QTP的3类顺序标识（Ordinal Identifiers） 收藏
对于顺序标识（Ordinal Identifiers），QTP的帮助文档是这样说的：
An ordinal identifier assigns a numerical value to a test object that indicates its order or location relative to other objects with an otherwise identical description (objects that have the same values for all properties). This ordered value provides a backup mechanism that enables QuickTest to create a unique description to recognize an object when the defined properties are not sufficient to do so.
总共有3类这样的顺序标识（Ordinal Identifiers）：Location, Index 和 CreationTime
其中CreationTime仅适用于Browser对象。
顺序标识（Ordinal Identifiers）通常在描述性编程时使用。
例1：location（location顺序标识是用上到下进行的）
'Text Box 1
Browser("title:=.*Descriptive.*").Page("micclass:=Page").WebEdit("name:=dpTest","location:=0").Set "1"
'Text Box 3
Browser("title:=.*Descriptive.*").Page("micclass:=Page").WebEdit("name:=dpTest","location:=1").Set "2"
'Text Box 2
Browser("title:=.*Descriptive.*").Page("micclass:=Page").WebEdit("name:=dpTest","location:=2").Set "3"
'Text Box 4
Browser("title:=.*Descriptive.*").Page("micclass:=Page").WebEdit("name:=dpTest","location:=3").Set "4"
例2：index（index顺序标识是从左到右进行的）
'Text Box 1
Browser("title:=.*Descriptive.*").Page("micclass:=Page").WebEdit("name:=dpTest", "index:=0").Set "1"
'Text Box 2
Browser("title:=.*Descriptive.*").Page("micclass:=Page").WebEdit("name:=dpTest", "index:=1").Set "2"
'Text Box 3
Browser("title:=.*Descriptive.*").Page("micclass:=Page").WebEdit("name:=dpTest", "index:=2").Set "3"
'Text Box 4
Browser("title:=.*Descriptive.*").Page("micclass:=Page").WebEdit("name:=dpTest", "index:=3").Set "4"
例3：CreationTime（仅对浏览器对象生效，按对象产生时间先后顺序排列）
SystemUtil.Run "iexplore.exe", "http://www.HP.com" 'CreationTime 0
SystemUtil.Run "iexplore.exe", "http://www.AdvancedQTP.com" 'CreationTime 1
SystemUtil.Run "iexplore.exe", "http://www.LinkedIn.com" 'CreationTime 2
Browser( "creationtime:=" ).Highlight 'Highlight HP.com
Browser( "creationtime:=1" ).Highlight 'Highlight AdvancedQTP.com
Browser( "creationtime:=2" ).Highlight 'Highlight LinkedIn.com
