My application will not recognize my KML file. The application will go to the correct location (lat/long) and zoom level, but will not recognize the KML file location. I have attempted to use two different servers to check the problem, so I believe it is the code that is the problem.

Your kml file does not exist.
http://webgis.uwm.edu/engelki7/KMLFiles/Richfield_Homes2.kml
Gives me: HTTP Error 404 - File or directory not found
If you believe it is there (the path on the server is correct), then it is possible that the server doesn't know how to deal with kml/kmz files. See this portion of the documentation on kml files.

In the basic sample code below I use the following code to catch zoom_changed event:
google.maps.event.addListener(map, 'zoom_changed', function() {
console.log(map.getZoom());
});
If I call map.setZoom(30), I get this into console:
> map.setZoom(30)
> 30
> 21
That is, the zoom_changed is fired twice and once with incorrect value. It causes me some problems in libraries and I don't know why this happens. However, I can't reproduce the issue on some other projects with v3 api.
Strange thing is that if I specify the zoom_changed listener additionally in console instead of putting it into initialize, I get values: 21, 21. So the answer is there somehow.
The code is:

I am using Google maps JavaScript API, i get users zip code from database, find lang, lat for it from another table, pass it to JavaScript and show marker on the map.this is showing marker perfectly.
But i want to show marker on exact address of the user instead of just zip code.
But unable to find a way how to do this.
Can anybody please guide me.
Thanks
if you want to place the marker on given lat and lng use this code,
use this code

I have following codes. It works perfectly in IE (GML and GeoJSON vector layer was loaded), but not in Firefox and Chrome without any errors noticed. Please help me to fix this problem.
Here is the code with GML vector layer (I just used built-in layer in Geoserver, so you can download and test it without any modification):

I prepared a simple page by using the data of a fusion table. ( FusionTablesLayer with Google Maps JavaScript API v3 ) but the map is not displayed. You can see the page here: http://www.siterary.com/0test.html . What's the problem ? The code is as below

The file "/maps/documentation/javascript/examples/default.css" doesn't exist on your site. Your map doesn't have a valid size.
Working version
code snippet:
function initialize() {
var istanbul = new google.maps.LatLng(41.01, 28.97);
map = new google.maps.Map(document.getElementById('map_canvas'), {

I have a written a simple code which would display the location on the google map. But for some reasons its not showing up. Any idea whats happening?

<script type="text/javascript">

var latlng = new google.maps.LatLng(57.8, 14.0);
var options = {

};
var map = new google.maps.Map(document.getElementById('map'), options);
}
})();
</script>

You need to set dimensions for your map container, try this:
<style type="text/css">
#map {
width: 500px;
height: 500px;
}
</style>
