Remove black screen upon application launch - c#

I have created a C# WPF application. In that i have limited UI components (label, MediaElement, Image sources(4)). I am loading my application with maximized window.
When I launch my exe, a Black screen is shown for a second and the actual UI appears.
I set one property i.e., AllowsTranparency = True. It solves the above problem but on cost of a new one i.e., If this property is set to true, the Video played in MediaElement lags a lot.
So, this solution is ruled out.

I want to remove the Black screen that comes on launch of the application.


Change the Background="Color you want" or Transparent of Window tag.

WPF White screen and 1 GB of umanaged RAM usage on Windows 8.1 and Windows 7

I have a problem with WPF Application. It runs perfectly on Windows 10, tested on latest update 1803 and latest Insider Fast, but when application is run on Windows 8 or 7, application starts, uses 1 GB of unamanged RAM for few milliseconds and then renders only white screen. App is running and I can see cursor changing and code running in background, but when I try to move Window for example, application crashes with Out Of Memory exception and Application does not have enough memory to execute.
I do not understand this problem, I tried removing code from it... It can be libraries or XAML.
I tried different .NET versions. I am out of ideas.
Did anyone ever had this problem? How to solve it? I can publish code if required to get help... I am really lost.

You must have set these two properties to your Window:
window.AllowsTransparency = true;
window.WindowStyle = WindowStyle.None;
This two properties will change your window into a layered window and will take much more memory than a normal one.
If you have done so, remove it. If you want a custom title bar, try to use a WindowChrome.

WPF & C# [Mahapps.Metro] Animating Controls

I'm starting to learn a little bit of WPF and Mahapps.metro, so I'm pretty new with those ones; here the question:
I have a button and two textboxes, the textboxes visibility is hidden when the forms loads, so when the user clicks the button, the textboxes visibility will be visible, but I want the textboxes to appear with that "slide" animation of the form load that Mahapps provides with the MetroWindow.
I tried using TransitioningContentControl but I couldn't make it happen. I would really appreciate your help, thanks.
My XAML:

EDIT: This method gave me the solution, the only difference is that the control that I used was ContentControl instead of StackPanel, here is my xaml for anyone who wants to make something like this:

Example

You didn't place any content inside the transitioning content control. Try this:
<Grid>
<Button x:Name="button" Content="Button" HorizontalAlignment="Left" Margin="238,89,0,0" VerticalAlignment="Top" Width="75" Click="button_Click"/>
<Controls:TransitioningContentControl x:Name="transitioning" Transition="Down">
<StackPanel>
<TextBox x:Name="textBox1" HorizontalAlignment="Left" Height="95" Margin="345,51,0,0" TextWrapping="Wrap" AcceptsReturn="True" VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Disabled" VerticalAlignment="Top" Width="211" Controls:TextBoxHelper.Watermark="Hi Im a watermark" Background="#FF7400FF"/>
<TextBox x:Name="textBox2" HorizontalAlignment="Left" Height="95" Margin="0,51,0,0" TextWrapping="Wrap" AcceptsReturn="True" VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Disabled" VerticalAlignment="Top" Width="211" Controls:TextBoxHelper.Watermark="Hi im another watermark" Background="#FF7400FF"/>
</StackPanel>
</Controls:TransitioningContentControl>
</Grid>
Plus, reading the documentation, you'll see TransitioningContentControl performs the animation when the content changes. So you want to start with empty Transitioning Content Control, and then inside your Button click handler, set TransitioningContentControl Content dynamically to the two textboxes (need to be wrapped inside another control, like StackPanel, because transitioning control can only have a single child content.

Animations in WPF are quite tricky to pull of. I've made a fade animation a while back and it was quite a lot of work. Such a slide animation would require a lot of code and debugging to get it right. My recommendation is use a free slide animation library, and if you are feeling up to the task, you might be able to get a hold of some source code that you can use for inspiration if you want.

Need images with lower resolution "stretched" to screen size

I am making a video game using C# WPF.
What I am trying to implement now, is to add additional resolutions.
My default monitor resolution is 1600x900.
I am using the same size for game's window and grids.
Now, I want to add more resolutions. I already found an easy way to change values in code, the problem is on another topic.
That's how the game looks on 1600x900.
Then, I am trying to set resolution 800x600.
What I want to achieve, is to make images with resolution lower then the one set in Windows, to get "stretched" and still cover the all screen.
That's what I get. The game only takes a part of the screen, and white background on the remaining part.
The stretched window, what I am trying to achieve looks like that. To create this image I stretched the previous image in graphics editor. I want the game do it by itself.
If you look at first and third screens at full size, you'll notice they are different, and that lower image has worse detail.
How can the window or grid has resolution lower that one in Windows, but still cover full screen?
UPDATE: Code for one of game screens - the main menu

Thank you,

Just remove the HorizontalAlignment="Left" Height="600" VerticalAlignment="Top" Width="800" from your grid so that grid can stretch to the whole window,
if you need these values use it on the window itself
Edit:
Okay, I see that you're setting the height and width for each element(like the buttons) inside the grid , and you're setting the margin to move them to the correct place,
This will not work with different resolutions. lets say you set the window width to 800 and your button is set to be 200. if you change the window width to 1024, this change will not be reflected automatically to the buttons, it will always be 200 (and same goes for the margin)
The correct solution is to rewrite the xaml code in the correct way, (you will use Grids with Grid.ColumnsDefinition/RowDefinition, Stackpanels ..etc) without setting the values in pixels.
But if you're in hurry you can put all elements in a Viewbox:
<Window ....
<Viewbox Stretch="Fill">
<Grid x:Name="areaContainer" ....
</Grid>
</Viewbox>
</Window>
Now note that using viewbox will stretch your content based on the Viewbox's width and height (so its like what you did in the graphics editor).
Also note that Viewbox should be avoided as it's very expensive in terms of resources

Silverlight 4 app, controls disappeared?

Trying to figure out why my silverlight app suddenly just displays nothing (right click shows silverlight) when i run it and also nothing when i open the html-document created by VS2010?
This happened all of a sudden and i have no idea why. I have even deleted all my code behind except for an event.
Silverlight code:
<UserControl x:Class="Test.MainPage"

</Grid>
</UserControl>
Code behind:
public partial class MainPage : UserControl
{
public MainPage()
{
InitializeComponent();
}
private void button2_Click(object sender, RoutedEventArgs e)
{
}
}

Resolved after deleting all contents and recreating them again. Very strange behaviour.
