_bstr_t data type length problem

Did anyone have problem with this type of data type?
It is reported that when the system is heavily loaded
and sqlserver is running like crazy, _bstr_t (returned
from ADO RecordSet) max it to 500 characters.

There is no error - that is even more scary!
just truncated anything beyond 500 chars.

What was the error?
Not able to assess from initial question.

Does it have anything to do with the conn string? Here is what we do:<br />...<br />sprintf(connStr, "Provider=SQLOLEDB;Data Source=%s;Initial Catalog=myDatabase;<br />User Id=%s<img src='/community/emoticons/emotion-4.gif' alt=';P' />assword=%s;", dbServer.c_str(), userId.c_str(), password.c_str());<br />myConnPtr-&gt;Open(_bstr_t(connStr.c_str()), "", "", NULL);<br />...<br /><br />I suspect there is a problem when the column myColumn length &gt; 500,<br />string value = (string)(_bstr_t)RecordSetPtr-&gt;GetCollect(myColumn.c_str()) ;<br />will truncate anything beyound 500 chars.<br /><br /><blockquote id="quote"><font size="1" face="Verdana, Arial, Helvetica" id="quote">quote:<hr height="1" noshade id="quote"><i>Originally posted by satya</i><br /><br />What was the connection string used?<br />How do you control data import/export.<br /><br />_________<br />Satya SKJ<br />Moderator<br />SQL-Server-Performance.Com<br /><br /><hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">
