xBrowse and SQLRDD bug

[MOISES]

Up

[nageswaragunupudi]

I have tested with this sample with FWH20.04. I found the scrollbar working properly and if we execute DBGOBOTTOM() before invoking the browse, the vertical scrollbar is positioned at the bottom.

Please try this sample on your server, by changing the password, etc.

This is my modified buildx.bat

Code: Select all  Expand view

This is my sample program:

Code: Select all  Expand view

#include "FiveWin.ch"
#include "SQLRDD.Ch"
#include "MySQL.Ch"

REQUEST DBFCDX
REQUEST SQLRDD, SR_MYSQL

function Main()

   local cServer, cDatabase, cUser, cPassword, cConnection, nConnection := 0
   local aData, aStruct

   cServer     := "localhost"
   cDatabase   := "sqlrdd"
   cUser       := "root"
   cPassword   := "??????"

   ? "Start"

   USE STATES SHARED
   aData    := FW_DbfToArray()
   aStruct  := DBSTRUCT()
   CLOSE DATA

   cConnection := "HST="+cServer+";UID="+cUser+";PWD="+cPassword+";DTB="+cDatabase
   MsgRun( "Connecting to Server", "SQLRDD", ;
           { || nConnection := SR_AddConnection( CONNECT_MYSQL, cConnection ) } )
   ? "nConnection =", nConnection

   if nConnection <= 0
      MsgAlert("No conexion. ","Verifique!")
      QUIT
   endif

   RddSetDefault("SQLRDD")
   SR_UseDeleteds(.F.)

   MsgRun( "Creting states table", "SQLRDD", ;
           { || DBCREATE( "states", aStruct, "SQLRDD" ) } )

   MsgRun( "Writing 51 records to states.dbf", "SQLRDD", <||
      USE states EXCLUSIVE NEW VIA "SQLRDD"
      FW_ArrayToDBF( aData )
      CLOSE DATA
      return nil
      > )

   MsgRun( "Using sates.dbf", "SQLRDD", <||
      USE states SHARED NEW VIA "SQLRDD"
      GO BOTTOM
      > )

   XBROWSER "STATES" FASTEDIT SHOW RECID TITLE FWVERSION + " " + RDDNAME()

   DBCLOSEALL()

   SR_end()

   ? "Done"

return nil

//-------------------------------------------------------------------------------------------------------------
 

This is the result:


Notes:
VScrollbar works as expected when the dbf is in natural order (not set to an index) and no filter is set.

I am unable to understand why this is not working at your end.

[MOISES]

First of all, thank you for your time.

It fails when the DBF has an index.

Please add this changes:

Code: Select all  Expand view

USE states SHARED NEW VIA "SQLRDD"
  index on field->CODE TAG NAGES1

  GO BOTTOM

  XBROWSER "STATES" FASTEDIT SHOW RECID TITLE FWVERSION + " " + RDDNAME()

  DBCLOSEALL()

  SR_end()
 

The result is this:

We enhanced VScroll bar compatibility for SQLRDD xbrowse in FWH 2006.

This is the test program:

Code: Select all  Expand view

#include "FiveWin.ch"
#include "SQLRDD.Ch"
#include "MySQL.Ch"
