Oh shit !!
You're right !
By not providing a bounding box in the url, I think that mapserver is doing
a mistake and takes the coordinates of the extent present in the map file
and converts them into the srs of the request !
So by simply puting -180,-90,180,90 in the url as the bounding box, I now
see my points !!!!
Really sorry for those unnecessary emails !
Thank you for having helped me ! ;)

Hi,
This is mostly guessing, but could it be that there is some conflict due to
that you are using epsg:4326 in your request but mapfile extents are in some
other projection? What happens if you change the SRS in the request to suit
the map level projection? Of course it must be added to wms_srs
list first.

Given all this, I first tried to render this with a web browser by writing
directly my request :
http://acquisitiontest/CGI/bin/mapserv.exe?request=GetMap&map=C:/temp/bch/Shell.map&request=GetMap&layers=Vector&srs=EPSG:4326&version=1.1.1&styles=
By not giving the extent nor width and height, I am expecting to take the
full bounding box of the map file as width and height. I am already doing
this for raster layers so I won't be surprised to make it work for shape
files.
But, unfortunately, the result remains empty whatever I try.
So, I remembered to use the shp2img to make a render and there I have a
correct result.
From what I remember to have read on the mailing list mapserv.exe and
shp2img.exe are equivalent. So am I surprised to get different results.
I am sorry but I can not give any source shape files as their content are
confidential but if anyone think it could be helpful I can try to take one
and remove all but one lines in it.
Thank you in advance for any idea to make the thing go on !!!
Benoît
