regex - How to replace forward slashes with backslashes in a string in Emacs Lisp? -

-

I would like to change the forward slash for backslashes in emacs lisp. If I use it: 

  (replace-regexp-in-string "\ /" \\ "path))

I get an error 

  (Invalid use of `\\ 'in the replacement text)"

How to represent backslash in another regexp?

What are you looking for in "C: \\ foo \\ bar" / P>

For example, if you string the length 1 with the backslash character, the textual presentation of the string "C: \ foo \ bar" Do you: 

  (make-string 1? \\)

You get the following response (such as in the winbuffer, when you pick up CX CE Another way to get what you want is to switch the "literal" flag to: 

  (replace-regexp-in-string "/" "\\" path tt)

By the way, you do not have to avoid slash.

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 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.

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
