@#这个函数本打算用来实现点击表头排序功能,可是后来总是随机性无故出错,所以就没在现用了,哪们高手可以看看
@#DataGrid功能:
@# 将数据以表格形式显出来,
@# 根据需要可能确定显示的字段,
@# 页号,每页显示的记录数
@# 复选框绑定的字段
@# 修改数据时所连接到的设定的网页,传递的参数名是Idfield
@#调用实例 call DataGrid("SELECT * FROM mater_bcode","Driver={
SQL Server};uid=sa;pwd=passed;database=cthpdb;server=scb-web",10,20,2,50,0,"http://www.clkhome/mater_code1/tools/aaa.asp","Null")
@#参数说明
@#sqlstr: 将要查询的sql语句
@#connstr:
数据库连接字符串
@#PageSize: 数据集每页的记录数,PageSize="MAX"时不分页
@#PageNum: 数据集中将要显示的页号
@#beginField:在记录集中开始显示的字段位置
@#EndField: 在记录集中结束显示的字段位置
@#IDField: 用于给复选框的value赋值的字段在记录集中的位置,可以用于提交到其它页,其它页做处理的依据
@# 如果IDField<0 or IDField> rs.fields.count或不是数字 则不显示复选框
@#HttpStr 修改记录时连接到的网页,传递的是IDField的值,如果 httpstr="0"则不显示修改连接
@#PageInfo 确定是否显示"第1页,共1页"的提示,PageInfo="Null"时不显示
@#返回值, 返回的是记录集的当前页号
