Brw:VGoBottom() does not work in xBrowse [SOLVED]

[MOISES]

Good morning, Antonio,

To finish solving the problem of xBrowse and SQLRDD, since Nages doesn't answer the messages, I need to be able to move the vertical scroll bar.

However, oBrw:VGoBottom() and SendMsg( VK_DOWN ) do not work. They don't do anything.

Here is an example.

Code: Select all

#Include "FiveWin.Ch"
#include "xbrowse.ch"

#include "hbcompat.ch"



FUNCTION Main()

   use c:\fwh\samples\customer

   TESTBROWSE()

   dbcloseall()


   quit


return nil





function TESTBROWSE()

   local oDlg
   local oBrw

   define dialog oDlg title "Test xBrowse " + cvaltochar(datetime()) from 0,0 to 24,79


    @ 0,0 xbrowse oBrw datasource alias() of oDlg fastedit autocols autosort ;
    SIZE -1, -1 PIXEL

    oBrw:nRowHeight := 25


    oBrw:lAutoappend := .t.
    oBrw:CreateFromCode()


    activate dialog oDlg centered ;
             on init ( oBrw:VGoBottom(), oBrw:oVScroll:SendMsg( VK_DOWN ) )

return nil
 

I'd appreciate your help, since I've been requesting for the fix since December and the customers are extremely pissed off.

Thank you very much. Greetings

Just define the needed position from inside the used DBF
and not from a defined xBrowse row-position like :

activate dialog oDlg centered ;
on init DBGOBOTTOM() // seek or anything else

// on init ( oBrw:VGoBottom(), oBrw:oVScroll:SendMsg( VK_DOWN ) )

regards
Uwe

Hi,

Thank you for your reply.

But I need to force such behaviour in order to get xBrowse work under SQLRDD, as this is the failing issue.

Thanks to Cristobal´s help, this is the fix:

Code: Select all

METHOD KeyCount() CLASS TXBrowse

   TRY
      if Empty( ::aFilter )
         ::nLen   := Eval( ::bKeyCount )
      else
         ::nLen   := Len( ::aFilter )
      endif
      ::lClosed   := .f.

   CATCH
      ::nLen      := 0
      ::lClosed   := .t.
   END


   if ::oVScroll != nil
      ::VSetRange( 1, ::nLen )

      if !::lSqlRDD
        ::VUpdatePos()
      endif
   endif

return ::nLen

There is no need to use this method directly.
