exception - wpf DoDragDrop IndexOutOfRangeException -

-

I have found this solution that I am trying to implement drag and drop behavior among a group of ListViews Uses full properties:

But whenever I try to drag and drop, I get the following error message in the debug log:

My 'xx The first chance of type 'System.IndexOutOrRangeException' occurred in '

exception I tracked it down and it You can see that DragDrop.DoDragDrop is running, but since the exception has just been swallowed, I do not know where this code is being thrown away from. How can I find the exception?

The main problem with my problem was that I do not know how to break the Visual Studio when An exception was thrown within the WPF code because I was doing drag and drop operations, this can be done under the debug menu in Visual Studio:

debug -> exception -> exception Locate it that you are interested in and click on the checkbox to make the debugger breakdown exception The expertise.

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.

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
