modal dialog - Jquery Traversing -

-

I am using JQuery to show a modal dialog box. In the dialog box there is File Upload Control and Upload Button. In addition there are two buttons to save and cancel in.

I need to control file uploads essentially. I have to cross the file control and get the path by using $ (this) I'm able. Parent (). siblings (). Children () Get (1) .value; And display an error message on the click of the upload button. But I want to display the same error to save the button.

Need help in saving the button as I have created a button with the dialog box 

  $ ("#dialog"). Dialog ({bgiframe: true, autoOpen: false, height: 500, width: 600, modal: true, button: {Cancel: jobs} {$ (this) .dialog ('close');} 'Save' : Function () {}}});    
 
 
 From your code example it looks like  inside this  Cancel and Save Handlers is the  #dialog  element, so you can go for all children there. Instead it would be more robust to use a selector instead of a traversal.  $ (this) .find (': file'). Val ()  should work. 
 
 Using selectors will make your code even more strong because it will continue to work even if you add additional elements in your dialog as some commentators have pointed out, giving file upload control a unique ID It will be easy to choose it with the selector. If you need the code to work for multiple dialog boxes with different IDs for the upload field, then you can use a class or other specific selectors in a specific context, such as the selector mentioned above. Find Combined with the method. 
 
 We may need a bit more context to help you, like what the content of the # dialog element is, perhaps to mention the jQuery plugin that defines the .dialog method, it will be useful.

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);

What is expire header and how to achive them in ASP.NET and PHP? -

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
