wpf controls - How to make my WPF UserControl work with CompositeCollection -

-

I have a wpf user control that displays an IEnumerable items Source Dependency Property I bind this property to a ListBox control in my UserControl.

I would like to know how a compositeclass is given, how can I do my user control work? Currently I'm using my control like this: 

  & lt; My: uc & gt; & Lt; Mary: uc.ItemsSource & gt; & Lt; CompositeCollection & gt; & Lt; Collection archive = "{my binding}" & gt; & Lt; / Consolidate & gt; & Lt; Collection archive = "{my binding}" & gt; & Lt; / Compatibility & gt; & Lt; / CompositeCollection & gt; & Lt; / Mary: uc.ItemsSource & gt; & Lt; / Mary: UC & gt;

I have to display the content of these collection contents in this list archive box, but do not count it through the container at this time. My listboxes are only two "System.Data.CollectionContainer" items Are there.

[B] EDIT: [/ B] XAM designer informs me that "property does not support the types of items 'source' type 'compositecollection'." I think this is my problem ..but how do I create this "support"? "What you are getting is the toasting method of your object, which by default gives the name of the type.

Try to override the ToString and return the value that you want to make your list Want to see it in.

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
