Hmmmm... if your question is how to get the Delphi application to accept the commandline parameter then this will do it for you:

Procedure MainFormCreate(Sender:TObject)
var Myfile:string;
begin
  If paramcount>0 then
  begin
   Myfile:=Paramstr[1];
   /// extraction code here using Myfile
  end;
end;



Good luck!!

DrDelphi is right, but he forget to use () instead of [], so it must be:
ParamStr(1), ParamStr(2)...

for i:= 1 to ParaCount do
  ShowMessage(ParamStr(i));

Hi all.
Hi Iwan,

If you want to call external DOS application with parameters from your  Delphi application then:

-----------
uses ...., ShellApi, .....

procedure TForm1.SpeedButton1Click(Sender: TObject);
begin
   ShellExecute(handle,'open','command','/c pkunzip abc.zip abc.dbf',nil,SW_SHOW);
end;
-----------

Sorry if I'm wrong.

Igor.

Is a great detour, but if you try

The recommended component is really easy to use.
