AcMapIEExporter::ResetDataTypeForProperty Method

Sets the Data Type for new or existing properties.

virtual AcMapIE::ErrCode ResetDataTypeForProperty(
    const ACHAR* schemaName, 
    const ACHAR* className, 
    const ACHAR* propertyName, 
    AcMapIE::DataType dataType
) = 0;

kErr_OK if successful 

kErr_ClassExists if the property is not a newly appended one 

kErr_InvalidMapping if the property is not mapped to 

kErr_InvalidDataStore if the target datastore is not supported (FDO)

Normally the data type is automatically determined based on the source data type. This setting allows the type to be reset to another type so that expressions can be used to convert the source type. For example, a source type of .Color can be mapped to Reals as pipe diameters. This cannot be used on already existing properties.
