L_UINT uFormat;

/* format for the annotation data */

L_BOOL bSelected;

/* flag that indicates whether to copy all selected objects, or just the specified object */

L_BOOL bEmpty;

/* flag that indicates whether to empty the clipboard prior to copying the annotation data to it.*/

L_BOOL fCheckMenu;

/* flag that indicates whether to check the automation menu */

Parameter

Description

uFormat

Format for the annotation data. Possible values are:

 

Value

bSelected

Flag that indicates whether to copy all selected objects, or just the specified object. Possible values are:

 

Value

Meaning

 

TRUE

Copy all objects that have the selected property set to TRUE. For getting and setting the selected property, use the LAnnContainer::GetSelectItems and LAnnotation::SetSelected functions.

 

FALSE

Copy only the specified object.

bEmpty

Flag that indicates whether to empty the clipboard prior to copying the annotation data to it. Possible values are:

 

Value

Meaning

 

TRUE

Empty the clipboard before copying data to it.

 

FALSE

Add to the existing data on the clipboard.

fCheckMenu

Flag that indicates whether check the automation menu to see if ANNAUTOTEXT_MENU_COPY has been checked. Possible values are:

 

Value

Meaning

 

TRUE

Check the automation menu to see if ANNAUTOTEXT_MENU_COPY has been checked for the specified object. Only those objects with ANNAUTOTEXT_MENU_COPY checked will be copied.

 

FALSE

Do not check the automation menu to see if ANNAUTOTEXT_MENU_COPY has been checked for the specified object. The copied objects are determined by fSelected only.

Returns

SUCCESS

The function was successful.

< 1

An error occurred. Refer to Return Codes.

Comments

Use the WMF format only for copying for use in another application.

If the annotation object is a container, then to retain scaling and positioning information, this function will always copy the root container, along with the specified object or selected objects. Use the bSelected parameter as follows:

To copy only selected objects in a container, set bSelected to TRUE.

To copy all objects in a container, set bSelected to FALSE.
