Creating a marquee lookalike in Windows Store Apps - c#

im trying to create the equivalent of this(html)
<marquee behavior="alternate">Your bouncing text goes here</marquee>
in a Windows Store App, with C#
is there any control that can do this or do i have to create a custom one?

There are no Marquee controls in Windows Store Apps.
I have managed to find code doing something similar to what you are trying to do. Go take a look at WPF Marquee Text Animation. If you play around with that code you should be able to get the wanted result
The main difference with your Marquee is that once you reach the edge of the screen you want to go back the other way. Something as simple as getting the Width of your textblock and your grid and substracting them could give you the wanted result
One way to do it would be something like this :
Get the width difference of your controls
int TotalMargin = gridTest.Width - textblocktest.Width
You would then need to add continuously a value to your margin
if textblocktest.Margin.Left < TotalMargin {
textBlock.Margin = New Thickness(textblock.Margin.Left + aNumber,0,0,0)
}
else{
//Call a procedure doing the same thing but decrementing the margin until it is at 0 and then going back to adding margin
}

How to align one line in a textbox c#

I'm trying to make a calculator where the result of the calculation should display on the right side instead of the left.
Unfortunately, you can't use tbx_main.TextAlign = HorizontalAlignment.Right; since it makes the whole text align on the right. It would really be useful if there was a way like \t where that row only gets dragged to the right. I'm unsure if there even is a solution to this...
you can use TextBox.TextAlign Property if you are are using Windows Forms

for WPF

How to properly resize app to visible bounds on UWP? (VisibleBoundsMode doesn't seem to work)

I have two UWP apps and after testing them out with Continuum I noticed the app bar of the OS (the bar with the Start button) at the bottom of the screen (it can be at each of the 4 edges of the screen, of course) was covering part of my app.
Now, I'm already using ApplicationView.GetForCurrentView().SetDesiredBoundsMode(ApplicationViewBoundsMode.UseVisible) before calling Window.Current.Activate(), but that doesn't seem to solve the issue.
1) Why is it that setting the DesiredBoundsMode property doesn't seem to work here? Shouldn't that automatically resize the window
content to the visible bounds (ie. excluding system overlays like the
navigation bar or the app bar)?
The workaround I'm using for now on Windows 10 Mobile devices is to subscribe to the VisibleBoundsChanged event and then manually adjust the margins of my Window.Current.Content item to make sure it doesn't show anything behind covered areas of the screen.
Basically, I use the Window.Current.Bounds property and the ApplicationView.VisibleBounds property to calculate the occluded areas on the different edges of the app window, and increase the margins from there.
2) Is there a proper/better way to do this?
I mean, I'm quite sure there's another method that should be used to avoid this issue (considering there are tons of different situations like Continuum, navigation bar etc... that I don't think are supposed to be manually handled one by one).
Thank you for your help!
Use the subscription to the event VisibleBoundsChanged. This is the best solution that I found.
var curr = ApplicationView.GetForCurrentView();
if (curr.IsFullScreenMode == true)
{
ApplicationView.PreferredLaunchWindowingMode = ApplicationViewWindowingMode.FullScreen;
curr.FullScreenSystemOverlayMode = FullScreenSystemOverlayMode.Minimal;
}
else
{
ApplicationView.PreferredLaunchWindowingMode = ApplicationViewWindowingMode.Auto;
curr.FullScreenSystemOverlayMode = FullScreenSystemOverlayMode.Standard;
}

How to align windows when they are very near

I have an application with some small windows on the screen. I would like to align them to each other, so when I move one close enough, it will automatically be align with the other. Helping me positioning and size them all.
How can I know the position of other windows when there isn't a parent window? Is it possible to know it even if they are different process (applications)?
I am not fully sure what you mean but the following trick is what I use for dynamic layout and it gives me full control over anything, you just need to play around with it and you can easily get the distance between two windows.
This code is copied from a windows phone app but it is easily understood.
width = Convert.ToInt32(Window.Current.Bounds.Width);//gets window width
height = Convert.ToInt32(Window.Current.Bounds.Height);// gets window height
double dist Math.Abs(Btn1.GetValue(Canvas.LeftProperty) - Btn2.GetValue(Canvas.LeftProperty) + Btn2.Width);
note first two lines are only in order to have the proportions right in every single movement and resize you do, you can keep it all proportional to the window size.

maintain button's position in c#, no matter the resolution of the screen

i designed a game in c# and finished it... but i tried it on my friend's laptop with different screen size and resolution, all my design was in a total mess!!
if there is a way to keep everything (panels, picturebox,buttons,labels,...) in their positions despite the size and resolution of screen!?!?
really need help, my project's deadline is on Monday :(
Use anchors on your controls:
I assume this is a windows form application? If so, you can use docking to maintain positions. Also, the positions should stay the same anyway unless the form is not a fixed size.
So use docking or a fixed sized form.
Also, please make sure to specify what type of GUI framework you're using next time. My answer is incredibly wrong if you're using something other than windows forms.
Aside from docking, another option would be to place all of your objects within a panel, and then center it horizontally and vertically on your resize event. e.g.
panel1.Left = this.Width/2 + panel1.Width/2;
panel1.Top = this.Height/2 + panel1.Height/2;
This will ensure that your applications static contents are always centered, regardless of resolution.

Showing image / text on screen without forms in c#

How can I show something on screen wihtout using forms?
Actually, I want to show some text and images popping on screen.
EDIT: just like i said HERE
What you can do is to create a alphatransparent form that draws the PNG and position it at the correct location and bind move etc.
http://www.codeproject.com/KB/GDI-plus/perpxalpha_sharp.aspx
PerPixelAlphaForm transparentImageForm = new PerPixelAlphaForm();
transparentImageForm.SetBitmap(<IMAGE GOES HERE>,<OPACITY GOES HERE>);
//opacity is the opacity that the image will be drawn with, a value of 255 = all transparent parts will be alpha/transparent just as much as the original PNG etc..
and you can put a timer that calls SetBitmap and changes the Opacity to fade in/out the image on the screen
And you can generate the text (on the fly) in a nice way with code from THIS article
and pass that image to the SetBitmap of the AlphaTransparent form.
EDIT: OR GO TO WPF.
I don't think you can: a form is equivalent to a window, and Windows applications draw into a window and not directly onto the screen (unless perhaps it's the backgroun/wallpaper, which I don't know about).
I think that's overdoing it but XNA will allow you to draw to the screen, but it is meant to be used for games so you will have trouble fitting it to a normal application.
