  • asp.net mvc model - my own database

    - by progtick
    The tutorials I have come across usually let you create a dababase from scratch creating a .mdf file or something and so on. However, what if I already have a SQL Server Express set up with the needed database? How do I tell my model to use that database? Right now, all my model contains is basically some classes that execute stored procedure on my own database and return manupulated data. Should I leave it as it is? What are the benefits of going through the full-fledged model approach that tutorials demonstrate?

  • how to access jquery internal data?

    - by Unknown
    As you may or may not be aware as of jQuery 1.7 the whole event system was rewritten from the ground up. The codebase is much faster and with the new .on() method there is a lot of uniformity to wiring up event handlers. One used to be able to access the internal events data and investiate what events are registered on any given element, but recently this internal information has been hidden based on the following scenario... It seems that the "private" data is ALWAYS stored on the .data(jQuery.expando) - For "objects" where the deletion of the object should also delete its caches this makes some sense. In the realm of nodes however, I think we should store these "private" members in a separate (private) cache so that they don't pollute the object returned by $.fn.data()" Although I agree with the above change to hide the internal data, I have found having access to this information can be helpful for debugging and unit testing. What was the new way of getting the internal jquery event object in jQuery 1.7?

  • Is there an open source repository for SQL code?

    - by morpheous
    I find myself writing SQL code (queries or stored procs) to solve problems that can definitely be defined as 'patterns' that occur frequently in business. Rather than having to wrack my brain each time I encounter a new problem (which must have been solved a countless times by other coders/db analysts, I wondered if there was a repository I could go to check out (peer reviewed) code - and maybe add my two pence every now and then. I know different db vendors tend to write slightly variant forms of SQL - but there could still be a repository with ANSI stuff and proprietary stuff. Hopefully, such a site would encourage more people to write standardized SQL. Is there such a site?. If no - why not? (would anyone else be interested in such a site?) If such a site exists, please provide link(s), as Google is not finding anything remotely useful.

  • Cocoa Interface Builder object initialization

    - by Stanley
    Base on the documentation and sample code that I have gone through, I got an impression that when a class defined in xcode is read into and configured in Interface Builder, an object based on the class is effectively created and stored in an xib or nib file. So the object is ready to be used when the corresponding application is launched. Alternatively, for classes that have not been handled by Interface Builder, code such as the "new" statements have to be written in xcode explicitly in order for the associated objects to be created and used. It will be very nice to have people who are more knowledgable than me to confirm or to correct my very naive understanding of Interface Builder ...

  • Why does the infobox in my MSN Map not close?

    - by meder
    I'm having a bit of trouble with this map, invoked by the "View our interactive map" button in the middle of the content area. If you double click a point such as 8 which causes a zoom and then afterwards it causes the info box to appear, the hide logic is wrong. If you try to close the x, it will fail. This is probably because the user clicked too fast and the map thinks its in zoom mode when infact it should be in info box mode. Has anyone ran into this issue before? Looks like I have to mess around with window.ero.hide and some other functions.. because map.HideInfoBox doesn't hide the map. EDIT: The script used is here. I did not code it, but the relevant bit has: onclick="EnableEroHide();map.HideInfoBox();changePin();return false;" The map.HideInfoBox() should hide the info box.

  • C string program

    - by mrblippy
    Hi, i have been given a task to do ar school that must read three strings in, store the third string in dynamically allocated memory and print out the last 4 letters of the first word alphabetically. Here is the program i have so far but the strings are all stored in different variables, making them hard to sort. if anyone could give me a hand and help me finish this program i would be very grateful. thanks #include <stdio.h> #include <stdlib.h> #include <string.h> int main() { char word1[101]; char word2[101]; char* word3; char buffer[101]; scanf("%s", word1); scanf("%s", word2); scanf("%s", buffer); word3 = (char *) malloc(strlen(buffer)+1); strcpy(word3, buffer); return 0; }

  • From .NET TO SQL

    - by Berlioz
    How do you pass a value from your DAL to your sproc so that the ISNULL function will do it's job. Particularly the DATE value coming from my .NET assembly. In T-SQL an INSERT STMNT and in the VALUES clause, the line of interest goes like this; ISNULL(@myparm_forcolumn9, @myparm_forcolumn9). What value do I pass from .NET to make this line in my sproc work universally, so I don't have to write a millions INSERT SPROCS for every combination of columns??? I just want to write one stored procedure(sproc) that will handle all INSERTS in my universe.

  • Possible to convert list of #defines into strings (C++)

    - by brandonC
    Suppose I have a list of #defines in a header file for an external library. These #defines represent error codes returned from functions. I want to write a conversion function that can take as an input an error code and return as an output a string literal representing the actual #define name. As an example, if I have #define NO_ERROR 0 #define ONE_KIND_OF_ERROR 1 #define ANOTHER_KIND_OF_ERROR 2 I would like a function to be able to called like int errorCode = doSomeLibraryFunction(); if (errorCode) writeToLog(convertToString(errorCode)); And have convertToString() be able to auto-convert that error code without being a giant switch-case looking like const char* convertToString(int errorCode) { switch (errorCode) { case NO_ERROR: return "NO_ERROR"; case ONE_KIND_OF_ERROR: return "ONE_KIND_OF_ERROR"; ... ... ... I have a feeling that if this is possible, it would be possible using templates and metaprogramming, but that would only work the error codes were actually a type and not a bunch of processor macros. Thanks

  • Is there any way to retrieve a float from a varargs function's parameters?

    - by Jared P
    If the function was defined with a prototype which explicitly stated the types of the parameters, eg. void somefunc(int arg1, float arg2); but is implemented as void somefunc(int arg1, ...) { ... } is it possible to use va_arg to retrieve a float? It's normally prevented from doing this because varargs functions have implicit type promotions, like float to double, so trying to retrieve an unpromoted type is unsupported, even though the function is being called with the unpromoted type do to the more specific function prototype. The reason for this is to retrieve arguments of different types at runtime, as part of an obj-c interpreter, where one function will be reused for all different types of methods. This would be best as architecture independent (so that if nothing else the same code works on simulator and on device), although if there is no way to do this then device specific fixes will be accepted.

  • Architecture for analysing search result impressions/clicks to improve future searches

    - by Hais
    We have a large database of items (10m+) stored in MySQL and intend to implement search on metadata on these items, taking advantage of something like Sphinx. The dataset will be changing slightly on a daily basis so Sphinx will be re-indexing daily. However we want the algorithm to self-learn and improve search results by analysing impression and click data so that we provide better results for our customers on that search term, and possibly other similar search terms too. I've been reading up on Hadoop and it seems like it has the potential to crunch all this data, although I'm still unsure how to approach it. Amazon has tutorials for compiling impression vs click data using MapReduce but I can't see how to get this data in a useable format. My idea is that when a search term comes in I query Sphinx to get all the matching items from the dataset, then query the analytics (compiled on an hourly basis or similar) so that we know the most popular items for that search term, then cache the final results using something like Memcached, Membase or similar. Am I along the right lines here?

  • Session Timeout and page response time

    - by Johnny5
    Hi, I'm load testing an asp.net app. The load test is simulating 500 user doing searchs on the site and browsing the results. I'm observing that the more I reduce the session timeout limit (in web.config) the better the page response time. For exemple, with a timeout at 10 minutes, I got an average response time of 8.35 seconds. With a timout at 3 minutes, the average response time for the same page is 3,98 seconds. The session in stored "InProc". I supposed the memory used by the "no more used but still actives" sessions may be in cause. But, even if there is more memory used when the timeout is at 10, there is still plenty of memory available (about 2.7Gb). Any ideas?

  • Problem with session based login after moving relevent files to site root

    - by YsoL8
    Hello I have a site which I have been testing in a sub-folder of my clients site-root. I had no log in problems during testing, but then I moved the new site files from a sub-directory to the main site root, and now I'm losing my logged in state after almost every page refresh in secure areas. I am running a $_session based login system that refreshes the session id on every page load, with a comparison value stored in the MySQL database. Does anyone have suggestions for what could be causing this problem?

  • Multiple user database design

    - by dieguitoweb
    I have to develop a basic social network for an academic purpose; but I need some tips for the users management.. The users are subdivided into 3 groups with different privilege: admins,analysts and standards users. For every user should be stored into the database the following information: name,lastname,e-mail,age,password. I'm not quite sure how I should design the database between theese two solutions: 1)one table called 'users' with the 'role' attribute that explain what a user can do and what can't do, and the permissions are managed via php 2)every application user is a database user created with the query 'CREATE ROLE' (It's a postgres database) and he has permissions on some tables granted with the 'GRANT' statement You should take into account that the project is for a database exam.. thanks

  • How to get the action argument of a wp-login.php request?

    - by Bruno De Barros
    I am trying to integrate my custom user system with Wordpress, and I have recently asked a question on how to redirect requests to wp-login.php to my own login/registration page, but as I was working on the pluggable functions, I realized that requests to wp-login.php can either be for login, registration, or log out. This is set in the action argument that's made in the request. What I am trying to figure out is how to get this action argument, so I can redirect the request to my custom pages. Is there any way of doing this? Thank you in advance.

  • NotificationCenter Widget Failed To Use CoreLocation

    - by James Ye
    I'm writing a notification center widget, and it had to use location information. In normal apps I use CoreLocation and it works fine. But in my widget, I tried to locationServicesEnabled but it didn't go to the callback functions, and the authorizationStatus is always kCLAuthorizationStatusNotDetermined, and the authorize setting didn't show up in Setting - location service. I already set the delegate to the class. The system's Yahoo weather widget can auto locating and it uses CoreLocation too, so the widget do have ability to use location service. Why CoreLocation doesn't work on my widget?

  • How can I set breakpoints in an external JS script in Firebug

    - by Manu
    I can easily set breakpoints in embedded JS functions, but I don't see any way of accessing extarnal JS scripts via Firebug unless I happen to enter them during a debug session. Is there a way to do this w/o having to 'explore' my way into the script? @Jason: This is a good point, but in my case I do not have easy access to the script. I am specifically talking about the client scripts which are invoked by the ASP.Net Validators that I would like to debug. I can access them during a debug session through entering the function calls, but I could not find a way to access them directly.

  • Secure xml messages being read from database into app.

    - by scope-creep
    I have an app that reads xml from a database using NHibernate Dal. The dal calls stored procedures to read and encapsulate the data from the schema into an xml message, wrap it up to a message and enqueue it on an internal queue for processing. I would to secure the channel from the database reads to the dequeue action. What would be the best way to do it. I was thinking of signing the xml using System.Security.Cryptography.Xml namespace, but is their any other techniques or approaches I need to know about? Any help would be appreciated. Bob.

  • WPF Datatemplate + ItemsControl each item uses > 1 MB Memory?

    - by Matt H.
    Does that sound right to anyone???? I have an ItemsControl that displays data from a custom object that implements iNotifyPropertyChanged. The DataTemplate consists of: Border 3 buttons 5 textboxes An ellipse A Bindable RichTextBox (custom class that inherits from RichTextBox... so I could make Document a dependency property (to support binding)) Several grids and stackpanels for layout It uses: Styles (stored in a resource dictionary higher up the tree) Styles affect: colors, thicknesses, and text properties: which are data-bound to a "settings" class that implements iNotifyPropertyChanged, so the user can change display settings That's it! So what gives? I've also noticed that when I empty and remove the ItemsControl, memory isn't freed. over 5000 instances of "CommandBindingCollection" and "WeakReference" are CREATED (using ANTS profiler). And huge number of EffectiveValueEntry objects are created too. So really, what gives!!! :-) Thanks for your insight! Management needs this project soon but in its current state, it's unreleasable.

  • Lots of pointer casts in QGraphicsView framework and performance

    - by kleimola
    Since most of the convenience functions of QGraphicsScene and QGraphicsItem (such as items(), collidingItems(), childItems() etc.) return a QList you're forced to do lots of qgraphicsitem_cast or static_cast and QGraphicsItem::Type() checks to get hold of the actual items when you have lots of different type of items in the scene. I thought doing lots of subclass casts were not a desirable coding style, but I guess in this case there are no other viable way, or is there? QList<QGraphicsItem *> itemsHit = someItem->collidingItems(Qt::IntersectsItemShape); foreach (QGraphicsItem *item, itemsHit) { if (item->type() == QGraphicsEllipseItem::type()) { QGraphicsEllipseItem *ellipse = qgraphicsitem_cast<QGraphicsEllipseItem *>(item); // do something } else if (item->type() == MyItemSubclass::type()) { MyItemSubClass *myItem = qgraphicsitem_cast<MyItemSubClass *>(item); // do something } // etc } The above qgraphicsitem_cast could be replaced by static_cast since correct type is already verified. When doing lots of these all the time (very dynamic scene), will the numerous casting affect performance beyond the normal if-else evaluation?

  • Problem mapping data located in a NSMutableArray

    - by Graeme
    I have an NSMutableArray which contains some addresses which I need to map using Apple's MapKit SDK which I can't seem to get to load. The NSLog keeps telling me that the data source is (null) and a 0x0 error displays when I attempt to print out the array. Any ideas? The data is parsed and stored from another class, perhaps I'm not linking it across properly? The data is originally gathered from an RSS feed, bought into the app with an IMporter class, and then displayed in a table view. I want to be able to connect into that data with my mapping class, but am struggling to do so.
