MFC规则DLL的创建

[yxq123]

手上有一本书,按照书上的要求一步一步做,
就是简单的MFC规则dll应用程序regularDll,当单击"欢迎"按钮时,将弹出"欢迎光临"的对话框.
1.用MFC AppWizard(dll)创建工程,名为regularDll,确定后选择"动态链接库使用共享MFC DLL.
2.在Resource View中的regularDll resources上右击,选择"插入-Dialog-新建",
创建一个对话框,按如下信息添加按钮.
控件 标识符 属性
[欢迎]按钮 IDC_BUTTON1 欢迎
3.按如下信息创建对话框类.
类名:CDllDialog
基类:CDialog
ID值:IDD_DIALOG1
文件:DllDialog.cpp
4.在"欢迎"按钮上双击,创建函数OnHelloButton():
void CDllDialog::OnHelloButton()
{
MessageBox("欢迎光临!");
}
我创建完后运行会出现一个对话框,让用户选择可执行文件名.
不知道怎样解决这个问题???

// TestDll.cpp : Defines the initialization routines for the DLL.
//

#include "stdafx.h"
#include "TestDll.h"
#include "DlgDBConnect.h"
#include "DlgRecordset.h"
#include "DlgTableDesign.h"
#include "DlgTest.h"


#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE

//
// Note!
//
// If this DLL is dynamically linked against the MFC
// DLLs, any functions exported from this DLL which
// call into MFC must have the AFX_MANAGE_STATE macro
// added at the very beginning of the function.
//
// For example:
//
// extern "C" BOOL PASCAL EXPORT ExportedFunction()
// {
// AFX_MANAGE_STATE(AfxGetStaticModuleState());
// // normal function body here
// }
//
// It is very important that this macro appear in each
// function, prior to any calls into MFC. This means that
// it must appear as the first statement within the
// function, even before any object variable declarations
// as their constructors may generate calls into the MFC
// DLL.
//
// Please see MFC Technical Notes 33 and 58 for additional
// details.

DLL是不能单独运行的,又不是EXE,LZ这不晓得吗?
