如何通过sdeworkspacefactory新建featureclass

<P>怎么样用ae实现在sde数据库中新建一个featureclass呢？或者说新建一个shapefile然后把它用程序导入到sde数据库中？下面是我的代码，但是有错误，请大家帮忙看一下</P>

数据库版本注册了吗?

<P>谢谢老大的回复！！！</P>
<P>恕我愚钝，我没怎么明白您的意思！</P>

哦，注册了。在数据库的SDE.versions表中已经含有DEFAULT行，它的state_id为0

<P>gis老大，我的代码也和上面的一样，我的数据库也注册了，但是提示：</P>
<P>HRESULT ERROR: 0x8004021 </P>
