vc++(msdn is for VB).thx

In My program ,I use a ado connection

from
ADOTest.mdb. , the connection is ok ,But
error occur in this command (IDispatch error #3081 )
pRecordset->Open ((IDispatch *) pCommand, vtMissing, adOpenForwardOnly,
adLockReadOnly, adCmdUnknown);

1.if (FAILED (m_pConn->Open (_bstr_t ("Provider=Microsoft.Jet.OLEDB.4.0;Data
Source = ADOTestDB.MDB"),_bstr_t (""), _bstr_t (""), adModeUnknown)))
2.if (FAILED (m_pConn->Open (_bstr_t
("Provider=sqloledb;Initial Catalog=ADOTest;User
ID=sjk;Password="),_bstr_t (""), _bstr_t (""), adModeUnknown)))
3.if (FAILED (m_pConn->Open (_bstr_t ("Provider=MSDASQL; Dsn=ADOTest;User
ID=sjk;Password="),_bstr_t (""), _bstr_t (""), adModeUnknown)))

Hi,

I am not able to reproduce the problem. I think the 3081 error is ADO
error. However, I cannot find the number in ADO docs. Could you debug it
and check the error message?

Refer to the following link to check the error message:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/ado270/htm/
mdmthopenxvc.asp

Hope is helps.

Best Regards,

Bill
