Example

For complete sample code, refer to the ANNOTATE example. This example shows how an active object’s tag can be used to invoke a particular action.

 L_INT AnnGetTagExample(HANNOBJECT hAnnObject)
{
   L_INT nRet;
   L_UINT32 ObjectTag;     /* Tag used to identify an object */
   L_UINT   ActiveState;   /* Specifies whether the object can be activated */

   /* Get the tag and the active state */
   nRet = L_AnnGetTag(hAnnObject, &ObjectTag);
   if(nRet != SUCCESS)
      return nRet;
   nRet = L_AnnGetActiveState(hAnnObject, &ActiveState);
   if(nRet != SUCCESS)
      return nRet;
   /* Take an action based on the tag and the active state */
   if ((ObjectTag == 3) && (ActiveState == ANNACTIVE_ENABLED))
      MessageBox (NULL, TEXT("This is what we do for No. 3"), TEXT("Notice"), MB_OK);
   return SUCCESS;
