问题描述

我有一个用c ++编写的32位应用程序，我希望将其定位到64位。该应用程序使用DAO连接到我的访问数据库。我该怎么办？



我的尝试：



我当我尝试通过更改设置Win64平台不支持DAO数据库类时出现以下错误。

I have a 32 bit application written in c++ which I wanted to target to 64 bit. The application uses DAO for to connect to my access database. How do I proceed ?

What I have tried:

I get the following error when I tried to target by changing the settings "DAO Database classes are not supported for Win64 platforms".

推荐答案

此消息很明确：您无法使用此版本适用于Windows 64的DAO类。



尝试获取这些类的较新版本以编译为64位。例如，使用Visual Studio 2015。

This message is clear: you cant use this version of DAO classes for Windows 64.

Try to get a newer version of these classes to compile for 64 bit. For instance with Visual Studio 2015.

Google查找信息的错误。您的问题不包含错误编号，但这可能有所帮助。
