Solid Edge ST7 SDK
Determining Document Type
Programmer's Guide > Solid Edge > Determining Document Type

Since all Solid Edge Documents implement the SolidEdgeFramework.SolidEdgeDocument interface, we can use the interface to query generic information about the document before performing specific document environment routines.

See Handling 'Application is Busy' and 'Call was Rejected By Callee' errors for information regarding the use of OleMessageFilter.
