Answer : I'll give you the basics. In Angular Material (for Angular 2/4) the most commonly used attributes are: fxLayout="row | column" fxLayoutAlign="start | center | end | stretch | space-around | space-between | none" (can accept 2 properties at the same time) fxFlex="number" (can accept numbers from 1 to 100) You can also use postfix as fxLayout.xs and so on to apply rules only for specific resolution. For more info you can look through the docs: https://github.com/angular/flex-layout/wiki/API-Documentation To play around with alignment, you can use the demonstration from Angularjs Material resource (it's totally the same as for Angular Material for Angular 2/4): https://material.angularjs.org/latest/layout/alignment And another one useful link: https://tburleson-layouts-demos.firebaseapp.com/#/docs

Example: from logging import logger # ! / usr / bin / env python3 # - * - coding : UTF - 8 - * - import logging logger = logging . getLogger ( __name__ ) logging . basicConfig ( level = logging . DEBUG ) logger . debug ( 'Loging %s lewel' , 'DEBUG' ) logger . info ( 'Loging %s lewel' , 'INFO' ) logger . warning ( 'Loging %s lewel' , 'WARN' ) logger . error ( 'Loging %s lewel' , 'ERROR' ) logger . critical ( 'Loging %s lewel' , 'CRITICAL' )

Answer : The easiest solution is probably to create a custom UnderLineTextView component deriving from TextView, override setText() and set the entire text as underlined, something like this (underline code from the link you referred to above): @Override public void setText(CharSequence text, BufferType type) { // code to check text for null omitted SpannableString content = new SpannableString(text); content.setSpan(new UnderlineSpan(), 0, text.length(), 0); super.setText(content, BufferType.SPANNABLE); } It's then just a matter of using your new component in the layout and setting the text as usual. The rest is handled automatically. More info on custom components: http://developer.android.com/guide/topics/ui/custom-components.html You can underline text over Html.fromHtml(String source) Example: textView.setText(Html.fromHtml("this is <u>underlined</u> text"));

Answer : I needed to perform a batch update inside a transaction (I didn't want to have partial updates in case something went wrong). I've resolved it the next way: // I wrap knex as 'connection' return connection.transaction(trx => { const queries = []; users.forEach(user => { const query = connection('users') .where('id', user.id) .update({ lastActivity: user.lastActivity, points: user.points, }) .transacting(trx); // This makes every update be in the same transaction queries.push(query); }); Promise.all(queries) // Once every query is written .then(trx.commit) // We try to execute all of them .catch(trx.rollback); // And rollback in case any of them goes wrong }); You have a good idea of the pros and cons of each approach. I would recommend a raw query that bulk updates over several async updates. Yes you can ru

Answer : assuming you are using latest stable version of material 2, you can use floatLabel="never" to force label to not to float. here is live working demo this is clear in documentation https://material.angular.io/components/form-field/api <form class="search-form"> <mat-form-field class="example-full-width" appearance="standard"> <input class="toolbar-search" type="text" matInput> <mat-placeholder>Search</mat-placeholder> <mat-icon matSuffix style="font-size: 1.2em">search</mat-icon> </mat-form-field> </form> Please set the appearance of mat-form-field to standard and the placeholder will stop behaving like label. Explanation : By default the mat-label in mat-form-field floats and the appearance of mat-form-field is "legacy". That means if a mat-label is not present with the form field then placeholder will start behavin

Answer : SQL Server does not currently support subqueries for CHECK CONSTRAINTs. As you have discovered, there can be trouble with CHECK constraints involving UDFs when attempting to circumvent the subquery limitation. The alternative constraint implementation strategies are triggered procedural and embedded procedural . The former is preferred because, in common with declarative constraints, they cannot be circumvented. Implementing a triggered procedural strategy that is well optimized and handles concurrency issues is non-trivial but still doable. I highly recommend the book Applied Mathematics for Database Professionals By Lex de Haan, Toon Koppelaars, chapter 11 (the code examples are Oracle but can be easily ported to SQL Server). As others have mentioned already, this type of Check constraints is not yet implemented in SQL-Server. Besides triggers, you could also examine the possibility of changing the table's design. A possible alternative includes storing the

Answer : What duncan said: What you want to do is add all your markers to an array. In your click event handler, loop over that array, updating each marker's icon. Then finally set the icon for just the marker that's been clicked. google.maps.event.addListener(marker, 'click', (function (marker, i) { return function () { infowindow.setContent(locations[i][0], locations[i][6]); infowindow.open(map, marker); for (var j = 0; j < markers.length; j++) { markers[j].setIcon("https://cdn3.iconfinder.com/data/icons/musthave/24/Stock%20Index%20Up.png"); } marker.setIcon("https://cdn3.iconfinder.com/data/icons/musthave/24/Stock%20Index%20Down.png"); }; working fiddle working code snippet: var markers = []; var map; function initialize() { map = new google.maps.Map(document.getElementById('map'), { zoom: 12, // center: new google.maps.LatLng(-33.92, 151.25), center: new google.maps.LatLng(36.8857, -7
