you could provide one text box first, and use an IF statement and if if matches, make visible, on the same form, a second text box and test those for equality.


VB Code:
  1. 'This would be in a button_click event

  2.  
  3. frmDialog.showdialog

  4.  
  5. 'this would be in another _click event on frmDialog

  6.  
  7. dim OldPass as string = textbox1.text

  8.  
  9. if pass <> [whats on the DB] then

  10.  
  11. 'provide an error here

  12.  
  13. else

  14.  

  15. textbox2.visible = true

  16. buttonChangePass.visible = true

  17. end if

  18.  
  19.  
  20. 'This would be a _click event for a buttonChangePass

  21.  
  22. if textbox1.text <> textbox2.text

  23.  
  24. 'provide an error here

  25.  
  26. else

  27.  
  28. 'Make the changes on the database according to text box1 or 2
