Example

This example deletes even numbered bitmaps from a list.

 L_INT DeleteBitmapListItemsExample(HBITMAPLIST hList)
{
   L_INT nRet;
   L_UINT i;      /* Loop counter */
   L_UINT uCount; /* Number of bitmaps in the list */

   /* Delete even numbered bitmaps from the list */
   nRet = L_GetBitmapListCount(hList, &uCount);
   if(nRet != SUCCESS)
      return nRet;
   for (i = 0; i <= uCount/2; i ++)
   {
      nRet = L_DeleteBitmapListItems(hList, i, 1);
      if(nRet != SUCCESS)
         return nRet;
   }
   return SUCCESS;
