    Hello all, I have heard the name Jon Skeet in several forums, some times in "inappropriate places". Kindly shed some light on this. Is there is really some "Jon Skeet" or its just a myth among fraternity.

  • Websphere 7 simple realm (like tomcat-users.xml)

    - by Heavy Bytes
    I am trying to port a J2EE app from Tomcat to Websphere and I'm not too familiar with Websphere. The only problem I am having is authorization (I use basic-authentication in my web.xml). In Tomcat I use the tomcat-users.xml file to define my users/passwords and to what roles they belong. How do I do this "simply" in Websphere? When deploying the EAR to Websphere it also asks me to map my role from web.xml to a user or group. Do I have to set up some sort of realm? Custom user registry? Thanks. UPDATE: I configured a Standalone custom registry, however I can't get a log-in prompt for username/password. It works just fine in Tomcat, and it doesn't in Websphere. Code from web.xml <security-constraint> <web-resource-collection> <web-resource-name>basic-auth security</web-resource-name> <url-pattern>/*</url-pattern> </web-resource-collection> <auth-constraint> <role-name>HELLO_USER</role-name> </auth-constraint> <user-data-constraint>NONE</user-data-constraint> </security-constraint> <login-config> <auth-method>BASIC</auth-method> </login-config> <security-role> <role-name>HELLO_USER</role-name> </security-role>

  • SyncFramework upgrade from 1.0 to 2.0 Sql Server CE database change tracking issue

    - by Andronicus
    I'm trying to upgrade an application that uses Sync Framework 1.0 to synchronise a SqlServerCe database with SqlServer 2005. On the client, the existing database already has change tracking enabled, but when the sync is initiated SyncFramework 2.0 fails to find the last Sync Received anchor and then tries to re=initialize the Change tracking, which fails. I get the exception... {System.Exception} = {"The specified change tracking operation is not supported. To carry out this operation on the table, disable the change tracking on the table, and enable the change tracking."} It seems like all I can do is delete the local database and recreate it. Which is not a great solution for us, since some of the data in the clients database is not synced with the server, and our users would prefer not to loose this data in the upgrade. Is there any reason why SyncFramework 2.0 cannot locate the existing Last received sync anchor?

  • Access Control Lists basics

    - by vtortola
    Hi, I'm gonna add authorization, user and groups management to my application, basically... you will can define a set of permissions for a concrete user or group. For example, you could specify whom can use a concrete resource. So I want to ensure that my assumptions about ACLs are right: A basic rule could be "Grant", "Deny", "NoSet". User permissions have priority over group permissions. "Deny" statement has priority over "Grant". For example, user "u1" belongs to group "A", the resource "X" has this ACL "u1:grant,A:deny" user "u1" should be able to access the resource, shouldn't it? If a resource has no ACL set... does it means that anyone can access it? should I provide a default ACL? Any document about ACL in a general way? Cheers.

  • Microsoft Sync Framework with Mutliple Client and Server Database

    - by David Osborn
    I'm working on changes to an application to have a local data store instead of connecting directly to the database server. The client app will then sync changes both ways between the server database and its local data store. I'm trying to implement the syncing solution using Microsoft Sync Framework. To be clear there is no server application, only the database server, but there are multiple clients. I have started implementing two classes that implement FullEnumerationSimpleSyncProvider, one called LocalSyncProvider and one called ServerSyncProvider. The LocalSyncProvider knows how to enumerate, insert, update, delete items from the local data store, and the ServerSyncProvider knows how to enumerate, insert, update, delete items from the database server. They each use the provided SqlMetadataStore and store the two metadata stores (one for the local and one for the server) on the local drive of the client. This means that each client will have its own metadata store for its local data store and its own metadata store for the server database. Is this actually going to work, does there need to exists only one server metadata store, or do I need to be using the Sync Framework differently?

  • Using C# and Repository Factory and the error: The requested database is not defined in configurati

    - by odiseh
    hi I am using Repository factory for visual studio 2008 for a personal project. It generated a class called ProductRepository which inherits from Repository. The ProductRepository has a constructor which gets a database name as string and passes it to its base (I mean Repository ). So when I try to debug my project step by step, I pass my database name to ProductRepository but it raises the following error: The requested database is not defined in configuration. What's wrong?

  • Cannot assign - must be a "UserProfile" instance

    - by webvulture
    I have a class UserProfile defined which takes the default user as a foreign key. Now another class A has a foreign key to UserProfile. So for saving any instance in class A, how do i give it the userprofile object. Also, does making a class UserProfile mean that class user is still used and class UserProfile is just some other table? I need to know this as I have to take care of the user profile creation, so I should know what gets stored where? -- Confused

  • Sessions and cookies

    - by Derek
    I currently have a website that allows my visitors to login via a simple script i've pasted together and wrote. Currently I only use sessions to keep visitors logged in. Are there any advantages to adding cookies to my website to store user logged in status? Or is there a better way altogether?

  • Wix create non advertised shortcut for all users / per machine

    - by mcdon
    In WIX, how do you create a non advertised shortcut in the allusers profile? So far I've only been able to accomplish this with advertised shortcuts. I prefer advertised shortcuts because you can go to the shortcut's properties and use "find target". In the tutorials I've seen use a registry value for the keypath of a shortcut. The problem is they use HKCU as the root. When HKCU is used, and another user uninstalls the program (since it's installed for all users) the registry key is left behind. When I use HKMU as the root I get an ICE57 error, but the key is removed when another user uninstalls the program. I seem to be pushed towards using HKCU though HKMU seems to behave correctly (per-user vs all-users). When I try to create the non advertised shortcut I get various ICE error such as ICE38, ICE43, or ICE 57. Most articles I've seen recommend "just ignore the ice errors". There must be a way to create the non advertised shortcuts, without creating ICE errors. Please post sample code for a working example.

  • Web framework for an application utilizing existing database?

    - by tputkonen
    A legacy web application written using PHP and utilizing MySql database needs to be rewritten completely. However, the existing database structure must not be changed at all. I'm looking for suggestions on which framework would be most suitable for this task? Language candidates are Python, PHP, Ruby and Java. According to many sources it might be challenging to utilize rails effectively with existing database. Also I have not found a way to automatically generate models out of the database. With Django it's very easy to generate models automatically. However I'd appreciate first hand experience on its suitability to work with legacy DBs. Also I appreciate suggestions of other frameworks worth considering.

  • Connect Access 2007 to SQL Server 2008 Database

    - by Peter
    Hi, I've seen numerous answers to similar questions like this one. I haven't seen on the web many people have asked the seemingly simple question "How do I connect Access 2007 to an SQL server 2008 database" - but all of the answers describe how you can migrate from access 2007 to an sql server 2008 database, or they describe how to connect access 2007 to an sql server 2005 database. I can't find any simple solution to my problem (and probably this is a problem for many others). Here is the question (sorry for the over emphasis): How do I connect to an sql server 2008 database (and I mean 2008, not 2005 :) ) from access 2007? Apologies again for the over emphasis, but this very simple question, and what I thought should be a very simple task seems, yes, ... impossible! I tried running sql server browser, enabling pipes, TCP etc, but it seems that with 2008 SQLEXPRESS just isn't recognised! Please can someone help with this. Peter

  • What makes good software good?

    - by Jonta
    People probably have a lot of different answers here, like good...: scalability, speed, usability, stability, consistency, completeness, absence of bugs, accessibility, documentation, code-quality and so on. There are a lot of philosophies on development of software. Like the UNIX-philosophy. Often vague and not easy to understand. I am looking for statements such as the one cited below. Which you can ask about the software when it's in the design-stage, is ready to be coded, and has been coded and is ready for launch. The software I am talking about, is of course the software made for the end-user. Ken Rockwell wrote: "I expect that it will let me get more accomplished in less time." (Here one could ask "will this let me get more accomplished in less time?")

  • Using a datanase class in my user class?

    - by Josh
    In my project I have a database class that I use to handle all the MySQL stuff. It connects to a database, runs queries, catches errors and closes the connection. Now I need to create a members area on my site, and I was going to build a users class that would handle registration, logging in, password/username changes/resets and logging out. In this users class I need to use MySQL for obvious reasons... which is what my database class was made for. But I'm confused as to how I would use my database class in my users class. Would I want to create a new database object for my user class and then have it close whenever a method in that class is finished? Or do I somehow make a 'global' database class that can be used throughout my entire script (if this is the case I need help with that, no idea what to do there.) Thanks for any feedback you can give me.

  • Lightweight Object->Database in python

    - by pehrs
    I am in need of a lightweight way to store dictionaries of data into a database. What I need is something that: Creates a database table from a simple type description (int, float, datetime etc) Takes a dictionary object and inserts it into the database (including handling datetime objects!) If possible: Can handle basic references, so the dictionary can reference other tables I would prefer something that doesn't do a lot of magic. I just need an easy way to setup and get data into an SQL database. What would you suggest? There seems to be a lot of ORM software around, but I find it hard to evaluate them.

  • what is the best way to stream a audio file to website users/listners

    - by Naveen Chamikara Gamage
    I'm developing a music site which will stream audio files stored in a server to users, audio files will be played through flash player placed in a webpage.. As I heard I need to use a streaming media server for streaming audio files ( like 2mb to 3mb in size).. Do I need to use one? I found some streaming media server softwares like http://www.icecast.org - but as in their documentation, It is used for streaming radio stations and live streaming purposes, but I just need to stream audio files faster and in low size (low bandwidth) with good quality.. I heard I need to encode the audio files first and then send them to listeners and in their end audio files need to be decoded again. Is that true? How can I do that? if I need to use a special web server, where should I host my files? Any good hosting providers? if I host audio files in a normal web server, they will use HTTP or TCP to deliver my audio files to users/ listners but I found that HTTP and TCP are not good ways to use for multi media purposes like streaming audio and video files, and they are used for delivering HTML and stuff. I found I should use RSTP or UDP for streaming audio files.. What should I use? I know that .MP3 files has much better quality than the other formats but it also gives huge size to the audio files.. which format should I use for audio files? Most of the best quality audio files are more than 7mb so I'm planning to convert them my self using a software so I could get low size files with some level of good quality. If I'm converting my audio files what is the good BITRATE I should use for my files? Any known best softwares for converting audio files while keeping quality in a good level? Note** - I know that I will not need complex requirements at the beginning of the site but I wanted to what are the best ways like they are using for soundcloud.com

  • Using a .MDF SQL Server Database with ASP.NET Versus Using SQL Server

    - by Maxim Z.
    I'm currently writing a website in ASP.NET MVC, and my database (which doesn't have any data in it yet, it only has the correct tables) uses SQL Server 2008, which I have installed on my development machine. I connect to the database out of my application by using the Server Explorer, followed by LINQ to SQL mapping. Once I finish developing the site, I will move it over to my hosting service, which is a virtual hosting plan. I'm concerned about whether using the SQL Server setup that is currently working on my development machine will be hard to do on the production server, as I'll have to import all the database tables through the hosting control panel. I've noticed that it is possible to create a SQL Server database from inside Visual Studio. It is then stored in the App_Data directory. My questions are the following: Does it make sense to move my SQL Server DB out of SQL Server and into the App_Data directory as an .mdf file? If so, how can I move it? I believe this is called the Detach command, is it not? Are there any performance/security issues that can occur with a .mdf file like this? Would my intended setup work OK with a typical virtual hosting plan? I'm hoping that the .mdf database won't count against the limited number of SQL Server databases that can be created with my plan. I hope this question isn't too broad. Thanks in advance! Note: I'm just starting out with ASP.NET MVC and all this, so I might be completely misunderstanding how this is supposed to work.

  • C# integer primary key generation using Entity Framework with local database file (Sdf)

    - by Ronny
    Hello, I'm writing a standalone application and I thought using Entity Framework to store my data. At the moment the application is small so I can use a local database file to get started. The thing is that the local database file doesn't have the ability to auto generate integer primary keys as SQL Server does. Any suggestions how to manage primary keys for entities in a local database file that will be compatible with SQL Server in the future? Thanks, Ronny

  • Access Database using do.cmd openform where clasue - returning all values

    - by primus285
    DoCmd.OpenForm "Database Search", acFormDS, , srcLastName & "AND " & srcFirstName This is only a small sample of the where clause - there are many more terms. First, there is a set of If, Then type tings up top that set the variable srcLastName and srcFirstName to some value. These are not the problem and work just fine. The trouble is getting them to return all values (for instance if you only want to search by one, on neither(return full database list)) Thus far I have settled for (in the if then section): srcLastName = "[Lastname] =" & Chr(34) & cboLastName & Chr(34) - to search for something and srcLastName = "[Lastname] <" & Chr(34) & "Nuthin" & Chr(34) - to return everything (not equal to an absurd and mispelled database term.) The trouble is that data that is null is also not returned. If I have a null firstname, it will not show up in any search period. is there a term I can set [lastname] and [firstname] equal to that will return EVERYTHING (null, open, data, numbers, wierd stuff and otherwise) in a search an SQL form of "give me everything shes got scotty" if you will. the real issue here comes from the data entry - if I could just know that the people would enter everything 100% of the time, this code would work. but forget to enter the persons age or whatever, and it wont return that entry. So far, the only other solution I have come up with is to put a counter in each if then statement. The count will go up by one for each thing that is being searched by. Then if the count is = 1, then I can search by something like just DoCmd.OpenForm "Database Search", acFormDS, , srcLastName or DoCmd.OpenForm "Database Search", acFormDS, , srcFirstName then revert back to the DoCmd.OpenForm "Database Search", acFormDS, , srcLastName & "AND " & srcFirstName when the count is 2 or more truoble here is that it only works for one (unless I so wanted to create a custon list of 2 combined, 3 combined, 4 combined, but that is not happening)
