"On Exit" for a Console Application I am looking for a way to trigger a piece of code when a console application is manually closed (users closes window). Been trying with:  AppDomain.CurrentDomain.ProcessExit +=     new EventHandler(CurrentDomain_ProcessExit);   but the above doesn't work if manually closed.  Is there any ways to use a .Net call for this or do I need to import the Kernel dll and do it that way?
Capture console exit C# I have a console application that contains quite a lot of threads.  There are threads that monitor certain conditions and terminate the program if they are true.  This termination can happen at any time.  I need an event that can be triggered when the program is closing so that I can cleanup all of the other threads and close all file handles and connections properly.  I'm not sure if there is one already built into the .NET framework, so I'm asking before I write my own.  I was wondering if there was an event along the lines of:  MyConsoleProgram.OnExit += CleanupBeforeExit;
Removing small spaces (slivers) between polygons? I have a Dedicated Bedrock Server running on my PC, and I can't connect from the same PC where the server is. If I add it onto the list of servers, it appears as "Locating server" and never finds it.    If I try to connect, I get "Unable to connect to world".    On my friend's PS4, it appears on the Friends tab as a LAN Game on a Dedicated Server.    And also on my sister's laptop. The plot is simply that aliens visit Earth and their interest in collecting cow pies (and just like other collectibles, special attributes make them more valuable) creates interest in humans in obtaining them to sell. Then the aliens leave and the market plummets. I do not recall the name of the story and also at the end I think some new object is of interest which maybe someone remembers. As silly as the premise sounds, if you look at what people really do collect and the amazing prices, the story kind of resonates. Digital crypto-kitties or whatever and more recent things selling for tens of millions or cryptocurrencies themselves seem not so different than cow pie collecting. Moreover, the fundamental theorem of collectibles is that to make a huge amount, paradoxically the collectible had to not only start out as more or less worthless but also something people tended to use/read and then destroy or at least throw away. Old Nat Geo magazines are worth almost nothing because everyone kept them; Action Comics #1 on the other hand, well moms could not wait to toss those when their son went away to college or got married. The stories I have in just my own family. Why is the node editor showing different kinds of nodes? I can't figure out how to turn on the Bluetooth on my Nikon D5600. I have updated the firmware to the latest 1.01 and still the same problem.   Bluetooth is dimmed out on the camera and will not turn on. I get an error message saying, "This option is not available at current settings or in the camera's current state".  I have tried everything I can think of and no go. I can't find help for this problem anywhere on the internet and still no reply from Nikon.  How do I turn on my camera's Bluetooth? The Challenge  I have been trying to write a filter that applies (prepends a string) to (a) post titles of a certain post type and (b) to that same post type WordPress admin backend for use by an auto social sharing plugin.  I've gotten really close.  I've achieved: 1.  prepending only to custom post_type post titles 2.  prepending to custom_post type titles AND all nav menu items 3.  prepending to ALL titles (post, page, nav menu, and backend auto-sharing plugin)  The final, 3rd attempt got me very hopeful, but yet still, no matter the function, conditional statement, or combination I use, I can't get custom_post title AND backend social sharing plugin, but not nav menu items.  My Code - what I've tried  I've tried different conditionals, like is_admin() and !is_nav_menu with all nav menu IDs.  I've also tried comparing the ID of the post to the ID of the menu.  Finally, I've also tried adding the filter only to loop_start and that seems promising if combined with other statements.  I will clean up my code for your review but I leave it this way for now in hopes it helps to see what I've tried and maybe where I went wrong with any of those methods.  // , $id = NULL function append_album_review_to_title( $title ) {     global $post;     global $dont_apply_title_filter;     $text = 'Album Review: ';     $prepended_title = $text . $title; /*     $nav_menus_obj = wp_get_nav_menus();     $nav_menu_ids = '';     foreach( $nav_menus_obj as $nav_menu ) {         $nav_menu_ids .= $nav_menu-&gt;term_id .

They are pronounced differently based on whether they are a noun or a verb.  Here are the terms I DON'T think would apply:   Homograph: same spelling, different meanings: for example, bark (the sound of a dog) and bark (the skin of a tree). Homophone: same pronunciation, different meaning: for example, to and two Homonym: same pronunciation and spelling, different meanings: for example: bank (river bank or savings bank) Heteronym: same spelling,  different pronunciations and meanings: for example bow (the front of a ship) and bow (a ranged weapon)   Bow is particularly interesting. It is a heteronym based on the two nouns I described. But in the sense of the body movement, the noun and the verb are pronounced alike (rhyming with wow), thus, not belonging to the category I've explained.  In fact none of the terms explained  satisfy my requirement.  I'm looking for the term for words that have same (or related at best, NOT different) meanings, same spelling and different pronunciation.  Specifically, different pronunciation depending on the part of speech. As against the words which have the same pronunciation in different parts of speech like bill, turn, case (or bigger ones like manoeuvre)  TL;DR:  Fill in the blank:     The noun and verb forms of construct are pronounced differently   because the word construct is a _____   or      The noun and verb forms of construct are pronounced differently   because they are _____s. Access Java / Servlet / JSP / JSTL / EL variables in JavaScript Number of permutations of $n$ elements where no number $i$ is in position $i$ I know that RAM disks are fast, faster than any disk, but they lose their contents on a shutdown of the operating system. The capacity is limited to the RAM. Is there a useful implementation on a new 64-bit Windows 2008 server? The question is $$\text{If }\, p, \ q\in \mathbb{N}, \;1-\frac12+\frac13-\frac14-\dotsb-\frac{1}{1318}+\frac{1}{1319}=\frac{p}{q}.\qquad \text{Prove that } 1979\mid p.$$ So my solution went like this:  $$S=1-\frac12+\frac13-\frac14-\dotsb-\frac{1}{1318}+\frac{1}{1319}\Rightarrow S=\sum_{k=1}^{1319}\frac{1}{k}-2\sum_{k=1}^{659}\frac{1}{2k}=\sum_{k=660}^{1319}\frac{1}{k}$$ Now this is equivalent to finding the sum of the roots of the equation $$\left(x-\frac{1}{660}\right)\left(x-\frac{1}{661}\right)\dots \left(x-\frac{1}{1319}\right)=0$$. Rewriting this equation, we get $(660x-1)(661x-1)\dotsc(1319x-1)=0$ (we can discard the $\displaystyle \frac{1319!}{659!}$ since $1979$ is a prime). Calculating the sum of the roots, we get the required value to be equal to $(1320+659)\times 330$ which is obviously divisible by $1979$ (again discarding the coeffecient of $x^{660}$).  Now my question is: Using the same method of converting the problem into finding the sum of roots of a polynomial, we get from the original equation something like this: $$(x-1)\left(x+\frac{1}{2}\right)\dots \left(x-\frac{1}{1319}\right)=0 \Rightarrow (x-1)(2x+1)\dotsc(1319x-1)=0$$ So, the sum of roots would be $-1+2-3+4-\dotsc+1318-1319=-660$ But this is not divisible by $1979$. Why does the former solution work while the latter doesn't? Is there a flaw in my reasoning? Note: I know that the question can be solved by some other methods. Please only explain my given doubts and don't instead give another solution  I realised my mistake after some hours of pondering over it. (In the 1st equation) To get the required sum I would need to take calculate $\displaystyle -\frac{\text{coeffecient of }x^{659}\,}{\text{coeffecient of }x^{660}}$. However what I've done is calculate this:  $\displaystyle -\frac{\text{ coeffecient of }x}{\text{coeffecient of }x^{660}}$ which is actually equal to $\text{sum of roots taken }659 \text{ at a time} $. It was just a coincidence that the value I calculated was divisible by $1979$. The correct way, indeed, would be through the link supplied Curve Bevel function, scale? Why would layout_width="wrap_content" take up the entire width of the screen? This is a batch file in Windows.  Here is my .bat file          @echo off copy "C:\Remoting.config-Training" "C:\Remoting.config"  "C:\ThirdParty.exe"   This works fine except the .bat file leaves the command window open the whole time the "ThirdParty" application is running. I need the command window to close.   I would use the short-cut for the application but I must be able to run this copy command first (it actually changes which data base and server to use for the application).    The ThirdParty application does not allow the user to change the source of the db or the application server.    We're doing this to allow users to change from a test environment to the production environment. Mobile web refresher, part 3 The meaning of imaginary time What is imaginary (or complex) time? I was reading about Hawking's wave function of the universe and this topic came up. If imaginary mass and similar imaginary quantities do not make sense in physics, why should imaginary (or complex) time make sense?    By imaginary I mean a multiple of $i$, and by complex I mean having a real and an imaginary part, i.e., $\alpha + i\beta$, where $\alpha, \beta \in {\mathbb R}$. Existence of subgroup of order six in $A_4$ Show that  the  alternating  group  $A_4$  of all even permutations of $S_4$ does not contain a  subgroup of order $6$.   For me am thinking to write all elements of $A_4$ and trying to find every cyclic subgroup generated by each element of $A_4$, then I have to check whether there exist such a subgroup or not! This is a long procedure for me, I ask if there is a short way to do this. I constantly stay up to date with each new release of Blender, but this means my preferences are wiped clean each time. How do I export/import these preferences to avoid loosing my carefully crafted set up each time?
