Answer : Move the cursor to the line from where you want to copy and paste contents at another place. Hold the key v in press mode and press upper or lower arrow key according to requirements or up to lines that will be copied. you can press key V to select whole lines. Press d to cut or y to copy. Move the cursor to the place where you want to paste. Press p to paste contents after the cursor or P to paste before the cursor. You have :set paste Put Vim in Paste mode. This is useful if you want to cut or copy some text from one window and paste it in Vim. This will avoid unexpected effects. Setting this option is useful when using Vim in a terminal, where Vim cannot distinguish between typed text and pasted text. Assuming your vi is actually vim, before pasting, do: :set paste That disables word wrapping and auto-indent and all similar things that modify typed text. After pasting, tur

Answer : No. That's why it is called MySQL Workbench. The reason is that the MWB uses a lot of MySQL specific functionality. I don't think there is currently something similar for Postgres, but you could try Glom or pgadmin3. A company-independent database manager is the commercial Aqua Data Studio - maybe it's worth a try.

Answer : Personally, I prefer this syntax for appending options: $('#mySelect').append($('<option>', { value: 1, text: 'My option' })); If you're adding options from a collection of items, you can do the following: $.each(items, function (i, item) { $('#mySelect').append($('<option>', { value: item.value, text : item.text })); }); This did NOT work in IE8 (yet did in FF): $("#selectList").append(new Option("option text", "value")); This DID work: var o = new Option("option text", "value"); /// jquerify the DOM object 'o' so we can use the html method $(o).html("option text"); $("#selectList").append(o); You can add option using following syntax, Also you can visit to way handle option in jQuery for more details. $('#select').append($('<option>', {value:1, text:'One'}

Answer : You can do this using the class binding: <input type="email" class="form-control" [class.error-field]="error"> yeah there's a better way using ngClass attribute like this: <input type="email" [ngClass]="{'form-control': true, 'error-field': error}" /> I believe you are looking for NgClass or NgStyle: https://angular.io/api/common/NgClass https://angular.io/api/common/NgStyle

Answer : If you are getting this error on Ionic2 This issue generally occur when we just clone / download app and try to add platform to it. its very easy to resolve, then here are the steps- just create a "www" directory in application root. "./www" can also do by this command- mkdir www now we can easily run following command - ionic platform add android or ionic platform add ios Hope it will help!!! Solution is to make sure there's a www/ directory inside the root directory. mkdir www make sure your .gitignore file doesn't include www/ directory on it. Yes, as QuickFix said, you need to be in a Cordova project before being able to use most of cordova Commands. If you are curious about what defines a Cordova project, this is what I found: Has a .cordova directory, with a config.json inside. Has a www directory, with a config.xml inside. Has a platforms directory. With that in place you can use Cordoba commands without problem. If you need examples o

Answer : If the file is called configure.ac, do $> autoconf Depends: M4, Automake If you're not sure what to do, try $> cat readme They must mean that you use "autoconf" to generate an executable "configure" file. So the order is: $> autoconf $> ./configure $> make $> make install The failsafe for generating a configure script is autoreconf -i , which not only takes care of calling autoconf itself, but also a host of other tools that may be needed. It's just problem with permissions Run chmod +x ./configure Should work

Answer : These general steps were helpful for me to resolve similar issues: Use Hoogle or Stackage to find the package where the module resides Note that Hoogle and Stackage are case-sensitive . Looking up Data.Map in Hoogle yields a list similar to the one below. Stackage has a slightly different style, but the basics are the same (mostly because it also uses Hoogle for lookup). The lines in green under the result headings show the name(s) of the containing (1) package(s) (in small caps) and (2) module(s) (capitalized). Open project-name.cabal in project root and add required package under build-depends: library hs-source-dirs: src build-depends: base >= 4.7 && < 5 , containers exposed-modules: Lib Issue stack build to download and build dependencies (or stack ghci if you plan to use it in the REPL) The reason you can import Data.Char and Data.List is that they are part of the package base , which is included with GHC and is always

Answer : A URL that was created from a JavaScript Blob can not be converted to a "normal" URL. A blob: URL does not refer to data the exists on the server, it refers to data that your browser currently has in memory, for the current page. It will not be available on other pages, it will not be available in other browsers, and it will not be available from other computers. Therefore it does not make sense, in general, to convert a Blob URL to a "normal" URL. If you wanted an ordinary URL, you would have to send the data from the browser to a server and have the server make it available like an ordinary file. It is possible convert a blob: URL into a data: URL, at least in Chrome. You can use an AJAX request to "fetch" the data from the blob: URL (even though it's really just pulling it out of your browser's memory, not making an HTTP request). Here's an example: var blob = new Blob(["Hello, world!"], { type: 'text/plain

Answer : Angular 2 Style Guide According to the official Angular 2 style guide, STYLE 05-12 says Do use @Input and @Output instead of the inputs and outputs properties of the @Directive and @Component decorators The benefit is that (from the guide): It is easier and more readable to identify which properties in a class are inputs or outputs. If you ever need to rename the property or event name associated with @Input or @Output , you can modify it a single place. The metadata declaration attached to the directive is shorter and thus more readable. Placing the decorator on the same line makes for shorter code and still easily identifies the property as an input or output. I've personally used this style and really appreciate it helping keep the code DRY. One of the cool thing that I know you can do with decorators but I'm not if it's possible with the other way, is aliasing the variable: export class MyComponent { @Output('select') $onSelec

Answer : A clear explanation from Daniel Irvine: There's a problem with 401 Unauthorized , the HTTP status code for authentication errors. And that’s just it: it’s for authentication, not authorization. Receiving a 401 response is the server telling you, “you aren’t authenticated–either not authenticated at all or authenticated incorrectly–but please reauthenticate and try again.” To help you out, it will always include a WWW-Authenticate header that describes how to authenticate. This is a response generally returned by your web server, not your web application. It’s also something very temporary; the server is asking you to try again. So, for authorization I use the 403 Forbidden response. It’s permanent, it’s tied to my application logic, and it’s a more concrete response than a 401. Receiving a 403 response is the server telling you, “I’m sorry. I know who you are–I believe who you say you are–but you just don’t have permi

Example: virtual memory in os Virtual Memory is a storage mechanism which offers user an illusion of having a very big main memory . It is done by treating a part of secondary memory as the main memory . Therefore , instead of loading one long process in the main memory , the OS loads the various parts of more than one process in the main memory .

Answer : NumberPicker is not just for integers.. Even you can use Floats String etc. see this and read about it. for tutorials : http://gafurbabu.wordpress.com/2012/03/29/android-number-picker-dialog/ And I had used NumberPicker long ago like this and it might be some use posting here: NumberPicker np; String nums[]= {"Select Fraction","1/64","1/32","3/64","1/16","5/64","3/32","7/64","1/8","9/64","5/32","11/64","3/16","13/64","7/32","15/64","1/4","17/64","9/32","19/64","5/16","21/64","11/32","23/64","3/8","25/64","13/32","27/64","7/16","29/64"}; np = (NumberPicker) findViewById(R.id.np); np.setMaxValue(nums.length-1); np.setMin

Answer : The pattern is not correct as a string. In deed you are inside a string so to escape '.' you need to use double backslash like: emailRegEx = '^[a-z0-9._%+-]+@[a-z0-9.-]+\\.[a-z]{2,4}$' Or if you want to avoid doing so i suggest to use: emailRegEx = /^[a-z0-9._%+-]+@[a-z0-9.-]+\.[a-z]{2,4}$/ Edit: Keep in mind that this is a simple pattern that exclude a lot of valid email address (see RFC 5322 (sections 3.2.3 and 3.4.1) and RFC 5321). For example the angular build in email validator use the following pattern /^(?=.{1,254}$)(?=.{1,64}@)[-!#$%&'*+/0-9=?A-Z^_`a-z{|}~]+(\.[-!#$%&'*+/0-9=?A-Z^_`a-z{|}~]+)*@[A-Za-z0-9]([A-Za-z0-9-]{0,61}[A-Za-z0-9])?(\.[A-Za-z0-9]([A-Za-z0-9-]{0,61}[A-Za-z0-9])?)*$/
