    OleVariant Problem with Delphi 6

    Hello

    I'm trying to use the Item property within Delphi 6 such as: -

    FMap.Shapes.Item[1].Name := 'my name';

    but it keeps giving me the erorr message: -

    Types of actual and formal var parameters must be identical

    I must admit, I'm lost around variants and Olevariants, so I don't know where to start looking for a problem.

    Any help would be appreciated.

    Thanks in advance.

    Les

    Top204:

    You first need to define a variable to store the item number. In your routine, create a variable defined as an olevariant. For example:


    procedure TFMain.AssignName;
    var ilevariant;
    begin
    FMap.Shapes.Item[i].Name := 'my name';
    end;

    That should do it.
