[PaPi]

Hi all, see you please my program:

CODE:
stringgrid2_test  by PaPi  28.02.2010
object myform as form
     autosize=true
     onactivate=main
     object SG as stringgrid
           colcount=4
           rowcount=8
           height=220
           width=280
     end object ` sg
end object ` myform
myform.ShowModal

`------------------------------------------------------
sub Main()
     dim i as integer, j as integer
     for i=0 to SG.colcount
           for j=0 to SG.rowcount
                 sg.cell(i,j)=str$(i)+str$(j)
           next j
     next i
     showmessage SG.text ` this statement give bad result in the last row. WHY???
end sub ` Main
