numero = 25286
interpreted = N
texte = Random includes the possibility of repeated numbers, by definition. However, if you do not want to repeat, add a field to the image database called SHOWN (or whatever) and do your random search on all records where SHOWN not Y; once you have selected an image, update that record with SHOWN=Y. The last thing you need is a test for [NumFound]=0, in which case you reset the whole table and do another random search.HTHJohn Peacock ____________________Reply Separator____________________ Subject: Generating a random image, but avoiding repeated images. Author: (WebCatalog Talk) Date: 12/8/99 1:55 PMWe have a database of several hundred images from which I would like to pull a random image. This is pretty easily accomplished using the Search feature and its random function.My question is this: How can I make sure that each image gets displayed at least once, and that there aren't repeating images?My first solution is to implement a secondary database which records the number of the image, say 3 of 200, and if 3 of 200 was previously displayed, it would automatically do another random search until it found an unused number graphic.Does this make sense? Is there a shortcut in webcatalog so I can have the search be sure to generate non-repeating random results?Thanks for any assistance.Christopher Feyrer System Administrator FoodSpot.com chris@foodspot.com ------------------- PGP 6.x key available.------------------------------------------------------------- Brought to you by CommuniGate Pro - The Buzz Word Compliant Messaging Server.
