View 2 RepliesBasically what i need is for something to look at the items in a list box then compare it to the contents that is in the database. The issue is that the listbox can have more than one of the same item. For instance, LstBox_Order.items(0) could be the same at any position in the listbox. This code works, but it is slow if there is like 10 or more items added.

View 12 RepliesI have a function that I use quite a bit that I wrote more than 2 years ago. It works fine but recently I saw how it can use up a good deal of time under certain condition. Here's some code that uses the function SelectValue The function works so that if you had N which you plug into the function rising continuously while SelectLimit was set to 255 then SelectValue would match N until N reached 256. SelectValue would start to descend to 0 until it reached 0 and then it would again ascend to 255 and the process would repeat. So SelectValue(255, 255) would return 255 and SelectValue(256, 255) would return 254. SelectValue(257, 255) would return 253.
