为什么运行时总是出现“This application has requested the Runtime to terminate it in an usual way.Please contact the application'

[cnsgp]

为什么运行时总是出现“This application has requested the Runtime to terminate it in an usual way.Please contact the application's support team for more information.”
我是VC菜鸟，在学习《Visual C++6.0应用编程150例》时，其中的部分数据库编程例子总是无法正常工作。其特征是：
1.都是控制台程序
2.编译运行时，都出现“This application has requested the Runtime to terminate it in an usual way.Please contact the application's support team for more information.”提示，调试时，出现“Unhandled Exception in Kernel32.dll...”，然后程序非正常退出。这样的程序例子有１０个左右。恳请高手指点！

源码１：修改数据库密码

{
int nRetCode = 0;

// initialize MFC and print and error on failure
if (!AfxWinInit(::GetModuleHandle(NULL), NULL, ::GetCommandLine(), 0))
{
// TODO: change error code to suit your needs
cerr << _T("Fatal Error: MFC initialization failed") << endl;
nRetCode = 1;
}
else
{
// TODO: code your application's behavior here.
CDaoDatabase m_MyDatabase;
m_MyDatabase.Open("c:\\BIBLIO.MDB");
printf("Tables' Count: %d\n",m_MyDatabase.GetTableDefCount());
//LPCTSTR str_SQL="Create Table NewTable(Field1 Text(10),Field2 Short)";
CString str_SQL="Create Table NewTable(Field1 Text(10),Field2 Short)";
m_MyDatabase.Execute(str_SQL);
//LPCTSTR str_SQL="Create Table NewTable(Field1 Text(10),Field2 Short)";

m_MyDatabase.Close();
m_MyDatabase.Open("c:\\BIBLIO.MDB");
printf("Tables' Count: %d\n",m_MyDatabase.GetTableDefCount());
m_MyDatabase.Close();
}

return nRetCode;
}

using namespace std; 你看去掉怎么样，我觉得好象有点别扭，你上面用了 .h 下面就不要在用std了

[cnsgp]

谢谢littleeagle007(007)，我试了，去掉using namespace std;后连编译都不能通过：
Compiling...

可能是DAO连接DB还需要什么DLL吧

就像ADO一样，需要链接msado15.dll

你找找资料看，我也没用过DAO访问DB，

ODBC数据源没配好吧？

貌似连接字字符串不对的时候也会出现这种问题。
今天我还遇到。
