来源：百度文库 编辑：杭州交通信息网 时间：2024/04/28 05:23:00
我写了一个简单的程序,里面要用到DLL静态调用,但不知道为什么不对,各位高手帮看看吧.我是初学者,大家不要取笑啊
unit Unit1;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls;
type
TForm1 = class(TForm)
Button1: TButton;
Label1: TLabel;
OpenDialog1: TOpenDialog;
procedure Button1Click(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;
var
Form1: TForm1;
filename:string;
implementation
{$R *.dfm}
function GetTime(filename:string):integer;
external 'E:\ReadTsFileInfo.dll';
procedure TForm1.Button1Click(Sender: TObject);
begin
if OpenDialog1.Execute then
begin
filename:=OpenDialog1.FileName;
Label1.Caption :=inttostr(GetTime(filename));
end;
end;
end.
unit Unit1;

begin
if OpenDialog1.Execute then
begin
filename:=OpenDialog1.FileName;
Label1.Caption :=inttostr(GetTime(filename));
end;
end;
end.
枚举类型有错，条件分支表达式不通。
inttostr(GetTime(filename)); 这是什么东西你知道不
