Description
In today's times Lookup forms are ideal for applications that need a compact and tidy way to present the user with a search & selection type screen. A simple example is the Windows 'Open File' dialog box which pops up in front of the current screen and remains 'on top' until a file is selected or the dialog is closed. In Delphi you too have the option to use the standard Windows dialogs such as PageSetup dialog, OpenFile dialog etc.. In this article we create our own type of dialog which we refer to as a 'Lookup form'. A common situation for a Lookup is if you want your users to perform a database search to find a specific Customer and then return the selected customer details to the calling form. This is just an example and there are many, many ways you can use Lookup forms to create modern applications using Delphi.
