Strange behavior of ACTION clause

[Enrico Maria Giordano]

Try the following sample (you will need of an MDB file). Now remove the comment of the ACTION clause and you will notice that the LDB file is not deleted anymore. Why?

Code: Select all

#include "Fivewin.ch"


#define adOpenForwardOnly 0
#define adOpenKeyset      1
#define adOpenDynamic     2
#define adOpenStatic      3

#define adLockReadOnly        1
#define adLockPessimistic     2
#define adLockOptimistic      3
#define adLockBatchOptimistic 4

#define adUseNone   1
#define adUseServer 2
#define adUseClient 3


FUNCTION MAIN()

    LOCAL oRs := CREATEOBJECT( "ADODB.Recordset" )

    oRs:Open( "SELECT * FROM Clienti", "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=clienti.mdb", adOpenKeyset, adLockOptimistic )

    TEST( oRs )

    oRs:Close()

    oRs = NIL

    RETURN NIL


STATIC FUNCTION TEST( oRs )

    LOCAL oDlg

    DEFINE DIALOG oDlg

    @ 1, 1 BUTTON "";
//           ACTION oRs

    ACTIVATE DIALOG oDlg;
             CENTER

    RETURN NIL

Enrico,

> the LDB file is not deleted

Whats the LDB file ?

[Enrico Maria Giordano]

It is a file that Jet engine uses to handle multiuser locking. It should be automatically deleted when the database is closed.
