推荐答案

找不到表0。



您没有在数据集中获取任何数据。

检查表格中的记录。如果记录存在，则确保登录用户存在记录。

and i try to login i get the error message
Cannot find table 0.

You're not getting any data in the dataset.
Check the table for records. If records exists then make sure records exists for login user.

Hi Rocky
          Cannot find table 0.is error occurs becouse ur dataset or datatables does'nt have any value at that time.
         I think ur database has some problem ...i think u get value from database in to dataset and then you provide the value to some variable like

 ds is datasetname

 cmd=da.fill(ds);
int a=ds.tables[0].rows[0]["ID"].tostring();

use 

if(ds.tables[0].rows.count !=0)
{
int a=ds.tables[0].rows[0]["ID"].tostring();
}
else
{
//print message
}
you see here in your dataset or datatable no rows found ...check it


it helps you...select as answer..
