谁能帮我调试这个程序！(50分)

我们首先要建立一个ActiveX Library。将其保存为MailIEBand.Dpr；然后建立一个COM Object，将其保存为BandUnit.pas；然后建立一个Form，这个窗口将作为子窗口显示在IE工具栏中，将窗口的BorderStyle属性改为bsNone，添加一个TButton组件和一个TComboBox组件，将TButton的Caption属性改为获取全部，然后将窗口文件其保存为IEForm.pas。
在BandUnit中，需要建立一个实现上面提到的接口的TComObject对象。如下：
TGetMailBand = class(TComObject, IDeskBand, IObjectWithSite, IPersistStreamInit)

另外由于需要在COM服务器注册时添加一些注册表信息，所以还需要建立一个继承自TComObjectFactory类的对象，在对象的UpdateRegistry事件中编写代码添加附加的注册表信息。
下面的程序清单1-6到1-8是实现COM服务器的全部程序代码：

程序清单1-6 MailIEBand.dpr
library MailIEBand;

uses
ComServ,
BandUnit in 'BandUnit.pas',
IEForm in 'IEForm.pas' {Form1},
MailIEBand_TLB in 'MailIEBand_TLB.pas';

exports
DllGetClassObject,
DllCanUnloadNow,
DllRegisterServer,
DllUnregisterServer;

{$R *.TLB}

{$R *.RES}

begin
end.

编译工程，关闭所有的IE窗口，然后点击Delphi菜单的Run | Register ActiveX Server 项注册服务器。然后打开IE，点击菜单 察看 | 工具栏 项，可以看到子菜单中多了一个GetMailAddress项，选中改项，工具栏就出现在IE工具栏中

我弄不好，技术太差了，但是急需这个代码，请高手把调试好的代码文件发送到seemestudio@163.com,谢谢，给分！
