A little bit of help?

if (PtInRect(SlotCustom->rect, point))

if (clock() < m_tmCoolDown || m_bStopCoolDown)
{
return;
}


if (g_WndMng.m_pWndTaskBar->m_nExecute == 0)
{
if ((g_WndMng.m_pWndTaskBar->m_nUsedSkillQueue == 0) && (m_nActionSlot > 0))
{
g_WndMng.m_pWndWorld->m_dwNextSkill = NEXTSKILL_ACTIONSLOT;
}
}
}

void CWndTaskBarInterface::OnLButtonUp( UINT nFlags, CPoint point)
{
LPSHORTCUT pShortcut = NULL;


if(!CWndTaskBarInterface::IsLock())
*m_bPick = FALSE;

for( int i = 0; i < 10; i++ )
{
if( !m_bCtrlVisible[i] )
continue;
if( wndCtrl[i]->rect.PtInRect( point ))
{
pShortcut = m_pSlotItem[ i ];
m_USEFireALPHA[i] = 255;
}
}
if( pShortcut && pShortcut == m_pSelectShortcut && !pShortcut->IsEmpty() && pShortcut->m_dwData != 2 )
{
g_WndMng.ObjectExecutor( pShortcut );
}

ReleaseCapture();
}
