Error XBROWSE SEEK (while no Index) after change RDD

[Jimmy]

hi,

i got Error when press a Key, after change RDD

Error description: Error BASE/1066 Argument error: conditional

i do open DBF and use

Code: Select all  Expand view  RUN

PROCEDURE SetRddNr( nRDD )
   // nRDD := SP_nRDDlock()
   // DO CASE
   //    CASE nRDD = DB_DBFLOCK_DEFAULT   // 0

   //       SET DBFLOCKSCHEME TO DB_DBFLOCK_HB64
   //    CASE nRDD = DB_DBFLOCK_CLIPPER2  // 6   /* extended Cl*pper locking scheme NTXLOCK2.OBJ */
   //       SET DBFLOCKSCHEME TO DB_DBFLOCK_HB64
   // ENDCASE

   IF hb_OSIS64BIT()
      SP_nRDDlock( nRDD - 1 )
   ELSE
      IF nRDD = 6                                                     // "NTXOBJ2"
         SP_nRDDlock( nRDD )
      ELSE
         SP_nRDDlock( nRDD - 1 )
      ENDIF
   ENDIF
   SET DBFLOCKSCHEME TO SP_nRDDlock()

RETURN

what is going wrong and "why" does "increment SEEK" will be active after change RDD Settings

Version of FWH?
Line numbers are not matching with FWH2212 xbrowse.prg, unless modified.
Are you using Incremental Filter or Seek?
Incremental seek works only for indexed DBF, when an index is selected.

22.07

i do NOT use any Index and that OEM DBF have no *.CDX

i "just" play with "SET DBFLOCKSCHEME" and suddenly "Increment" is active (how to disable Increment ? )

[nageswaragunupudi]

I am trying to understand and learn.

Code: Select all  Expand view  RUN

IF hb_OSIS64BIT()
      SP_nRDDlock( nRDD - 1 )
 

I understand hb_OSIS64BIT() is to check if our Windows OS is 64 bit. If I am right, it always returns .t.
In what way does that affect LockingScheme?
For checking if the Exe is 64-bit (i.e., if the harbour library and RDD is 64-bit), we use FWH function IsExe64(). I do not know if there is a harbour function for this purpose. If one exists, I would like to know.

[Jimmy]

hi,

thx for Answer.

it had to do with this Array aOptions

Code: Select all  Expand view  RUN

   IF hb_OSIS64BIT
      aOptions := { "DEFAULT", "CLIPPER", "COMIX", "VFP", "HB32", "HB64", "NTXOBJ2" }
      nItems := 7
   ELSE
      aOptions := { "DEFAULT", "CLIPPER", "COMIX", "VFP", "HB32", "NTXOBJ2" }
      nItems := 6
   ENDIF

Lock-Mode (not RDD sorry) "HB64", are not available on 32 Bit OS

---

i "think" it was my Error as User can take "every" Lock-Mode
but if use RDD DBFCDX it is wrong to use CLIPPER or NTXOBJ2 Lock-Mode

so i have "disable" RADIONITEM depend on RDD

btw. what RDD use HB32 and HB64

[Antonio Linares]

Dear Jimmy,

> btw. what RDD use HB32 and HB64

They both use the same ones: DBFNTX, DBFCDX, ADS, LOGRDD, ADORDD (not included in the Harbour repo)

They may be more surely...

Eval( ::bSeek, ... )

Looks like you set oBrw:bSeek := nil
We recommend not to. Instead oBrw:bSeek can be { || .f. }
When the dbf is not indexed or not set to any index, the inbuilt bSeek returns .F.

Till FWH2206, Incremental seek was always on by default.

From FWH2212, we can disable incremental seek by setting

Code: Select all  Expand view  RUN

oBrw:lIncrSeek := .f.

YES, i have try to SET bSeek to NIL

my "Problem" was that i have many DBF which work with *.NTX which does not "Autopen" Index

Does not matter.
It is not a good idea to disturb XBrowse's internal defaults.
The default bSeek does not harm you when you are browsing DBFNTX dbfs.
