c# - Should I always call Page.IsValid? -

-

I know that never user input is trusted, because undesirable input can compromise the integrity of the application in some way It may be accidental or deliberate; However, there is also a case for calling on the page. IISValid Whenever there are no verification controls on the page (again, I know its wrong procedure to trust user input except for verification)? Does Page.Ivalid display any other type of validity? I looked at MSDN, and the docs indicate that the page ISIILID is only effective if the page has validation controls, or pages. Validity method has been called. A friend of mine suggested that I check the page every time I click the button handlers. Even if there is no validity control or a clear page. Validity call.

I would be the first to tell you that" All input is bad until other input is proved. "However, in this case, I think your friend is wrong because in his argument we can possibly come up with one hundred other qualities which should be checked or set, although the mistake is OK.

Checking If you have a "due validity" scenario - only one is understood - a button that submits the form, its due validity property is set to true. Automatically call page validity and same MA All assumptions regarding the validation group will be checked for validity.

Edit:

Use only the reflector to check it Done and the function is always right if the page does not have a valuer (validation is zero selection).

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. 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
