1. 1) Name four properties of an OpenFileDialog that we often set prior to using ShowDialog() to
open that screen
i) ValidateNames : Gets or sets a value indicating whether the dialog box accepts only valid
Win32 file names.(Inherited fromFileDialog.)
ii) RestoreDirectory : Gets or sets a value indicating whether the dialog box restores the directory
to the previously selected directory before closing
iii) CheckFileExists : Gets or sets a value indicating whether the dialog box displays a warning if
the user specifies a file name that does not exist.
iv) ShowReadOnly : Gets or sets a value indicating whether the dialog box contains a read-only
check box.
2) XML stands for ' Extensible Markup Language '.
3) HTML Stands for ' HyperText Markup Language '.
4) what would you set the filter to for an OpenFileDialog if you wanted the user to only be able
to select the text file
