Where I can get the detailed description

[sanford101]

I got this error message while I was trying to delete a row from table with the datagrid control and ado control. the error message is

A Given HRow refered to a hard or soft deleted row. -2147217885.(80040e23)

I had two questions with this message. The important one; where can I get the detailed account of this kind of error message where
I get see what is the reason behind it.
is there a special word I can use to search the MSDN Lib.?

The second question is How can I sovle the problem. I try all kinds of updatemode and
cursor type. there is only ado control and datagrid control and one line code
adodc1.recordset.delete.

Thanks for reading.
