Why Selenium Webdriver freezes the Windows Form Appliaction?

Question

Anyone out there can help me with this problem. I have searched it even on google but find nothing. I have made a Windows Form Application for scraping some data. Problem is this when i click on the button the script starts in a headless mode and i am using Chrome Web-driver. It then freezes the application in a sense it did not let us use the other buttons on the application while running the script.

There's any solution to it or any other framework or thing which i can do?

It has to do with the fact that your application is single-threaded. Means that all the code it executes, is run on a single thread. So you don't have a way to do some work while your user is changing the UI state and viceversa.

A good solution is to run the "selenium script" (or the routine that fires it) on a thread that is not the one your application is using for the UI.

You can achieve this in some ways:

Using the Task Class
Using the Thread Class
Using a BackGroundWorker Class that come within' Windows Forms.

Always remember that your default execution thread (in Windows Forms) is the one that keeps the UI and your application alive.

Put the actual work in a background task and not into the click handler of the button.

Running a task in the background why UI is interactable: https://stackoverflow.com/questions/21419229/c-sharp-threading-async-running-a-task-in-the-background-while-ui-is-interactab – D.R. Mar 02 '19 at 12:02
