APPEND FROM ... SDF

[E. Bartzokas]

I don't really know if this an XHB error or FWH error.

It worked before Feb 2006 (XHB and FWH), but now it crashes

Code: Select all  Expand view

   Error description: Error DBFCDX/1023  Exclusive required

   Called from:  => __DBPACK(0)
   Called from: dbsdf.prg => __DBSDF(241)
   Called from: IMP_CLK.PRG => IMPORT_HRS(343)

   Line 343 contained this below, but never had problems before 10/mar/2006

   append from (xClPath+"_MAST.TXT") SDF   


My search for DBSDF.PRG in FWH\SOURCE failed of course ...

The original code was as this:

Code: Select all  Expand view

   Create (xClPath+"_MIMP.DBF") FROM (xClPath+"_MAST.STR")
   newinfile := Select()
   SELECT (newinfile)
   append from (xClPath+"_MAST.TXT") SDF
   (newinfile)->(DBCLOSEAREA())


My solution was to add this line:

Code: Select all  Expand view

   Create (xClPath+"_MIMP.DBF") FROM (xClPath+"_MAST.STR")
   newinfile := Select()
   SELECT (newinfile)
   USE (xClPath+"_MIMP.DBF") alias QQQQ EXCLUSIVE  //  added
   append from (xClPath+"_MAST.TXT") SDF
   (newinfile)->(DBCLOSEAREA())


Any advise ?

The following sample works fine. Can you modify it to reproduce the problem?

Code: Select all  Expand view

FUNCTION MAIN()

    USE TEST SHARED

    COPY TO TMPTEST FOR .F.

    USE TMPTEST SHARED

    APPEND FROM TEST

    GO TOP

    BROWSE()

    CLOSE

    FERASE( "TMPTEST.DBF" )

    RETURN NIL

Sorry for the long example.
This example you can save in \FWH\SAMPLES and run it.
I use XHB Professional ver. 4.01 Jan 24 2006 09:15:21

APPEND FROM ... DATABASE works fine.
APPEND FROM ... SDF does not work (see the error below)

Thanks for the interest

Confirmed. Already reported in the xHarbour developer's mailing-list.

Thank you.

I have reported this bug over a month ago in the xharbour ng with a sample, but no one replied !!!!!

A fix will be opening the file "exclusive"
