    - by Brian Frost

It uses a TDatabase component with several paradox (.db) tables. Is it simple to rejig the TDatabase settings to use a database on a shared machine so that several of us can access it together across the network? If so, what would be the steps needed please?

  • How do Relational Databases Work Under the Hood?

    - by Pierreten
    I've always been interested in how you can throw some SQL at at database, and it nearly instantaneously returns your results in an orderly manner without thinking about it as anything other than a black box. What is really going on? I'm pretty sure it has something to do with how values are laid out regularly in memory, similar to an array; but aside from that, I don't know much else. How is SQL parsed in a manner to facilitate all of this?

  • Is there an OData Server Library for Java or PHP to EXPOSE OData?

    - by Rob
    Hi, I am wondering if there is or why there isn't a ADO.NET Data Services Server Library for Java? I need to expose a database from a Java Server but i only see Microsot providing clients for java not server parts. How is that an open standard when you need .NET/Windows to expose it? Thanks for any pointers to that. Same interesting for PHP as well.

  • Active Directory validate service account and user accounts

    - by Padur
    Hello folks I have an issue here, I guess you all know what is AD service account and why it is used for, if not please see the below description ? SSL-Explorer requires a dedicated Active Directory account to use for authenticating AD users. This account serves as a link to your Active Directory database. If the Service Account is not found on your AD database then the SSL-Explorer service will not start. Well I have Active Directory service account details and user submitted login/password details.In the code below I validated service account by giving MEMBER_GRPUP and adminPassword and I check whether the user exists in Active Directory by submitting samaaccountname but my question here is how do I validate the password submitted for that user? I am not sure how to do this, I appreciate if anybody has any suggestions on this. Thanks for your time. public boolean validateUserFromActiveDirectory(String userId) { final String MEMBER_GROUP = "CN=asdadasd,OU=asdasdasd Accounts,OU=adasdas,OU=asdasdas,DC=asdasdas,DC=asdasdas,DC=adasdasd,DC=asdasdasd"; String employeeNumber = ""; final String LDAP_INIT_CTX = "com.sun.jndi.ldap.LdapCtxFactory"; final String LDAP_URL = "ldap://xx-ssssssss.eee.eee.eeeee.eeeee:636"; final String MY_ATTRS[] = { "employeeNumber" }; String adminPassword = "somepassword"; String securityProtocol = "ssl"; boolean isValidUser = false; try { Hashtable env = new Hashtable(); env.put(Context.INITIAL_CONTEXT_FACTORY, LDAP_INIT_CTX); env.put(Context.PROVIDER_URL, LDAP_URL); env.put(Context.SECURITY_AUTHENTICATION, "simple"); env.put(Context.REFERRAL, "follow"); env.put(Context.SECURITY_PRINCIPAL, MEMBER_GROUP); env.put(Context.SECURITY_CREDENTIALS, adminPassword); env.put(Context.SECURITY_PROTOCOL, securityProtocol); //C:\Documents and Settings\yourusername\Local Settings\Temp File tf = File.createTempFile("adentTruststore", ".jks"); tf.deleteOnExit(); byte buffer[] = new byte[0x1000]; ClassLoader cl = JNDI.class.getClassLoader(); InputStream in = cl.getResourceAsStream( "someTruststore.jks"); FileOutputStream out = new FileOutputStream(tf); int cnt; while ((cnt = in.read(buffer)) != -1) out.write(buffer, 0, cnt); in.close(); out.close(); System.setProperty("javax.net.ssl.trustStore", tf .getAbsolutePath()); DirContext context = new InitialLdapContext(env, null); SearchControls searchControls = new SearchControls(); searchControls.setSearchScope(SearchControls.SUBTREE_SCOPE); NamingEnumeration results = context.search( "XX=ent,XX=abc,XX=aaaaa,XX=aaaa", "(sAMAccountName=" + userId + ")", searchControls); if (results != null && results.hasMore()) { //some logic } } } catch (Exception e) { e.printStackTrace(); } return isValidUser; }

  • What does really happen when we do a BEGIN TRAN in SQL Server 2005?

    - by Misnomer
    Hi all, I came across this issue or maybe something I didn't realize but I did a Begin Tran and had some code inside it and never ran a commit or rollback as I forgot about it. That caused all many of the database queries or even just a simple select top 1000 command were just sitting on loading..? Now it probably has put some locks on the tables I guess since it did not let me query them..but I just wanted to know what exactly happened and what are the practices to be followed here ?

  • Cannot delete from sys.tables

    - by Shimmy
    How can I perform this query on whatever way: delete from sys.tables where is_ms_shipped = 0 What happened is, I executed a very large query and I forgot to put USE directive on top of it, now I got a zillion tables on my master db, and don't want to delete them one by one. UPDATE: It's a brand new database, so I don't have to care about any previous data, the final result I want to achieve is to reset the master db to factory shipping.

  • Web-Frameworks for Education Management Systems?

    - by Indebi
    So, I'm working on an idea and I'll go into a brief overview of that but my question is, What are some good web frameworks for this situation? I have some experience in the following languages: C# Python I have considerably more experience in C# than Python, however I am expecting to learn new things. My idea is this, a completely web-based community-oriented Education Management System that focuses on making students and teachers day-to-day lives easier. For students it will provide a centralized place for them to do homework, study for tests, and reinforce concepts learned previously in class. For teachers it will give them a centralized place to handle assignments, attendance, homework, tests, and all other major parts of classroom management. All of that, but in a community-oriented fashion. Everything a teacher does is shared and open to constructive criticism, allowing other teachers to use their assignments/tests and for students or other teachers to comment, rate and criticize their assignments. This encourages an environment of openness that will allow teacher's to focus on teaching and student's to focus on learning. And that community wouldn't be limited to one school or school-district, this system would be completely school-independent. Please note that I have no problem with hearing constructive criticism on this idea, however I would prefer if this post was more focused on my question. I have somewhat explored about the following options: Django ASP.NET Ruby on Rails Silverlight (1) I have Django installed and I played with it for a little bit, I really like how easy setting up databases are and how it handles the database completely for you. I don't really know how to use it very well and I don't quite understand the Model-View-Controller paradigm(?) for it yet but I haven't thought about it much. I also like the fact that it uses Python. (2) I don't really like Visual Studio for developing in ASP.NET, I hate the way the web-designer works and it just feels clunky and old. I like the server-side development part though. I don't like how expensive ASP.NET and overall Visual Studio is, even if I do get it for free for now using DreamSpark (3) I haven't been able to explore much with this, I could not get Rails (or maybe Ruby) properly installed. I first installed it within RadRails and that didn't work so I uninstalled RadRails and then installed the latest version of Ruby off the official Windows Installer and then installed Ruby on Rails through gem and even after all that it still didn't work, so I installed Netbeans and attempted to use it there but it still did not work (4) I like Silverlight in some extents, I've played with this one the most, it's very similar to WPF (which I've used the most) in a lot of ways but I don't like how database connectivity works, at least in comparison to Django. I also dislike how expensive everything with Microsoft is, even if I get it for free for now with DreamSpark. I would like to hear some suggestions from experienced web-developers as to what I should use and why, or at least what some good options are for my scenario Your help would be very appreciated
