阅读更多关于 Rails 3: How to store screen resolution?

I want to store user's screen resolution in database when user login. How to detect and store it to database when user login? Read it with JavaScript (browsers don't send screen resolution information by default, so it isn't available to Ruby or anything else server side unless you make it so), then generate a hidden input , set the name and value based on the data you've gathered, then add it to the form containing the username and password inputs. Oh, and you might find the window size more useful than the screen resolution. Not everybody maximizes their windows. 来源： https://stackoverflow

阅读更多关于 Dealing with different resolutions for pixel based android game

问题 I am developing a 2D platformer game for the android platform, so I don't really care about the screen DPI, but much more about the actual resolution in pixels. From what I've gathered on the net, there are a couple of different resolutions (and aspect ratios) present. According to my search, the two resolutions that are currently widespread are 480x320 (1.5) and 800x480 (1.666), is that right? I'd like to target these two resolutions to reach most customers. Now, I can deal with the

问题 I'm connecting to CentOS 7 VM from Hyper-V from Windows 8.1. The full screen mode is not working. I need to fix that. Other VMs including CentOS 6 and Windows Server have no problems. These are some observations I made when I connect to that VM from Hyper-V Manager. CentOS 7, while booting, displays this warning "fast TSC calibration failed". I read that this is not a problem but I'm not sure. Everything else is working in the VM except not being able to work in the full screen mode of my

First of all sorry for the (maybe not so specific) title as it consists of multiple topics. The issue atm i'm having is related to my test automation setup.

First of all how i have the Win machine set up: As Ranorex is a GUI test automation tool it needs to have the components visible for the AUT (application under test) and for this reason you need

问题 I'm coming from Libgdx engine to Unity and I'm a beginner programmer. I try to make a game in Unity for Android and iOS devices, but I have a problem with the aspect ratio/resolution scaling.

On the other side, in Unity if I make a game it will crop the screen to the chosen
