How to Connect Xamarin Forms to MySQL database as backend of the app without webservice?
i'm using a control panel website called myasp.net it offers a MySQL online database , and here's my phpMyAdmin i already set up all of the tables i needed, and i want to connect it to my xamarin forms application directly. is it possible?
I think your question also goes somewhat like this one I answered, and you are asking so many things with very few lines.
is it possible Xamarin.Forms Android and iOS with Sqlite syncing to MySql?
again, you need to create an API to reach there.
OR
if it is a huge learning curve for you right now, you can get a free azure account and create an Azure Function, as www.myasp.net offer MySQL get the connection credentials.
refer to this :

I want to develop a desktop application (with VB) and connect it to an online database (MySQL), I already had my hosting site and I thought why not create a MySQL database in my domain (which by the way is offered in the pack) and connect my desktop application to this database.
Why an online database? Because I want to develop a mobile application to keep me informed of any changes in my business without moving to my office.
The problem is that my VB6 application cannot connect to my MySQL due to domain restrictions. I wondered how these thousands of apps work with online data? What are their magic solutions? Or did I miss something?
Please any idea? I worked with VB6 and a local database which is no longer productive.
You can create a simple PHP file on your server that will take the data from your VB6 apps and store it in your database. You can also create a simple PHP file that will query your database and return the results in a format that your app can read. This is the typical way that a VB6 app will interact with a server-side database.
I will create a mobile app for Android and iOS. The purpose of the app is to access just a segment of the MySQL database, that part is for customers (the rest of the database is used by employees via my web application).
Is there a way the for FlutterFlow app to access MySQL database instead of FireBase Storage? If not, what are the alternatives?
Though flutterflow has default integration with Firebase firestore database,
below 2 approaches can be used.
API integration approach can be used to use MYSQL database.
Please refer below flow:
You can have backend Server which will host the API.
This backend server will have integration with MYSQL DB
API's will be consumed in flutterflow app
https://docs.flutterflow.io/data-and-backend/api-calls
Custom code approach (Though have not used it before)

I am developing a desktop app and I want to store data in hosted database like MySQL/MongoDB. I know one solution is using webservice to manipulate db. I am wondering is there a way to connect desktop app with hosted db directly.
I am using OpenShift I know I can use port-forward to do this. But it's unpractical to open port forward every time for every PC. So is a way simply like this:
mongoose.connect('mongodb://user:pass#host:port/db');
I tried this but I got 'connect refused' or 'connect not found' errors. OpenShift doesn't allow external access to database directly because security issues, right? Then how could I do it without port-forward?
Also I read some articles about SSH, is it possible to use SSH to access db directly when desktop app is launched?
Thanks for any suggestion.
I don't think OpenShift is going to be a good fit for what you are trying to do, unless you decide to build a service layer between your desktop app and the database. It sounds like you are looking for a Database As A Service. You mentioned both MongoDB and MySQL. MongoLab is a good MongoDB DBaaS option. For other databases like MySQL, PostgreSQL and several others you could look at Amazon RDS.
I'm currently doing a iOS application for school to connect to school mysql database.
It should be able to connect to it through the tools on xamarin studio.
I tried a lot of different coding to connect the database, but was unable to do so.
Is there any tutorial or example code to let me learn on how to do it ?
Thanks for any help!
Do not connect directly to a database from a mobile app. Doing this requires exposing your database server directly to the web, which is a horrible security risk. The better approach is to use a web services layer to broker the interaction between your client and your server.
http://docs.xamarin.com/guides/cross-platform/application_fundamentals/web_services/
While people are right and the best way to connect to a database is to use a web service there are some times you want to connect directly and ways to make the connection more secure (ip restrictions on the mysql server).
Here is a plugin with code examples on how to do it:
https://components.xamarin.com/view/mysql-plugin
Be sure to pay attention to the first forum question on errors and how to resolve. You need to include a reference to system.data, I18N, I18N.West in your project and also make a call to the constructor for I18N somewhere in your code.
new I18N.West.CP1250();
I am working app in which i want that app should connect to Mysql rds on amazon problem is that when we use simpple db they have there api and other things to connect the db and also the domain but how to connect my sql data base tables in iOS app I have search and found that they dynamicdb also so does mysql will be under dynamic db and we will access that use dynamic db api.
You are going to want an intermediary web service via which database interactions are made.
Without this, you would need to make your database have basically no access restrictions AND embed your DB credentials in your app. This would be extremely foolish.
