Google Map Version - google-maps

Hi I am Using Google Map Version 2 in my asp.net web application. now my problem is the in map area GMAPEZ is displaying and nothing else and i have no error in my XML File with valid Google Map key. What could be the problem

You declare your map type as G_MAP_TYPE on line 766 of gmapez-2.js.
var mapType = G_MAP_TYPE;
You probably want to do one of the standard map types:

I found this in a few seconds using the Chrome Developer Tools. Here's a good reference so you can do the same:

FusionTablesLayer not working with google maps version 3.22/3.23

we have a problem with our fusion table implementation when using google maps versin 3.23 (exp) or 3.22 (stable). With these versions, when we are trying to create a layer, we get Uncaught TypeError: Cannot read property 'stack' of undefined. The following lines in our code is not working with 3.23 or 3.22:
layer = new google.maps.FusionTablesLayer({
query: {
select: 'Full address',
from: selectedFusionTableId,
where: sql
},
options: { suppressInfoWindows: true },
styleId: 1,
templateId: selectedFusionTableInfoWindowTemplateId
});
The implementation has been working with google maps version 3.21 (current frozen version) for a year, so I wonder if there are something we can do on our side or if there is something broken in the google maps versions 3.22 and 3.23?
Since google maps is using version rollover, our implementation will stop working next time google updates googlemaps versions.
Application can be found here:

I'm unable to reproduce the problem from a simple embedded map using "Tools > Publish" and changing the Maps API version. I suspect there's something going on with your app that is different from that code; can you reproduce using the generated Fusion Tables publish HTML?
BTW, the code above works, but it would be cleaner to use options for style and template IDs, e.g.,
options: {
suppressInfoWindows: true,
styleId: 1,
templateId: selectedFusionTableInfoWindowTemplateId
}
The problm was finally found in our code and it was caused by a global js function called Error(). Changing the name on the function to a more specific name resolved the issue and our application started to work against google maps version 3.22 and 3.23. Our guess is that Error() function conflicted with a function with the same name in google maps js file.

Program-generated KML file validates, but doesn't work

I had a co-worker that normally worked with Google Maps and now I am creating my first map. I am using what they developed in the past and making the changes for what I need. They created a script that sets some of the map defaults, so that is why things might look slightly different.
var map = new Map();
map.loadMap();
var kml = new google.maps.KmlLayer({ url: 'http://api.mankatomn.gov/api/engineeringprojectskml', suppressInfoWindows: true });
kml.setMap(map.map);
The map loads. My KML file doesn't load. I don't get any errors in the console. When I replace the url with a different URL http://www.mankato-mn.gov/Maps/StreetConstruction/streetconstruction.ashx?id=122 it'll work just fine. My new feed does validate. Is there a issue with my web service?
Update: After a few days, I am still having the issue. So I am pretty sure this isn't a DNS issue anymore. I created a jsFiddle to see if it is my code or something else. I started with Google's sample code and changed the URL of the KML file to both my web service and to a static version of the generated file. Both are valid KML files. Neither work. If there was a syntax error, wouldn't the API report that?
You can get the status of a KML layer with
kml.getStatus();
which in this case return:
"INVALID_DOCUMENT"
Now, if I request your URL from the browser, I get
<Error>
<Message>An error has occurred.</Message>
</Error>
So it seems if there ever was a valid KML there, it isn't anymore. Assuming from your question I can oly guess it was above weight limit, or you weren't associating it with a valid instance of map.
For getStatus to return something useful, you must wait for Google Maps API to try and load the KML layer you declared. For example, you can add a listener on the status_changed event.
var kmloptions={
url: 'https://dl.dropboxusercontent.com/u/2732434/engineeringprojectskml.kml',
suppressInfoWindows: true
};
var newKml = new google.maps.KmlLayer(kmloptions);
newKml.setMap(map);
google.maps.event.addListenerOnce(newKml, 'status_changed', function () {
console.log('KML status is', newKml.getStatus());
});
in this case (note that I'm using the alternative URL you used in the jsFiddle), I still get INVALID DOCUMENT.
Update: it seems the problem was the encoding of the file (UTF-16 BE is meant to be binary). I converted it to utf-8 and reindented (it's in my public dropbox now)
You can check if the DNS is setup by:
Going to the url in your browser. Do this with cache emptied and history ereased (private mode is best). If it ends up at your server and the right file it is not a DNS problem.
Move the file to a location you're sure it is reachable without any DNS issues. e.g. http://www.mankato-mn.gov/Maps/StreetConstruction/engineeringprojectskml
If the problem persists make sure that your KML syntax and Javascript is 100% correct. Also check out https://developers.google.com/maps/documentation/javascript/examples/layer-kml if you're still having any issues.

How to do Chart on Windows Phone Universal App

I'm new Windows Phone Universal App, I need to implement bar/pie chart.
Tried many dll, Metro UI, WinRtXamlToolKit and WinRtXamlToolKit.Controls.DataVisualization
These dll are not working.
Give me good idea to do this on Windows Phone Universal App. How to do chart programmatically.
Thanks
I believe the Telerik has some Chart libraries that cost money ( can't link though as stackoverflow only permits me to post 2 links ( less than 10 rep) ). I have not used it and it is in Beta version at the moment. Google "Rad Chart windows universal apps" and you can read about it.
When I have needed charts for universal apps i have used the Google Chart Tools. You can use https://developers.google.com/chart/image/ even though Google is not developing on it anymore. It is is freakingly easy to use if you do not want to spend time drawing your own Charts. With the API you can request a chart just through a http request. You can setup almost everything and it's really easy to use thanks to the well documented API.
Here is an example of a bar chart i made using the API.
http://chart.googleapis.com/chart?chtt=Karakterfordeling&cht=bvg&chof=png&chs=300x300&chxt=x,y&chco=0076A3&chf=bg,s,65432100&hxr=0,0,50&chxl=0:|2|4|7|10|12&chxr=1,0,20&chbh=40,0,10&chd=t:2,60,70,10,90
All the arguments are passed through the http request and you can set your Chart up using the Live Chart Playground:
These are the arguments for the http request posted above. You can use the Live Chart Playground to set up parameters like below.
chtt=Karakterfordeling
cht=bvg
chof=png
chs=300x300
chxt=x,y
chco=0076A3
chf=bg,s,65432100
hxr=0,0,50
chxl=0:
2
4
7
10
12
chxr=1,0,20
chbh=40,0,10
chd=t:2,60,70,10,90
In code you set the http string as your ImageSource. You can manipulate the http string in your code and adapt the chart parameters/data if needed. I would recommend using a Converter that you bind to from you XAML. Pass your data to the converter and let it return a ImageSource with the http request. If you are new to Converters you can probably find a few posts about it here on stackoverflow.
Don't use DLLs grab the files into your project.
Add WinRTXamlToolkit.Controls.DataVisualization.csproj to your solution and reference it in the main project and add this to your page.
xmlns:charting="using:WinRTXamlToolkit.Controls.DataVisualization.Charting"
xmlns:datavis="using:WinRTXamlToolkit.Controls.DataVisualization"
Look at the samples project http://winrtxamltoolkit.codeplex.com
Unfortunately, winrtxamltoolkit is only for WinRT; VS 2013 doesn't allow adding of project references of that kind to WinPhone projects.

Google map supports ArcGISDynamicMapServiceLayer from ESRI API?

i believe that in google API version 2, it could eventually call this method out. Moreover they do share or happen to be using the same type of coding.
However in version 3, i could not set this layer to the map neither via "layer.setMap(map)" because this esri method does not has this function , nor "map.addOverlay(layer)" because this function belongs to version 2 which has been taken down. can i ask what is the method replacing "map.addOverlay(layer)" in version 3. i have try using custom overlay function, but is comes out as a image which doesn't match the result i want.
** take note : ArcGISDynamicMapServiceLayer is to call a time aware data layer from esri
Have a look at these examples:
http://gmaps-utility-gis.googlecode.com/svn/trunk/arcgislink/docs/examples.html

how can update to google map api version 3 in drupal 6

In my drupal site, I have installed the gmap module. But that is in version 2.115. Now I got a mail from google that update the google API version. I have generated the API key version 3. But no idea about implementing them to the module files.
drupal_set_html_head(' $query))) .'" type="text/javascript">');
This I changed to
drupal_set_html_head('');
Also in gmap.js
obj.map = new GMap2(elem, obj.opts); changed to obj.map = new google.maps.Map(elem, obj.opts);
But after adding this, Javascript is required to view this map. is showing.
Please help me
See this thread on d.org. There are several patches and solutions.
