  • How to check if user submit Arabic words from a form?

    - by ronanray
    Hi Experts.. Is there any reliable way to check if user has entered Arabic words into a form and tries to submit it? Can Javascript handle this? Or, only server script like .NET can do this? I'm thinking that if possible the script should directly prevent the user from inputting Arabic words into the form and show an alert pop up. Please share any examples if you have any idea how to do it. Thanks

  • A good way in Visual Studio to have user entered time frame?

    - by Ben
    Hi, Does anyone know of a good way to have a user enter an amount of time (hours and minutes) using visual studio controls? At the moment i have two numeric up downs, one for time and one for minutes that i then parse to create a timespan. The only other idea i have is a text box that a user can enter a "00:00" time in, and validate the input. Both of these ways seem a bit bad (in UI terms) though. Any ideas? Thanks

  • Way to get logged in user in Expression Engine?

    - by Andrew G. Johnson
    Hi all, I am using Expression Engine in part of a site I am developing and other parts are just using my own PHP. My question is how can I tell who the user is logged in as on a non-EE page? I have access to the EE cookies and the EE database but couldn't find a way to use these values to figure out who the user is. I have a list of all the cookie keys/values at: http://andrewgjohnson.com/cookies.html

  • Is frozenset adequate for caching of symmetric input data in a python dict?

    - by Debilski
    The title more or less says it all: I have a function which takes symmetric input in two arguments, e.g. something like def f(a1, a2): return heavy_stuff(abs(a1 - a2)) Now, I want to introduce some caching method. Would it be correct / pythonic / reasonably efficient to do something like this: cache = {} def g(a1, a2): return cache.setdefault(frozenset((tuple(a1), tuple(a2))), f(a1, a2)) Or would there be some better way?

  • Good object/DB set-up for CMS-esque app for managing content and user permissions?

    - by sah302
    Hi all, so I am writing a big CMS-esque app to allow users to manage web content through web applications, I've got a pretty good db-driven user permission system going, but am having trouble coming up with a good way to handle content groups and pages, I've got a couple options and not sure which one to take. Furthermore, I am not sure how to handle static page updates that have no 'widgets' in them. My current set-up for permissions is this: Objects: User, UserGroup, UserUserGroup, UserGroupType Standard many to many relationship User -> UserUserGroup <- UserGroup each Usergroup has a UserGroupType, which could be anything from Title, Department, to PermissionGroup. PermissionGroup manages the permissions. Right now on a per page basis I check permissions based on their PermissionsGroups. So for a page which has CMS features for a news widget, I check for permission groups of "Site Admin" and "News Admin". Now the issue I am coming to is, the site has many different departments involved. No problem I think, I can just have a EntityContentGroup so any widget app can be used for any departments. So my HR department, each of their news items would be in the EntityContentGroup with the news item ID, and content group of "HR" or "HR News". But maybe this isn't the most efficient way to go about it? I don't want to put the content group simply as a NewsItemType because some news items could apply to multiple areas, so I want to be able to assign them to as many areas as I want. Likewise, all of my widget apps have this, so that's why I decided to choose EntityContentGroup and not just NewsItemContentGroup. I was also thinking well instead of doing a contentGroup do a Page object that says which page some entity should be on. It seems almost like the same thing, but would I want to use Page for something else? I was thinking Page would be used for static pages with no widgets, a simple Rich Text Editor can edit the content of that page and I save that item to a page?? And then instead of doing a page level check for UserGroup permissions, would it be better to associate a usergroup to a contentgroup, and then just depending on what contentGroup content on the page is displayed, determine the permissions through that relationship? Is that better? I am not sure at this point. I guess I am just getting a tad overwhelmed at this is the largest app in scope and size that I have ever written. What is the best approach for this based on my current user permission set-up?

  • How do I track the method the user is looking at in VS 2010 IDE as an Addin

    - by Rob
    I have been wandering around the object model for VS 2010 and haven't been able to work out the best method for watching what the user is looking at in the main edit window. I know that each Class/method/property is broken down into its own . What I would ideally like is to hook to an event which says "The user has moved the cursor onto Project.Class.Method" and ideally "and is looking at line 4". Any suggestions?

  • Why does Joda time change the PM in my input string to AM?

    - by Tree
    My input string is a PM time: log(start); // Sunday, January 09, 2011 6:30:00 PM I'm using Joda Time's pattern syntax as follows to parse the DateTime: DateTimeFormatter parser1 = DateTimeFormat.forPattern("EEEE, MMMM dd, yyyy H:mm:ss aa"); DateTime startTime = parser1.parseDateTime(start); So, why is my output string AM? log(parser1.print(startTime)); // Sunday, January 09, 2011 6:30:00 AM

  • Best way for user authentication on JavaEE 6 using JSF 2.0?

    - by ngeek
    I'm wondering what the current state of art recommendation is regarding user authentication for a web application making use of JSF 2.0 (and if any components do exist) and JEE6 core mechanisms (login/check permissions/logouts) with user information hold in a JPA entity. The Sun tutorial is a bit sparse on this (only handles servlets). This is without making use of a whole other framework, like Spring-Security (acegi), or Seam, but trying to stick hopefully with the new Java EE 6 platform (web profile) if possible. Thanks, Niko
