LoadFromRegistry method

Applies to

acStringListContainer component.

Declaration

procedure LoadToRegistry(Reg: TRegistry); overload;

procedure LoadToRegistry(const KeyName: String; const RootKey: hKey = HKEY_CURRENT_USER); overload;

Description

The LoadToRegistry method loads the strings to the from the registry.

There is 2 overloaded methods of calling the LoadFromRegisty:

1. The registry key must be previously opened and handle to TRegistry object must be passed with Reg parameter (see first example below);

2. You must pass the KeyName and the RootKey (HKEY_CURRENT_USER or HKEY_LOCAL_MACHINE) as parameters (see second example below).

Screenshot from RegEdit (demonstrates how the values should be stored in registry to load them. They can be previously stored in this form with StoreToRegistry method)

Example 1 (if the TRegistry object already prepared before saving of the strings)

uses Registry;

procedure TForm1.Button1Click(Sender: TObject);

var

MyKey: String;

Reg: TRegistry;

begin

MyKey := 'SOFTWARE\My Company Name\My Program Name\StringList';

Reg := TRegistry.Create;

with Reg do

try

RootKey := HKEY_CURRENT_USER;

if OpenKey(MyKey, False) then

acStringListContainer1.LoadToRegistry(Reg);

finally

Free;

end;

end;

Example 2 (if we want to pass the KeyName and RootKey as parameters without preparing of the TRegistry object)

procedure TForm1.Button1Click(Sender: TObject);

begin

acStringListContainer1.LoadToRegistry('SOFTWARE\My Company Name\My Program Name\StringList');

end;
