I have a Windows Forms app I’ve been developing and all of a sudden two errors show up in my Errors List tab that are strange.

I have a WinForms app that needs to have a custom titlebar, so I removed the native titlebar via FormBorderStyle = FormBorderStyle.None

I am programming a desktop software for my workouts and I have a main form, in which I have a page for “short-term planning” (pg_KurzfristigeTrainingplanung). From that page I call another form (frm_KurzfristigeTrainingsplanung), where I enter the dates and the workouts I want to train those days. With a button I want to “feed back” those entries to that very same page “short-term planning” (pg_KurzfristigeTrainingplanung) from which I called the form for the planning.
The values I entered in the form shall then be entered into the page and also “stay” there until I change them again (as well after closing the entire program).

I am using circular progress bar NuGet for my application. My application reads a very big excel file, does some processing in the rows, and then does some other work. I am not sure how to set the maximum for my progress bar. At the moment, I have set it to the number of rows the application will process, but the issue with this approach is that the progress bar will show till the tool is processing the excel file and then it will close , though there are other processes that are being done after that also.
