  • NHibernate Criteria question

    - by Jeneatte Jolie
    I have a person object, which can have unlimited number of first names. So the first names are another object. ie person --- name             --- name             --- name What I want to do is write an nhiberate query using which will get me a person who has certain names. so one query might be find someone whose names are alison and jane and philippa, then next query may be one to find someone whose names are alison and jane. I only want to return people who have all the names I'm search on. So far I've got ICriteria criteria = session.CreateCriteria(typeof (Person)); criteria.CreateAlias("Names", "name"); ICriterion expression = null; foreach (string name in namesToFind) { if (expression == null) { expression = Expression.Like("name.Value", "%" + name + "%"); } else { expression = Expression.Or( expression, Expression.Like("name.Value", "%" + name + "%")); } } if (expression != null) criteria.Add(expression); But this is returning every person with ANY of the names I'm searching on, not ALL the names. Can anyone help me out with this? Thanks!

  • How to implement a 'safe' periodical executer without using the Rails helpers?

    - by Robbie
    I am very new to Ruby on Rails and was never really big on writing JavaScript, so the built in helpers were like a tiny silce of heaven. However I have recently learned that using the helper methods creates "obtrusive javascript" so I am doing a tiny bit of refactoring to get all this messy code out of my view. I'm also using the Prototype API to figure out what all these functions do. Right now, I have: <%= periodically_call_remote(:url => {:action => "tablerefresh", :id => 1 }, :frequency => '5', :complete => "load('26', 'table1', request.responseText)")%> Which produces: <script type="text/javascript"> //<![CDATA[ new PeriodicalExecuter(function() {new Ajax.Request('/qrpsdrail/grids/tablerefresh/1', {asynchronous:true, evalScripts:true, onComplete:function(request){load('26', 'table1', request.responseText)}, parameters:'authenticity_token=' + encodeURIComponent('dfG7wWyVYEpelfdZvBWk7MlhzZoK7VvtT/HDi3w7gPM=')})}, 5) //]]> </script> My concern is that the "encodeURIComponent" and the presence of "authenticity_token" are generated by Rails. I'm assuming these are used to assure the validity of a request. (Ensuring a request comes from a currently active session?) If that is the case, how can I implement this in application.js 'safely'? It seems that the built in method, although obtrusive, does add some beneficial security. Thanks, in advance, to all who answer.

  • Fast, easy, and secure method to perform DB actions with GET

    - by rob - not a robber
    Hey All, Sort of a methods/best practices question here that I am sure has been addressed, yet I can't find a solution based on the vague search terms I enter. I know starting off the question with "Fast and easy" will probably draw out a few sighs, so my apologies. Here is the deal. I have a logged in area where an ADMIN can do a whole host of POST operations to input data relating to their profile. The way I have data structured is pretty distinct and well segmented in most tables as it relates to the ID of the admin. Now, I have a table where I dump one type of data into and differentiate this data by assigning the ADMIN's unique ID to each record. In other words, all ADMINs have this one type of data writing to this table. I just differentiate by the ADMIN ID with each record. I was planning on letting the ADMIN remove these records by clicking on a link with a query string - obviously using GET. Obviously, the query structure is in the link so any logged in admin could then exploit the URL and delete a competitor's records. Is the only way to safely do this through POST or should I pass through the session info that includes password and validate it against the ADMIN ID that is requesting the delete? This is obviously much more work for me. As they said in the auto repair biz I used to work in... there are 3 ways to do a job: Fast, Good, and Cheap. You can only have two at a time. Fast and cheap will not be good. Good and cheap will not have fast turnaround. Fast and good will NOT be cheap. haha I guess that applies here... can never have Fast, Easy and Secure all at once ;) Thanks in advance...

  • Keeping cached browser data inside ASP update panel textboxes/dropdowns for browser back click

    - by pmlevere
    I'm new in VB.net/asp and am running a VB web application in a visual database program called IronSpeed designer. I'm primarily using IronSpeed in this case for its login/role security features. I have a basic two page setup for this app. The user logs in then is taken to AccountEntry.aspx, they enter data into textboxes and select some dropdown values that are linked to a sql database, then they click "submit" to move to Results.aspx. On Results.aspx, the user can change data and then generate several types of reports (PDF, Excel, etc). I'm used to setting up ASP controls inside ASPContent areas, and in these areas if a user performs a browser back click the previously entered data will still be on the page for potential user modification. However in this web app, IronSpeed is setting up the page and asp controls inside an asp update panel. It appears inside an asp update panel, cached values can't be seen on a browser back click. In this case, it's important that the orginally entered values still be there for the user experience if the user advances to Results.aspx then clicks browser back to modify a value on AccountEntry.aspx. If I have to I'll setup Session Variables and disable browser clicking, but that is last resort. Is there any way to save cached data inside an asp update panel and have it there for a browser back click?

  • Generate and download a text file in javascript

    - by Mark B
    All my research so far suggests this can't be done, but I'm hoping someone here has some cunning ideas. I have a form on a website which allows users to bulk upload lots of URLs to add to a list on the server. There's quite a lot of server-side processing to do on each URL, so to avoid timeouts and to display progress, I've implemented the upload using jQuery to submit the URLs one at a time using ajax. This is all working nicely. However, part of the processing on each URL is deduplicating it against the complete list. The ajax call returns a status indicating either a successful upload or a rejection due to duplication. As the upload progresses, I tell the user how many URLs have been rejected as duplicates (along with overall progress and ETA). The problem now is how to give the user a complete list of the failed duplicate URLs. I've kept them in an array in my jQuery, and would like the user to be able to click on a link on the form to download a text file containing those URLs. Is this possible just using client-side processing? The server-side processing basically handles a single keyword at a time. I'd rather not have to store the duplicates in a database table with some kind of session key which gets sent with every ajax call, and is then used at the end to generate the text file server-side (and then gets cleaned up some time later). I can see how to do this, but it seems very clunky and a bit 20th century.

  • Relational MySQL - fetched properties?

    - by Kelso.b
    I'm currently using the following PHP code: // Get all subordinates $subords = array(); $supervisorID = $this->session->userdata('supervisor_id'); $result = $this->db->query(sprintf("SELECT * FROM users WHERE supervisor_id=%d AND id!=%d",$supervisorID, $supervisorID)); $user_list_query = 'user_id='.$supervisorID; foreach($result->result() as $user){ $user_list_query .= ' OR user_id='.$user->id; $subords[$user->id] = $user; } // Get Submissions $submissionsResult = $this->db->query(sprintf("SELECT * FROM submissions WHERE %s", $user_list_query)); $submissions = array(); foreach($submissionsResult->result() as $submission){ $entriesResult = $this->db->query(sprintf("SELECT * FROM submittedentries WHERE timestamp=%d", $submission->timestamp)); $entries = array(); foreach($entriesResult->result() as $entries) $entries[] = $entry; $submissions[] = array( 'user' => $subords[$submission->user_id], 'entries' => $entries ); $entriesResult->free_result(); } Basically I'm getting a list of users that are subordinates of a given supervisor_id (every user entry has a supervisor_id field), then grabbing entries belonging to any of those users. I can't help but think there is a more elegant way of doing this, like SELECT FROM tablename where user->supervisor_id=2222 Is there something like this with PHP/MySQL? Should probably learn relational databases properly sometime. :(

  • Secure web module for paid subscribtion

    - by DarkJaff
    Hello everyone, I'm building a website (a community web site like digg) but we will soon release a new feature that people will need to pay for. Right now, our website is in pure C# in .NET, very simple pages with some AJAX. When the member log in, there is no HTTPS. Everything is check with session and the internal validation that I do. What we need, is that when the people are logged in, they can click on a link a proceed to a payment (Paypal, credit card, etc). After the payment is done, the "billing module" will return a value to my site to validate that the payment is done so the account will be flagged as "paying member". I'm guessing this is the way to do, maybe I'm wrong! So my questions are: -What is the name of this kind of billing module? (I will do some research on that) -Do you know any ready to go module that does this kind of thing? -(I push my luck) Do you know any FREE module that do this kind of things. If something is not clear, don't hesitate to ask question :) Thanks a lot! DarkJaff

  • How important is it to use SSL on every page of your website?

    - by Mark
    Recently I installed a certificate on the website I'm working on. I've made as much of the site as possible work with HTTP, but after you log in, it has to remain in HTTPS to prevent session hi-jacking, doesn't it? Unfortunately, this causes some problems with Google Maps; I get warnings in IE saying "this page contains insecure content". I don't think we can afford Google Maps Premier right now to get their secure service. It's sort of an auction site so it's fairly important that people don't get charged for things they didn't purchase because some hacker got into their account. All payments are done through PayPal though, so I'm not saving any sort of credit card info, but I am keeping personal contact information. Fraudulent charges could be reversed fairly easily if it ever came to that. What do you guys suggest I do? Should I take the bulk of the site off HTTPS and just secure certain pages like where ever you enter your password, and that's it? That's what our competition seems to do.

  • Cocoa document-based app: Notification not always received by observer

    - by roysolay
    Hi, I hope somebody can help with my notification problem. I have a notification which looks to be set up correctly but it isn’t delivered as expected. I am developing a document based app. The delegate/ document class posts the notification when it reads from a saved file: [[NSNotificationCenter defaultCenter] postNotificationName:notifyBsplinePolyOpened object:self]; Logging tells me that this line is reached whenever I open a saved document. In the DrawView class, I have observers for the windowOpen notification and the bsplinePoly file open notification: [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(mainWindowOpen:) name:NSWindowDidBecomeMainNotification object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(savedBspline:) name:notifyBsplinePolyOpened object:nil]; - (void) mainWindowOpen:(NSNotification*) note { NSLog(@"Window opened"); _mainWindow = [note object]; } - (void) savedBspline:(NSNotification*) note { NSLog(@"savedBspline called"); NSLog(@"note is %@", [note name]); } The behavior is odd. When I save and close the main window and reopen it, I get the “Window opened” message but not the “savedBspline called” message. If I leave a main window open and open a previously saved session, I get the “Window opened” message and the “savedBspline called” message. I have searched online discussion and Apple DevCenter documentation but I have not seen this problem.

  • PHP with Javascript: Email confirmation script not working

    - by Josh K
    Hey Heres what i got: echo "<script type=\"text/javascript\"> function finishForm() { var answer = confirm('Are you sure these are the teams you want to enter with?'); if (answer) { if(document.getElementByID(emailconfirm).value == ".$_SESSION[Email].") { form.action=\"esubmit.php\"; form.submit(); } else { alert('E-mail address do not match'); return false; } } } function restartForm() { var answer = confirm('Are you sure you want to start over?'); if (answer) { form.action=\"e1.php\"; form.submit(); } } </script>"; I have a regular button calling this function. emailconfirm is a text input. I want to confirm that they have chosen the right teams, then check if the email in the session and the email confirmation text match. If they do match Then i want to submit the form. If they dont match, I want to alert the user they dont match, and just return to page so user can check emails and then resubmit. This script is in my header. EDIT: Haha sorry i submitted one before and it didnt go through, forgot to add my problem!! When you click the button it comes up with the confirmation, clicking either yes or no doesnt do anything. The alert doesnt pop up if they dont match and if they do match it doesnt submit. Also it might be good to note I had it without the email confirmation if statement and it worked fine (going to the submit page)

  • Work around for MessageNotReadableException in Java

    - by Hari
    Hi, I am building a small api around the JMS API for a project of mine. Essentially, we are building code that will handle the connection logic, and will simplify publishing messages by providing a method like Client.send(String message). One of the ideas being discussed right now is that we provide a means for the users to attach interceptors to this client. We will apply the interceptors after preparing the JMS message and before publishing it. For example, if we want to timestamp a message and wrote an interceptor for that, then this is how we would apply that ...some code ... Message message = session.createMessage() ..do all the current processing on the message and set the body for(interceptor:listOfInterceptors){ interceptor.apply(message) } One of the intrerceptors we though of was to compress the message body. But when we try to read the body of the message in the interceptor, we are getting a MessageNotReadableException. In the past, I normally compressed the content before setting it as the body of the message - so never had to worry about this exception. Is there any way of getting around this exception?

  • EJB and JPA and @OneToMany - Transaction too long?

    - by marioErr
    Hello. I'm using EJB and JPA, and when I try to access PhoneNumber objects in phoneNumbers attribute of Contact contact, it sometimes take several minutes for it to actually return data. It just returns no phoneNumbers, not even null, and then, after some time, when i call it again, it magically appears. This is how I access data: for (Contact c : contactFacade.findAll()) { System.out.print(c.getName()+" "+c.getSurname()+" : "); for (PhoneNumber pn : c.getPhoneNumbers()) { System.out.print(pn.getNumber()+" ("+pn.getDescription()+"); "); } } I'm using facade session ejb generated by netbeans (basic CRUD methods). It always prints correct name and surname, phonenumbers and description are only printed after some time (it varies) from creating it via facade. I'm guessing it has something to do with transactions. How to solve this? These are my JPA entities: contact @Entity public class Contact implements Serializable { private static final long serialVersionUID = 1L; @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; private String name; private String surname; @OneToMany(cascade = CascadeType.REMOVE, mappedBy = "contact") private Collection<PhoneNumber> phoneNumbers = new ArrayList<PhoneNumber>(); phonenumber @Entity public class PhoneNumber implements Serializable { private static final long serialVersionUID = 1L; @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; private String number; private String description; @ManyToOne() @JoinColumn(name="CONTACT_ID") private Contact contact;

  • How to map a Dictionary<string, string> spanning several tables

    - by Kim Johansson
    I have four tables: CREATE TABLE [Languages] ( [Id] INTEGER IDENTITY(1,1) NOT NULL, [Code] NVARCHAR(10) NOT NULL, PRIMARY KEY ([Id]), UNIQUE INDEX ([Code]) ); CREATE TABLE [Words] ( [Id] INTEGER IDENTITY(1,1) NOT NULL, PRIMARY KEY ([Id]) ); CREATE TABLE [WordTranslations] ( [Id] INTEGER IDENTITY(1,1) NOT NULL, [Value] NVARCHAR(100) NOT NULL, [Word] INTEGER NOT NULL, [Language] INTEGER NOT NULL, PRIMARY KEY ([Id]), FOREIGN KEY ([Word]) REFERENCES [Words] ([Id]), FOREIGN KEY ([Language]) REFERENCES [Languages] ([Id]) ); CREATE TABLE [Categories] ( [Id] INTEGER IDENTITY(1,1) NOT NULL, [Word] INTEGER NOT NULL, PRIMARY KEY ([Id]), FOREIGN KEY ([Word]) REFERENCES [Words] ([Id]) ); So you get the name of a Category via the Word - WordTranslation - Language relations. Like this: SELECT TOP 1 wt.Value FROM [Categories] AS c LEFT JOIN [WordTranslations] AS wt ON c.Word = wt.Word WHERE wt.Language = ( SELECT TOP 1 l.Id FROM [Languages] WHERE l.[Code] = N'en-US' ) AND c.Id = 1; That would return the en-US translation of the Category with Id = 1. My question is how to map this using the following class: public class Category { public virtual int Id { get; set; } public virtual IDictionary<string, string> Translations { get; set; } } Getting the same as the SQL query above would be: Category category = session.Get<Category>(1); string name = category.Translations["en-US"]; And "name" would now contain the Category's name in en-US. Category is mapped against the Categories table. How would you do this and is it even possible?

  • Event feed implementation - will it scale?

    - by SlappyTheFish
    Situation: I am currently designing a feed system for a social website whereby each user has a feed of their friends' activities. I have two possible methods how to generate the feeds and I would like to ask which is best in terms of ability to scale. Events from all users are collected in one central database table, event_log. Users are paired as friends in the table friends. The RDBMS we are using is MySQL. Standard method: When a user requests their feed page, the system generates the feed by inner joining event_log with friends. The result is then cached and set to timeout after 5 minutes. Scaling is achieved by varying this timeout. Hypothesised method: A task runs in the background and for each new, unprocessed item in event_log, it creates entries in the database table user_feed pairing that event with all of the users who are friends with the user who initiated the event. One table row pairs one event with one user. The problems with the standard method are well known – what if a lot of people's caches expire at the same time? The solution also does not scale well – the brief is for feeds to update as close to real-time as possible The hypothesised solution in my eyes seems much better; all processing is done offline so no user waits for a page to generate and there are no joins so database tables can be sharded across physical machines. However, if a user has 100,000 friends and creates 20 events in one session, then that results in inserting 2,000,000 rows into the database. Question: The question boils down to two points: Is this worst-case scenario mentioned above problematic, i.e. does table size have an impact on MySQL performance and are there any issues with this mass inserting of data for each event? Is there anything else I have missed?

  • Passing information safely between Wicket and Hibernate in long running conversations

    - by Peter Tillemans
    We are using Wicket with Hibernate in the background. As part of out UI we have quite long running conversations spanning multiple requests before the updated information is written back to the database. To avoid getting hibernate errors with detached objects we are now using value objects to transfer info from the service layer to Wicket. However we now end up with an explosion of almost the same objects : e.g. Answer (mapped entity saved in hibernate) AnswerVO (immutable value object) AnswerModel (A mutable bean in the session domain) IModel wrapped Wicket Model and usually this gets wrapped in a CompoundPropertyModel This plumbing becomes exponentially worse when collections to other objects are involved in the objects. There has to be a better way to organize this. Can anyone share tips to make this less onerous? Maybe make the value objects mutable so we can remove the need for a seaprate backing bean in Wicket? Use the entity beans but absolutely make dead-certain they are detached from hibernate. (easier said than done)? Some other tricks or patterns?

  • Not loading associations without proxies in NHibernate

    - by Alice
    I don't like the idea of proxy and lazy loading. I don't need that. I want pure POCO. And I want to control loading associations explicitly when I need. Here is entity public class Post { public long Id { get; set; } public long OwnerId { get; set; } public string Content { get; set; } public User Owner { get; set; } } and mapping <class name="Post"> <id name="Id" /> <property name="OwnerId" /> <property name="Content" /> <many-to-one name="Owner" column="OwnerId" /> </class> However if I specify lazy="false" in the mapping, Owner is always eagerly fetched. I can't remove many-to-one mapping because that also disables explicit loading or a query like from x in session.Query<Comment>() where x.Owner.Title == "hello" select x; I specified lazy="true" and set use_proxy_validator property to false. But that also eager loads Owner. Is there any way to load only Post entity?

  • Bizarre Bug with our Rails app in IE

    - by Callmeed
    We're experiencing a really bizarre bug in our Rails 2.3.4 app. This bug only happens in Internet Explorer (7 and 8). Here's what happens: A new customer creates an account at https://domain.com/signup/free (notice no subdomain) Their account is identified by a subdomain like "example.domain.com" After signing up, they get a welcome screen with a link to their account's home page They follow the link, then click the "log in" button and attempt to login Even though they provide valid credentials, the app redirects back to their account's root url ... they can never reach their admin area The only way they can login (on IE) is by quitting and re-opening IE ... then it works fine ... Something with their initial session is preventing them from logging in. If it matters, we are using restful_authentication and the ssl_requirement plugin ... I'm not sure if one or both of those has a problem with IE but we are stumped here. Also, I've read IE has an issue with subdomains that contain underscores ... this isn't what's going on.

  • Rails ActionCaching with Memcached fragment hit but action gets called anyway

    - by baldtrol
    Hi stackoverflow. I'm running into something strange. I'm using memcached with a caches_action setup. I'm doing this in 4 different controllers. In two of them, it works flawlessly (so far), though admittedly those two controllers are less complicated than the two in which it doesn't seem to work. I'm doing something like this: caches_action :index, :expires_in => 6.hours, :cache_path => Proc.new {|controller| controller.send(:generate_cache_path) }, :layout => false, :if => Proc.new { |c| c.request.format.js? } The intention behind the above is to cache some results that are dependent on the params. my :generate_cache_path method just takes into account some params and session vars and creates a unique key for memcached. I can see in memcached -vv that this is working. What's weird is that I get my request from the rails app for a given key, and I see memcached (with -vv) get the request and send back the response. But then my action runs anyway, and a new value is then set for the same key, even when all the same params are given. I can watch it happen. In the controllers where everything is working, the request is made for the fragment, it gets it, and the action in the controller is halted, and the fragment is passed back. These lines come from the exact same request: Cached fragment hit: views/items/?page=1&rp=10&srtn=created_at&srto=DESC.js And then: Cached fragment miss: views/items/?page=1&rp=10&srtn=created_at&srto=DESC.js I don't know what to make of it, or if I'm doing something stupid. Any help or ideas where I could start looking for trouble would be greatly appreciated.

  • beforeClose not working in jGrowl?

    - by sparkymark75
    I have the following code which pulls json data from an ASP.NET page and displays these as notifications. The code will also take a note of what's been pulled through and store it in an array to prevent it being shown again in the same session. I'm now trying to implement functionality so that when the user closes a message, it's ID is recorded in a cookie to prevent it ever being shown again. To do this, I'm trying to write to the cookie when the beforeClose event fires. Everything else works fine apart from the saving to a cookie bit. Is there something wrong with my code that I'm missing? var alreadyGrowled = new Array(); var noteCookie = $.cookie("notificationsViewed"); if (noteCookie != null) { alreadyGrowled = noteCookie.split(","); } function growlCheckNew() { $.getJSON('getNotifications.aspx', function(data) { $(data).each(function(entryIndex, entry) { var newMessage = true; $(alreadyGrowled).each(function(index, msg_id) { if (entry['ID'] == msg_id) { newMessage = false; } }); if (newMessage == true) { $.jGrowl(entry['Message'], { sticky: true, header: entry['Title'], beforeClose: function(e, m) { $.cookie("notificationsViewed", entry['ID']); } }); } alreadyGrowled.push(entry['ID']); }); }); }

  • Hibernate does not allow an embedded object with an int field to be null?

    - by Jason Novak
    Hibernate does not allow me to persist an object that contains an null embedded object with an integer field. For example, if I have a class called Thing that looks like this @Entity public class Thing { @Id public String id; public Part part; } where Part is an embeddable class that looks like this @Embeddable public class Part { public String a; public int b; } then trying to persist a Thing object with a null Part causes Hibernate to throw an Exception. In particular, this code Thing th = new Thing(); th.id = "thing.1"; th.part = null; session.saveOrUpdate(th); causes Hibernate to throw this Exception org.hibernate.PropertyValueException: not-null property references a null or transient value: com.ace.moab.api.jobs.Thing.part My guess is that this is happening because Part is an embedded class and so Part.a and Part.b are simply columns in the Thing database table. Since the Thing.part is null Hibernate wants to set the Part.a and Part.b column values to null for the row for thing.1. However, Part.b is an integer and Hibernate will not allow integer columns in the database to be null. This is what causes the Exception, right? So I am looking for workarounds for this problem. I noticed making Part.b an Integer instead of an int seems to work, but for reasons I won't bore you with this is not a good option for us. Thanks!

  • YQL + PHP : how to make a facebook login

    - by Jonathan
    Hi! I was reading some stuff about the YQL api that Yahoo! has provided, I am not sure, but it appears to be a collection of lots of third party api into one common language, right? what I don't get is how to make the facebook login through it so I can get the user profile data... My project is to add a facebook(and other social networks) form login, because the website won't have his own login, people will have to use a social network to link in. Then I thought the YQL would help me out with this task so I wouldn't have to develop lots of functions to each one of the networks. Reading this http://developer.yahoo.com/yql/guide/yql-code-examples.html#sdk_yql, I understood how to make a Yahoo login so I can access some private data, but couldn't find how I could do it with facebook and others So my question... Can YQL help me with this? Can you give me a simple example of a facebook session using it within PHP? Are there alternatives to aid me in this task? thanks, Jonathan

  • Open an Emacs buffer when a command tries to open an editor in shell-mode

    - by Chris Conway
    I like to use Emacs' shell mode, but it has a few deficiencies. One of those is that it's not smart enough to open a new buffer when a shell command tries to invoke an editor. For example with the environment variable VISUAL set to vim I get the following from svn propedit: $ svn propedit svn:externals . "svn-prop.tmp" 2L, 149C[1;1H ~ [4;1H~ [5;1H~ [6;1H~ [7;1H~ ... (It may be hard to tell from the representation, but it's a horrible, ugly mess.) With VISUAL set to "emacs -nw", I get $ svn propedit svn:externals . emacs: Terminal type "dumb" is not powerful enough to run Emacs. It lacks the ability to position the cursor. If that is not the actual type of terminal you have, use the Bourne shell command `TERM=... export TERM' (C-shell: `setenv TERM ...') to specify the correct type. It may be necessary to do `unset TERMINFO' (C-shell: `unsetenv TERMINFO') as well.svn: system('emacs -nw svn-prop.tmp') returned 256 (It works with VISUAL set to just emacs, but only from inside an Emacs X window, not inside a terminal session.) Is there a way to get shell mode to do the right thing here and open up a new buffer on behalf of the command line process?

  • ASP Function that returns result from stored procedures

    - by Brad
    I am working on a project that requires me to hop into to separate DB's. So I have figured that I need to have multiple functions inside of my VB page. The only problem I am having,is I am not to sure how to get this all accomplished. So far I have figured out the overall structure, just need help implementing that structure. Here is my idea: The main Function would call two other functions. We can Call them Sub Function 1 and Sub Function 2. So, the main Function takes the saved sessions information for the E-mail address and dumps in into Sub Function 1. It needs to open up a new connection to the db/stored procedure and RUN the following procedure and then return the result. Here is the stored procedure and what i think is correct. CREATE PROCEDURE WEB_User ( @EMAIL_ADDRESS varchar(80) = [EMAIL_ADDRESS] ) AS SELECT MEMBER_NUMBER FROM WEB_LOGIN WHERE EMAIL_ADDRESS = @EMAIL_ADDRESS So my question is, what is the function suppose to look like? how do I send the session information to the procedure? and finally, how do I return the stored procedure results and push back into the main function so it can be carried into sub function 2? Thank you in advance for your help... I really appreciate it!

  • sorting a gridview alphabetically when columns are codes

    - by nat
    hi there i have a gridview populated by a Web Service search function. some of the columns in the grid are templatefields, because the values coming back from the search (in a datatable) are ids - i then use these ids to lookup the values when the rowdatabound event is triggered and populate a label or some such. this means that my sorting function for these id/lookup columns sorts by the ids rather than the textual value that i have looked up and actually populated the grid with (although i do put the ids in the grids datakeys). what i want to do is top be able to sort by the looked up textual value rather than the codes for these particular columns. what i was going to do to get around this was to when the datatable comes back from the search, adding more columns the textual values and doing all the looking up then, thus being able to sort directly from the manually added columns. is there another way to do this? as that approach seems like a bit of a bodge. although i guess it does remove having to do the looking up in the rowdatabound event.... my sorting function works by sticking the datatable in the session and on each bind grabbing the sort column and binding the gridview to a DataView with the sort attribute set to the column - and the direction. thanks nat
