I write again and I hope somebody is going to answer me...
Now I use this function but it works only with Point layer and if I try to
zoom after or before it doesn't work...
function addSelection(nX ,nY,nX2 ,nY2){
   var queryCoords = nX + "," + nY + "," + nX2 + "," + nY2;
   var img = CWCDHTML_GetImage( 'MapLayerDivImg' );
   var str_gMap=gMapDHTMLURL .split("&UniqId=");
   mg.src = str_gMap[0] + "&run_query=1&gszQueryCoords=" + queryCoords ;
   window.status = img.src;

I also have tried with this function that create a new layer with a point
using the existing jsapi function but it doesen't work for me.
function AddSel(nX ,nY,szName){
    goCWCJSAPI.oMap.CreateNewLayer("tmp_"+szName, "POINT", 1);
    // var layer_orig=goCWCJSAPI.oMap.GetLayerByName(szName);
    var layer_sel=goCWCJSAPI.oMap.GetLayerByName('tmp_'+szName);
    // layer_sel=layer_orig;
    var p=new CWCPoint();
    p.x=nX ;
    p.symbol_outlinecolour = "255,255,255";
    goCWCJSAPI.oMap.AddPoint("tmp_"+szName, p);

I think that the right way to approch to the problem is
I am not able to make it work. I wait for some pieces of advice!
Tanks Federica.

Hi everybody,
