It may close this topic. I've got comrehensive answer from Mr.Holmes.

If you're interested in. This is answer: It represents the number of milliseconds the system takes to complete the processing loop from the VM.

No, it is just the number of milliseconds between the timer starting, and the Elapsed event being fired. This will occur after approximately 250 milliseconds as declared by the timer intialisation values.

There appear to be a couple of structural issues with this code. The first thing is, you haven't shown us the complete class. Secondly, you update _lastScanTime to a different DateTime.Now than when you update ScanTime - in a multi-threaded application, this could be a potentially significant difference because of your ValuesRefreshed. To be honest, I don't know why you don't make ScanTime raise INotifyPropertyChanged.PropertyChanged and avoid other events; you can bind directly to that value. Also, I would use a StopWatch instead of DateTime.Now if I were you.

Simpliest code: Can't change label "Content" programmatically

Hello everyone.

Currently I am trying to work with timers in WPF.

private void Window_Loaded(object sender, RoutedEventArgs e)
       {
           _timer = new System.Timers.Timer();
           _timer.Interval = 1000;
           _timer.Elapsed += OnTimerElapsed;
           _timer.Start();

       }

       int i=0;
       private void OnTimerElapsed(object sender, ElapsedEventArgs e)
       {
           i++;

           label1.Content = i.ToString();

       }

I've got an exception at this string

label1.Content = i.ToString();

What I'm doing wrong with a label?

Thanks in advance!

XAML:

<Label x:Name="label1"  HorizontalAlignment="Center" Margin="2" VerticalAlignment="Center" Height="79" Width="86"/>

You access it from a different thread - you must not do that, and that holds true also for other UI technologies like WinForms.
With WPF also comes MVVM. Instead of setting the Content property directly, you bind it to some property of your view model. When that property changes, you raise an PropertyChanged event, and that will do the magic of "transporting" the change in the correct thread.

Please explain where have you seen " different thread"?
"different thread", you mean that with a System.Timer it's not possible?

P.S. Here https://www.youtube.com/watch?v=QkT8fgoFz3g, a guy is doing that easily. True he's using a Dispatcher Timer. So what's difference?

The DispatcherTimer documentation makes things slightly clearer than the System.Timers.Timer documentation:

DispatcherTimer Class (System.Windows.Threading) | Microsoft Docs[^]:
If a System.Timers.Timer is used in a WPF application, it is worth noting that the System.Timers.Timer runs on a different thread than the user interface (UI) thread. In order to access objects on the user interface (UI) thread, it is necessary to post the operation onto the Dispatcher of the user interface (UI) thread using Invoke or BeginInvoke.

Reasons for using a DispatcherTimer as opposed to a System.Timers.Timer are that the DispatcherTimer runs on the same thread as the Dispatcher and a DispatcherPriority can be set on the DispatcherTimer.

No.
It doesn't quite work like that.
We do not do your work for you.
If you want someone to write your code, you have to pay - I suggest you go to Freelancer.com and ask there.

But be aware: you get what you pay for. Pay peanuts, get monkeys.

The idea of "development" is as the word suggests: "The systematic use of scientific and technical knowledge to meet specific objectives or requirements." BusinessDictionary.com[^]
That's not the same thing as "have a quick google and give up if I can't find exactly the right code".
So either pay someone to do it, or learn how to write it yourself. We aren't here to do it for you.

Talk of money? If I were Moderator I would ban such posts (where there are talks of money). Because it is a sure sign of soon dying of the resource.

PostScriptum: One of the principles of Free Internet sounds right about "peanuts and useful monkeys". Otherwise, a resource will die.

Hope this helps.

That's a mistake in the text of the sample you're following. The {StaticResource ...} key needs to match the <Style x:Key="..." key. Change the window style to:

Perhaps if you tell us what problems you're having - the full details of the error, and the line it occurs on - then someone might be able to help you.

Otherwise, you might want to take a look at a MahApps.Metro[^], which provides a relatively easy way to customize your WPF windows.

Avoid layout out controls using margins, and avoid specifying a width and height for controls that don't need them.

For basic layout, use one of the standard layout panels, and use the horizontal and vertical layout properties to position your controls.

If you're creating a drawing, it's usually better to use the Canvas, and set the Canvas.Left and Canvas.Top positions instead.

If you want the drawing to resize with the container, you'll probably want a Viewbox as well.

Eg:

XML

<Grid ShowGridLines="True">
    <Grid.RowDefinitions>
        <RowDefinition Height="80"/>
        <RowDefinition Height="1*"/>
        <RowDefinition Height="160"/>
    </Grid.RowDefinitions>

    <Canvas Grid.Row="1" HorizontalAlignment="Center" Width="1024" ClipToBounds="True">
        <!-- NB: No "Grid.Row" on the children; Margin replaced with Canvas.Left and Canvas.Top: -->
        <Path Data="M319.5,255.83333 L511.5,255.47633" Fill="#FFF4F4F5" HorizontalAlignment="Left" Height="1.357" Canvas.Left="255.468" Canvas.Top="175.5" Stretch="Fill" Stroke="Black" VerticalAlignment="Top" Width="193"/>
        ...
        <TextBlock x:Name="textBlock2" HorizontalAlignment="Left" Canvas.Left="387.968" Canvas.Top="10" Grid.Row="1" TextWrapping="Wrap" Text="Center vert. line of the 1024x768 screen" VerticalAlignment="Top"/>
    </Canvas>

    <!-- NB: No Margin, Width or Height; use horizontal and vertical alignment instead: -->
    <TextBlock x:Name="textBlock1" HorizontalAlignment="Center" TextWrapping="Wrap" Text="I need that Row" VerticalAlignment="Center" FontSize="24" TextAlignment="Center"/>
    <TextBlock x:Name="textBlock1_Copy" HorizontalAlignment="Center" TextWrapping="Wrap" Text="I need that Row" VerticalAlignment="Center" FontSize="24" TextAlignment="Center" Grid.Row="2"/>
</Grid>

With a Viewbox:

XML

<Viewbox Grid.Row="1" HorizontalAlignment="Center" Stretch="Uniform" StretchDirection="Both">
    <Canvas Width="1024" Height="400">
        ...
    </Canvas>
</Viewbox>

(You'll probably need to play around with the canvas's height to get the result you want.)

Hello Richard,
first of all thank you for replying. Currently doing comprehensive test of the first variant (with Canvas).
Please share with experience; how to move eg. my sketch, if it's situated within Canvas space.
I asked because I'd failed to move the sketch separately (it moves with Canvas itself only).

Thanks in advance!

P.S. the first feeling. It seems Canvas' variant strongly keeps original (1024x768) position of the controls. With no adaptation/resizing, though. In other words the controls don't "swim", at least. Thumbs Up | :thumbsup:

To be continued.

Yes, it seems that's it! The ViewBox's variant, in contrast with Canvas' variant, strongly keeps position of the controls and scales them correspondingly to given aspect ratio/resolution. Thumbs Up | :thumbsup:

To be honest, I tried to use symbiosis of Canvas and ViewBox; true, with no success. Because I didn't use some significant (as it turned out) parameters which you offered.

P.P.S. Previously, I asked the same question at many places. I got a strong sense that nobody had got me. What I really need. I provided the same sample code, though. As though the people never faced with such kind of issues. Perhaps they don't port their apps to another workstations or make "Calculator" apps only, or so. Confused | :confused:

my regards.
