I tried to set map center by method setCenter, but still not working. Map is not moving. I tried to used transform from projection to map projection and without successful. Here is part of code. Thanks.
<script type="text/javascript">
var lon = 15.869378; //WGS LL84
var lat = 49.528964;
var zoom = 5;
var map, layer;
function init(){
map = new OpenLayers.Map('map');
layer = new OpenLayers.Layer.TMS("Name",
"[URL]",
{ 'type':'png', 'getURL':get_my_url });
map.addLayer(layer);
var markers = new OpenLayers.Layer.Markers( "Markers" );
map.addLayer(markers);
markers.addMarker(new OpenLayers.Marker(new OpenLayers.LonLat(lon, lat).transform(
new OpenLayers.Projection("EPSG:4326"),
map.getProjectionObject())));
map.setCenter(new OpenLayers.LonLat(lon, lat).transform(
new OpenLayers.Projection("EPSG:4326"),
map.getProjectionObject()), zoom);
}
</script>

Reset to default 4I think it may caused by wrong map projection, in your map you should set map projection (I use EPSG:900913 in the example), such as:
map = new OpenLayers.Map('testmap', {
numZoomLevels: 10,
projection: new OpenLayers.Projection("EPSG:900913"),
displayProjection: new OpenLayers.Projection("EPSG: 4326")
});
if you don't do that, map.getProjectionObject() will still get the EPSG:4326 projection.
The marker is shown exactly in the point where it should be?
Anyway, try this:
map.setCenter(new OpenLayers.LonLat(lon, lat).transform('EPSG:4326', 'EPSG:3857'), zoom);
