在vc中，怎样掉sql server的存储过程？

[fengge_76]

大体步骤，请谈以下。另外还有，接受返回来的记录集

msdn里面有一个sample：

ActiveConnection, CommandText, CommandTimeout, CommandType, Size, and Direction Properties Example (VC++)
[This is preliminary documentation and subject to change.]
This example uses the ActiveConnection, CommandText, CommandTimeout, CommandType, Size, and Direction properties to execute a stored procedure.

这种方法我也会，据说在vc中可以直接掉，不用ado，应该怎么来写呢

[fengge_76]

sorry,hehe,干吗这么生气？
我的没装上源代码，劳驾在贴一次，顺便烁烁怎么使

[strip]

那你害我白忙活，也不讲清楚！！！

你可以使用esqlc, 和流行的在vc中访问db2是一种方式，嵌入式

具体你自己去找吧，安装完sql server 之后在\Program Files\Microsoft SQL Server\80\Tools\DevTools\Samples\esqlc下面，记得安装的时候选定安装源代码

我对你很客气了，下次少涮人，还嘴巴不饶人
