本文介绍了Windows 7不能正确运行xb的vb应用程序的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我创建了一个vb.net应用程序，该应用程序可以在WindowsXP中很好地运行.
我只是试图将其安装到Windows7中，然后在保存方法中发生了错误.
除此之外，其他方法也可以.
是什么原因造成的?代码还是Windows?
如果有人知道就告诉我.
该方法的代码如下(我的编码可能不干净^^)
I had created a vb.net application which is able to run well in windowsXP.
I''d just tried to install it into windows7 and an error occured in a saving method.
Other method is ok except for this.
What should be the cause of it? codes or windows?
If anyone knows just tell me.
The code of this method is below (My coding may not clean ^^)

推荐答案
最有可能是
与权限相关的问题.
在win 7中Access数据库变为写入
保护.并且它限制用户在
中添加或修改 数据库.
您应该授予用户所有权限.
如果我的假设是正确的，请访问链接[ ^ ]
请按照以下步骤操作，然后尝试保存
Most Probably It must be the
Permission related issue.
In win 7 Access database becomes write
proteced .And it restricts user to add or modify into
the database.
You should give the user all Permissions.
If my Assumtions are true.Visit the link [^]
Follow the Steps and then try to Save
基于错误，权限不是问题.您的问题似乎是您正在尝试使用未返回主键或试图在错误位置使用查询的查询.例如，代码正在尝试执行Update命令，并且您为其SQL提供了SELECT查询.
Based on the error, permissions are not the problem. Your problem seems to be that you are trying to use a query that either didn''t return a primary key or are trying to use a query in the wrong place. For example, the code is trying to execute an Update command and you supplied a SELECT query for it''s SQL.
