I am using Visual Studio 2019 (Version 16.11.5), I want to create one WinForms App project, in which I need two Forms: Form1 and Form2.
When the application runs, at first, only Form1 is shown, Form2 is hide.
On both forms, I add one button. On Form1, when I click on the button, the Form1 will be hidden, and Form2 will be shown; on Form2, when I click on the button, Form2 will be hidden, and Form1 will be shown.
I need this feature for my project, in my project, I need one form to download some files, and I need another form to upload some files when a few files have been downloaded in form1. On each form, there will be a few buttons to trigger some functions to process the files.
