就是不会出现“控件不动,旁边多出来许多空白的”。
Form改变大小时同时改变其内Control之大小
这个程式只是个范例,但在某些物件上不能使用,例如:Line,因为它没有Top, Left Width, Height所以在本程式中没有作用,不过呢,像这一类的东西可自己用另外程式 去控制。
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 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 End If Next I Ctl.Visible = TempVisible Next Ctl On Error GoTo 0 End Sub
