Question

VB控件窗口自适应

用VB写了一个户籍管理系统，里边用到了Datagrid控件，但窗体最大化后，控件大小不随之改变，这代码应该怎么写，写在哪里，请详细一点，我是新手，谢谢

Answer 1

Private FormOldWidth As Long
'原始宽度
Private FormOldHeight As Long
'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, " ", 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

Private Sub Form_Load()
Call ResizeInit(Me) '在装入时必须加入
End Sub

Private Sub Form_Resize()
Call ResizeForm(Me) '控件随之改变
End Sub

Answer 2

Private Sub Form_Resize()
DBGrid1.Width = (Me.Width - DBGrid1.Left * 2) / 2
DBGrid1.Height = (Me.Height - DBGrid1.Top * 2) / 2
End Sub
