Windows Print Dialog from Uniface 10

Is there a way to call the Windows Print Dialog box and have it return the selected printer and properties selected?

In our switch to Uniface 10, we are exploring new reporting options.  Previously all printer queue selections went through our report controls, but those controls are no longer available.  I'd prefer to use native windows dialog boxes if at all possible.  All we do is select printers so we can pass them off to our reporting solution for printing.  There's nothing being directly printed in Uniface.

    Here's a local proc I wrote to get a list of printers. I take this list and put it in a drop down box. Hope this might help.

    entry c_get_printer_list
  params
    string p_printer_list : OUT
  endparams
  variables
    string v_ssid_key, v_prt_lst_key
    string v_ssid, v_ssids, v_item
    string v_prt_lst
    string v_printer, v_port, v_driver, v_ext
    string v_printer_list
    string v_redirect1, v_redirect2
    boolean v_continue
  endvariables

  v_ssid_key = "HKEY_CURRENT_USER\\Remote"
  v_prt_lst_key = "HKEY_CURRENT_USER\\Software\\Microsoft\\Windows NT\\CurrentVersion\\PrinterPorts"

  ;first see if this is a remote session, only values above 2 are valid
  v_ssids = $setting("", "%%v_ssid_key%%%\\·*", "REGKEYS")
  if (v_ssids != "")
    ;go through each session (should really only be one
    forlist v_item in v_ssids
      v_ssid = v_item
      if (v_ssid != "") 
        break
      endif
    endfor
  endif

  ;now get list of printers
  v_prt_lst = $setting("", "%%v_prt_lst_key%%%\\·*", "REGVALUES")
  if (v_prt_lst != "")
    ;go through each session (should really only be one    
    forlist v_item in v_prt_lst
      v_printer = $idpart(v_item)

      v_continue = "T"
      ;see if this priter is for this session
      if (v_ssid+0 > 1)      
        v_redirect1 = "(redirected"
        ;if redirect not found, then it's a local printer
        if ($scan(v_printer, v_redirect1) > 0)
          v_redirect2 = "(redirected %%v_ssid%%%)"
          if ($scan(v_printer, v_redirect2) = 0)
            v_continue = "F"
          endif          
        endif
      endif

      if (v_continue)
        v_ext = $setting("", "%%v_prt_lst_key%%%\\%%v_printer%%%", "REGDATA")
        v_ext = $replace(v_ext,1, ",","·;",-1)
        ;example is winspool,TS002,15,45
        getitem v_port, v_ext, 2
        getitem v_driver, v_ext, 1
        v_printer="%%v_printer%%%;%%v_port%%%;%%v_driver%%%;0"
        if (v_printer_list = "")
          v_printer_list = v_printer
        else
          ;add a newline and then the printer
          ;v_printer_list = "%%v_printer_list%%%%%^"
          ;v_printer_list = "%%v_printer_list%%%%%v_printer%%%"
          v_printer_list = "%%v_printer_list%%%·;%%v_printer%%%"
        endif
      endif
    endfor
  endif

  sort/list v_printer_list
  p_printer_list = $replace(v_printer_list,1,"·;","%%^",-1)

  return 0

end ;c_get_printer_list​

    Thanks for that.  My hope is to try to use the standard Windows Print Dialog, as that is what our customers are used to, along with giving us the most possible information.  However, this is excellent information to have and I will keep it in mind as I consider all options.
