Delphi help

When I try to run this code in delphi, I get an eAccessViolation error on the AddFromFile line. Any hints as to what I'm leaving out or doing wrong?

uses
   ..., DMCSCRIPTINGLib_TLB;

------

procedure TForm1.Button1Click(Sender: TObject);
var
    Converter: IConverterDisp;
begin

    Converter.AddFromFile(WideString('d:\\music\\file.m4a'));        // Add a File
    Converter.GoConversion(WideString('Mp3 (Lame)'),0,0,0,0);     // Convert
end;

Re: Delphi help

I am guessing (as don't use Delphi), that the Widestring is not correct, a BStr is needed (which is slightly different to a normal unicode string).

Re: Delphi help

It specifically says in the help that WideString is compatible with the COM BSTR type. There is no BStr function. I think the problem is that the Converter is not initialized properly...

some kind of Converter.create() or something?

Re: Delphi help

all I'm looking for is a quick executable that will take a command line argument and convert it to MP3 lame. It's basically three or four lines of code. If someone could compile it for me, that'd be great.

Re: Delphi help

you are probably right about that converter.create....

try like this (looselly):

converter := IConverterDisp.create();

or something like that any way...
in my case (for the player) I had :

amp:= tamp.create(form1);

then I was able to access amp.volume (for instance)
