摘　要:'这个函数可以使你开发的程序适应各种分辨率，这是我见过的最完美的解决方案！强列推荐

正　文:

一、将以下代码放在模块中：

'API宣言
Declare Function GetDesktopWindow Lib "User32" () As Long
Declare Function GetWindowRect Lib "User32" (ByVal hWnd As Long, rectangle As RECT) As Long

'Type宣言
Type RECT



x1 As Long
y1 As Long
x2 As Long
y2 As Long
End Type

''如果你是在1024*768的分辨率下写的程序，就把下面那句改为
Const DesignSize = 1024，如果是800*600分
'辨率下写的，就改为Const DesignSize = 800
'
'Const DesignSize = 1024
Const DesignSize = 800

'国标码宣言
Dim frm As Form
Dim ctrl As Control
Dim prp As Property
Dim rat As Double
Dim flgSec
Dim X As Long
Dim WinHeight As Long
Dim hWnd As Long
Dim ret As Long
Dim I As Integer
Dim R As RECT
Dim SizeL As Long
Dim SizeT As Long
Dim SizeW As Long
Dim SizeH As Long



'--------------------------------------------------------------------------------



Public Function FormResiz_OnOpen(parFrm As Form, Optional perSizeL As Long, Optional perSizeT As Long, Optional perSizeW As Long, Optional perSizeH As Long)
On Error Resume Next
Set frm = parFrm
'窗口驾驶盘的取得
hWnd = GetDesktopWindow()
'现在分辨率取得
ret = GetWindowRect(hWnd, R)
'比例计算 常例：现在800 开发1024 800/1024 = 0.78加倍
X = (R.x2 - R.x1)
rat = X / DesignSize
SizeL = 0: SizeT = 0: SizeW = 0: SizeH = 0
If Not IsEmpty(perSizeL) = True Then
SizeL = perSizeL * rat
SizeT = perSizeT * rat
SizeW = perSizeW * rat
SizeH = perSizeH * rat
End If



'现在分辨率＝开发分辨率如果终了
If X = DesignSize Then Exit Function
If X < DesignSize Then
'细小策划时、控制＞部分＞表单的次序
Call ChangeCtrl
Call ChengeSec
Call ChangeFrm

'大掬取时、表单＞部分＞控制的次序

Call ChengeSec
Call ChangeCtrl
End If
'最后、表单的使清新
frm.Refresh
Exit Function
End Function
'--------------------------------------------------------------------------------
Private Sub ChangeCtrl()
On Error Resume Next
'控制转

If ctrl.ControlType = 123 or ctrl.ControlType = 124 Then
For Each prp In ctrl.Properties
Select Case prp.Name
Case "FontSize", "DatasheetFontHeight"
prp.value = Fix(prp.value * rat + 0.5)
Case "FontWeight"
prp.value = Fix((prp.value * rat) / 100) * 100
Case "Top", "Height"
prp.value = Fix(prp.value * rat * 0.85)
'prp.value = Fix(prp.value * rat)
Case "Left"
prp.value = Fix(prp.value * rat * 0.9)
Case "Width"
prp.value = Fix(prp.value * rat * 0.7)
End Select
Next prp
'********************************************************************************************
Else
'属性转
For Each prp In ctrl.Properties
'大小·配置关于属性被发现们压缩
Select Case prp.Name

'通常计算假如行…情况之下的 +0.5 之类的话不需要是…但…、

End Select
Next prp
End If
Next ctrl
End Sub
'--------------------------------------------------------------------------------
Private Sub ChengeSec()
On Error GoTo Err_Disp
'部分转
flgSec = True
I = 0
'不存在部分的参照错误化验出终了
Do Until flgSec = False
'部分被发现们高度变更
frm.Section(I).Height = Fix(frm.Section(I).Height * rat)
I = I + 1
Loop
Exit Sub

If Err = 2462 Then
flgSec = False
Resume Next
Else
MsgBox Err.Description
End If
Resume Next
End Sub
'--------------------------------------------------------------------------------
Private Sub ChangeFrm()
On Error Resume Next
'表单的大小变更
'Optional参数数值渡下次收拾ば、而且使合（计算正在完毕）
If SizeL > 0 Then
DoCmd.MoveSize SizeL, SizeT, SizeW, SizeH
Else
'特别是指定啊假如踢、变更了表单的大小表示
'表单的属性（宽与高度）
frm.Width = Fix(frm.Width * rat)
WinHeight = Fix(frm.WindowHeight * rat)
DoCmd.MoveSize , , frm.Width, WinHeight
End If
End Sub

二、用法：

在需要适应分辨率的窗体的Load事'件里加入：

Call FormResiz_OnOpen(Me)
