but then.. how can I capture this event?

What could also work for me is if I use an event where I can see if a certain item has changed it's state (LVIS_SELECTED, for instance). Is there an event for this? OnItemChangeState or something?

<code>
void CSkinListControl::OnLvnItemchanged(NMHDR *pNMHDR, LRESULT *pResult)
{
 	LPNMLISTVIEW pNMLV = reinterpret_cast<LPNMLISTVIEW>(pNMHDR);

	static int lola = 20;
	//if ( (pNMLV->uNewState & LVIS_SELECTED) != (pNMLV->uOldState & LVIS_SELECTED))
	if( pNMLV->iItem > -1 && 
		pNMLV->uChanged & LVIF_STATE && pNMLV->uNewState & (LVIS_SELECTED | LVIS_FOCUSED) )
	{
		lola--; // I put a breakpoint here... it's stopping CONSTANTLY.
	}
*pResult = 0;
}

Damn... that reflect message is called whenever the listCtrl wants to draw itself

CListCtrl does not have it's own message pump

The underlying common control handles Windows messages though.
