1- AccessibleName 2- AccessibleRole

What are these properties and what's their usages in an win form application? I have already take a look at MSDN but unfortunately I couldn't understand their descriptions?

Answer 1

Those are special attributes that can be used by screen readers or text-to-speech programs to make your program accessible to people with disabilities or who use assistive technology.

AccessibleName can be used to tell the user the element the cursor is sitting in. E.g. the assistive technology program can't determin which label around the text box belongs to it, but it's able to read that attribute (i.e. "what's the meaning of this box?"). A more detailed description can be added to AccessibleDescription.

In a similar way AccessibleRole describes the user (or tells the tool) what kind of control this is. This isn't as important for the standard controls, but imagine some custom button or hyperlink control: With this attribute it's able to tell "Hey, I'm clickable and I'm a button/link!".
