亲爱的拉吉夫,
根据我的理解,这就是你想要的:
你有一个注册表文件,其数据是根据用户名和访问日期存储的。您希望从文件中获取与您给出的reg-ex匹配的数据。
您是否想要获取数据以及日期,或者您是否使用用户名本身搜索数据?
请更正我我错了。
Dear Rajiv,
As per my understanding, here is what you want:
You have a registry file whose data was stored based on the username and the acess dates. You want to get the data from the file which matches with the reg-ex given by you.
Did you want to get the data along with the date or were you searching the data with the username itself?
Please correct me if I am wrong.
谢谢rellaboyina
让我解释清楚,实际上我使用用户名和日期范围进行搜索。假设用户名''rajiv101''和日期范围''2008-12-01''到''2008-12-05''那么它应该列出所有具有这种条件的记录。
但是我的正则表达式是完全错误的。现在我正在研究那部分,但是如果你有任何想法请告诉我。
谢谢
Rajiv
Thanks rellaboyina
Let me Explain clearly , Actually i am search using both username and date range.Suppose the user name ''rajiv101'' and the date range ''2008-12-01'' to ''2008-12-05'' then it should list all records with this condition.
But my Regex is totally wrong.Now i am working on that part but if u have any idea please let me know.
Thank You
Rajiv
我发现很难解决这个问题。如果有人有任何其他解决方案请告诉我。
