Unable to contact server?

Question

I've download the new Bing Maps WPF control, imported dll, use excatly the same code with the Documention, keep getting this error: "Unable to contact server. Please try again later"

XAML:

 

<Window x:Class="Weather.MainWindow"
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
  xmlns:m="clr-namespace:Microsoft.Maps.MapControl.WPF;assembly=Microsoft.Maps.MapControl.WPF"
  Title="MainWindow" Height="1080" Width="1920" ResizeMode="NoResize" WindowStartupLocation="CenterScreen" WindowState="Maximized" WindowStyle="None">
 <Grid>
  <m:Map Mode="AerialWithLabels" CredentialsProvider="CODE" x:Name="myMap" Center="37.806029,-122.407007" ZoomLevel="10"/>
 </Grid>
</Window>

I also disabled "Use Http1.1 option and UseHttp1.1 through a proxy connection within IE's advance options", it didn't work either.

 

Any idea to fix this?

Thanks in advance.

Answer 1

This message is displayed, when the map is not able to reach to config file for initialization of map resources.

Try changing the proxy settings & make sure program can access internet.

It has access to internet. How can I change the proxy settings? From Project Properties?

Thanks

I set the app.config like this:

<?xml version="1.0"?>
<configuration>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0" />
  </startup>
  <connectionStrings>
    <add name="DefaultConnection" connectionString="Data Source = |SQL/CE|" />
  </connectionStrings>
  <system.net>
    <defaultProxy useDefaultCredentials="true" />     
  </system.net>
</configuration>

I still get exactly the same error with the link you mentioned. Please check the image below for more details

Answer 5

Hello Did you get the solution for the above error. Please reply

Answer 6

I haven't got a solution for that yet but I figured out what causes the problem. Map control doesn't like to work behind a firewall. I do not get any error at home since there is no firewall but at work i keep getting the error. I tried opening all of the ports and ips for my IP number, nothing happened then I completely disabled firewall, it works fine now, so the solution is easy; disable the firewall :)

Answer 7

I figured the problem. We need to set the proxy setting if it doesnt like the fire wall.

 System.Net.WebRequest.DefaultWebProxy = new WebProxy("<Proxy Address>", 80);

            System.Net.WebRequest.DefaultWebProxy.Credentials = new NetworkCredential(<UserID>,<PassWord>);

 

If you set the default web proxy it Bing Maps will use it.

 

Hope this helps everyone.

Answer 8

Sandeep,

I doesn't work for me, I still have to disable the firewall.

Thanks

Answer 9

This doesn't work for me, either.  There doesn't appear to be any way to get the control to use the proxy.

Answer 10

I'm new to WPF, but I added an app config file to my wpf project and there is a warning marker on that files' icon in the solution explorer. Plus I added the configuration settings recommended by Hement and still not able to get map to appear. I am behind a firewall and have no option to turn it off.

Sandeep: where does your code go? Should I use it in addition to Hements configuration settings?
