Antonio,

i get this error when dragging the scroll bar to the right, sorry

Error description: Error BASE/1132 Bound error: array access
Args:
[ 1] = A { ... }
[ 2] = N 0

Just to make sure i've done everything correctly,

I modified xBrowse.prg with your modification, then linked the modified prg into my app - is this correct?

Pete

Pete,

Yes, you did it right :-)

Please try it this way:
Code (fw): Select all Collapse
METHOD ColAtPos( nPos ) INLINE ::aCols[ Max( 1, ::aDisplay[ MinMax( If( nPos == nil .or. nPos == 0, 1, nPos ), 1, Len( ::aDisplay ) ) ] ) ]
regards, saludos

Pete,

I guess we just have a missing try :-)
Code (fw): Select all Collapse
METHOD ColAtPos( nPos ) INLINE ::aCols[ ::aDisplay[ MinMax( If( nPos == nil, 1, nPos ), 1, Max( 1, Len( ::aDisplay ) ) ) ] ]


but that may generate an out of bounds error if Len( ::aDisplay ) is zero...

Maybe we could also try, to start it simple:
Code (fw): Select all Collapse
METHOD ColAtPos( nPos ) INLINE ::aCols[ ::aDisplay[ nPos ] ]
regards, saludos

Even this does not work.
This problem arises when we use HScroll thumb with any single column xbrowse, whether it is array or dbf.
We need to trace the problem starting from method hscroll(..)

Yes. The problem is not yet fixed, even in 10.06.
Let us await the fix.
Meanwhile we try to avoid HScroll bar for single column xbrowse.
