In our development, we found a compiling error in VS2012 with RxInventor.tlb. The compile error looks like:
"error C2556: 'miComponentColumnTypeEnum iPartTableColumn::GetReferencedDataType(void)' : overloaded function differs only by return type from 'iComponentColumnTypeEnum iPartTableColumn::GetReferencedDataType(void)”.
This issue is caused by VS. Microsoft has provided a hotfix which is available at the link.
