Running an application asynchronously

[devans123456]

Hello, I currently have an application that when running, has to load a lot of data and it takes too much time. The data is coming from a SQL database. I am not very familiar with async and was wondering if there is a way to run the application asynchronously through the Init() method? Thank you.

That doesn't make any sense. Are you asking if you can load the data on a background thread while your application finishes starting up??

Sorry. I am not very good at trying to explain. But basically my application takes a very long time to load and was looking into trying to load it asynchronously through the Init() method because this method calls the different connection strings. Or could even have it load the data on a background thread like you mentioned, but I am unsure of how this is accomplished.

Currently the project is taking a tremendous amount of time to load. And we are required to have a loading image showing while the application is accessing the data from the database. The code below is where the asynchronous code should be placed so I am being told by my fellow co-workers. Public Sub Init(ByVal solution As Solution) LoadingDataSymbol.Visible = True _presenter = New TranslationPresenter(Me) _presenter.getProjects(solution) End Sub This code sets the image visible and gets the data from using getProjects(solution). I am required to make these two items async and turn the image visible before and invisible after. Any suggestions???

Look into the BackgroundWorker component in the ToolBox.

How would that be incorporated in the code that I had just posted?

You drop the component on the form, then in your Init code for the form, setup the event handlers, then send it on it's way. Read this...[^]
