LAnnHotSpot::GetSecondaryMetafile

#include "ltwrappr.h"

virtual L_INT LAnnHotSpot::GetSecondaryMetafile(phMetafile)

HMETAFILE * phMetafile;

/* pointer to a variable to be updated with the handle to a metafile */

Retrieves the metafile handle associated with an HotSpot object when it is in the decryptor state.

Parameter	Description
phMetafile	Pointer to a variable to be updated with the handle to a metafile.

Returns

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

Comments

The HotSpot object has two states:

Encryptor

Decryptor

Each state is displayed with its own metafile. Use this function to retrieve the current metafile for an HotSpot object in a decryptor state. The default image is shown in the figure below:

$image\decryptresized20.gif$

If this function is successful, the address pointed to by phMetafile will be updated with the metafile handle.

Use the LAnnHotSpot::GetMetafile function to retrieve the current metafile for an HotSpot object in an encryptor state.
