Paul,
Using local references as in my previous e-mail you do not need to call SetResourceData at all. With SHP just reference a directory like this:
<?xml version="1.0" encoding="utf-8" ?>
<FeatureSource xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xsi:noNamespaceSchemaLocation="FeatureSource-1.0.0.xsd">
<Provider>OSGeo.SHP.3.0</Provider>
<Parameter>
<Name>DefaultFileLocation</Name>
<Value>C:\MyData</Value>
</Parameter>
</FeatureSource>
MapGuide will automatically expose each SHP file in the C:\MyData folder as a Feature Class. Just make sure each SHP file has a PRJ file that MapGuide supports via Proj.4 and you are all set. Note that Studio will not show the SHP files in the Feature Source editor, but that does not mean anything in this case. Studio is just showing the result of enumerating the data associated with the resource (e.g. being managed by that resource). In this case you are managing the data, not MapGuide so it shows nothing.
FYI - I seem to recall a bug with the SHP FDO Provider where all of the data in a directory needs to use the same projection, so you might want to watch out for that.

ahhh ... thats the trick.
When I looked at an uploaded shape file using GetResourceContents
<?xml version="1.0" encoding="utf-8"?>
<FeatureSource xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xsi:noNamespaceSchemaLocation="FeatureSource-1.0.0.xsd">
<Provider>OSGeo.SHP.3.0</Provider>
<Parameter>
<Name>DefaultFileLocation</Name>
<Value>%MG_DATA_FILE_PATH%</Value>
</Parameter>
</FeatureSource>
it didn't seem to list the actual files so I wasn't sure what I could
do with this and SetResourceContent. Using EnumerateResourceData
listed the actual files but there didn't seem to be a way to put this
XML back into the server. Now that I look at the schema for the
feature source, I realize that I could probably just have multiple
Parameter tags, one for each file, and used SetResourceContent :)
Cheers
Paul
