This function checks whether the action is active or not, if not the function will remove it.

L_INT LImageViewer_RemoveActionExample(LImageViewerCell& ImageViewerCell) 
{ 
   L_INT    nRet; 
   L_BOOL   bActive; 
   L_INT    nAction = CONTAINER_ACTION_OFFSET; 
   L_UINT   uVk1, uVk2, uVk3, uVk4, uModifiers; 
   // Is the action attached to one of the mouse buttons. 
   bActive = ImageViewerCell.IsActionActive( nAction , 0); 
   if (!bActive) 
   { 
      // Check whether a keyboard shortcut is assigned to action or not. 
      nRet = ImageViewerCell.GetKeyboardAction(nAction , CONTAINER_MOUSEMOVE_DOWN, &uVk1, &uModifiers, 0); 
      if(nRet != SUCCESS) 
         return nRet; 
      nRet = ImageViewerCell.GetKeyboardAction(nAction , CONTAINER_MOUSEMOVE_DOWN, &uVk2, &uModifiers, 0); 
      if(nRet != SUCCESS) 
         return nRet; 
      nRet = ImageViewerCell.GetKeyboardAction(nAction , CONTAINER_MOUSEMOVE_DOWN, &uVk3, &uModifiers, 0); 
      if(nRet != SUCCESS) 
         return nRet; 
      nRet = ImageViewerCell.GetKeyboardAction(nAction , CONTAINER_MOUSEMOVE_DOWN, &uVk4, &uModifiers, 0); 
      if(nRet != SUCCESS) 
         return nRet; 
      // If there is no keyboard shortcut assigned to the action the function will remove it. 
      if ((!uVk1) && (!uVk2) && (!uVk3) && (!uVk4)) 
      { 
         nRet = ImageViewerCell.RemoveAction(nAction , 0);
