Hello,
I am using ArcObjects 10.1 to read an MXD and am trying to export all of the layers inside of it to shapefiles. I am first getting the featureclass from the layer by using:
However sometimes the FeatureClass is null. This doesn't happen in my environment when I'm testing both within and outside of Visual Studio. However once someone else runs the code against the same MXD then the FeatureClass is null. I have checked the MXD they are using and the links to the data are not broken. It is successfully opening the MXD because I am able to extract the symbol information, but it's just not able to read the data.
Can anyone think of any other reason that this might be returning null? Is there something else I should be asking them to look at in their environment for why this is happening? Any help would be greatly appreciated.

IFeatureLayerDefinition2 featureDefinition = (IFeatureLayerDefinition2)featureLayer; IQueryFilter queryFilter = new QueryFilterClass(); queryFilter.WhereClause = featureDefinition.DefinitionExpression; queryFilter.SubFields = "*"; IFeatureClass featureClass = featureLayer.FeatureClass; IDataset dataset = (IDataset)featureClass; IFeatureClassName inFCName = (IFeatureClassName)dataset.FullName;

The real tricky thing for me was that I created a python script to run through the mxd doing the export as well, and that worked just fine, it exported everything to shapefiles, but yet still when trying to access via ArcObjects it comes back null.
I am well and truly stumped.
