Delphi - Registry (1)
The Windows registry can be thought of as a global database available to all applications running under Windows. The registry is huge and supports data storage in a variety of formats.
As many people know the registry is open to all sorts of malicious applications whose aim is to bring down firewall and antivirus defences at will. We encourage users to learn and respect the powerful tool that is the registry.
For business applications the registry is an essential part in creating a friendly user interface. By using the registry we can encourage our users to configure certain menu features, application colours, panel positions and more. You should also aim to manage certain application features without the users interaction such as the last position of screens, last login name and the column arrangement in grids. For a professional application you should look to achieve both sets of registry features.
Before we look at the code required to read or write to the registry we will look at the structure of the registry. To open the registry click the START MENU and select RUN then simply type regedit and press return.
The registry is different depending on the version of Windows you are running. However each version contains two common folders:
HKEY_CURRENT_USER
HKEY_LOCAL_MACHINE
