So i bumped in to this:  Public Stam {        public Stam() {Console.WriteLine("Stam");}         ~Stam(){Console.WriteLine("Stam")}        }   What exactly is the ~? and what will happen when i call the Stam class.
I am looking at some code and it has this statement:    ~ConnectionManager() {     Dispose(false); }   The class implements the IDisposable interface, but I do not know if that is part of that the tilde(~) is used for.
Automatic labeling of enumeration items Xml validation using XSD schema The following code helps me validate an XML file with an XSD schema.  XmlReaderSettings settings = new XmlReaderSettings(); settings.Schemas.Add(null, xsdFilePath); settings.ValidationType = ValidationType.Schema; settings.ValidationEventHandler += new System.Xml.Schema.ValidationEventHandler(settings_ValidationEventHandler); XmlDocument document = new XmlDocument(); document.Load(xmlFilePath); XmlReader rdr = XmlReader.Create(new StringReader(document.InnerXml), settings);  while (rdr.Read()) {  } isValid = true;   The ValidationEventHandler also tells me what the errors are, but doesn't tell me on 'where' or 'on which line' they are located. Is there any way to get the line number where the XML fails to be validated? I tend to use the terminal a lot,  So I wondering if there is a way I can make Ctrl+Alt+T focus the existing terminal if there is one, otherwise create a new terminal? This is a question that arose in the comments here:   I normally hide footnotes from the TOC by doing this:  \section[title]{title\footnote{This is a footnote.}}.   This works in a lot of document classes (memoir, article, ...), but not in all of them. amsbook, for example, uses the optional argument only for the running heads so the footnote mark still ends up in the TOC. So what is the 'universal solution'? Uninstall, Activate, Deactivate a plugin: typical features & how-to I'm making a WordPress plugin.

Project point onto line in Latitude/Longitude Given line AB made from two Latitude/Longitude co-ordinates, and point C, how can I calculate the position of D, which is C projected onto D.  Diagram: Should I always use a comma after "e.g." or "i.e."? It seems that "e.g." is always followed by a comma but "i.e." is not. Why is that? How do I install a .tar.gz (or .tar.bz2) file?

My primary server with SQL Server 2005 broke down, so I've started up the log-shipped database on the secondary server. The database is live on the secondary server, and I just need to remove the log shipping settings for it, while the primary server is no longer accessible.  It seems that the sp_delete_log_shipping_secondary_database stored procedure should be executed on the secondary server to do this, which "removes a secondary database and removes the local history and remote history", as it is stated on .  Would this also remove the database itself? Or only the log shipping settings for it? And what will it do when the primary server is not accessible?  I must not loose the database on the secondary server, as it is already in use. Usage of "they" / "them" / "their" when the person's gender is not known Graphical interface for generating presentation slides Is there a good graphical interface, similar to PowerPoint or LibreOffice Impress, for generating presentation slides?  When writing documents I prefer to write my text and LaTeX-markups using a text-editor and not using a graphical tool like LyX. However, in the case of presentation slides I want to see the layout and to have the ability to immediately see what you get e.g. by moving a picture with arrow keys.  ADDITION: The background to my question is as follows. I have used PowerPoint for more than a decade and like to use a WYSIWYG tool when making presentation slides. However, I can not use PowerPoint on my current computer and I think the output from LibreOffice Impress is inferior. As a long-time user of LaTeX, I have considered using SliTeX or Beamer but unfortunately I do not like the way of working. The end result is of course superior, but I found it very time-consuming and tiresome to e.g. adjust the position and size of pictures. How prove this nice limit $\lim\limits_{n\to\infty}\frac{a_{n}}{n}=\frac{12}{\log{432}}$ Nice problem:  Let $a_{0}=1$ and $$a_{n}=a_{\left\lfloor n/2\right\rfloor}+a_{\left\lfloor n/3 \right\rfloor}+a_{\left\lfloor n/6\right\rfloor}.$$  Show that  $$\lim_{n\to\infty}\dfrac{a_{n}}{n}=\dfrac{12}{\log{432}},$$  where $\lfloor x \rfloor$ is the largest integer not greater than $x$.  It is said this problem was created by Paul Erdős, and I can't find this problem's solution, does anyone have any nice methods? Thank you. Why doesn't the Moon fall onto the Earth? What is an intuitive way of understanding Ostrogradsky instability? Is there a way of explaining why no differential equations in physics exceed order two without delving into Lagrangian and Hamiltonian mechanics - i.e. from Newtonian mechanics? Moreover, is there such an alternative proof, which focuses more on physical reasoning than abstract mathematics?
