c# - Which .Net 2.0 Exception should I throw in this circumstance? -

-

I am writing another ActiveRecord implementation for a company that is less scared than my code because those designations "Release candidates are there" on the implementation of the Castle Project anyway, I am using attributes on each property in the base class so that they can map to the returned dataset column: 

  [ResultColumnAttribute ("CUST_FIRST_NAME")] Public String First Name {get {r} Eturn _columnName; } Set {_columnName = value; }}

So that when I instantiate the class with a dataset, I specify the value of the column in that property value. When a column is mapped to an attribute, do I want an exception, but I do not see it in the dataset? I do not want to go a custom (lazy) and write, and I think that the app The exception is a little bit mandatory.

This exception is localized in your domain and as if I think you have your own invalid It would be better to type mapping exceptions .

How do I write here: Public invalid mapping exception: exception {public invalid mapping exception () {} public invalid mapping exception (string message): base (message) {} public invalid mapping exception (string message, Exception (innerException): Base (Message, Internal Exception) {} Safe Invalid Mapping Exception (Serialization Information, Streaming Contact Reference): Base (Information, Reference) {}}

There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

sql server - How can I determine which of my SQL 2005 statistics are unused? -

-
After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
