关于DLL调用问题.急,在线等待.

interfaceuses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;type
  TForm1 = class(TForm)
    Button1: TButton;
    Button2: TButton;
    procedure Button1Click(Sender: TObject);
    procedure Button2Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;var
  Form1: TForm1;
  pat:string;implementationfunction tiqifangfa(path:string):boolean;stdcall;external 'E:\dll\Projectwps.dll';{$R *.dfm}procedure TForm1.Button1Click(Sender: TObject);
begin
pat:='E:\内部明电.WPS';
showmessage('已经复制路径。');
end;      procedure TForm1.Button2Click(Sender: TObject);
begin
if tiqifangfa(pat) then showmessage('恭喜你！调用成功。');
end;end.在运行是弹出一个对话框:应用程序正常初始化(0xc000007b)失败.
请问这是怎么回事???
