You are only showing the code you use to open the file.
What have you tried regarding the progress bar?

To do a progress bar in WPF, add a ProgressBar element in your UI (XAML):

<ProgressBar x:Name="progress" Minimum="0" Maximum="100" />

Then, update its value in code:

progress.Value = 50;

MSDN Documentation and tutorial.

The difficulty here will be getting the progress information from your Read...File() methods. You may have to refactor your MSAccessOperations class to fire events indicating the progress. But this is unrelated to WPF.

agree with Xavier, you need to keep updating the progress bar value with reference to your backend code.
