you can loop through the array to put all the attachment names into the textbox, to display, but you can not then use the textbox text to specify the attachments in the email better to just get them again from the commondialog.filename
like
vb Code:
  1. myarray = split(commondialog.filename, vbnullchar)
  2. for i = 1 to ubound(myarray)
  3.    .attachmentindex = i -1
  4.    .attachmentposition = i -1
  5.    .attachmentpathname = myarray(0) & myarray(i)
  6. next
