关于asp里if then和if not then的问题一段代码photo=rs(photo)if photo = then response.write(无照片)elseresponse.write( 谁能详细解释asp中if not rs.eof and not rs.bof then怎么理解? IF Not Rs.Bof [asp]asp里的.IF Not Rs.Bof Set Rs = Conn.Execute(Select * From Nt_Imgbook)IF Not Rs.Bof ThentitleIDArr = 全部商品1ElsetitleIDArr = 全部商品2End IFresponse.write titleIDArr IF-THEN-END IF和IF-THEN-ELSE-END IF这里的END IF前后意思不一样吧? If you are not serious, then do not bother.是什么意思 在asp里的这句话什么意思 if (c < 48 || c > 57) IF ANY,IF SO,IF NOT,IF if never,if any,if not,if If do not believe me,then don't ask if not if-then-else是什么意思 If text1.text then... vb里corp是什么 意思,如：If corp Then if.then if.then if.then else end if 以上这种语句是不对的吗? if.then不能循环? If you love me assure you that if you do not love me,then do not believe me If you do not marry you after years,if I married,then we can not be together? Pascal里If语句Then后面的语句加Begin和End和不加有什么区别吗? if...not和unless怎么转换
