Newbe Dev Stack

Answer : ArtiomLK Suggested a solution in comments which helped me: wrap SingleChildScrollView in a Center . The widgets tree is: Center( child: SingleChildScrollView( child: Column(...))) None of the others helped. Solution: Put your top level Stack inside Center widget. body: Center(child: Stack( children: _buildBody(), ))); Tip to debug: Use Flutter Inspector to find where the layout is going wrong. I edited your code a bit(to make to work in my local) and then I inspected. It showed like below We have a Stack and SingleChildScrollView as per code(refer right side of the diagram where the stack of widgets are displayed). As size is determined by SingleChildScrollView (contents inside it), Stack occupies only little space and by default, it aligned at top . So put it under Center , the whole Stack view will come in center. There's a section about it in the official docs: Using SingleChildScrollView with a Column Source: https://api....

Answer : The grid tile component sets top padding dynamically on the element itself, so you need to use the !important modifier in your CSS to override it. HTML: <mat-grid-tile class="my-grid-tile"></mat-grid-tile> CSS: .my-grid-tile { padding-top: 24px !important; } Setting rowHeight of mat-grid-list works for me, the G. Tranter doesn't work because the mat-grid-list has a padding It's set dynamically too and cannot be setted with !important. <!-- 70px to prevent hide floatLabel in matInput --> <mat-grid-list cols="2" rowHeight="70px"> <mat-grid-tile> <!-- your controls --> </mat-grid-tile> </mat-grid-list> Ref: https://material.angular.io/components/grid-list/examples "@angular/material": "^6.4.3" "@angular/core": "^6.1.0" To get rid of the padding on top of mat grid tile restrict the height of the mat grid tile usi...

Answer : Try adding a label attribute to the inputText field - if there is no label, the error will display the whole tree, but with a label, it should just display the label + error message

Answer : There is no problem with your web.config . Your web site runs under a process. In iis you can define the identity of that process. The identity that your web site's application pool runs as ( Network Services, Local System , etc.), should have permission to access and read web.config file. Update: This updated answer is same as above, but a little longer and simpler and improved. First of all : you don't have to change anything in your config file. It's OK . The problem is with windows file permissions . This problems occurs because your application can not access and read web.config file. Make the file accessible to IIS_IUSRS group. Just right click web.config and click properties , under security tab, add IIS_IUSRS . So what is this IIS_IUSRS thing? Your web site is like an exe file. Just like any exe file, it should be started by a user and it runs according to permissions assigned to that user. When your site is started in IIS , A...

Answer : I think you are talking about padding strings with spaces. One way to do this is with string format codes. For example, if you want to pad a string to a certain length with spaces, use something like this: String padded = String.format("%-20s", str); In a formatter, % introduces a format sequence. The - means that the string will be left-justified (spaces will be added on the right of the string). The 20 means the resulting string will be 20 characters long. The s is the character string format code, and ends the format sequence. There's a few approaches for this: Create a char array then use Arrays.fill, and finally convert to a String Iterate through a loop adding a space each time Use String.format

Answer : I suggest to use another then instead of using finally . then after catch is works like a finally . don't forget to use at least one catch in your promise chain, in order to handle your instructions failure. So this two line of code is the same: api.get(…).then(…).catch(…).then(...) and api.get(…).then(…).catch(…).finally(...) Only a native Promise (constructed with new Promise ) is guaranteed to have a .finally method (in newer environments). (in older environments, .finally won't work at all with Promises created with new Promise ) It looks like axios doesn't use new Promise internally - rather, it just returns a thenable, which is not guaranteed to have a finally method (and because it doesn't, it throws an error). While you could use the explicit Promise construction antipattern to wrap the axios call in a native new Promise , so that it has Promise.prototype.finally in its prototype chain, a better option (thanks Bergi!) is to just...

Answer : The solution proposed here worked for me: Java Intent i = new Intent(OldActivity.this, NewActivity.class); // set the new task and clear flags i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK); startActivity(i); Kotlin val i = Intent(this, NewActivity::class.java) // set the new task and clear flags i.flags = Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_CLEAR_TASK startActivity(i) However, it requires API level >= 11. Here is one solution to clear all your application's activities when you use the logout button. Every time you start an Activity, start it like this: Intent myIntent = new Intent(getBaseContext(), YourNewActivity.class); startActivityForResult(myIntent, 0); When you want to close the entire app, do this: setResult(RESULT_CLOSE_ALL); finish(); RESULT_CLOSE_ALL is a final global variable with a unique integer to signal you want to close all activities. Then define every activity's onActivityRe...

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...

Answer : The following example shows how to add support to the SystemTextJsonInputFormatter for handling additional media-types: services.AddControllers(options => { var jsonInputFormatter = options.InputFormatters .OfType<SystemTextJsonInputFormatter>() .Single(); jsonInputFormatter.SupportedMediaTypes.Add("application/csp-report"); }); This is a two-step process: Interrogate the configured list of input-formatters to find the SystemTextJsonInputFormatter . Add application/csp-report to its existing list of supported media-types ( application/json , text/json , and application/*+json ). If you're using Json.NET instead of System.Text.Json , the approach is similar : services.AddControllers(options => { var jsonInputFormatter = options.InputFormatters .OfType<NewtonsoftJsonInputFormatter>() .First(); jsonInputFormatter.SupportedMediaTypes.Add("application/csp-report"); }) T...

Answer : This may be a bit of a workaround - but the font is very similar to Bitstream Vera Sans Mono. Here is a comparison ( updated link ) of Menlo and Bitstream Vera Sans Mono DejaVu Sans Mono (also based on Bitstream's original). You can download the Bitstream set absolutely free (zip file). this font https://github.com/andreberg/Meslo-Font is designed to be similar to Menlo I have found a github repo.

Answer : In my case, the tools folder didn't exist inside %USERPROFILE%\.dotnet\ so I had to run the command dotnet tool install --global dotnet-ef to install dotnet ef. Then I was able to run dotnet ef... This was the result of the above install command: Note to readers: If you haven't installed dotnet ef , you need to install it first: dotnet tool install --global dotnet-ef . The question-asker already did that. You need to do that first before the rest of this answer can help. How to fix this For Linux and macOS , add a line to your shell's configuration: bash / zsh : export PATH="$PATH:$HOME/.dotnet/tools/" csh / tcsh : set path = ($path $HOME/.dotnet/tools/) When you start a new shell/terminal (or the next time you log in) dotnet ef should work. For Windows : See this question on how to add to the PATH environment variable. You need to add %USERPROFILE%\.dotnet\tools to the PATH . What's going on? The .NET Core 3.0 (preview) ...

Answer : Backup window doesn't specifically ask for the time when to start take backup but instead ask for time period in which aws can trigger backup. So basically it's asking for backup window time . That's why it has 2 fields 1. StartTime: When can the process of backup be started. 2. Duration : time window in which process must start to take backup. E.G if I set start time: 5:30 and duration: 30mints Backup can start at anytime between 5:30 to 6:00 . from Working With Backups documentaion Below is the answer for "what if the backup did not fit into a backup window?" If the backup requires more time than allotted to the backup window, the backup continues after the window ends, until it finishes. Below is the answer for "If backup may not fit into the backup window, why do we need a backup window?" The backup window can't overlap with the weekly maintenance window for the DB instance.
