• Seeking FOSS user admin code

  - by Mawg

  It must be a fairly standard wheel, so I'd rather not reinvent it. Create/modify/delete users. Ditto their passwords & maybe enforce password change every X days. Also, create groups, like "sales", "support", etc and add/remove users. The only unique part should be what they have permission to do (visit certain parts of the site after login, etc) And I'd like to store admin data in an ODBC compliant database (MySql to start with, but I may move on). Is this a new wheel? There doesn't seem to be much of anything on SourceForge, but if I could find something established and trusted I wouldn't even mind paying a few $100 as a trade of for the time needed to develop & test it.

• Creating a relative path to a Database in Asp.net for a library

  - by Greener

  In school I am part of a team of four working to create a GUI to translate the paper records of a made-up company and their functionality to a digital format. We're using an ASP.NET website for this purpose. Basically we use stored procedures and C# classes to represent the database. The folder we're using for the project contains the site and the libraries in separate folders. If I try to open the site from the folder containing both these elements the site will not run. I want to know if there is some way I can set up a relative path to the database in the Settings.Settings.cs file (or by some other means) of my libraries so I don't have to constantly change the database location for the connection string value every time we move the project. I suppose I should also mention that the database is in an App_Data folder.

• Command to surround a character with spaces in vim

  - by William Becker

  I am trying to use vim properly - to aid me I've mapped my arrow keys to "" so that I am forced to use {hjlk} to move around. This is causing me a problem when I want to just surround a character with spaces, eg: "2+3" is better formatted "2 + 3" Previously I would have put my cursor over the + and typed: i[space][arrow-right][space][Esc] That's 5 presses. To do this without the arrow I seem to need to put the cursor over the + and go: i[space][Esc]lli[space][Esc] That's 8 presses. I can convert the "li" into an "a" which reduces it to 7 presses: i[space][Esc]la[space][Esc] Short of writing this into a macro is there a better way of doing it? Is there some magic vim command which will allow me to do it in less than even 5 presses - and some way to generalise it so that I can do it to entire words or symbols, eg if I want to convert 3==4 to 3 == 4?

• iphone/ipad with 2 side by side tables

  - by jesse001

  I want to create a view with 2 tables side by side, where selecting the row on 1 table effects the content of the other and vice versa (not parent child). My problem is how to send the request. I started with a utility app using core data, and added 2 table view controllers. I added these to the main view nib and moved the tables to the view. One table controls a list from Core Data, then on selecting a row I want it to move to the other table which is based on a mutable array. On didselectrow I want to tell the other table to update, however I can only find samples that are parent/child so involves initializing. Does anyone know of a way to do this for an active view? Thanks heaps for your help.

• how do I integrate the aspnet_users table that comes with asp.net membership into my existing databa

  - by ooo

  i have a database that already has a users table COLUMNS: userID - int loginName - string First - string Last - string i just installed the asp.net membership table. Right now all of my tables are joined into my users table foreign keyed into the "userId" field How do i integrate asp.net_users table into my schema? here are the ideas i thought of: Add a membership_id field to my users table and on new inserts, include that new field in my users table. This seems like the cleanest way as i dont need to break any existing relationships. break all existing relationship and move all of the fields in my user table into the asp.net_users table. This seems like a pain but ultimately will lead to the most simple, normalized solution any thoughts?

• Send 404 when requesting index.php through .htaccess?

  - by Daniel

  I've recently refactored an existing CodeIgniter application to use url segments instead of query strings, and I'm using a rewriterule in htaccess to rewrite stuff to index.php: RewriteRule ^(.*)$ /index.php/$1 [L] My problem right now is that a lot of this website's pages are indexed by google with a link to index.php. Since I made the change to use url segments instead, I don't care about these google results anymore and I want to send a 404 (no need to use 301 Move permanently, there have been enough changes, it'll just have to recrawl everything). To get to the point: How do I redirect requests to /index.php?whatever to a 404 page? I was thinking of rewriting to a non-existent file that would cause apache to send a 404. Would this be an acceptable solution? How would the rewriterule for that look like? edit: Currently, existing google results will just cause the following error: An Error Was Encountered The URI you submitted has disallowed characters.

• Is the offical Sun Java EE tutorial the best way to learn how to make Java web apps?

  - by Nick

  I've been a web developer for almost a decade. I've mostly used classic ASP/JavaScript and I'd like to move into Java based apps. I have a decent understanding of Java itself (enough to know how to lookup what I don't know) and I spent some time doing minor work on a JSF/Spring/Hibernate app, but from what a trusted coworker told me, this application is the example of what not to do. I want to learn the really hardcore stuff (EJBs, HA Clustering, etc), but I know I have to walk before I can run. Is the Sun Tutorial the best place to start? Or is there an definitive book (like K&R for C or Gang of Four for design patterns) that I should buy?

• Excel VBA : Changing string in cells

  - by user1265125

  I have cells with data like these: ABCD123XYZ MPOP345MLU . . . . What I want to do is, to remove the 3rd and 4th character from all these cells, hence giving AB123XYZ MP345MLU How do I do this in VBA? I have no idea about this language, and if someone can guide me in the right direction, it'd be great :) I understand I have to: 1. Declare 2 string variables st1 and st2 2. Store data from cell A1 into the variable st1 3. Copy all but the 2nd and 3rd char into str2 4. Output Str2 into B1 5. Move to A2

• iPhone/iPad fatal error in C++ code produces no output in the log

  - by morgancodes

  I'm trying to move away from Objective-C to C++ for audio in my iPad programming, due to the a few reports I've heard of Objective-C selectors sometimes causing audio glitches. So I'm starting to use pure C++ files. When a fatal error happens in one of the C++ files, I get no output from the log. The app just crashes. For example, if I do this in my C++ file: env = new ADSR(); cout << "setting env to null\n"; env = NULL; env->setSustainLevel(1); cout << "called function on non-initialized env\n"; I get the following output: setting env to null After that, there's a method called on NULL, which apparently kills the app, but absolutely nothing to that effect is reported. What do I need to do to have useful information logged when there's an error in my C++ code?

• Component properties working at designt time but not runtime - ???

  - by delphi-rulez-2010

  I am creating a component that uses a collection and collection items of panels. I can't seem to get the colors to work at runtime, but yet they seem to work just fine at design time. You can download the component source code here: http://www.shaneholmes.net/pasfiles/ There is a Consoles (Tcollection) property, status colors property, and a Edit mode property Each console (TCollectionItem) has a status property when changed, the consoles property is changed based on the components StatusColors property. When the components EditMode property is set to true, you can move the panels around at runtime. Question: Why does the colors only work at designtime and not runtime. thanks

• Using Components.utils.import in a firefox extension

  - by jamesatha

  I am trying to create some global variables in a firefox extension. In my content folder, I have two javascript files: 1) Main JS file that holds the functions for the different events, etc 2) A file that stores only an object with the pieces of state I want to maintain. Also, I set the array EXPORTED_SYMBOLS. I am having issues with the following line found in my main JS file: Components.utils.import("resource:///globalVariables.js"); When it is at the top of the file, nothing seems to work. If I move it into the function where I need the variable, the rest of my code works, but the function with this line does nothing. Any advice that would help me with this problem would be great. Thanks

• Webservice for serial port devices

  - by camx

  Hi I want to create a remote webservice for an application that is now avaliable only localy. This application controlls three devices (each is controlled separately) connected on serial port. The problem is that I don't know how to take care of passing back information that a device return requested data. For example - I send move command to the motion device (which is very slow and can take a minute or more). Can I just set a big timeout on the client side (and server side) and return for example a true/false if operation is completed or is this a bad idea? Is SOAP with big timeouts ok? And the other question is if Mono on Linux (Ubuntu 9.10, Mono 2.4) is stable enought for making a web service or should I chose Java or some other language? I'm open for recommendations. Thanks for your help!

• Validating primitive types in ASP.NET MVC

  - by Alex

  I've implemented the following classes to validate data public abstract class Validated { public bool IsValid { get { return (GetRuleViolations().Count() == 0); } } public abstract IEnumerable<RuleViolation> GetRuleViolations(); } public partial class User: Validated { public override IEnumerable<RuleViolation> GetRuleViolations() { if (this.Age < 1) yield return new RuleViolation("Age can't be less than 1"); } } It works great! When the form is submitted I just do if (user.IsValid == false) blah... But I still need to validate that the Age is an integer int a = 0; if (!int.TryParse(age, out a)) { error = "Not integer"; // ... } How can I move this to my model?

• How can I tell if an ADODB::_RecordsetPtr has already been created?

  - by scottm

  I am trying to write a class that uses ADO to retrieve SQL records. The intent is for the class to maintain one private recordset an other methods move forward, retrieve fields, etc. This is a basic example of my class: class SqlADO { private: ADODB::_RecordsetPtr m_recordset; public: void Open(); //open the connection void Execute(const char* sql); // creates or replaces current recordset void Next(); //moves recordset cursor forward void Field(const char* fieldName); //retrieves field name from current record of the recordset }; My Questions: In the Execute method, how can I check to see that the recordset instance has been created (or do I need to) so that I can close it first? Do you know of any good ADO COM Interop references?

• How do I supply values to an referenced assembly without calling a method it explicitly?

  - by Rob

  Currently I have a static class that I use as my logging module. I’ve added the class to my visual studio solution. Within the class I’ve specified the name and location of the log file to use. Which lets me do stuff like this – which I like and want. Logger.Information(“Page_Load”,”controls loaded correctly”); I’d like to refactor the code and move the logging functionality into a separately compiled assembly, if I did this I would then need to pass in the log file name and location to save the files too. However I don’t want to have to supply this information every time I call the ‘Logging’ method, this would be bad... Logger.Informtaion(“Page_Load”,”controls loaded correctly”,”logfile.txt”,”c:\temp”); Is there any way I can supply this information without having to specify it within each page or via the method call.

• Correct way to protect a private API key when versioning a python application on a public git repo

  - by systempuntoout

  I would like to open-source a python project on Github but it contains an API key that should not be distributed. I guess there's something better than removing the key each time a "push" is committed to the repo. Imagine a simplified foomodule.py : import urllib2 API_KEY = 'XXXXXXXXX' urllib2.urlopen("http://example.com/foo?id=123%s" % API_KEY ).read() What i'm thinking is: Move the API_KEY in a second key.py module importing it on foomodule.py; i would then add key.py on .gitignore file. Same as 1 but using ConfigParser Do you know a good programmatic way to handle this scenario?

• Transferring ownership of an iPhone app on the app store

  - by kfitzpatrick

  My team and I have an app which we're going to be submitting to the store pretty soon, but we know that we'll be selling the app to another company in the near future. Does anyone have any experience with moving an app's ownership to another account? Specifically, when I sell an app to another company... ... how do we move the app to their account (what's the mechanism)? ... can my users still get updates (released by the new owner) without having to re-buy/re-download the app?

• Don't panic - there is time!

  - by ripper234

  If you're thinking of moving to Shapado right this instance, take a breath. Yes, I think it's the right move in the long run (be it three months or a year). However, take into consideration that the platform is still not ready. It has bugs and feature-requests that should be fixed. Until they are, you are better off staying with Stack Exchange as long as you can. Of course, it is in your best interest to participate heavily in the 'meta discussion' that takes place at Shapado.com and vote on the features and bug fixes that you want.

• matrix multiplication with MPI [on hold]

  - by user3695701

  I'm working on an assignment on matrix multiplication with MPI. A*B=C. the requirement is that B should be vertically partitioned. Here's what I intend to do: broadcast matrix A to all processes and scatter B into several slices with each slice containing n/p columns. The following code only works when the number of process(p) is 1. when p1(say 2), I got [cluster2:21080] *** Process received signal *** [cluster2:21080] Signal: Segmentation fault (11) [cluster2:21080] Signal code: Address not mapped (1) [cluster2:21080] Failing at address: (nil) [cluster2:21080] [ 0] /lib/libpthread.so.0(+0xf8f0) [0x7f49f38108f0] [cluster2:21080] [ 1] /lib/libc.so.6(memcpy+0xe1) [0x7f49f35024c1] [cluster2:21080] [ 2] /usr/lib/libmpi.so.0(ompi_convertor_unpack+0x121)[0x7f49f47c88e1] [cluster2:21080] [ 3] /usr/lib/openmpi/lib/openmpi/mca_pml_ob1.so(+0x8a26) [0x7f49f0dcea26] [cluster2:21080] [ 4] /usr/lib/openmpi/lib/openmpi/mca_btl_tcp.so(+0x662c) [0x7f49efce462c] [cluster2:21080] [ 5] /usr/lib/libopen-pal.so.0(+0x1ede8) [0x7f49f42e0de8] [cluster2:21080] [ 6] /usr/lib/libopen-pal.so.0(opal_progress+0x99) [0x7f49f42d5369] [cluster2:21080] [ 7] /usr/lib/openmpi/lib/openmpi/mca_pml_ob1.so(+0x5585) [0x7f49f0dcb585] [cluster2:21080] [ 8] /usr/lib/openmpi/lib/openmpi/mca_coll_tuned.so(+0xcc01) [0x7f49eeeb1c01] [cluster2:21080] [ 9] /usr/lib/openmpi/lib/openmpi/mca_coll_tuned.so(+0x266c) [0x7f49eeea766c] [cluster2:21080] [10] /usr/lib/openmpi/lib/openmpi/mca_coll_sync.so(+0x1388) [0x7f49ef0c0388] [cluster2:21080] [11] /usr/lib/libmpi.so.0(MPI_Bcast+0x10e) [0x7f49f47d025e] [cluster2:21080] [12] ./out(main+0x259) [0x401571] [cluster2:21080] [13] /lib/libc.so.6(__libc_start_main+0xfd) [0x7f49f3498c8d] [cluster2:21080] [14] ./out() [0x400f29] [cluster2:21080] *** End of error message *** Can someone help me?

• How come Java doesn't accept my LinkedList in a Generic, but accepts its own?

  - by master chief

  For a class assignment, we can't use any of the languages bultin types, so I'm stuck with my own list. Anyway, here's the situation: public class CrazyStructure <T extends Comparable<? super T>> { MyLinkedList<MyTree<T>> trees; //error: type parameter MyTree is not within its bound } However: public class CrazyStructure <T extends Comparable<? super T>> { LinkedList<MyTree<T>> trees; } Works. MyTree impleements the Comparable interface, but MyLinkedList doesn't. However, Java's LinkedList doesn't implement it either, according to this. So what's the problem and how do I fix it? MyLinkedList: public class MyLinkedList<T extends Comparable<? super T>> { private class Node<T> { private Node<T> next; private T data; protected Node(); protected Node(final T value); } Node<T> firstNode; public MyLinkedList(); public MyLinkedList(T value); //calls node1.value.compareTo(node2.value) private int compareElements(final Node<T> node1, final Node<T> node2); public void insert(T value); public void remove(T value); } MyTree: public class LeftistTree<T extends Comparable<? super T>> implements Comparable { private class Node<T> { private Node<T> left, right; private T data; private int dist; protected Node(); protected Node(final T value); } private Node<T> root; public LeftistTree(); public LeftistTree(final T value); public Node getRoot(); //calls node1.value.compareTo(node2.value) private int compareElements(final Node node1, final Node node2); private Node<T> merge(Node node1, Node node2); public void insert(final T value); public T extractMin(); public int compareTo(final Object param); }
