<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Hello everybody,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am maintaining a system for a customer that links to mapserver -- we’re not mapserver users, they are.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Some time back, when they used mapserver v5.6, we put a partial mapserver CGI url in one of their configuration files. The idea was that they could edit it if they ever needed to in future, e.g. if they changed sever location for mapserver.
They later upgraded to mapserver 6.0, but cjust changing the target server failed.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The original query substring was along the lines of:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><a href="http://someserver.ourcustomer.co.uk/MapServer/cgi-bin5.6/mapserv.exe?map=D:\Maps\CCC\Intranet52\_MapServerConfig\Surveys.map_AND_mode=ITEMNQUERYMAP_AND_qlayer=Buildings_AND_map.layer%5bBuildings%5d=TEMPLATE+'_MapServerTemplates\Buildings_fields.xml'_AND_qitem=SHORT_CODE_EMS_AND_qstring">http://someserver.ourcustomer.co.uk/MapServer/cgi-bin5.6/mapserv.exe?map=D:\Maps\CCC\Intranet52\_MapServerConfig\Surveys.map_AND_mode=ITEMNQUERYMAP_AND_qlayer=Buildings_AND_map.layer%5bBuildings%5d=TEMPLATE+'_MapServerTemplates\Buildings_fields.xml'_AND_qitem=SHORT_CODE_EMS_AND_qstring</a>=
{application adds the rest here depending on what the user wants on that invocation}<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I looked at the 5.6 to 6.0 migration guide at <a href="http://www.mapserver.org/MIGRATION_GUIDE.html#mapserver-5-6-to-6-0-migration">
http://www.mapserver.org/MIGRATION_GUIDE.html#mapserver-5-6-to-6-0-migration</a> and in the CGI section it says:<o:p></o:p></p>
<p class="MsoNormal"> All of the query map related modes (e.g. NQUERYMAP, ITEMQUERYMAP, etc...) have been removed in favor of using the “qformat” parameter. That parameter takes an output format name or mime/type as a value and uses that to process a set
of query results. For example:<o:p></o:p></p>
<p class="MsoNormal">...&mode=nquerymap&... would become ...&mode=nquery&qformat=png24&...<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So I tried a simple substitution in line with that and changed our substring to:<o:p></o:p></p>
<p class="MsoNormal"><a href="http://vishare.cardiff.gov.uk/mapserv6/cgi-bin6.0/mapserv.exe?map=D:\Maps\CCC\Intranet52\_MapServerConfig\Surveys.map_AND_mode=ITEMNQUERY_AND_qformat=png24_AND_qlayer=Buildings_AND_map.layer%5bBuildings%5d=TEMPLATE+'_MapServerTemplates\Buildings_fields.xml'_AND_qitem=SHORT_CODE_EMS_AND_qstring">http://<span style="color:windowtext;text-decoration:none">
</span>someserver.ourcustomer.co.uk /mapserv6/cgi-bin6.0/mapserv.exe?map=D:\Maps\CCC\Intranet52\_MapServerConfig\Surveys.map_AND_mode=ITEMNQUERY_AND_qformat=png24_AND_qlayer=Buildings_AND_map.layer%5bBuildings%5d=TEMPLATE+'_MapServerTemplates\Buildings_fields.xml'_AND_qitem=SHORT_CODE_EMS_AND_qstring</a>=
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">…i.e. I changed the target from the 5.6 to 6.0 server and changed “mode=ITEMNQUERYMAP” to “mode=ITEMNQUERY_AND_qformat=png24”<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This did not meet with success, I got a “Parameter is not valid” error with the following stack trace:<o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Verdana",sans-serif">[ArgumentException: Parameter is not valid.]<br>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Superficially, this error doesn’t seem to have much to do with the parameter I changed.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">At this point, I would like to ask some more experienced mapserver users a few questions:<o:p></o:p></p>

</span></span><![endif]>Does the error message received look like the sort of thing that would apply to the rest of the CGI query, i.e. the stuff that’s added on the end to suit the specific user request?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m really hoping for 2, because otherwise I’ll have to get our legacy application running and then learn mapserver syntax to change what it’s sending.<o:p></o:p></p>
