Action 属性 (ActiveX)
指定要对图形执行的与安全相关的操作。 支持的平台:仅限 AutoCAD for Windows;AutoCAD LT for Windows 不支持 属性值只读:不 类型:长; 枚举AcadSecurityParamsType 为图形加密、图形特性加密、数字签名或时间戳指定以下一个或多个常量。
注意:从基于 AutoCAD-2016 的产品开始,已停止使用密码保护图形文件的功能。常量值 和 已过时。如果使用这两个常量中的任何一个,则该方法将产生错误。ACADSECURITYPARAMS_ENCRYPT_DATAACADSECURITYPARAMS_ENCRYPT_DATASaveAs
言论每个常量表示一个与安全相关的操作。使用该属性时,在操作集中的某个时间点,必须将该属性设置为常量。ActionActionACADSECURITYPARAMS_SIGN_DATA 若要指定多个与安全相关的操作,请添加表示这些操作的常量。例如,若要对图形进行签名并使用时间戳,请指定以下内容: ACADSECURITYPARAMS_SIGN_DATA + ACADSECURITYPARAMS_ADD_TIMESTAMP 例子VBA: Sub Example_Action()
' This example attaches a digital signature and accompanying data to a file,
' and saves the file.
Dim sp As AcadSecurityParams
Set sp = GetInterfaceObject("AutoCAD.SecurityParams." & Left(AcadApplication.Version, 2))
' Attach a digital signature and timestamp it
sp.Action = AcadSecurityParamsType.ACADSECURITYPARAMS_SIGN_DATA _
+ AcadSecurityParamsType.ACADSECURITYPARAMS_ADD_TIMESTAMP
' Certificate details follow
sp.Subject = "Thawte Freemail Member"
sp.Issuer = "Personal Freemail RSA 2000.8.30"
sp.SerialNumber = "073848"
sp.Comment = "This is now signed"
sp.TimeServer = "NIST(time.nist.gov)"
