控制台程序里面使用数据库的问题

[gooyan]

控制台程序选择了支持MFC
使用带MFC的consol程序
在stdafx.h中引入：
#import "C:\Program Files\Common Files\System\ado\msado15.dll" no_namespace rename("EOF","adoEOF")
然后再tmain中使用
if (!AfxSocketInit())
{
AfxMessageBox(IDP_SOCKETS_INIT_FAILED);
return FALSE;
}

结果
F:\try\regedit\ReadPolicy_con\ReadPolicy_con.cpp(22) : error C2065: 'AfxSocketInit' : undeclared identifier

AfxSocketInit
BOOL AfxSocketInit( WSADATA* lpwsaData = NULL );

Return Value

Nonzero if the function is successful; otherwise 0.

Parameters

lpwsaData

A pointer to a WSADATA structure. If lpwsaData is not equal to NULL, then the address of the WSADATA structure is filled by the call to ::WSAStartup. This function also ensures that ::WSACleanup is called for you before the application terminates.

Remarks

Call this function in your CWinApp::InitInstance override to initialize Windows Sockets.

See Also CWinApp::InitInstance

这个函数与数据库操作无关

使用ado要：
CoInitialize(0); //初始化COM库

要使用AfxSocketInit（）必须加入
#include "afxsock.h"

手误，呵呵。应该是AfxOleInit()

不过请看看是AfxOleInit的问题
