问题 First I want to say that I'm a beginner in Access, and I will appreciate every bit of help I can get. I have created a form showing records from one of my tables with three subforms.

In WinForms, I was able to use: MainWindow main = (MainWindow)Application.OpenForms["MainWindow"]; To be able to access the the form. Now in WPF it does not exist.
