You can't reference a variable within the dwModify string. You have to
do:

dw_pict.dwModify("create bitmap(band=header x='0' y='0' height='961'" &
 +  "height='961' width='1171' filename=~'"+filename+"~' name=picture)")

Why not just create a picture control in your window?

1. REPOST: how to dynamically load a color in excel spread sheet

Is there a way I can change color of a row in an excel sheet depending
on a certain column value .

i.e if assuming " 1st column " is the key value , and if it's value is
1 , I want that row to be of "red" color .. If it's 2 I want that row
to be of color "yellow" etc.

Can I do this dynamically in excel.

If not , can I do this in a html file, which reads this excel sheet

thanks
