SilkTest中用parent语句来声明某个window的父窗口，这会帮助silktest在识别该对象时检查其是否是由该父窗口打开，如果parent语句申明的父窗口并不存在，那么该对象无法被正确识别。

有的时候，某些新打开的窗口可能由多个父窗口打开，那么固定的parent语句显然无法完成任务，这个时候有两种方法解决。一是使用动态的tag语句来代替parent的功能，另外就是编写tag函数来动态返回动态的tag。

例如我们想要测试一个silktest onlinehelp的BookmarkDefine窗口(打开silktest onlinehelp->菜单bookmark->define)，正常情况下我们抓取的inc文件如下：

[-] window MainWin SilkTestHelp
[+] multitag "SilkTest Help"
[ ] "$C:/WINDOWS/winhlp32.exe"

[ ] tag "File"
[+] MenuItem Open

[+] TreeView TreeView1
[ ] tag "$14005"
[+] PushButton Display
[+] multitag "Display"
[ ] "$14004"
[ ]
[-] window DialogBox BookmarkDefine
[ ] tag "Bookmark Define"
[ ] parent SilkTestHelp
[+] StaticText BookmarkNameText
[+] multitag "Bookmark name:"
[ ] "$65535"
[+] TextField BookmarkName1
[+] multitag "Bookmark name:"
[ ] "$102"
[+] ListBox BookmarkName2
[+] multitag "Bookmark name:"

[+] PushButton OK
[+] multitag "OK"
[ ] "$1"
[+] PushButton Cancel
[+] multitag "Cancel"
[ ] "$2"
[+] PushButton Delete
[+] multitag "Delete"
[ ] "$104"

注意是
tag "Bookmark Define"
parent SilkTestHelp

使用动态tag的方法如下：
将上面的内容改成
tag "../Bookmark Define"

使用tag函数的方法如下：
[ ] tag GetTag()
[-] string GetTag()
[-] if SilkTestHelp.Exists()
[ ] return "../Bookmark Define"

下面这段代码可以用来测试：

[-] testcase DynamicParent()
[ ] SilkTestHelp.SetActive()
[ ] SilkTestHelp.Bookmark.Define.Check()
[ ] sleep(1)
[ ] BookmarkDefine.Close()
[ ] sleep(1)
