usability

问题 I am providing registered members of a website a weekly mailing which contains URLs to private pages on the website. For usability purposes, I don't want the user to have to provide their credentials after they click on the URL. I am using the ASP.NET Membership provider model. Question How can I implement this so that the user can be logged in by virtue of clicking a specialized URL link? 回答1: You could send them a URL with a very long, randomly generated number (e.g. a GUID), which is also

问题 I want to create an application in android in which the user selects a certain day in the future and then, when that day arrives he will get a notification (I know that this can be done through the Calendar or the notes but that doesn't matter in my case). I have two problems concerting the previous: a. How should I implement the notification ? I read elsewhere about adding events to the Google Calendar of the user - but that is not standard. Should I implement a service that checks to see if

问题 I'm a developer and a long-time Windows user with an obsession about making my system as convenient to use as possible. Yesterday I thought about something that has always annoyed me in Windows and that I've taken for granted, and I realized that I have a better idea for how it could work, and I'm now wondering whether it's possible to tweak Windows to work like that. The thing that annoys me is when windows steal focus. For example, I could be running an installer for some program. While it

问题 I know that I can mark unsaved files with asterisk if I check the corresponding check box in settings. But when I close the tab IDEA is not asking me "Do you want to save changes?". Tab is just closed and nothing in the project structure is not indicating that I have unsaved file. When I run the application it just saves the file and run the app. Can I make IntelliJ IDEA to ask me that there is unsaved files in my project that I should now about before launching ? 回答1: You can't, at least not

问题 For example, Windows Forms Designer offers to place my controls on the form the way there are 12 pixels between form border and control border. It seems too much to me. Is it standard value? Also, as I understand standard button height should be 23 pixels. Am I right? Is there any documents that state all this? And can I setup this default values in Visual Studio (for example what if want default margin between control and form borders, when the snap appears, to be 6 pixels instead of 12)?

问题 Which would be good write ALT text for a photo of kid which is smiling and sitting in garden?

问题 As a UI guy (coding and designing user interfaces) I often find myself in the odd situation arguing about the quality of userinterfaces with programmers and other "laymen". I find it somewhat hard to argue about things like colors, icons or layout and it doesn't seem that there is a factual right or wrong. But still - without having a convincing argument I still know (i.e. feel) that sometimes a solution is just wrong. What is your approach to this? Do you let costly usability test decide or

问题 When it comes to putting the submit and reset buttons on your forms, what order do you use? [SUBMIT] [RESET] or [RESET] [SUBMIT] This issue has come up countless times at work... So, in your opinion, which is the most usable for online users? I personally favor the latter, but some people tend to think otherwise. 回答1: In addition to the suggestions given already, I would like to add that the submit button should be an actual button where as reset or cancel just a link making it different from

问题 Does anyone else think that the add view dialog in VS is useless or is it just me? Why is there no search/filtering in there? I can not even paste the type name (without namespace) there to speed up the view creation. Plus, there are a lot of irrelevant classes there, including classes from all referenced libraries. Am I missing something or Microsoft never did any usability testing with that?? Is it possible to filter out types/assemblies in the dialog and/or better navigation compared to

问题 I am debating whether to hide or not to hide the system tray in a Windows Phone 7 application. I've not found any general suggestions on this issue -the official Windows Phone design guidelines don't address this issue at all - except for Jeff Wilcox's blog post who suggested that he personally likes to see the system tray in applications. I'd like some general advice on this issue from other Windows Phone developers. Some reasons for showing the system tray are Doesn't take up that much
