LAnnAutomation::SetEncryptOptions

#include "ltwrappr.h"

virtual L_INT LAnnAutomation::SetEncryptOptions(pEncryptOptions, uFlags)

pANNENCRYPTOPTIONS pEncryptOptions;

pointer to a structure that specifies various Encryption options

L_UINT uFlags;

flags that determine which objects to process

Sets the options for the specified Automation annotation object. This object may be in the encryptor or the decryptor state.

Parameter Description
pEncryptOptions Pointer to an ANNENCRYPTOPTIONS structure that specifies the various encryption options to set.
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 ( | ). Possible values are:
  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.

Returns

SUCCESS

The function was successful.

< 1

An error occurred. Refer to Return Codes.

Comments

Use this function to set the encrypt options of an Automation annotation object. To use this function, declare a variable of type ANNENCRYPTOPTIONS, and pass the address of this variable for pEncryptOptions.

Use the LAnnAutomation::GetEncryptOptions function to get the encrypt options of an Automation annotation object. These options are in an ANNENCRYPTOPTIONS structure.
