I may not be explaining myself the best with the question, I'm usually bad at that. But I'll try my best.
This to me seems like something that would be fairly simple, I'm builing a program in Visual Basic and it has a Splash Screen. While I like the clean splash screen, some users might not and I want to give them a simple way to disable it using a defined setting in the program.
This setting when false would disable the splash screen, when true the splash screen would show up (default).
The easiest way to do this is either on the splash screen itself, on the bottom left or right, put a checkbox that says "Don't show again" and if they check it, save the setting and next time you load the application check that and decide accordingly. Or alternatively, you can put it under the settings/options of the application too. Some do it in both areas to ensure that if the user ever wants it back, they can get it without manually editing the setting for it. Any further suggestions or examples, let me know and I can whip something up for you but this should be pretty self explanatory.

I want to write a program that creates cool effects in VB.NET.
Few example of what the program should do:
How to make an intro to my program? I know how to make a splash form but can I put an animated logo?
I want to put effects to buttons, such as the effects in the (HTML-CSS) websites, and also in the professional programs.
Finally , Can I make notification-icon (Tool-Tip), like Avast 2015 ? > http://imgur.com/65DbXoN
You might be able to modify a splash screen for an animated logo. Try using a picture box with a logo picture in a .gif format. However I've never tried that before.(Worth a shot tho)
For button effects there are many ways to do it. You can add sounds, add pictures/icons,ect.
I've never done much with tool tips before, however they can be done. To make them look like the image you provided, I don't think would be easy.
I have to display a popup for a legend like in STMS transaction
I know how to write this tab with WRITE statement, but how can I display it in a popup?
You can achieve this by using CALL SCREEN ... STARTING AT ..., then using SUPPRESS DIALOG in the PBO processing to bypass the screen (dynpro) processor. Then, in the PAI processing, use LEAVE TO LIST-PROCESSING followed by the WRITE statements. You can follow this in the function module TMS_UI_POPUP_LEGENDE that shows the popup you mentioned as a reference. The procedure is documented in the online help as well.
In an ABAP dialog application, you're either working with screens or with (interactive) lists. To get a popup window, you have to create and CALL a custom screen (dynpro). Inside that screen, you hand over control to the list processor. That's the component responsible for taking what ever you WRITE and place it somewhere on the screen. For some - probably mostly historical - reason, the command to do so is LEAVE TO LIST-PROCESSING. I suppose that at some point, the intended flow between screens and lists was different from what it has become today, and that was the reason for naming the command this way. From a modern point of view and especially in your use case, the LEAVE aspect does not make any sense, so just take it as it is and use it.
Also note that it's LEAVETOLIST PROCESSING - LEAVE LIST-PROCESSING without TO is the opposite statement!
I would like the user to be able to click on the system tray icon to hide a window if it is visible, or show it if it isn't. However I can't see way to detect the show/hide state of the window.
I looked here but couldn't see anything that would give me what I need. The only way seems to be to keep track of if my last call was to show() or to hide(). Is there a better way?
I've needed this myself just recently, but as far as I know the best (only?) way is to set a boolean (e.g. var showing = true;) and then on every change (including the minimize and restore events) set the boolean to the correct value. Then you could simply make an if statement when clicking on the tray icon to see if the window is showing, and if it is hide the window, otherwise show it.
Hope I helped you a bit, I'm still looking for a better way myself but this is all I have found so far.
I am developing an app that allows the user to make certain changes to tiles on the Windows 8 start screen. When a change has been made within the app, the user will be shown a "View my changes" button. Clicking the button should bring the user back to the start screen.
I have looked into different ways of closing/suspending the app programmatically (and thus taking the user to the start screen), but I have not found a way to achieve this using WinJS. Throwing an exception closes the app, but this seems like a very dirty workaround. Any suggestions?
I'm assuming you are creating secondary tiles and want to show the users what they look like? #mydogisbox is right in that this kind of functionality has probably been deliberatly excluded.
I'd recommend to just do an in-app 'view changes' of whatever changes to secondary tiles the user might have made. In general, I'd argue that this would be a better user experience because you will keep the user engaged within your application and not be essentially kicking them out of the experience.
How would I go about locking a screen like Keychain does, meaning preventing all access to Dock, menubar, desktop, etc. Basically just a black screen that I can add a password field to, for the user to return to the desktop? I am well aware of the Carbon method, but I want the NSApplication method because this is an all Cocoa application.
Thanks~
If you can get away with not writing this code yourself, all for the better. It is usually a terrible idea to write your own code to lock the screen, considering the number of vulnerabilities that have been found in screen locking code over the years. If you have a Carbon call that can do it, go ahead and use that... don't worry about the "purity" of your Cocoa code.
However, if you decide to write this yourself, here's what you do:
First, capture all the screens using CoreGraphics. See: http://developer.apple.com/mac/library/documentation/GraphicsImaging/Conceptual/QuartzDisplayServicesConceptual/Articles/DisplayCapture.html
Next, create a new NSWindow and put it in front of the window that's used for capturing the screens. You'll have to call a CG function to get the "order" of the black window covering each screen, and order the new window in front of that. Normally, the black window has an order so far forward that everything is behind it. Put a password field in the window. Do NOT use an ordinary text field or write your own code for password input. The password input field has a ton of special code in it so you can't copy text out of it, and other programs can't listen to keystrokes while you're typing into a password field. So use the one that Apple provides.
Last, put the computer in "kiosk mode". This mode allows you to disable alt-tab, user switching, the menubar and dock, and even the ability to force quit. See: http://developer.apple.com/mac/library/technotes/KioskMode/Introduction/Introduction.html
It's not a lot of code, it just uses a few different APIs so you'll spend most of your time bouncing between API docs. I suggest writing the screen lock code as its own application (just add a new application target to your Xcode project) and then put the screen locker inside your application bundle. This used to be (as of 10.4) how Apple Remote Desktop implemented the "Lock Screen" functionality, but I can't find the app anymore.
I believe the Cocoa replacement to the SetSystemUIMode API was not introduced until 10.6.
If you can live with Snow-Leopard-only code, the answer is - setPresentationOptions: on NSApplication.
