问题简述如题，还望哪位大虾指点，不胜感激

 

  以 QTP 自带的Windows Application (飞机定票程序）为例，登陆场景的描述性编程脚本如下：

Dialog("text:=Login", "nativeclass:=#32770").WinEdit("attached text:=Agent Name","nativeclass:=Edit").Set "1234"
Dialog("text:=Login", "nativeclass:=#32770").WinButton("text:=Help","nativeclass:=Button").Click
Dialog("text:=Login", "nativeclass:=#32770").Dialog("text:=Flight Reservations","nativeclass:=#32770").WinButton("text:=OK","nativeclass:=Button").Click
Dialog("text:=Login", "nativeclass:=#32770").WinEdit("attached text:=Password","nativeclass:=Edit").SetSecure"4fed77fe165419c198d7beee3c1f1d2fa0424f8e"
Dialog("text:=Login", "nativeclass:=#32770").WinButton("text:=OK","nativeclass:=Button").Click

 

  尝试Run这段脚本的时候，QTP提示错误如下：

 

(为了避免图片无法正常现实，copy error message如下：

Cannot identify the object "[ WinEdit ]" (of class WinEdit). Verify that this object's properties match an object currently displayed in your application.

Line (12): "Dialog("text:=Login", "nativeclass:=#32770").WinEdit("attached text:=Agent Name","nativeclass:=Edit").Set "1234"".

Tip: If the objects in your application have changed, the Maintenance Run Mode can
help you identify and update your steps and/or the objects in your repository.）

 

  奇怪的是如果将用对象库和对象识别的话就能正常运行：

Dialog("Login").WinEdit("Agent Name:").Set "1234"
Dialog("Login").WinButton("Help").Click
Dialog("Login").Dialog("Flight Reservations").WinButton("OK").Click
Dialog("Login").WinEdit("Password:").SetSecure "4fed77fe165419c198d7beee3c1f1d2fa0424f8e"
Dialog("Login").WinButton("OK").Click
Window("Flight Reservation").WinMenu("Menu").Select "File;Exit"

 

  纠结了好几天了，网上也查不出有效的解决方法，哪位大虾知道要怎么处理这种异常吗？
