<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D;mso-fareast-language:JA">Some disadvantages with the lstToListBox procedure, not efficient as it keeps clearing and re-adding old stuff on call which is redundant and refreshes can be noticeable
when lists are sufficiently large. Advantage: well could easily replace the procedure for another display type and not need to worry about discrepancies in the list and listbox. Also can reuse the procedure in other buttons like delete etc. Hope that helped.<o:p></o:p></span></p>
