    I have attached file PrintTextVC.zip to this post.

    It is a Visual COBOL version of the demo program that you referenced.

    I am also including the source code here for quick reference:


          $set ilusing"System.Windows.Forms"
          $set ilusing"System.IO"
          $set ilusing"System.Drawing.Printing"
           class-id PrintTextVC.Form1 is partial
                     inherits type System.Windows.Forms.Form.
           
           working-storage section.
           01 verdana10Font type Font.
           01 reader        type StreamReader.

           method-id NEW.

              set fdlg::InitialDirectory to "C:\\ "
              set fdlg::Filter to "Text files|*.txt|All files (*.*)|*.*"
              set fdlg::FilterIndex to 2
              set fdlg::RestoreDirectory to true

              if (fdlg::ShowDialog = type DialogResult::OK)
                 set textBox1::Text to fdlg::FileName
              end-if
