Dbmanage | a php class for mysql backup and restore | Continuous Backup library

I am developing an android studio project and would like to be able to access data from a database sitting on the pc which I am programming from. I would like to use a MySQL database as I have worked with them before. I was wondering if it is possible to do it from android studio. If it is possible what would the code be for me to do it? I have looked through other people's questions and answers and all of them yield errors for me. Thanks in advance

I have tried the following and all my ip, port, username and password information is correct but I keep getting the following error: E/Error in connection: com.mysql.jdbc.Driver My code in my connection class after declaring my attributes is as follows

So, in Razor Pages I know how I can use Dependency Injection to inject my DbContext (for example) in the constructor to access it in the whole class by creating a global private readonly variable.

However, let's say I have a DbManager class that makes all the calls to the DB (to avoid making them from every Razor Page in the application), then I have to pass the context to that class, even though I'm using (at least to my knowledge) dependency injection there as well.

Shouldn't it be able to find it without actually passing it to the constructor, and isn't that the whole point of dependency injection, or am I missing something?

What is the best practice here? Just feels wrong to pass the context as a parameter! I suspect I'm doing something wrong... Am I?

I have a Windows Forms application. It has a DataGridView called dgvCalendar. The dgv pulls data from a database, and I've confirmed (as far as I know how to) that there are no issues there.

The form also has has two buttons: btnAll, which displays all of the appointments in the calendar and works as expected; btnMonth which should show only the appointments in the current month.

I've confirmed that there is at least 1 appointment in my current month, but when I click that button, the dgv just goes blank.

If I click the btnAll, it populates again as expected.

I have the fast API application and run schedule task in a background thread as a startup event in fast API. so when I use the SQlAlchemy async session in route scope like: session: AsyncSession=Depends(instance_manger.db_instance.get_db_session) it's ok and runs as correct , but when it's run in the background thread I have the below error. I use python module => SQLAlchemy[asyncio] asyncmy pymysql fastapi

I have created a class, in which I am trying to pass query and return the data in a DataTable, but I am unable to pass a parameter to the SqlCommand.

I have a docker compose application, which works fine in local. I would like to create an image from it and upload it to the docker hub in order to pull it from my azure virtual machine without passing all files. Is this possible? How can I do it?

I tried to upload the image I see from docker desktop and then pull it from the VM but the container does not start up.

Here I attach my .yml file. There is only one service at the moment but in the future there will be multiple microservices, this is why I want to use compose.

I have a code that gets all Item Prices from a database and then makes an API call to update them.

For some reason, loop inside my Button1_click function doesn't work but similar code without the loop on Button2_click will work fine. I cant understand why.

I can see the results of the API calls in the output. It seems like API is called but the price is never updated.

It is my first time dealing with Async functions and Task so I m a newbie at this.
