The following code searches all Categories for the contacts that are in each Category, and this includes contacts from the Contact folder, and it's sub-folders, sub-sub folders, and its sub-sub-sub folders. So the Combobox named "ddlCategories" shows the list of all Categories and when I click on one of the Categories, the Combobox named "ddlContacts" shows the list of all contacts assigned to the Category I clicked on, and as to the list of Contacts that show up, each one is link to the specific contact so when I click on the Contact name, it opens up the Contact itself.
But what has happened is that the list of the Categories are not sorted on an alphabetical basis....and the Contacts that show up which are from different folders, are sorted alphabetically as to each folder it comes from, not sorted simply as to all the contacts.
So the question is, is there something to add to the code and where, so that each Combobox sorts what shows up on a full alphabetical basis? Thanks to all.
