WP8 - How to disable the app Splash Screen for certain pages? - c#

I have an app that uses a Splash Screen when it opens up, and it works fine.
The problem is that I've added a couple of pages that can be accessed via two live tiles, and the point is to let the user istantly load a certain section of the app without having to load the whole MainPage.xaml page, which is quite heavy to load.
These two pages are really simple and load almost istantly, but the app loads the Splash Screen anyways, and I don't like that.
Is there a way to "disable" the splash screen for a specific page?
Via C# or directly from the XAML, I don't know.
I enabled the Splash Screens simply by adding the SplashScreenImage.screen-WXGA.jpg (720p and 1080p as well) to the project main directory.
Thanks! :)

No. You can't disable the splash screen. What you can do is to minimize all initialization work your app has to do so that the splash screen is shown for a minimum of time.

Sergio,
You can simulate a splash screen and decide based on how you were activated to show it or not. This sample shows one way to do it: https://code.msdn.microsoft.com/windowsapps/Splash-screen-sample-89c1dc78/
I would show it for the main xaml and others that take a long time to load and dismiss it in code.

Update UI when application runs in backroud

I am developing a banking application for Windows Phone 8.1 RT. For security reason I need to grey out or show an image in my application when it goes background.
It's like when application is running user presses windows button then press and hold back button at that time application's current page is visible. I need to show a image on that view.
When application is running if user press and hold back button at that time also irrespective of page I need to grey my application or show an image.
I have tried changing the opacity of frame in On suspending event it is not reflecting. I have also tried in Window visibility changed event changing the opacity of Window.Content but it's not working too.
Please help me with some pointers on how to achieve this.
There isn't a good way to do this. The app doesn't suspend until several seconds after it has left the screen, so it is too late for the app to change its UI then. Window.Activated would be closer, but is still too late.
ApplicationView.IsScreenCaptureEnabled will prevent capturing a screenshot of the page either in the app or on the task switcher page, but won't prevent the image from showing at all.
The least bad may be to call Application.Current.Exit to close the application completely when deactivated. This is generally a user unfriendly idea, but it will remove the app from the task switcher one it closes (it will probably show up briefly first though).

App that is not showing on projector

Is there a way to create an app on .NET that will be used when connected with projector/external PC but will be shown only on main screen?
Thanks.
I don't think this is possible. Powerpoint has the functionality of showing notes just on the primary display. But this is only possible when the desktop gets extended and not mirrored to the beamer.
So you shold have to extend the desktop to the beamer and then place the App window on the main screen manually.
System.Windows.Forms.Screen.AllScreens gives you access to monitor information in C#. The PrimaryScreen Property tells you, which screen is the main Screen. You may move the window from one screen to another by respecting the screen widths.

Can I use the splashScreenImage to all my app pages?

I'm writing an application for wp7 with several pages, and i want to the splash screen image at the load of every page i have in the app - so the user would figure out he needs to wait a few seconds.
The default splash screen image is fine for me, but i don't know how to do it.
thanks for any help!
You can customize your own splashscreen dont need to use the default
Use the Loading method for the page which should be located on a panel on the left side of Visual Studio's Screen
You can do this by loading the SplashScreen Image on load of every page for some predefined time. And meanwhile other tasks can be done on Background threads (if they are not related to UI).
Also if you want to show a loader to User, you can create a Grid with some Background (semi transparent) and a Progress Bar on it. You can set its Visisbility true before any process which will take time and then hide it after process ends and Application is ready for user..

How do I use a window as splash screen in WPF?

I would like to use a regular window for splash screen, so no PNG splash screen but a normal window where I can add some bitmaps on.
What is the best way: to keep in app.xaml the loading of the main screen and put the splash screen in the constructor or somewhere in an event handler?
The splash scren itself is quite easy, just has some labels, a link, a few images and just waits a few seconds before closing, no actions to be done while waiting.
Specifically for a splash screen, it is very important to make use of the functionality introduced in .NET 3.5 for this purpose. If you simply use a vanilla Window it can take quite some time for the WPF stack to initialize, and in the interim the user will not be seeing any feedback for their "launch the app" action.
Of course this does not satisfy the requirements of the question ("use a regular window"), but if it's not acceptable I would recommend using an different technology than WPF entirely because of the problem mentioned above.
I have myself designed my WPF app dynamic splash screen in which there was an animation, dynamic software Number which changed for each and every software, a label which was updated every 1/2 ms to show some random filename in the sofware directory.

C#: What is the ideal method of adding a splash screen to a project?

I'm going to input a splash screen to an application I'm currently working on that only consists of one form which we will call frmMain for now. I want to implement a splash screen (frmSplash) but need advice as to what would be the best way to implement it. The purpose of the splash screen will be to load necessary settings into textboxes, checkboxes, etc. based on the last settings of when the program was last closed. Here's my question.
Should I let the main form load, but keep it invisible to the user and then call the splash screen which will run and then load all the settings into the main form?
If so how would I do the above? Load the frmSplash in the frmMain_Load event? I plan to keep the splash screen visible for at least 3 seconds. How would I give it the pause effect so that it stays up for 3 seconds while it recovers the settings from the settings file?
Yes, it is a good practice to use a splash screen to hide form initialization. Here is a pretty good tutorial that should get you up and running:
Creating a Splash Screen in C#
It's probably cleaner not to load the settings in the splash form, but to keep that just for display. Display the splash form and load the settings in the main form.
I would suggest going the other way. Have frmSplash start up, parse the settings and pass them on to a new hidden frmMain. And once frmMain has finished loading (or after 3 seconds) show it.
Or just have the splash screen create a hidden frmMain and show it once it's done loading and in a valid state.
There's an example here, and one with better explanations here.
Note that neither of these examples perform any kind of "pre-loading", but you can do all that in the main thread while the splash thread is doing its eye-candy work.
Hopefully this is the kind of thing you're looking for. Good luck!
Here's a canned version you can try: Autorun Action Splash
