I'm not 100% sure what you mean, but it sounds like you have a polyline 
shapefile and you are trying to define it as a polygon in your map file. 
You can't do that and that is what the error message is telling you. If 
your data are polyline, specify the TYPE in your layer definition as LINE.

    I use the extents as the shpinfo.exe output and it was OK. I succesfully
generate images with POLYGON type. Now, I face another problem and  I cannot
generate any image when I use a POLYLINE. The error message is:
"msDrawShape(): General error message. Only polygon shapes can be drawn
using a POLYGON layer definition. "
     The docs says POLYLINE does not exist as a type so I am not sure how to
manage it.

                    Mario

These data appear to be in decimal degrees, which is fine.  Make sure
you use UNITS DD in your MAP file, and set the EXTENT to use the values
below.

I have seen certain builds of shpinfo that run correctly and then crash
after generating their output.  Don't worry about it in this case, as
you have the data you need.

Hi,
   I was playing with the demo.map and now I want to use my own
shapefiles
but I do not know the EXTENT of my map..... I downloaded shapelib from
the
Internet and with shpinfo.exe I get:
Info for calles.shp
Polyline(3), 338 Records in file
File Bounds: (   -71.53179836,   -41.29253644)
       (   -71.14854968,   -41.04421467)

Then there is some unknown error . I do not know how to use these values
as
I never saw something like this values (GG.GGGGGGG) in .map file. Can
anybody help me?
