How to Disable the Automatic Loading of the default DICOM Context Group Table

The default DICOM Context Group table is a large table with many entries. When the DICOM library is initially loaded, the DICOM Context Group Table is not initially loaded. It will be automatically loaded the first time it is accessed. Specifically, the first call to any of the following functions will cause the automatic load of the default DICOM Context Group table (if it has NOT already been loaded):

LDicomContextGroup::GetFirst
LDicomContextGroup::GetLast
LDicomContextGroup::GetNext
LDicomContextGroup::GetPrev
LDicomContextGroup::GetCount
LDicomContextGroup::Find
LDicomContextGroup::FindIndex
LDicomContextGroup::Insert
LDicomContextGroup::Delete
LDicomContextGroup::Exists
LDicomContextGroup::GetFirstCodedConcept
LDicomContextGroup::GetLastCodedConcept
LDicomContextGroup::GetNextCodedConcept
LDicomContextGroup::GetPrevCodedConcept
LDicomContextGroup::GetContextGroup
LDicomContextGroup::GetCountCodedConcept
LDicomContextGroup::FindCodedConcept
LDicomContextGroup::SetCodeMeaning
LDicomContextGroup::InsertCodedConcept
LDicomContextGroup::DeleteCodedConcept
LDicomContextGroup::ExistsCodedConcept

To disable the automatic load of the Default DICOM Context Group table, call any of the following functions in your initialization code (before calling any other DICOM functions):

LDicomContextGroup::Load
LDicomContextGroup::Reset
LDicomContextGroup::Default

Therefore, to prevent the default DICOM Context Group Table from automatically loading, call LDicomContextGroup::Reset in your application initialization code.
