IncrementalSavePercent Property （ActiveX）

工 务 局：

object.IncrementalSavePercent

对象

类型：首选项打开保存

此属性适用的对象。

属性值

只读：不

类型：整数

有效范围为 0 到 100。

言论

此属性的初始值为 50。

达到指定的百分比时，AutoCAD 将执行完全保存，而不是增量保存。完全节省，消除空间浪费。如果将此属性设置为 0，则每次保存都是完全保存。

尽管增量保存会增加绘图的大小，但不要设置非常低的值。为获得最佳性能，请将值设置为 50。如果内存成为问题，请将值设置为 25。如果将该值设置为 20 或更小，则性能会显著降低。值越低会降低程序的性能，因为 AutoCAD 执行耗时的完整保存的频率更高。

例子

工 务 局：

Sub Example_IncrementalSavePercent()
    ' This example returns the current setting of
    ' IncrementalSavePercent. It then changes the value, and finally
    ' it resets the value back to the original setting.
    
    Dim preferences As AcadPreferences
    Dim currIncrementalSavePercent As Integer
    Dim newIncrementalSavePercent As Integer
    
    Set preferences = ThisDrawing.Application.preferences
    
    ' Retrieve the current IncrementalSavePercent value
    currIncrementalSavePercent = preferences.OpenSave.IncrementalSavePercent
    MsgBox "The current value for IncrementalSavePercent is " & currIncrementalSavePercent, vbInformation, "IncrementalSavePercent Example"
    
    ' Change the value for IncrementalSavePercent
    newIncrementalSavePercent = 20
    preferences.OpenSave.IncrementalSavePercent = newIncrementalSavePercent
    MsgBox "The new value for IncrementalSavePercent is " & newIncrementalSavePercent, vbInformation, "IncrementalSavePercent Example"
    
    ' Reset IncrementalSavePercent to its original value
    preferences.OpenSave.IncrementalSavePercent = currIncrementalSavePercent
    MsgBox "The IncrementalSavePercent value is reset to " & currIncrementalSavePercent, vbInformation, "IncrementalSavePercent Example"
End Sub
