dBase + VB2008

dBase + VB2008

dBase + VB2008

(OP)
I am trying to a Dbase file with a .CDB extension using MS VB2008.
If I change the extension to .DBF everything works fine. I must retain the .CDB extension.
The connection string I am using is:

Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\folder;Extended Properties=dBASE IV;User ID=Admin;Password=;.

I am told the "Microsoft.Jet" engine will only recognise .DBF

Is there any other connection string I could use ?

RE: dBase + VB2008

Have you tried using ADO, creating a ConnectionString and RecordSet?  Although it's a pain and a bit awkward, it does work once you figure it all out.  Here's how it is done in Visual FoxPro (requires installed Microsoft Office2007 OLE ODBC Access Database Engine):

CODE

oConn = CREATEOBJECT("ADODB.Connection")
* set this property:
oConn.Mode
oConn.Open("Driver={Microsoft dBASE Driver (*.dbf)};DriverID=277;Dbq="+myPath)
oRSet = CREATEOBJECT("ADODB.Recordset")
oRSet.Open("SELECT * FROM "+myTable,oConn)
* set these properties:
oRSet.CursorLocation
oRSet.CursorType
oRSet.LockType
Be sure to lookup the various property settings on some tutorial sites such as http://www.w3schools.com/ado/default.asp

ADO drivers do have limits and not all ADO features are coded in every driver, for example, Sort does not workin this driver.

Warning from past experience: If appending a record, any dates in those appended records that are referenced in indexes must have non-empty values or the index *always* gets corrupted and has to be reindexed or recreated from within dBase.  Evidently the driver does not know how to handle null dates when manipulating the index.
