Re: Delphi5 and GetExternalData ...

[Software FX]

Passing pointer to COM Objects in Delphi is quite awkward. Here is the code 

that will do what you need: 

var 

  rFileName : TCfxDataFile; 

begin 

  try 

    rFileName := TCfxDataFile.Create(self); 

    rFileName.FileName := 'd:\temp\data.txt'; 

    ChartFx1.GetExternalData(rFileName.DefaultInterface); 

  finally 

    ChartFX1.Refresh; 

  end; 

end; 

Notice the Explicit call to DefaultInterface as Delphi will not know how to 

directly convert a TCfxDataFile to an OLEVariant.
