Access comboxes have a very useful ability to search for items as you type in data, e.g. if a combobox has the following items:
Cook Clay Crisp Richardson
and you type in "cr" then "Crisp" will be selected. In order for this to happen you just need to set the combobox's Auto Expand property to True (and sort the combobox's contents in order). However, there is no equivalent property for Access listboxes.
There is, however, a work around. If you create a Class called, say, "ListboxSearch", enter the following code into it and follow the instructions in the comments in its header, you will find that if your listbox has the same items as the combobox above, typing in "cr" will take you to "Crisp" rather than to "Richardson" as would normally happen :
