As Long End Type Private FormRecord() As ctrObj Private ControlRecord() As ctrObj Private bRunning As Boolean Private MaxForm As Long Private MaxControl As Long Private Const WM_NCLBUTTONDOWN = &HA1 Private Declare Function SendMessage Lib "USER32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long Private Declare Function ReleaseCapture Lib "USER32" () As Long Function ActualPos(plLeft As Long) As Long If plLeft < 0 Then ActualPos = plLeft + 75000 Else ActualPos = plLeft End If End Function Function FindForm(pfrmIn As Form) As Long Dim i As Long FindForm = -1 If MaxForm > 0 Then For i = 0 To (MaxForm -

vb控件随窗体大小变化而变化
控件按比例随窗体大小改变而变化.控件大小不会因为窗体最大化而改变布局，不会影响美观
C# 窗体中的控件及菜单随窗体大小而变化
C# 窗体中的控件及菜单随窗体大小而变化 让C#窗体中的控件、按钮以及菜单等随窗体的大小变化而变化，在Word中，大家会见到，当Word的窗体不是最大化的时候，那些操作按钮会自动隐藏起来，用箭头来代替，点击箭头会显示出被隐藏的按钮，那么这个窗体就实现这种功能，当你把本窗口拖大的时候，它就会完全显示出那些菜单按钮，把窗口变小，它们就自动隐藏了。
