Example

/* This example creates an array of selected items and rotates each one. */
/* Note that this can also be done simply by setting a flag in L_AnnRotate.  */
HANNOBJECT hContainer; /* Container annotation object */
void TestAnnSelectItems( HWND hWnd)
{
  L_UINT uSelectCount;    /* Number of objects selected */
  pHANNOBJECT pAnnArray;  /* Pointer to an array of annotation objects */
  HGLOBAL hAnnArray;      /* Handle for memory management */
  L_UINT i; /* Loop counter */
  /* Get the number of objects selected */
  L_AnnGetSelectCount(hContainer, &uSelectCount);
  /* Allocate and lock a storage for the object handles */
  hAnnArray = GlobalAlloc(GPTR, sizeof(HANNOBJECT) * uSelectCount);
  pAnnArray = (pHANNOBJECT)GlobalLock( hAnnArray );
  /* Fill the array of selected objects */
  L_AnnGetSelectItems(hContainer, pAnnArray);
  /* Rotate each selected object */
  for (i = 0; i < uSelectCount; i++)
  {
