Can I save program variables with LMDStorPropertiesStorage?

Ian BranchIan Branch
in LMD-Tools
Hi Team,
I would like to save a program variable automatically and re-load automatically a.k.a LMDStorPropertiesStorage.
Can I do it with the above component?  If so, please advise how.
If not.  Can you suggest an alternative mechanism?

Regards & TIA,
Ian

    The answer is - Yes.
    I used the CustomProperties Property.  Have to read/write them manually in the program but saving/loading happens as with component properties.

    Hi,
    I don't find a way to do this.
    There is a little example?

    Thanks!

    Assuming you populated CustomProperties collection at design-time with the list of your desired custom properties, specifying the Name and possibly default value for each, you can access it in code like this:

    procedure TForm1.MyButtonClick(Sender: TObject);
    var
      pp: TLMDStorCustomProperty;
    begin
      pp := LMDStorPropertiesStorage1.CustomProperties.FindItem('MyProp');
      if pp <> nil then
        pp.Value := 7; // Write or read custom property value.
    end;

    You can do this while your application running, e.g. after the state has been read at startup and before it will be saves on shutdown.
