Basic goal is that the application should be universally downloadable,

Is it just me or is there no easy way to open an excel file, and get
the column names that are usually in the 1st row? I would like to be
able to do this for a import tool im writing in vb.net and c#. I need
to be able to list what columns are available in the excel file, so
the user can map these to a ms sql table.

Dim oWorksheet As Excel.Worksheet

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
