I have a problem where I run my program and it gives me a STA Error on my "Test" Window. It does not have an error if I don't have a timer going from the Page I am running till the window. I'll show and Example:
public Page1()
{
InitializeComponent();
Task.Delay(2000).ContinueWith(_ =>
{
var page = new TestW();
page.Show();
}
);
}
This is from my Page1 to open up my TestW ( Test Window )
My main code looks like this:
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void Luk_Click(object sender, RoutedEventArgs e)
{
Close();
}
private void Button_Click(object sender, RoutedEventArgs e) // Login
{
Main.Content = new Page1();
Framep.Visibility = Visibility.Visible;
GridS.Visibility = Visibility.Hidden;
}
}
And my XAML Code:

The problem I have: If I run with the Task Delay My test Window gets an STA Error that I don't know how to fix.
If I run without the Task Delay It just opens it all up but no STA Error.
I am trying to do this:
When I press on the Login button It is supposed to open the Page1 and hide the main window for a " Loading " Screen and then after the delay to close Main window + Page1 down to Open up the New Window. Been sitting with this for a little while :) Thanks in advance!
-- Test Window Is plain. No code there.
This is the Background.
The problem is that the Action given to ContinueWith will not be exectued on the UiThread but on a free ThreadPool-Thread, so the new TestW object will be constructed and used by a non STA-Thread. But any WPF-UI-component must be constructed and used by an STA-Thread.
The solution is to replace your Task.Delay() with
Task.Delay(2000).ContinueWith(_ =>
{
Dispatcher.Invoke(() =>
{
var page = new TestW();
page.Show();
});
});
This will delegate your execution back to the UiThread.

I am trying to learn c# and WPF application. Here I am trying to redirect from one WPF page(MainWindow.xaml) to another(HandWash.xaml) on a button click event. But the following code is throwing NULLReferenceException.

navService.Navigate(teeth); // NULL REFERENCE EXCEPTION at this line
}
catch (NullReferenceException ex)
{
System.Windows.MessageBox.Show(ex.Message);
}
}
This is the code for TeethBrush.xaml :

</Page.Background>
</Page>
and the background code is:
public TeethBrush(Myargs arg)
{
InitializeComponent();
//Rest of the code
}
Please help....
You need to have a frame in main window where contents of Pages will be hosted.
If you add the following namespace to MainWindow:
xmlns:local="clr-namespace:System.Windows.Controls;assembly=PresentationFramework"
you can define a frame somewhere, e.g. in your grid:
<Grid>
<local:Frame x:Name="mainFrame">
</local:Frame>
....
Then you can navigate from your event handler like so:
TeethBrush teeth = new TeethBrush(myarg);
this.mainFrame.Navigate(teeth);

}
private void Contactos_Btn1_Click(object sender, RoutedEventArgs e)
{
}
}
when i try to run my project, it loads the map but a few moments later i get this exception
"Additional information: Value does not fall within the expected range."
when i do the "contactosMaps.Layers.Add(pinLayer);"
can't i have that Grid with the image as a pushpin?
Use the Phone.Controls.Toolkit as described here:-
http://wp.qmatteoq.com/maps-in-windows-phone-8-and-phone-toolkit-a-winning-team-part-1/
The toolkit can be found at either of
http://phone.codeplex.com/
or
https://www.nuget.org/packages/WPtoolkit
You can then either add the image directly in your XAML as follows:-
<maps:Map Loaded="MapControl_Loaded" ZoomLevel="18" Name="MapControl">
<toolkit:MapExtensions.Children>
<toolkit:Pushpin x:Name="MyPushpin">
<toolkit:Pushpin.Template>
<ControlTemplate TargetType="toolkit:Pushpin">
<StackPanel>
<Image Source="/Images/MapScreen/MapScreenCurrentLocationPin.png" Stretch="Uniform" Width="50" Height="50" HorizontalAlignment="Center"/>
</StackPanel>
</ControlTemplate>
</toolkit:Pushpin.Template>
</toolkit:Pushpin>
</toolkit:MapExtensions.Children>
</maps:Map>
or you can add it in C# as follows:-
MapOverlay overlay = new MapOverlay
{
GeoCoordinate = myMap.Center,
Content = new Ellipse
{
Fill = new SolidColorBrush(Colors.Red),
Width = 40,
Height = 40
}
};
MapLayer layer = new MapLayer();
layer.Add(overlay);
myMap.Layers.Add(layer);
You should be able to add a Grid with an image instead of an ellipse as shown above.
Let me know if this worked for you.
I am trying to create my first Windows phone application but I keep getting this "XamlParseException" thrown at me.It looks like the error is coming from the InitializeComponent() method which is a shock because it was automatically created by VS.

The program has only 3 elements, 1) A TextBox 2) A TextBlock and a 3) Button. The user inputs data into the textBox then clicks a "Go" button, if the input is "1 2 3 4" the app will display "You have Won" in the textBlock, if any other input has been entered it will display " You have lost".Please Help, I do not know any Xaml so I can't play around with the Xaml code.
Change the parameter e in your PhoneApplicationPage_Loaded to an instance of the RoutedEventArgs class:
private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e)
{
myTextBox.Focus();
}
Your error is due to PhoneApplicationPage_Loaded event handler method. It should be like this:
private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e)
{
myTextBox.Focus();
}
