If Not (rs.BOF And rs.
为什么他的值是0呢?应该是1啊!

If Not (rs.BOF And rs.为什么他的值是0呢?应该是1啊!
如果数据集数是0时,值当然是0啦,rs.bof 和rs.eof 他们分别是数据集的头和尾的位置,因为数据集数是0时,rs.bof和rs.eof都是指向同一个地址,所以 (rs.BOF And rs.EOF)的值是1,not (rs.BOF And rs.EOF)值就变0了,

If Not (rs.BOF And rs.为什么他的值是0呢?应该是1啊! 谁能详细解释asp中if not rs.eof and not rs.bof then怎么理解? if rs.eof or rs.bof then 和if rs.eof and rs.bof 它们一样不?
