HMETAFILE hMetafile;	/* handle to a metafile */
L_UINT uType;	/* constant that indicates the metafile to set */
L_UINT uFlags;	/* flags that determine which objects to process */

Sets the metafile for an Encrypt object.

Parameter	Description
hMetafile	Handle to a metafile.
uType	Constant that indicates the metafile to set. Possible values are:
	Value	Meaning
	ANNMETAFILE_USER	[0x7FFF] user-defined metafiles
	ANNMETAFILE_APPROVED	[0] predefined metafiles - APPROVED
	ANNMETAFILE_ASSIGNED	[1] predefined metafile - ASSIGNED
	ANNMETAFILE_CHECKED	[2] predefined metafile -CHECKED
	ANNMETAFILE_CLATPRV	[3] predefined metafile - CLIENT ATTORNEY PRIVILEGE
	ANNMETAFILE_COPY	[4] predefined metafile - COPY
	ANNMETAFILE_DRAFT	[5] predefined metafile - DRAFT
	ANNMETAFILE_EXTENDED	[6] predefined metafile - EXTENDED
	ANNMETAFILE_FAX	[7] predefined metafile - FAX
	ANNMETAFILE_FAXED	[8] predefined metafile - FAXED
	ANNMETAFILE_IMPORTANT	[9] predefined metafile - IMPORTANT
	ANNMETAFILE_INVOICE	[10] predefined metafile - INVOICE
	ANNMETAFILE_NOTICE	[11] predefined metafile - NOTICE
	ANNMETAFILE_OFFICIAL	[12] predefined metafile - OFFICIAL
	ANNMETAFILE_ONFILE	[13] predefined metafile - ON FILE
	ANNMETAFILE_PAID	[14] predefined metafile - PAID
	ANNMETAFILE_PASSED	[15] predefined metafile - PASSED
	ANNMETAFILE_PENDING	[16] predefined metafile - PENDING
	ANNMETAFILE_PROCESSED	[17] predefined metafile - PROCESSED
	ANNMETAFILE_RECEIVED	[18] predefined metafile - RECEIVED
	ANNMETAFILE_REJECTED	[19] predefined metafile - REJECTED
	ANNMETAFILE_RELEASE	[20] predefined metafile - RELEASE
	ANNMETAFILE_SENT	[21] predefined metafile - SENT
	ANNMETAFILE_SHIPPED	[22] predefined metafile - SHIPPED
	ANNMETAFILE_TOPSECRET	[23] predefined metafile - TOP SECRET
	ANNMETAFILE_URGENT	[24] predefined metafile - URGENT
	ANNMETAFILE_VOID	[25] predefined metafile VOID
	ANNMETAFILE_ENCRYPTOR	[27] predefined metafile for an encrypt object in the encryptor state
	ANNMETAFILE_DECRYPTOR	[28] predefined metafile for an encrypt object in the decryptorstate
uFlags	Flags that determine which objects to process. Most of the flags apply only to container objects. You can combine values when appropriate by using a bitwise OR ( \| ). The following are valid values:
	Value	Meaning
	0	Process only the specified object.
	ANNFLAG_SELECTED	[0x0001] Process only objects that have the selected property set to TRUE. For getting and setting the selected property, use the LAnnotation::IsSelected and LAnnotation::SetSelected functions.
	ANNFLAG_NOTTHIS	[0x0004] Process only one level of objects within the specified container, not the container itself. If there are containers within the container, they are modified, but the objects within them are not.
	ANNFLAG_RECURSE	[0x0008] Process objects within a container, and within any subcontainers, down to any level.
	ANNFLAG_NOTCONTAINER	[0x0002] (Used with ANNFLAG_RECURSE) Process objects within containers, not the containers themselves.
	ANNFLAG_NOINVALIDATE	[0x0010] Do not invalidate the affected rectangle in the window. Use this to avoid generating unwanted paint messages.
	ANNFLAG_CHECKMENU	[0x0020] Process objects only if the ANNAUTOTEXT_MENU_METAFILE menu item has been selected.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

Only Encrypt objects, hotspot objects, stamp objects, and freehand hotspot objects can have metafiles. Note that for Encrypt objects, setting the metafile destroys the Encrypt objects bitmap and text. Also, setting a bitmap or text destroys the metafile associated with the Encrypt object.

If uType == ANNMETAFILE_USER, then hMetafile is the metafile handle. You can use any of the windows functions to create a metafile.

If uType is one of the ANNMETAFILE_XXX values, then hMetafile is ignored and the default metafiles are used instead. The annotation DLL has 25 predefined metafiles. You can change the predefined metafiles by using LAnnotation::SetPredefinedMetafile.
