New Post: Problem with display image insted of point.

Hi all
I have problem again.

I use code below(see line 2.) to display image insted of point.

ct = sfDepth.Categories.Add("d3")
ct.Expression = "[HIGHT] = 20 "
ct.DrawingOptions.PointType = MapWinGIS.tkPointSymbolType.ptSymbolPicture
ct.DrawingOptions.Picture = Img3
sfDepth.Categories.ApplyExpressions()

It's work for me.

In line 2 when I use
ct.Expression = "[COLOR] = green "
it's not work .

I know that fieldtype of [HIGHT] is integer but field [COLOR] is string.

How can I do ???

ps. I see link below but I cant do.
