Thanks Antonio,
But I must use Wbrowse of Hernan Ceccarelli because I use height and color variable and other..
And I use a listbox but there are ARRAY type amat[x,y] with
oBrw:SetArray( aMat )
I try with Tmultiselect of Wbrowse ( Ceccarelli) but it want an alias
I try with asekections() ( Wbriwse standard) but it make error
the user must select only on (vertical) column and not for Row ( orizontal)
Example: I must select the day 5.09.2006 from 08:00 to 12:30
see the picture here to understand it:
