Sorry about this dumb question, but i´ve recently found out that you can declare a String or string variable at C#. I would like to know the difference between them, which one is used at specific situations, etc. Thanks for the help and for your time.
Example (note the case):  string s = "Hello world!"; String s = "Hello world!";   What are the guidelines for the use of each? And what are the differences?
How can I check if share certificates I found have value? I have been clearing my parents flat and found share certificates from    P and O  European Ferries   Can I find out if they are still valid? If not, is there a market for them as collectibles or the like? What is PECS (Producer Extends Consumer Super)? Can I see why a package is installed? Where do I get the key for the first house? I've 'completed' the game, but didn't find the key for the first house. (I got the one for the arcade machine house). Where can I find it? Change font of formula number in DisplayFormulaNumbered It is stated that if $\psi(x_0)=\psi'(x_0)=0$ at some $x_0$, then $\psi(x)=0,\forall x$.  Hence, we cannot have the wavefunction and its derivative vanishing at the same point.  My question is, how to prove the above statement? Can you flash any android device with "fastbood flash" command (of the adb)? i want to create new event in SharePoint calendar list in which I have some custom columns,i tried below code but it is not working      function bookingRoomForMeeting() {         var ctx = new SP.ClientContext(appWebUrl);//Get the SharePoint Context object based upon the URL           var list = ctx.get_web().get_lists().getByTitle("MyCalendarList"); //Get the List based upon the Title         var listCreationInformation = new SP.ListItemCreationInformation(); //Object for creating Item in the List         listItem = list.addItem(listCreationInformation);         listItem.set_item('Title', $("#txt_Title").val());         var date = $("#txt_startTime").val();         var dateTime = moment(date, 'DD/MM/YYYY HH:mm a').format("MM/DD/YYYY HH:mm a");         listItem.set_item('EventDate', dateTime);         var enddate = $("#txt_endTime").val();         var enddateTime = moment(enddate, 'DD/MM/YYYY HH:mm a').format("MM/DD/YYYY HH:mm a");         listItem.set_item('EndDate', enddateTime);         listItem.set_item('EmailId1', $("#txt_EmailId1").val());         listItem.set_item('EmailId2', $("#txt_EmailId2").val());         listItem.update();         ctx.load(listItem);         ctx.executeQueryAsync(             Function.createDelegate(this, success),             Function.createDelegate(this, fail)            );     } function success() {     alert("Completed"); } function fail() {     alert("operation failed"); }   list am using is SharePoint hosted app list,can any one tell me where am going wrong? What's the past participle form of the word exit? Is it exit (irregular, like set)? exited? exitted? On one page I found exited but if that's the case why isn't it exitted (double t) like with the word emit - emitted? Is there a rule when the consonant at the end is doubled and when not? no match for ‘operator<<’ in ‘std::operator Where to get the full offline-capable installer for macOS Mojave (.1 update)? I'm not entirely clear on how Counterspell works, when trying to counter higher-level spells: the CS description only talks about disrupting a creature you can see, within 60 feet, casting a spell.   However, when trying to counter a higher level spell:   Do I know what spell is being cast?  Do I at least know (somehow intuit, based on VSM components) the level of the spell? Or can I tell the spell/level of the spell by sensing a disturbance in The Weave? (I.e., if the spell is being cast using Subtle Spell, can I still tell what's going on?)   The point of the question is to determine how fruitful CS can be in combat--if I know what the other guy/gal is casting (or at least the level), I can decide whether I want to spend my L8 slot to counter his/her L8 slot. But if I have no idea, and I end up using a L8 slot to counter a L3 spell... seems a bit painful.  Hope this made sense! Finite subgroups of the multiplicative group of a field are cyclic In Grove's book Algebra, Proposition 3.7 at page 94 is the following     If $G$ is a finite subgroup of the multiplicative group $F^*$ of a field $F$,   then $G$ is cyclic.   He starts the proof by saying "Since $G$ is the direct product of its Sylow subgroups ...". But this is only true if the Sylow subgroups of $G$ are all normal. How do we know this? if command in find -exec I was just trying to list all directories and files under current directory and also write if they are file or directory with the following command:  find -exec echo `echo {} : ;if [ -f {} ]; then echo file; else echo directory;fi` \;   I know it is a silly command, I can use other things like -type f or -type d, but I want to learn why that piece of code did not work as I expected. It just prints directory to all of them. For example while output of find is:  . ./dir ./dir/file   output of my code is :  . : directory ./dir : directory ./dir/file : directory   And output of   echo `echo dir/file : ;if [ -f dir/file ]; then echo file; else echo directory;fi`   is  dir/file : file   I am working on Ubuntu 14.10 and using find (GNU findutils) 4.4.2 I know that the movies were written to be a stand alone universe on their own, but what key elements were missing in the movies that were vital in the books that viewers are missing out on? Sharepoint 2010 - Deploy webpart as Feature scope = web I want to create and deploy a web part as web-scoped feature.  In Visual Studio 2010, when I make the feature scope=web, I cannot add the webpart to that feature as I am able to do when scope=site. Unity-like Dashboard for Gnome fallback? Is there any way I can run the Unity dashboard (or something similar, like Bolt for Gnome 3) in Gnome Fallback? Accumulation Points for $S = \{(-1)^n + \frac1n \mid n \in \mathbb{N}\}$ I was recently asked to find the accumulation points of the set $$S = \{(-1)^n + \frac{1}{n} \mid n \in \mathbb{N}\}$$  I answered that the accumulation points are $\{-1,1\}$, because despite the fact that $\frac{1}{n}$ diverges, we can still use $\frac{1}{n}$ to find an element arbitrarily close to either $1$ or $-1$, i.e. to show that there is an element in an arbitrarily small neighborhood of $1$ or $-1$. (No proof was required for this question --- this is my intuition.)  Am I right at all? Limit $\frac{x^2y}{x^4+y^2}$ is found using polar coordinates but it is not supposed to exist. How do I choose grid and block dimensions for CUDA kernels?
