Some time ago while looking at some pixel art work I got an idea to create a retro pixel art game for Windows 10. The choice was obvious, Sokoban. I have a very special relationship with the Sokoban game. The Delpi version of Sokoban was the first game I ever created. I later ported it to all the platforms I played with, namely J2ME (for my Siemens S60 phone), Linux (using Kylix which was basically a Delphi for Linux), Windows Phone 7 and now Sokoban Pixel for the Universal Windows Platform.
Creating better forms in Windows Phone apps
If you are a Windows Phone user you must know that filling in forms in apps is usually a real pain. There is no good way to move from one input to another or to collapse the keyboard. The whole process becomes a struggle, tapping outside the input fields to collapse the keyboard allowing you to scroll to the next input or to the submit button at the top of the screen, usually occluded by the keyboard.
The typical struggle to get to the last input fields and the submit button may look like this
There is no guidance on how to approach this. Take a look at the Store app on Windows 10 mobile, the perfect example of bad UI and UX directly from Microsoft and try review an app. You fill in the title of the review, then struggle to go into the review text input, you have to tap somewhere above the input to hide the keyboard, but not to hit the stars control … just an UX disaster.[Read More]
Using Tooltips to make better menus in Windows apps
If you use Windows apps with navigation menus consisting of icons, you may have noticed that some of those apps show you a text when hovering above those icons. This is a nice touch for the users, allowing them to quickly grasp the meaning of the menu icons without the need to click them or to expand the menu (if available).
Implementing this kind of hovers is really easy thanks to the
ToolTipService that is available in Windows 8.1 and Windows 10 UWP. You can add
<ToolTipService.ToolTip> with any element and include basically any XAML content as the tooltip. Here is a sample from the animation using a simple localized
Choosing an image from gallery or camera a bit better in Universal Windows apps
When developing Windows Phone apps you may encounter a use case when you have to allow the user to either pick a photo from the photos gallery in the photo or a take a new photo using the phone’s camera. One example of this may be the registration process when the user may choose a profile picture.
In Windows Phone 8.1, this task is quite simple, just use the
FileOpenPicker. It allows you to pick a photo from the gallery or take a new photo. Just take a look at this animation showing how the users takes a new photo using the phone’s camera.
Using Hockey App to distribute Windows Phone apps
Distributing Windows Phone apps to testers has always been a pain. The Private Beta in the Windows Store intended for this is not very flexible and it got much worse with Windows 10 (generating promotional code that can take up to 24 hours).
One of the better ways to solve the beta build distribution is using a service like Hockey App, that Microsoft recently acquired. To be able to use Hockey App (or any other service) you need to buy a $299 certificate from Symantec.
You then use the certificate to sign the XAP or APPX files of your app. Those signed binaries can be than installed on devices with the correct application enrollment token directly from Hockey App, bypassing the Windows Store.
One of my clients got persuaded to try this approach after some problem with the Windows Store Private Beta and bough the certificate. It took a week for the purchase to go through and another week to finally get the certificate in the correct PFX format from Symantec.[Read More]
