  • How do I get a scalar value from a stored proc using Nettiers

    - by Micah
    I have a really simple stored procedure that looks like this: CREATE PROCEDURE _Visitor_GetVisitorIDByVisitorGUID ( @VisitorGUID AS UNIQUEIDENTIFIER ) AS DECLARE @VisitorID AS bigint SELECT @VisitorID = VisitorID FROM dbo.Visitor WHERE VisitorGUID = @VisitorGUID --Here's what I've tried RETURN @VisitorID 'Returns an IDataReader SELECT @VisitorID 'Returns an IDataReader --I've also set it up with a single output --parameter, but that means I need to pass --the long in by ref and that's hideous to me I'm trying to get nettiers to generate a method with this signature: public long VisitorService.GetVisitorIDByVisitorGUID(GUID visitorGUID); Basically I want Nettiers to call ExecuteScalar instead of ExecuteReader. What am I doing wrong?

  • How- XLST Transformation

    - by Yuan Ray
    Just wanted to ask on how to get the author names in the given xml sample below and put an attribut of eq="yes". EQ means Equal Contributors. This is the XML. <ArticleFootnote Type="Misc"> <Para>John Doe and Jane Doe are equal contributors.</Para> </ArticleFootnote> This should be the output in other form of XML. <AuthorGroups> <Authors eq="yes">John Doe</Authors> <Authors eq="yes">Jane Doe</Authors> </AuthorGroups> Assuming that JOhn Doe and Jane Doe are already defined in the list of authors but after the transformation, author tag should have the attribute eq="yes". Please help as I don't know much writing in xlst. Thanks in advance.

  • Month to Date in SQL Server 2008

    - by Aaron Smith
    Hopefully this will be an easy one to answer. I am working on a table that requires MTD data. One of our SQL guys told me to use MONTH (@monthtodate)= 11 Where @monthtodate is set to GetDate() in the parameter list in SQL Server Management Studio. So in "theory", he says, it should select the month (11) and then get today and return all the requested data in between those two dates. But I'm thinking this isn't correct. In looking at my data I'm starting to think that It's just returning data for the whole month of November instead of just MTD. I guess, technically, anything that has 0 won't be calculated. However that just means it's poorly written code correct? In your opinions, would this be the better way to return MTD data: production_date <= @today and Production_Date >= DATEADD(mm, DATEDIFF(mm, 0, @today), 0) Thanks in advance everyone!

  • Integrating 3rd-party forum software to member-based website

    - by john
    When using some existing forum software in a larger web-site, how easy is it to: 1)Make your site's login functionality log the user into the forum 2)Make your site's registration functionality create forum login data I suppose in a way it might be easier to ONLY use the forum's database for maintaining users, but that means trusting it with sensitive data. I'm planning an integration between an existing bespoke desktop app and a new bespoke web-site which should include forums. I don't know which forums will be used but I know the new web functionality won't be PHP-based. I figure that's not a big deal but I'm wondering if forums typically allow configuration of where they look for login data, to avoid duplicating this data into my DB and the forum DB.

  • MySQL: Changing order of auto-incremented primary keys?

    - by Tom
    Hi, I have a table with a auto-incremented primary key: user_id. For a currently theoretical reason, I might need to change a user_id to be something else than it was when originally created through auto-incrementation. This means there's a possibility that the keys will not be in incremental order anymore: PK: 1 2 3 952 // changed key 4 5 6 7 I'm wondering whether this will cause problems, and whether MySQL reads something special to the incremental order of the keys, given that they should have come to existence in incremental order (which persists even when some rows are deleted). Assuming there are no associated foreignkey issues, or that these are under control, is there a problem with "messing with" the order of MySQL's autoincremented keys? Thank you.

  • Copying a massive databse for local ruby on rails development?

    - by tesmar
    Hi guys, There is a massive database (GB) that I am working with now and all of the previous development has been done on a slicehost slice. I am trying to get ready for more developers to come in and work so I need each person to be able to setup his own machine for development, which means potentially copying this database. Selecting only the first X rows in each table to cut size could be problematic for data consistency. Is there any way around this, or is a 1 hour download for each developer going to be necessary? And beyond that, what if I need to copy the production DB down for dev purposes in the future? Sincerely, Tyler

  • C#: Making sure parameter has attribute

    - by slayerIQ
    I have an attribute lets call it SomeAttribute and a class i need to make sure the class is passed a type which has SomeAttribute. So this is how i do it now: public class Test() { public Test(SomeType obj) { if(!obj.GetType().IsDefined(typeof(SomeAttribute), false)) { throw new ArgumentException("Errormessage"); } } } But this means that i don't get any errors at compile time but somewhere at runtime, if obj does not have the attribute. Is there a way to specify in the method declaration that the parameter must have some attribute ? So i get errors i compile time when using the wrong parameters.

  • Sending changing params through periodically_call_remote

    - by seaneshbaugh
    I'm using periodically_call_remote to update a portion of a page that contains a list of objects. I send along with the url a param containing the created_at date for the most recent object in the database. The action that is called then get all the objects that have been created since then and renders a partial which displays them at the top of the list. The problem is that I can't seem to figure out how to make it so that the next time periodically_call_remote triggers it sends along the created_at date for the new most recent object (if there is one). I tried putting the periodically_call_remote inside the partial that is being rendered but that caused all sorts of problems (http://www.ruby-forum.com/topic/101614 explains why you shouldn't do that). Is there some way I can make periodically_call_remote send along a new param each time it's called? As it stands right now it just sends the same one over and over which means that new objects get rendered more than once.

  • Create slide-in notifications à la Outlook in Windows with .NET

    - by Draak
    I am using .NET and am creating a desktop app/service that will display notifications in the corner of my Desktop when certain events are triggered. I don't want to use a regular Message Box b/c that would be too intrusive. The notifications would slide into view and then fade out after a few seconds. I am thinking of something that will act very much like the Outlook alerts that one gets when a new message arrives. The question is: Should I use WPF for this? I've never done anything with WPF but will happily try it if that's best means to the end. Is there a way to accomplish this with regular .NET libraries?

  • Does replacing statements by expressions using the C++ comma operator could allow more compiler opti

    - by Gabriel Cuvillier
    The C++ comma operator is used to chain individual expressions, yielding the value of the last executed expression as the result. For example the skeleton code (6 statements, 6 expressions): step1; step2; if (condition) step3; return step4; else return step5; May be rewritten to: (1 statement, 6 expressions) return step1, step2, condition? step3, step4 : step5; I noticed that it is not possible to perform step-by-step debugging of such code, as the expression chain seems to be executed as a whole. Does it means that the compiler is able to perform special optimizations which are not possible with the traditional statement approach (specially if the steps are const or inline)? Note: I'm not talking about the coding style merit of that way of expressing sequence of expressions! Just about the possible optimisations allowed by replacing statements by expressions.

  • C/C++ - Convert 24-bit signed integer to float

    - by e-t172
    I'm programming in C++. I need to convert a 24-bit signed integer (stored in a 3-byte array) to float (normalizing to [-1.0,1.0]). The platform is MSVC++ on x86 (which means the input is little-endian). I tried this: float convert(const unsigned char* src) { int i = src[2]; i = (i << 8) | src[1]; i = (i << 8) | src[0]; const float Q = 2.0 / ((1 << 24) - 1.0); return (i + 0.5) * Q; } I'm not entirely sure, but it seems the results I'm getting from this code are incorrect. So, is my code wrong and if so, why?

  • Is a class that is hard to unit test badly designed?

    - by Extrakun
    I am now doing unit testing on an application which was written over the year, before I started to do unit-testing diligently. I realized that the classes I wrote are hard to unit test, for the following reasons: Relies on loading data from database. Which means I have to setup a row in the table just to run the unit test (and I am not testing database capabilities). Requires a lot of other external classes just to get the class I am testing to its initial state. On the whole, there don't seem to be anything wrong with the design except that it is too tightly coupled (which by itself is a bad thing). I figure that if I have written automated test cases with each of the class, hence ensuring that I don't heap extra dependencies or coupling for the class to work, the class might be better designed. Does this reason holds water? What are your experiences?

  • Are entities cached in jpa by default ?

    - by Nitesh Panchal
    Hello, I add entity to my database and it works fine. But when i retrieve the List, i get the old entity, the new entities i add are not shown until i undeploy the application and redeploy it again. This means are my entities cached by default? But, I haven't made any settings for caching entities in my persistence.xml or any such file. I have even tried calling flush(), refresh() and merge(). But still it shows the old entities only. Am i missing something? Please help me.

  • What ASP.NET MVC project files should I not add to Subversion

    - by Dan
    this is likely a naive question, but I want to do this right the first time. I have a MVC solution which has the following: Data project - C# Services project - C# MVC Web Project - ASP.NET MVC Test Project Currently, I am using the MVC2 source as a means to debug my own code. I do not plan on checking that in, but I realize once I go back to the MVC2 DLL, my solution will change. I'm pretty sure I just shouldn't check in stuff that changes with each build: the bin folder on the Web project, for example. Is there a list of what not to commit to source control? :)

  • ASP.Net: Finding the cause of OutOfMemoryExpcetions

    - by Keith Bloom
    I trying to track down the cause of an OutOfMemory for a website. This site has ~12,000 .aspx pages and the last time it crashed I captured a memory dump using adplus. After some investigation I found a lot of heap fragmentation, there are around 100MB of Free blocks which can't be assigned. Digging deeper one of the Large Object Heaps is fragmented and the causes seems to be String interning as described [here][1] Could this be caused by the number of pages in the site? As they are all compiled they sit in memory and by looking at the dump they are interned and PINNED which I think means they stick around for a while. I would find this odd as there are many sites with more pages, but dynamic compilation could account for the growth in memory. What other methods are there for finding the cause of the memory leak? I have tried to capture a dump using adplus in hang mode but this fails and the IIS worker process get recycled. [1]: • http://stackoverflow.com/questions/686950/large-object-heap-fragmentation

  • Network Security and Encryption explained in laymen terms

    - by Ehrann Mehdan
    Although I might pretend very well that I known a thing about networks or security and it might help me pass an interview, or fix a bug, I don't really feel I'm fooling anyone. I'm looking for a laymen terms explanation of nowadays network security concepts and solutions. The information is scattered around and I didn't find a resource for "dummies" like me (e.g experienced Java developers that can speak the jargon but have no real clue what it means) Topics I have a weak notion about and want to understand better as a Java developer PGP Public / Private keys RSA / DES SSL and 2 way SSL (keystore / trustore) Protecting against Man in the middle fraud Digital Signature and Certificates Is there a resource out there that really explains it in a way that doesn't require a Cisco certificate / Linux lingo / know what is subnet masking or other plumbing skills?

  • What policies are standard for programmers?

    - by Shehket's Apprentice
    My office is about has proposed implementing some extremely strict (I would consider them draconian) policies regarding programmers, and our access due to security concerns (note, we have never had a security breach). While I can theoretically get used to them, I'd like to ask about what is considered good security policy for programmers, specifically in the area of access policies, and what is too much? Any answers to this question are greatly appreciated as they directly relate to my ability to write code, and I can't find anything so far on Google. Edit: Most of the security policies that concern me are about access to my machine and to the code. According to these proposed policies, I'd need management approval to access either, which means that I'd be forced to get management to unlock my computer anytime I leave my desk as my computer is always locked when I'm not at my desk.

  • HTML form requirements specification

    - by Peder
    I am building a framework that will validate forms both client-side (javascript) and server-side based on a form requirements specification written in json. The purpose is to get rid of logically equivalent code on the server and client to make the code more maintainable, faster to write, and less buggy. The specification format may look something like: { '&lt;field_name>' : ['&lt;validation_function>', 'req', ['&lt;requirement>', &lt;param>], ...], ... } ( the requirement list is ordered so that the user can get most basic error messages first, the 'req' requirement must come first if it exists and means that the field is required) e.g.) { 'name' : ['string', 'req', ['min',6], ['max',150], ['match', /^[\sa-z0-9ÅÄÖåäö&]$/i], ['not_match', /^tmp_/]], 'email' : ['email', 'req'], 'email_confirm' : ['same_as', 'email'], 'password' : ['string', 'req', ['min', 6], ['max', 64], ['match', /^[a-z0-9\!@#\$%^&*_+.]$/i] ], } Does anyone know of a similar technology? I think the Rails validation framework solves the problem on the wrong level because I have found that forms often operate on more than one model.

  • How to implement Gradient Opacity (Mask) using html css javascript

    - by brz dot net
    I have to show 25% right screen in such way that the text looks appeared from right. For this I need to set opacity from 0 to 100 at 25% right side screen means rightmost opacity would be 0 and at 75% the opacity would be 100. For this, I took a Div and set opacity but It looks bad because of border. I need to gray out text. It looks a block. Let me know how I can implement cross browser compatible gradient opacity mask for right screen text. What is the best way to do this?

  • how can c# help in drawing using memory layers concept?

    - by moon
    hello all i am facing problem in drawing dynamically in a picture box. i works very good when the drawing objects are few but as the drawing objects increases the response time of my GUI is getting worse and worse, my GUI works very well up to 90 drawing objects but i have to support more than 1000 so this technique didn't work for me. know i have decided to adopt layers mechanism, i mean i will draw different layers of drawing in memory and then XOR them to load the final image to my display. the question is "i Can play directly with memory do draw layers using C# (Examples needed?)" other ideas are also appreciated, (Drawing objects means the shapes line,circles etc. that i have to draw on my GUI) thanx in advance

  • glDrawElements allocating memory and not releasing it

    - by Joshua Weinberg
    Using OpenGLES 1.1 on the iPhone 3G (device, not simulator), I do normal drawing fun. But at points during the run of the application I get giant memory spikes, after a lot of digging with instruments I have found that it is glDrawElements that is grabbing the memory. The buffer being allocated is 4 meg, which to me means its loading a texture into RAM, which I guess could be valid, but its never releasing this buffer, and is allocating multiple of them. How do I make sure that these buffers that GL is creating get destroyed, instead of just hanging around?

  • how to check an ANTLR token is only used once or less in the parser

    - by Simon Kenyon Shepard
    In Antlr, if I have a rule for example: someRule : TOKENA TOKENB; it would accept : "tokena tokenb" if I would like TOKENA to be optional, I can say, someRule : TOKENA* TOKENB; then I can have : "tokena tokenb" or "tokenb" or "tokena tokena tokenb" but this also means it can be repeated more that once. Is there anyway I can say this token can be there 1 or less times but not more than one? so it would accept: "tokena tokenb" or "tokenb" BUT NOT "tokena tokena tokenb"? Many thanks

  • How do I best run a search on Date when it is not a :has_many association?

    - by Angela
    I have a number of activities that have a calculated scheduled date. The activities, for example, Email, have a email.days method which is the days from a Contact.start_date on which it should be sent. This means contact.start_date + email.days yields a date on which email is sent to contact. I would like to use link_to around the date, so I can see all the emails and associated contacts that are to be scheduled on that date. However, this "date" is not an attribute or an associate, so I'm not linking to a model's view. It's calculated. So: 1) What should the actual "format" of the date that gets passed in the URl be? What is the method to do the consistent conversion? 2) How do I (find) all instances, because this "date" is not an actual attribute, is it a calculated value which changes depending on the two associated models of Contact and Email. Thanks.

  • Allow for modular development while still running in same JVM?

    - by Marcus
    Our current app runs in a single JVM. We are now splitting up the app into separate logical services where each service runs in its own JVM. The split is being done to allow a single service to be modified and deployed without impacting the entire system. This reduces the need to QA the entire system - just need to QA the interaction with the service being changed. For inter service communication we use a combination of REST, an MQ system bus, and database views. What I don't like about this: REST means we have to marshal data to/from XML DB views couple the systems together which defeats the whole concept of separate services MQ / system bus is added complexity There is inevitably some code duplication between services You have set up n JBoss server configurations, we have to do n number of deployments, n number of set up scripts, etc, etc. Is there a better way to structure an internal application to allow modular development and deployment while allowing the app to run in a single JVM (and achieving the associated benefits)?
