QuestionI can save some configuration settings for my app to an ini file for loading when the app starts up. I would like to be able to save those same settings to the registry, optionally loaded from the ini files. Can someone explain to me how to load the ini/text file to the registry using name/value pairs? The ini structure is something like the following:
[XSettings] color=blue color=red color=green [YSettings] range=high range=mid range=low [Zsettings] when=before when=now when=after
Essentialy, I have some listviews which are loaded from
text/ini files that I want to be able to 'backup' to the
registry. Or at least have another option, distinct from ini,
for saving the data. I have just heard about TRegIniFile, and it
sounds like it ought to be able to do both, but I don't
understand how to use it to write to the registry.
Better use Delphi's TRegistryIniFile instead of TRegIniFile, it has more possibilities and it's more compatible with TIniFile.
Also, if you switch from INI files to the registry, you can
rewrite your application with a minimum of coding changes:
only change the code for Create.
IniFile := TIniFile.Create('C:\Software\MyApp');
you code it as:
RegistryIniFile := TRegistryIniFile.Create('Software\MyApp');
Most methods are the same as in TIniFile: ReadString,
ReadInteger, ReadFloat,..., WriteString, WriteInteger,
WriteFloat,..., ReadSection, ReadSections, DeleteKey,
EraseSection, and so on... Don't worry about what happens
behind the scenes: sections are treated as sub-keys in the
registry, and data entries under a section are treated as
ident/data value pairs of that sub-key.
var RIniFile: TRegistryIniFile; begin RIniFile := TRegistryIniFile.Create('Software\MyApp'); RIniFile.WriteString('Images', C:\Pics\Latest\bird.tif', 'Original image as shot from camera');
The key is created automatically if it doesn't exist already, otherwise you overwrite the existing value(s).
