Hi Eoinyp,
I watched your code. I think you made a mistake with the zoom level on the
function map.setCenter().
Try to modify the line like that:
map.setCenter(new OpenLayers.LonLat(17, 43), 12);
It should work ;)
Here is the copy of your code that I used and modify:
map = new OpenLayers.Map("map");
map.addControl(new OpenLayers.Control.LayerSwitcher());
//create layer
var velayer = new OpenLayers.Layer.VirtualEarth(
"Roads Layer",
{
'type': VEMapStyle.Road
}
);
var velayer2 = new OpenLayers.Layer.VirtualEarth(
"Aerial Layer",
{
'type': VEMapStyle.Aerial
}
);
map.addLayers([velayer, velayer2]);
map.addControl(new OpenLayers.Control.PanZoomBar());
map.addControl(new OpenLayers.Control.ScaleLine());
map.addControl(new OpenLayers.Control.MousePosition());
map.setCenter(new OpenLayers.LonLat(17, 43), 12);
Sincerly,
Jérome
