You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '} WHERE id = 1' at line 4)
The question is really broad and so opinionated.
For the server-side I prefer F# due to mature .NET Core framework and functional defaults. Although the choice here is huge: js, C#, Java, Ruby, PHP, Go, Erlang. Literally, everything that is suitable for your specific needs.
But if you project needs super-fast responses from Backend, so choose another language more powerful like Golang or Java, if not go with nodejs.
My website, www.maroisconsulting.com, is hosted on Arvixe. I would like to create a folder, put some files in it, then allow an app I'm working on the download the files. I've never done this before and I'm stuck
Here's my download code so far.
static WebClient wc;
staticvoid Main(string args)
var fileUrl = "http://" + "www.maroisconsulting.com/SomePlace/SomeFile.txt"; // Broke it up so it would format here
wc = new WebClient();
wc.DownloadProgressChanged += Wc_DownloadProgressChanged;
wc.DownloadFileCompleted += Wc_DownloadFileCompleted;
wc.DownloadFileAsync(new Uri(fileUrl), @"c:\files\SomeFile.txt");
privatestaticvoid Wc_DownloadFileCompleted(object sender, System.ComponentModel.AsyncCompletedEventArgs e)
Console.WriteLine("The download has been cancelled");
if (e.Error != null)
Console.WriteLine("An error ocurred while trying to download file" + Environment.NewLine + e.Error.Message);
Console.WriteLine("File succesfully downloaded");
privatestaticvoid Wc_DownloadProgressChanged(object sender, DownloadProgressChangedEventArgs e)
Console.WriteLine(e.ProgressPercentage + "% | " + e.BytesReceived + " bytes out of " + e.TotalBytesToReceive + " bytes retrieven.");
When I run, the Wc_DownloadFileCompleted fires immediately with the error
The remote server returned an error: (404) Not Found.
When I go in to the Arvixe Control Panel, File Manager, for my site, the file does exist. Again, this is new to me so I am probably doing something wrong.
Can anyone show me how this is done?
If it's not broken, fix it until it is.
Everything makes sense in someone's mind.
Ya can't fix stupid.
I am working on a browser-based document scanning application for IE it is fine as we can do scanning through ActiveX or Add-ons etc but when it comes to modern browsers like latest chrome, firefox and edge it is very hard to call any .exe or other is related functions from client-side .. What is the option to invoke scanner from modern browsers and do necessary file I/o on client end... Please don't mention proprietary software I prefer to work with open-source solutions.. regard
I'm a language teacher, which means no programming or coding skills, but eager to learn.
I've spent the past day or two learning on how to create a website, domains, hosting and all that and there are a lot of tutorials on how to use WordPress and plug-ins like the Elementor which is quite easy to use and doesn't require much coding knowledge. Most of them focus on how to make stuff pretty and I got that part.
What do I need to use to create a database, so that people can register and then they get assigned an educational package based on their choosing or a diagnostic test. My web-page won't be that much complicated regarding graphics, but I am going to use a lot of layers, and it would be great if a person could log-in and continue where he stopped, if the page tracked his results, etc. Could somebody point me in the right direction, which tools do I need to use? Are there any tools like WordPress for this type of programming?
I would suggest you make use of the Wordpress helpline, as they are best placed to advise you what tools are available for your specific needs. They may well have some off the shelf back end system which would provide for your database needs, without you needing to hire a database programmer to do it for you.
I have never used Wordpress before so I could be wrong.
If I understand correctly, MySQL is the core of Wordpress so you already have a database, you will have to find a plugin to save your data to the database, I have found one on google but you will have to pay for it. You can do it yourself but it will require you to learn PHP and SQL.
To create and maintain a computer database, you need a database program, often called a database management system, or DBMS. Just as databases range from simple, single-table lists to complex multi-table systems, database programs, too, range in complexity.

I made a pool 8 ball, in nodejs where 2 players put some amount of money to the server before playing, the server where they send money to my paypal account using the client id and secret, but if a player wins he must earn (his money + the oponent money - as_server_I_take_some); so how can I send money to the winner, is there any implementation or transaction to be saved (I use node js paypal rest sdk).
