For this, there must be a interface you want to use.

Using dll is same as you was using in VC6. Either by implicit linking or explicit linking.

Hmmm, you need little reading. This series of articles[^] should give you idea.

You need to load dll LoadLibrary and then use of GetProcAddress for return address of function on dll and in the end use of FreeLibrary

Override CRecordView::OnMove . See, if debugging gives you some clue.

My logic itself is wrong. C i'm using certain where condition in my query which means i'll be gettin a fitered result. now the third record shown in the ListBox nowhere means that, it is also the third record in the database. So moving the record pointer taking the LB GetCurSel() as reference is indeed a stupid Confused | :confused:

way of coding.

Sorry to bother u guys up.

The recordset isn't open.
The recordset has no records.

Can you show the code you use to open the recordset ad move to the first record?

I Actually am showing a set of records in a list box and on selection from the ListBox i move to that specific record but i'm not able to go to the first record as shown in the database only so i'm not able to move to the selected records. A certain Offset value is always there which also varies according to the number of records in the recordset.

void CLibManView::OnDblclkBooks() <br />
{<br />
	m_pSet->MoveFirst();<br />
	m_pSet->Move(lb->GetCurSel());<br />
	MessageBox(CLibManView::GetStatus(m_pSet->m_Stat));<br />
}

My whole code is too big to attatch. Frown | :(

What type is m_pSet and what code do you call to open it?

Maybe it's not opened in the proper mode...

m_pSet is of type

<code>CLibManSet* m_pSet;</code>

whereas CLibManSet is of type

<code>class CLibManSet : public CRecordset</code>

its opened as

<code>m_pSet->Open(CRecordset::dynaset, (LPCTSTR)query,CRecordset::none);</code>

Thank you

The source code helps!

Are you sure your "query" is valid and returning a set of records?

If it is working correctly and there are records returned then you should be positioned on
the first record when you "open" the recordset.

m_pSet->Open(CRecordset::dynaset, (LPCTSTR)query, CRecordset::none);
if (m_pSet->IsBOF() && m_pSet->IsEOF())
{
   // recordset is empty (no records)
}
else
{
   // current record is first record in set
}
 
//m_pSet->MoveFirst();
//m_pSet->Move(lb->GetCurSel());

Also if Open() returns 0 then your database isn't connected/open.
No CDBException* being thrown, correct?

dear mark,

the code was extremely useful. As we know if a db contains atleast one record and the record pointer is on the First Record IsBOF() will return 0,

and indeed after using m_pSet->MoveFirst the value of IsBOF() is 0.

But now in MS ACCESS the order of the records are as follows

Ac_No	Name	                                Author	        Type	Value	Date	      Stat
<hr>
1111	Christmas Carol	                        Charles Dickens	2	800	12/12/2006	2
1112	The Adventures of Hucklebery Finn	      Mark Twain	         2	799	12/1/2005	         1
1113	Chip DVD 06/06	                        Chip Magazine	1	100	1/6/2006	         1
1114	Christmas Carol	                        Charles Dickens	2	800	12/11/2006	1
1118	Last Christmas	                        Eagles	         1	299	1/4/2005	         1
1119	The Adventures of Robinson Crusoe	      Daniel Dafoe	         2	799	1/2/2002	         1
<hr>

Even after issuing MoveFirst() the pointer is pointing to 1118.
weird Confused | :confused:

Note: the fields might be a bit mangled plz bear.
