AutoSaveInterval 属性（ActiveX）

2024-5-18 17:52| 发布者: admin| 查看: 126| 评论: 0|原作者: admin|来自: AutoCAD

指定自动保存间隔（以分钟为单位）。

支持的平台：仅限 Windows

签名

VBA：

object.AutoSaveInterval

对象

类型：PreferencesOpenSave

此属性应用于的对象。

属性值

只读：不

类型：整数

0 >= 自动保存间隔 <= 600

等于 0 的间隔将禁用自动保存。

大于 0 的间隔会自动以指定的间隔保存图形。

言论

此属性的初始设置为 120。

对图形进行更改后，计时器将立即启动。每当保存图形时，它就会重置并重新启动。除非使用该属性指定了其他名称，否则当前图形将保存为 auto.sv$。AutoSavePath

注意：此属性也由 SAVETIME 系统变量控制。ISAVEBAK 系统变量（使用属性设置）可提高增量保存的速度，尤其是对于较大的图形。ISAVEPERCENT 系统变量（使用该属性设置）确定图形中允许的浪费空间量。CreateBackupIncrementalSavePercent

例子

VBA：

Sub Example_AutoSaveInterval()
    ' This example returns the current setting of
    ' AutoSaveInterval. It then changes the value, and finally
    ' it resets the value back to the original setting.
    
    Dim preferences As AcadPreferences
    Dim currAutoSaveInterval As Integer
    Dim newAutoSaveInterval As Integer
    
    Set preferences = ThisDrawing.Application.preferences
    
    ' Retrieve the current AutoSaveInterval value
    currAutoSaveInterval = preferences.OpenSave.AutoSaveInterval
    MsgBox "The current value for AutoSaveInterval is " & currAutoSaveInterval, vbInformation, "AutoSaveInterval Example"
    
    ' Change the value for AutoSaveInterval
    If currAutoSaveInterval = 0 Then
        newAutoSaveInterval = 10
    Else
        newAutoSaveInterval = 0
    End If
    preferences.OpenSave.AutoSaveInterval = newAutoSaveInterval
    MsgBox "The new value for AutoSaveInterval is " & newAutoSaveInterval, vbInformation, "AutoSaveInterval Example"
    
    ' Reset AutoSaveInterval to its original value
    preferences.OpenSave.AutoSaveInterval = currAutoSaveInterval
    MsgBox "The AutoSaveInterval value is reset to " & currAutoSaveInterval, vbInformation, "AutoSaveInterval Example"
End Sub
