TYMED Enumeration

Provides the managed definition of the TYMED structure.

This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.

Namespace:  System.Runtime.InteropServices.ComTypes
Assembly:  System (in System.dll)

[FlagsAttribute]
public enum TYMED

Member nameDescription
TYMED_HGLOBALThe storage medium is a global memory handle (HGLOBAL). Allocate the global handle with the GMEM_SHARE flag. If the STGMEDIUM pUnkForRelease member is null, the destination process should use GlobalFree to release the memory.
TYMED_FILEThe storage medium is a disk file identified by a path. If the STGMEDIUM pUnkForRelease member is null, the destination process should use OpenFile to delete the file.
TYMED_ISTREAMThe storage medium is a stream object identified by an IStream pointer. Use ISequentialStream::Read to read the data. If the STGMEDIUM pUnkForRelease member is not null, the destination process should use IStream::Release to release the stream component.
TYMED_ISTORAGEThe storage medium is a storage component identified by an IStorage pointer. The data is in the streams and storages contained by this IStorage instance. If the STGMEDIUM pUnkForRelease member is not null, the destination process should use IStorage::Release to release the storage component.
TYMED_GDIThe storage medium is a Graphics Device Interface (GDI) component (HBITMAP). If the STGMEDIUM pUnkForRelease member is null, the destination process should use DeleteObject to delete the bitmap.
TYMED_MFPICTThe storage medium is a metafile (HMETAFILE). Use the Windows or WIN32 functions to access the metafile's data. If the STGMEDIUM pUnkForRelease member is null, the destination process should use DeleteMetaFile to delete the bitmap.
TYMED_ENHMFThe storage medium is an enhanced metafile. If the STGMEDIUM pUnkForRelease member is null, the destination process should use DeleteEnhMetaFile to delete the bitmap.
TYMED_NULLNo data is being passed.

For more information about the TYMED structure, see the MSDN Library.

The common language runtime throws an exception when a COM method in native code returns an HRESULT. For more information, see How to: Map HRESULTs and Exceptions.
