我查询了CLSID为MSDAINITIALIZE，请教高手解决办法。谢谢@ --------------------编程问答-------------------- 类库没有注册吧。 --------------------编程问答-------------------- 请教zanfeng，注册哪个类库？ --------------------编程问答-------------------- 高手来指教啊 --------------------编程问答-------------------- 看看连接字符串
tring ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|\myDB.mdb;Persist Security Info=True";
通过组件服务调整权限
还有系统所在盘，与写的注册文件bat里调用的dll路径指向的盘是否一致 --------------------编程问答-------------------- 昨天安装了vfp之后才出现的问题。 --------------------编程问答-------------------- 邦顶 ~~~ --------------------编程问答-------------------- 安装VFP之后导致MDAC版本过低
下载最新版试试
