  • Is there an ORM that allows a "plugin" to extend the database?

    - by IP
    So, I've been searching for the answer to this, but I can't find anything I have an Entity Framework Model (MyModel1) - for now, we'll say this contains a "Users" table It's part of a big app, that has a references to an "Addresses" project The addresses project contains an Entity Framework Model (MyModel2), this contains a Users table, and an Addresses table (pointing to the same database. The main app has a control that edits the user, and in that control it has an "addresses" control which actually exists in the "Addresses" project. To make this work, the User control passes the User object down to the addresses control, however, as the User that's been passed belongs to MyModel1 and not MyModel2, another User object has to be loaded up, then it can be used. This isn't ideal as I've had to load up the User twice. Is there a way of say, MyModel2 extending MyModel1, which effectively just adds a relationship to "User". Or is there an ORM that would handle this better? Or even a design pattern that would handle this better?

    I have layout that has wider background picture than the content area. I have made 970ppx wrapper where the content is. And in body I have backgroud image but I need to have anothen background image above of tht body background image so I have made class bgimg. So basically the markup is like this: But the bgimg is about 1050px wide and thus it gives scrolls when users browser is 1024x768. Is there way of getting rid the scrolls? I mean I want to have have scrollbars if users browrser is narrower thant the 970x wrapper of course. So can I put something like overflow hidden for bgimg class? Hopefully you did understannd what I mean.

  • Is there any way that I can draw fast a chart with too many series? [on hold]

    - by Maryam Bagheri
    I have a project that need to draw a fast chart with many series. I must change start position of drawing to a favor position when user want. .Net Chart is slow in lots of series. I wanted to use this library: http://www.codeproject.com/Articles/32836/A-simple-C-library-for-graph-plotting?msg=4109664#xx4109664xx but loading speed is too slow when count of series increases. When I plot the chart, I must invalidate the chart for updates, drawing speed will be too slow if there are too many series. I need at least 900 series in a chart for this project. I wanted to use multiple layer series to decrease invalidate rate with the idea: http://www.codeproject.com/Articles/84833/Drawing-multiple-layers-without-flicker I do not know this idea would be helpful. I tested LightningChart control but it could not help me.

  • C# asp.net MVC: When to update LastActivityDate?

    - by Oskar Kjellin
    I'm using asp.net mvc and creating a public website. I need to keep track of users that are online. I see that the standard way in asp.net of doing this is to keep track of LastActivityDate. My question is when should I update this? If I update it every time the users clicks somewhere, I will feel a performance draw back. However if I do not do that, people that only surf arround will be listed as offline. What is the best way to do this in asp.net MVC?

  • App crashing on open on Motorola Backflip only

    - by anakin78z
    I have recently published my second app on the Android Market. I've gotten a few e-mails about the app crashing on open, and all users were using the Motorola Backflip. It seems to work fine on all other devices. The app shows the background image, but crashes right after that. Is there something different I have to do when coding for that device? The strange thing is that it is very similar to my first app, which seems to work just fine for them. The major difference is that my second app is a paid app, and uses Android Licence Verification. My implementation should catch any license errors though, and I've tested this on my device. Users have uninstalled and reinstalled the app without success. I'm stumped. The other thing they're reporting is that the icon doesn't even show properly, but rather is a gear in a box, which makes me think that something goes awry very early in the installation process.

  • Best Design for creating Historic Reports on GAE

    - by charming30
    My App requires Daily reports based on various user activities. My current design does not sum the daily totals in database, which means I must compute them everytime. For example A report that shows Top 100 users based on the number of submissions they have made on a given day. For such a report If I have 50,000 users, what is the best way to create daily report? How to create monthly and yearly report with such data? If this is not a good design, then how to deal with such design decision when the metrics of the report are not clear during db design and by the time it is clear we already have huge data with limited parameters (fields). Please advice.

  • Caching for database questions.

    - by SeanD
    When we say caching like using memcahe or Redis, is this a 1:1 caching between the user and the cache or can we cache 1 item and use it for all user? Some items like a Friend list will be 1:1 a that is unique per user. But if i want to cache the auto complete list for city lookups which can be used by any user, will it just store 1 list in the cache used by all users at same time or doe it need to store 1 list per user? Is it possible to cache the entire database, all the lookups, all the users, all their photos, etc using memache or redis? So from the above example: a friend list will be cleared from the cache when the user logs off. But something like city auto complete will stay in the cache 24-7-365, am i correct?

  • Is it better to store user text (such as a blog entry or private messages) in the database or as flat files?

    - by Fredashay
    I'm building a social networking type site that will be storing large chunks of text that's entered by users, such as blog entries and private messages. As such, these will be entered once, with minimal revisions, but many reads by multiple users over time. I'm using MySQL, by the way. My concerns are: Storing large blocks of text on the database will fill the database to capacity eventually. I read somewhere that storing user text in flat files is a security risk? (The filenames will be generated dynamically by the PHP, not by the user.) Storing them as text files may cause them to become out of sync if I ever have to reinitialize the database and restore it from backups. What are all your thoughts and advice, pros and cons?

    - by simone
    hi all, I have a db with users that have all this record . I would like to do a query on a data like CN=aaa, OU=Domain,OU=User, OU=bbbbbb,OU=Department, OU=cccc, OU=AUTO, DC=dddddd, DC=com and I need to group all users by the same ou=department.

Please help me

  • How to model localized items

    - by tweir
    I'm currently designing a e-commerce solution. One of the primary requirements is for the store to support localized item details. The same store must be able to support multiple languages via the user's language selection and/or browser preference. I have two tables: Item (id, sku, price, ...) ItemDetails (item_id, language, title, ...) For each Item, there will be multiple rows corresponding to the item, where the (item_id,language) pair will be unique. I would like to model this as: class Item { public string sku; public double price; public ItemDetails Details; } Based on the user's session, I would like the items returned to have the Details object corresponds to the user's selected language (from their session). What are some approaches for representing this?

  • .net (winforms, not asp) multi-server deployment

    - by poiuyttr
    I have a small .NET WinForms application, and couple of linux servers, DEV and CL1,CL2..CLN (DEV is development server and CL* are servers which belons to our clients, they are in private networks and it's a kind of production servers) I want an update mechanism so that (1) i develop a new version and publish it to a DEV (2) users of DEV-server install latest version from DEV (3) users of CL2 (employees of client2) install stable version from CL-2 directly (4) application checks for updates using server it was installed from (so, if it was installed from CL-2, it should check CL-2 for updates) (5) i should be able to propogate the update to a selected CL-server (using just file copy & maybe sed; not republishing), if i want that (and if i don't, that CL-server will have an old version until manually i update it) I tried to use clickonce, but looks like it meets only first two requirements. What should i do?

  • URL Rewriting from a subdomain to main domain!

    - by JCHASE11
    Hello. I am developing a pretty large website for a client, and its about 90% complete. It is currently hosted on a subdomain like so: now: v2.websitehere.com when complete: www.websitehere.com My problem is that SO much of this site is linked to the temporary subdomain. The newsletter service, multiple google apis, etc. I also have multiple blogs installed that would be hard to move over. Literally, I have over 20 blogs hosted on the subdomain. I also have other PHP scripts that utilize SQL databases. So, what I am getting at is that a migration would be very difficult: time consuming, frustrating, and not something I want to do. I am looking for a a good solution...similar to Wordpress's URL rewriting. Is there something I can do with .htaccess file? Any ideas would be MUCH appreciated.

  • .htaccess password and forced login

    - by Boco
    I have password protected website with .htaccess. What I want to do now is to force users to login from the index.html page and not from any other which they can do now. ie. I have index.html (the main page) and I have two other pages 1.html and 2. html also protected with .htaccess password. Users can now type http://www.mypage.com/1.html and they will be asked for login data but I would like to force them (before they are asked for login details) to index.html to login. After they are loggedin they can use any link (ie.1.html or 2.html) as they want. Can this be done by using .htaccess? I would need the whole code. Thank you!

  • Where does static variable work in C# page. At Application level or Page Level

    - by Shantanu Gupta
    I had an interview today and every thing was going very good, but then an interviewer asked me a question Where Does Static Variable Work in C#- At Application Level or At Page Level. I was not very much clear about this answer as I only knew that static variables are stored on heap and I didn't knew anything about web related thing about it. Then tried to make me more clear by giving an example that in a page I am using static variable and three users are accessing the page one of the user updates the value of static variable, What value will be visible to remaining two users an old copy or the update will be reflected.

  • iPhone - In App Purchase questions

    - by diwup
    Hey guys, Merry Christmas. I have two questions on In App Purchase. iAP application process: do I need to submit my iAP items applications, wait for Apple's responses, then build my app accordingly, or, I can just create some iAP items, build them into my app, then after everything's done, submit my binary to Apple? Intermediary currency: on Apple's documentation I found these sentences: "You may not offer items that represent intermediary currency because it is important that users know the specific good or service that they are buying." However, I found a few apps on the App Store offering its users with different kinds of intermediary currency. I'm confused. Is this a gray area in which we developers can play some tricks? Thanks in advance. Di

  • Django: HTTPS for just login page?

    - by Mark
    I just added this SSL middleware to my site http://www.djangosnippets.org/snippets/85/ which I used to secure only my login page so that passwords aren't sent in clear-text. Of course, when the user navigates away from that page he's suddenly logged out. I understand why this happens, but is there a way to pass the cookie over to HTTP so that users can stay logged in? If not, is there an easy way I can use HTTPS for the login page (and maybe the registration page), and then have it stay on HTTPS if the user is logged in, but switch back to HTTP if the user doesn't log in? There are a lot of pages that are visible to both logged in users and not, so I can't just designate certain pages as HTTP or HTTPS.

  • Which PHP calendar will suit my needs? Or build my own?

    - by John
    There are so many web based calendars out there that I'm not sure which will best suit my purposes. I want to create an events calendar, which I suppose looks and functions in much the same way as google calendar. But users shouldn't need to sign up for a gmail account or a google account. Users of my social network website should be able to create events in the calendar and share it with other friends in their "friend network". In month, year or day views, you can mouse hover events to see a bubble dialog that lists events in detail. People need to pay a monthly fee to use my website (not sure if this prevents me from using google apps). So is something like Google Calendar the way to go? Or are there other php/javascript calendars out there that already meet my needs? Or will it just save me more time to build my own?

  • Reporting sanitized user input to the user via AJAX

    - by JimBo
    I am writing some code to give live feedback to the user on the validation of a form using AJAX. I have got it checking length and if the field is empty. Now I want it to sanitize the users input and if the sanatized input differs from the users original input then tell them which characters are not allowed. The code I have written so far works except some characters most notably a '£' symbol result in no response. I think it relates to json_encode and its encoding. Here is the code: $user_input = 'asdfsfs£'; $strip_array = str_split(strip($user_input)); $orig_array = str_split($user_input); $diff_array = array_diff($orig_array,$strip_array); $diff_str = implode(', ',$diff_array); $final = json_encode($diff_str); function strip($input){return htmlentities(strip_tags($input),ENT_QUOTES);} Hope someone can figure out a solution.

  • Android: Referring to a string resource when defining a log name

    - by spookypeanut
    In my Android app, I want to use a single variable for the log name in multiple files. At the moment, I'm specifying it separately in each file, e.g. public final String LOG_NAME = "LogName"; Log.d(LOG_NAME, "Logged output); I've tried this: public final String LOG_NAME = (String) getText(R.string.app_name_nospaces); And while this works in generally most of my files, Eclipse complains about one of them: The method getText(int) is undefined for the type DatabaseManager I've made sure I'm definitely importing android.content.Context in that file. If I tell it exactly where to find getText: Multiple markers at this line - Cannot make a static reference to the non-static method getText(int) from the type Context - The method getText(int) is undefined for the type DatabaseManager I'm sure I've committed a glaringly obvious n00b error, but I just can't see it! Thanks for all help: if any other code snippets would help, let me know.

  • db optimization - have a total field or query table?

    - by Dorian Fife
    I have an app where users get points for actions they perform - either 1 point for an easy action or 2 for a difficult one. I wish to display to the user the total number of points he got in my app and the points obtained this week (since Monday at midnight). I have a table that records all actions, along with their time and number of points. I have two alternatives and I'm not sure which is better: Every time the user sees the report perform a query and sum the points the user got Add two fields to each user that records the number of points obtained so far (total and weekly). The weekly points value will be set to 0 every Monday at midnight. The first option is easier, but I'm afraid that as I'll get many users and actions queries will take a long time. The second option bares the risk of inconsistency between the table of actions and the summary values. I'm very interested in what you think is the best alternative here. Thanks, Dorian
