• How do I save user specific data in an asp.net site?

  - by Greg McNulty

  I just set up user profiles using asp.net 3.5 using wvd. For each user I would like to store data that they will be updating every day. For example, every time they go for a run they will update time and distance. I intend to allow them to also look up their history of distance and time from any past date. My question is, what does the database schema usually look like for such a set up? Currently asp.net set up a db for me when I made user profiles. Do I just add an extra table for every user? Should there be one big table with all users data? How do I relate a user I'd to their specific data? Etc.... I have never done this before so any ideas on how this is usually done would be very helpful. Thank you.

• SQL Server ORDER BY/WHERE with nested select

  - by Echilon

  I'm trying to get SQL Server to order by a column from a nested select. I know this isn't the best way of doing this but it needs to be done. I have two tables, Bookings and BookingItems. BookingItems contains StartDate and EndDate fields, and there can be multiple BookingItems on a Booking. I need to find the earliest startdate and latest end date from BookingItems, then filter and sort by these values. I've tried with a nested select, but when I try to use one of the selected columns in a WHERE or ORDER BY, I get an "Invalid Column Name". SELECT b.*, (SELECT COUNT(*) FROM bookingitems i WHERE b.BookingID = i.BookingID) AS TotalRooms, (SELECT MIN(i.StartDate) FROM bookingitems i WHERE b.BookingID = i.BookingID) AS StartDate, (SELECT MAX(i.EndDate) FROM bookingitems i WHERE b.BookingID = i.BookingID) AS EndDate FROM bookings b LEFT JOIN customers c ON b.CustomerID = c.CustomerID WHERE StartDate >= '2010-01-01' Am I missing something about SQL ordering? I'm using SQL Server 2008.

• Getting "Location" header from NSHTTPURLResponse

  - by aspcartman

  Can't get "Location" header from response at all. Wireshark says that i've got one: Location: http://*/index.html#0;sid=865a84f0212a3a35d8e9d5f68398e535 But NSHTTPURLResponse *hr = (NSHTTPURLResponse*)response; NSDictionary *dict = [hr allHeaderFields]; NSLog(@"HEADERS : %@",[dict description]); Produces this: HEADERS : { Connection = "keep-alive"; "Content-Encoding" = gzip; "Content-Type" = "text/html"; Date = "Thu, 25 Mar 2010 08:12:08 GMT"; "Last-Modified" = "Sat, 29 Nov 2008 15:50:54 GMT"; Server = "nginx/0.7.59"; "Transfer-Encoding" = Identity; } No location anywhere. How to get it? I need this "sid" thing.

• Class to manage e-mail from iPhone

  - by Scott Pendleton

  I'm working on an iPhone app that offers the user the opportunity to send an e-mail in 3 different places in the app, and for 3 different purposes. Rather than put the same code for showing the e-mail composer in 3 different view controllers, shouldn't I develop a separate E-mail class, create an instance, and then set properties such as To, CC, BCC, Body, HTML_Or_Not, and so on? Also, if I create an instance of such a class, and it brings up the e-mail composer, is it OK to release the class even before the e-mail composer has left the screen?

• Using installshield to replace a same-versioned DLL in the GAC

  - by Kevin

  We recently put out an update of one of our apps with a "test" DLL from a third party. The third party does not update their assembly versions on the dll's, only the file versions, so multiple apps can reference different "versions" of it. However, the GAC still allows us to keep the newest version, because it also checks the file version which is always updated. What happened is we were not ready to release this DLL, but it got out there on some customer machines. I would like to put our current live version back out there, but it has an older file version (and the same assembly version) as the test DLL. We have multiple apps referencing this DLL, so I can't simply delete it and drop in the new one. Is there a way to replace the DLL in the GAC? I'm using installshield 2009. Perhaps some sort of custom action upon install?

• Closing an EDM ObjectContext?

  - by David Veeneman

  I am getting started with the ADO.NET Entity Framework 4.0. I have created an EDM and data store for the app, and it successfully retrieves entities. The application holds the EDM's ObjectContext as a member-level variable, which it uses to call ObjectContext.SaveChanges(). So far, so good. I am going to refactor to repositories later. Right now, my question is a bit more basic: When I am finished with the EDM, what do I need to do to release it? Is it as simple as calling Dispose() on the ObjectContext? Thanks for your help.

• Actionscript 3 : XML cached in local testing

  - by Boun

  Hi, My question is about XML loading. I need to avoid xml caching. On a web server, the technique is adding a random param to reload each time the XML file. But on local testing (in Flash CS4 IDE, CTRL + Enter), the following lines are not possible : var my_date : Date; path = "toto.xml?time="+my_date.getSeconds()+my_date.getMilliseconds(); Is there any trick to bypass this issue ? I've read on different forum about the "delete" method, we delete the xml object and then recreate one new. In my case, I put : myXML = null; myXML = new XML ( loadedData ); But it doesn't work at all. I spent many hours on that problem, if anyone has a good solution... Thank you.

• Security when using GWT RPC

  - by gerdemb

  I have an POJO in Google Web Toolkit like this that I can retrieve from the server. class Person implements Serializable { String name; Date creationDate; } When the client makes changes, I save it back to the server using the GWT RemoteServiceServlet like this: rpcService.saveObject(myPerson,...) The problem is that the user shouldn't be able to change the creationDate. Since the RPC method is really just a HTTP POST to the server, it would be possible to modify the creationDate by changing the POST request. A simple solution would be to create a series of RPC functions like changeName(String newName), etc., but with a class with many fields would require many methods for each field, and would be inefficient to change many fields at once. I like the simplicity of having a single POJO that I can use on both the server and GWT client, but need a way to do it securely. Any ideas?

• Excel macro send rich mail using LotusNotes

  - by CC

  Hi everybody. I'm working on a small macro to send mail from excel 2007 using my Lotus Notes session. The sending mail part is working fine. Now I need to send in the body part, a part of a stylesheet (for instance the area from A1:B20). This area has colors, bold font. To send my email here is the code: Set oSess = CreateObject("Notes.NotesSession") Set oDB = oSess.GETDATABASE("", "") Call oDB.OPENMAIL flag = True If Not (oDB.IsOpen) Then flag = oDB.Open("", "") If Not flag Then MsgBox "Can't open mail file: " & oDB.SERVER & " " & oDB.FILEPATH End If On Error GoTo err_handler 'Building Message Set oDoc = oDB.CREATEDOCUMENT Set oItem = oDoc.CREATERICHTEXTITEM("BODY") oDoc.Form = "Memo" 'mail subject oDoc.Subject = "subject" 'mail body oDoc.sendto = "[email protected]" oDoc.body = "my text" oDoc.postdate = Date oDoc.SaveMessageOnSend = True oDoc.visable = True 'Sending Message oDoc.SEND False Does anybody has an idea about how to send a stylesheet ?

• Django: ordering by backward related field property

  - by Silver Light

  Hello! I have two models related one-to-many: a Post and a Comment: class Post(models.Model): title = models.CharField(max_length=200); content = models.TextField(); class Comment(models.Model): post = models.ForeignKey('Post'); body = models.TextField(); date_added = models.DateTimeField(); I want to get a list of posts, ordered by the date of the latest comment. If I would write a custom SQL query it would look like this: SELECT `posts`.`*`, MAX(`comments`.`date_added`) AS `date_of_lat_comment` FROM `posts`, `comments` WHERE `posts`.`id` = `comments`.`post_id` GROUP BY `posts`.`id` ORDER BY `date_of_lat_comment` DESC How can I do same thing using django ORM?

• Choosing between YUI Charts or Google Visualization API

  - by r2b2

  Hello , I'm a bit stuck with which charting library I will use in my project. Im stuck with this two (but also open for other suggestions) For YUI Charts : Pro : - Very robust and configurable Cons : - Uses flash 9 , which might potentially be inaccessible for users without up to date flash version - Does not support export to image (for flash versions < 10 only) For Google Visualization API pros: - small file size for the libraries, - can be exported to static image charts (via separate API call) Cons - limited configuration options So there, please help me decide. YUI charts has the edge over configuration options but Google Visualization API has the edge in terms of accessibility as it uses SVG to render the grapsh instead of Flash. For users that are hand-cuffed by corporate IT prohibitions , they cant just upgrade their Flash version and the page will not work. Thanks!

• Frame of viewForHeaderInSection is always the same size

• css + first load bug + min-height

  - by Henry

  We forked an editor for upcoming release of our CMS. See: http://tinyurl.com/ylbtns2 The editor uses the css of the current template and loads an additional fix.css (inside the iframe) to override some rules: * { background-image: none !important; min-height: 0px !important; } #breadcrumbs, #content .sidebar, #footer, #header, #search_form { display: none; } #content { margin: 0px; width: 100%; } The problem: on first load the "min-height: 0px !important;" seems not to work - on second load the height of the editor iframe is 100px like it should be. Other rules like no background (fix.css) are working on first load and get overridden.

• Complicated football league Dynamic Ordering in MySQL?

  - by Dan

  I have a table 'games' for a football league as follows: date home_team_id away_team_id home_score away_score - 1 2 6 21 - 3 1 7 19 I can't figure out how to dynamically generate a list of team ID's ordered by Wins (then points for if poss)? -- I have this query which works fine when I have a $team_id but of cause then I can only do 1 team at a time, and that doesn't allow for ordering at query level ((SELECT COUNT(*) FROM `games` WHERE ((`home_score` > `away_score`) AND `home_team_id` = '.$team_id.')) + (SELECT COUNT(*) FROM `games` WHERE ((`home_score` < `away_score`) AND `away_team_id` = '.$team_id.'))) AS `wins` I wonder if i can use this with some form of GROUP, or mySQL can know the $team_id itself? I've also tried some multiple JOINs with the 'team' table but they didn't work either. Thanks, Dan

• Invoke an action that is using ASP.NET MVC [Authorize] from outside the application

  - by Nate Bross

  Is this possible? I'd like to expose a URL (action) such as http://mysever/myapp/UpdateHeartbeat/. In my MVC application it looks like [Authorize] [AcceptsVerbs(HttpVerbs.Post)] public ActionResult UpdateHeartbeat() { // update date in DB to DateTime.Now } Now, in my MVC application the user has logged in via FORMS authentication and they can execute that action to their hearts content. What I want to do, is hit that URL progromatically (as part of an API that I wouldl like to build) -- is there a way I can do that without removing the [Authorize] attribute and adding username/password as parameters to the POST?

• Many to Many Association Tables - Is it customary to put additional columns in these tables?

  - by Randy Minder

  We've encountered the following situation in our database. We have table 'A' and table 'B' which have a M2M relationship. The association table is named 'AB' and contains a FK column to table 'A' and a FK column to table 'B'. Now we've identified a need to store additional data about this association. For example, a date when the association occurred, and who made the association etc. We've decided to put these additional columns in the 'AB' association table. However, something tells me this is frowned upon by database purists. On the other hand, it makes no sense to us to create yet an additional table to store this associated data. What's the prevailing thought on this?

• What *collaborative* wireframing / UI mockup tools are out there?

  - by taco

  I'm looking for something that applies the collaboration focus (one location/URL, always up-to-date, multi-person online read/write access anywhere) of google docs / google spreadsheets to wireframing. Bonus points if, like Google Docs, it needs only a browser yet also works offline. More bonus points if it supports automatic revisions. Even more bonus points if you can hand out login-less 'invitation' URLs like Flickr does, instead of forcing people into signing up for accounts or using their home accounts. To start off, there's one called iPlotz, but it didn't enchant me -- ironically, mostly because of its akward UI, which can't hold a candle to omnigraffle (don't let that prevent you from giving it a try though). And no, paper prototyping, wonderful as it is, does not qualify: it does not combine being instantly globally shareable & editable very well :-)

• How to version MVC JavaScript includes

  - by Ed

  I'm working with someone else's code, so I don't know the whole picture, and I don't even know MVC that well, but here's the problem... In Site.Master there's a <%= Html.IncludeJs("ProductPartial")%> which produces this line in the final mark-up <script type="text/javascript" src="/Scripts/release/ProductPartial.js"></script> I made some changes in the JS file, but the old one is obviously cached by the browser, so the changes won't show up until the user refreshes. The usual workaround is to add a version tag at the end of the script source path, but I'm not sure how to do that in this case. Any suggestions?

• Querying MySQL with CodeIgniter, selecting rows where field is NULL

  - by rebellion

  I'm using CodeIgniter's Active Record class to query the MySQL database. I need to select the rows in a table where a field is not set to NULL: $this->db->where('archived !=', 'NULL'); $q = $this->db->get('projects'); That only returns this query: SELECT * FROM projects WHERE archived != 'NULL'; The archived field is a DATE field. Is there a better way to solve this? I know I can just write the query myself, but I wan't to stick with the Active Record throughout my code.

• SSRS 2008 Snapshotting Security

  - by Holy Christ

  Hi, I'm writing a report that will show data based on the User!UserID built into the SSRS infrastructure. The data is sensitive to the user's department. In addition to these department users, there will be admins that should be able to run for all departments, or have a report parameter to run for a specific department. Ideally, I'd like to use SSRS snapshotting so that users can rerun a report they ran on a previous date. It's important that a user can only view the snapshots he created for his department. My questions are: 1.) Does SSRS snapshotting provide a mechanism to limit viewing snapshots by the user that created them? 2.) Will I need to write two reports, one for the admin and one for the department users? I think I do since there isn't a way to secure report parameters. Thanks!

• subversion merge back to trunk

  - by Berryl

  I set up a branch several weeks ago. When some changes were made to the trunk, SVN was committing to the branch, and not the trunk. The changes were minor and applicable to the branch anyway, so I assumed this is how the branch should work. Now that the branch work is finished, I merged back the branch back to my working trunk, assuming SVN would replace the old trunk with the new branch in the repository as well. That is not the case though. My repository trunk is out of date. I would like to make the repository trunk be same as the branch and then delete the branch. How can I do this? Cheers, Berryl Note: I am using tortoise / visualvsn client.
