ReadBooleanDef(ValueName: String; DefaultValue: Boolean): Boolean;
ValueName - name of the parameter, which value must be obtained.
DefaultValue - value that is used if parameter does not exist.
The ReadBooleanDef method reads logical value from the DWORD parameter in the registry. If the parameter with the ValueName name does not exist, the method returns DefaultValue.
Sub Main;
Var
RegKey, SubKey: IRegistryKey;
b: Boolean;
Begin
RegKey := RegistryClass.CurrentUser;
SubKey := RegKey.OpenSubKey("Software\MyProject\Params", False);
b := SubKey.ReadBooleanDef("Param1", True);
End Sub Main;
After executing the example logical value is read from the parameter with the Param1 name located in the registry subkey HKEY_CURRENT_USER\Software\MyProject\Params into the "b" variable. If the parameter does not exist, the "b" variable contains the True value.
