Re: [mapserver-users] Displaying query result on the same page?
Thank you, Steve.
It seems frames and/or AJAX are the only way to display query result on the
same page when using CGI MapServer, am I correct?

For frames you just set the form
target to the frame of interest. You're code is quite
close.
Still another option is to use AJAX/AJAST. You issue the
query via an XMLHttpRequest and get the
results back in a javascript string or object that you can
direct the contents of to a container (e.g. div)
on your page.

I hope this newbie question doesn't bother you.
See, I want to display query result on my map page, but if
I use query mode, the query result replaces the whole page.
As workaround, I redirect the query result to a pop-up page
using the following JavaScript:
function toFrame() {
if
(document.mapserv.mode.value ==
query || document.mapserv.mode.value ==
nquery) {
document.mapserv.target = _blank;
} else {
document.mapserv.target = _self;
}
}
However, I'd also like to display the query result as part
of the page (for example, on the lower right of the page),
without replacing the entire page with the query result.
Is there any way to do such thing using CGI MapServer? Or
is PHP MapScript the only way to do it?
I'm thinking about using HTML frames, but I'm still at loss
to redirect the query result to a particular frame.
Many thanks,

Re: [mapserver-users] MapServer with RHEL5
Replying to my own message with further information. I believe the
problem we had is very different than the problem that Andreas Eichner
observed. Our problem becomes a different thing to check for if you
notice odd core dumps.
I also have a request for the mapserver developers so that if someone
else has a similar problem in the future that mapserver will output
errors that indicate the problem, rather than core dump.

I had a problem with GD-2.0.35's configure script not detecting
iconv correctly (see old thread:
http://n2.nabble.com/Confirmation-of-status-of-UTF8-support,-and-where-transcoding-to-Latin-1-may-be-happening.-td1973930.html
The stubs that caused the problem are at
http://cvs.php.net/viewvc.cgi/gd/libgd/src/gdkanji.c?view=markup#l27 ),
so I am compiling 2.0.36RC1. If I load that version of GD instead of
the 2.0.35 used by the systems people, and otherwise use their binaries
and libraries, I do not get the core dump.
This morning I used the little test I wrote in the past to check for the
broken gd.
#include stdio.h
#include /path-to-libiconvs/include/iconv.h
int main() {
iconv_t cd;
cd = iconv_open(UTF-8, UTF-16);
printf(iconv_open returns %d\n\n, (int)cd);
iconv_close(cd);
return 0;
}
gcc -L/mapserv/lib/ -lgd -liconv -o gdbroke gdbroke.c
In the above the iconv.h has to be the one from libiconv, and not the
one that comes with glibc. It is only when you use the iconv.h from
libiconv that this gd bug is tweaked.
If I run the above with the libgd created by our systems folks, I get:
$ ./gdbroke
iconv_open returns -1
If I run against the gd 2.0.36RC1 I compiled, or with iconv.h so that I
use the glibc version of iconv, I get:
$ ./gdbroke
iconv_open returns 146702344
(or some other number that isn't -1)
I have joined the gd-devel mailing list and have asked when 2.0.36 will
be released, which has this odd issue already resolved.
the strings it was trying to compare were NULL. I'm also wondering if
it would be worthwhile to have code that in this case would exit
gracefully with an error message rather than core dumping?
In mapstring.c the common thing to do when iconv_open() returns -1, or
any other error, is to do an msSetError() and then return NULL from the
function.
The problem appears to be that this return code is not checked, and in
many cases the value is assumed to be a pointer to a string. If that NULL
is then used in a manipulation (say, a strdup()) then the program will
core dump. We never get to see the error string as the core dump happens
before the error string is written to the error log.
There are a number of ways to resolve this. One is to always return a
valid string (such as strdup() ) from the function and set a global
error number instead. That way functions that don't check the error code
will simply be manipulating a valid empty string, rather than a null.
The other is to ensure that any call to a mapstring.c string function
checks the return code for NULL. I suspect this will be much more work.
Thanks.

RE: [mapserver-users] Painting outside a polygon.
I am not sure if this meets your case or not. If you simply want to set the background color of the map to blue, you can set IMAGECOLOR 0 0 255 at the map level. (of course, you may want to pick a nicer shade of blue...) http://mapserver.org/mapfile/map.html This will put a blue background behind in the areas not covered by your polygons.

Re: [mapserver-users] Displaying query result on the same page?
You can probably do it with query/browse templates but the other methods are
more efficient and provide a better user experience and are easier to configure.

Re: [mapserver-users] Painting outside a polygon.
If you are looking to make one specific feature inside a shapefile with multiple features clear or transparent you can use the FILTER parameter within the LAYER definition. In addition to setting the IMAGECOLOR at the map level to the same color as your layer it may give you the results you desire. Following are two examples of using the FILTER parameter to make one part of a shapefile layer disappear. It uses a field in the attributes called shapeid you could use any field in your shapefile. # the following will make feature with shapeid 12345 transparent and leave the rest of the shapefile with default color rules FILTER ( [shapeid] != 12345 ) # the following variation would use the shapeid= parameter provided in the URL of cgi mapserver FILTER ( [shapeid] != %shapeid% ) -Trent Ernesto Barrera wrote: Hi there, I'm dealing with a layer containing polygon data for a given country (shapefile).
