CallDll

Here is the delphi code:

library FormDLL;

uses
Unit1 in 'Unit1.pas' {Form1};

exports
getfile;

end.


unit Unit1;

interface

uses
Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
StdCtrls;

type
TForm1 = class(TForm)
OpenDialog1: TOpenDialog;
Button1: TButton;
procedure Button1Click(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;

function getfile (fis: Pchar) : pchar; stdcall;

var
Form1: TForm1;

implementation

{$R *.DFM}

procedure TForm1.Button1Click(Sender: TObject);
begin
opendialog1.Execute;
end;

function getfile (fis: Pchar) : pchar; stdcall
var
Form1 : TForm1;
begin
Form1 := Tform1.Create (application);
form1.OpenDialog1.Execute;
end;

end.
