I would like to have sample codes to 'SetFocus' to a particular child item of a CTreeCtrl. The child info available is its item.lParam value.

Thanx.

Hi,
As i have only the lParam value of the child item, i tried to get the hItem of the child item using the below code.  But i have problem with the GetItem() function.  It returns something that is not what i want. (I think the mask value is not set correctly.) BTW, I am using a CTreeView.

TV_ITEM TVItem ;
TVItem.lParam = (LPARAM) 1001 ; // i only know this lParam value
TVItem.mask = TVIF_PARAM ; //which flag needs to be included here?  

CTreeCtrl& MyTree = GetTreeCtrl() ;
if (MyTree.GetItem(&TVItem) ==  0)
{
    AfxMessageBox("error");
    return -1 ;
}

MyTree.SetItemState(TVItem.hItem, TVIS_SELECTED, TVIF_STATE) ;

This is the code you need:

SetItemState(TVItem.hItem, TVIS_DROPHILITED | TVIS_SELECTED, TVIS_DROPHILITED | TVIS_SELECTED);
