  • What are good/fast methods to pull data from a database using JavaScript?

    - by Yatrix
    I'm pretty new to web technologies and I am creating a filter control that will have cascading controls. We are doing a lot of this through JavaScript and are debating the best route to take to the database. HTTPHandlers, WebServices and Ajax are all being considered (or a combination of them). We want to be able to handle a million rows in theory, so it has to be scalable to at that. We are going through JavaScript as our page must not do post-backs, if your'e wondering. I'm asking from an architectural standpoint, but will take any useful information. Links, control suggestions - anything you have, I'll happily listen to.

  • How can I retrieve a MS SQL Express Database from a non-booting computer?

    - by Redandwhite
    A client has a very important database that has not been backed up in 6 months. The PC has promptly failed. The Windows directory is corrupt, and the computer will not boot. It had a Microsoft SQL Server Express 2005 database on it. I have access to the hard drive by booting in with an Ubuntu Live CD, but I am not sure if I can find the database. I am not sure what I am looking for, or where to look either. The dead machine had Windows XP on it.

  • Why do I have redundant routing in Windows 7?

    - by Mark
    I'm trying to better understand my routing tables. My routing table is: IPv4 Route Table =========================================================================== Active Routes: Network Destination Netmask Gateway Interface Metric 1. 0.0.0.0 0.0.0.0 192.168.1.1 192.168.1.151 25 2. 127.0.0.0 255.0.0.0 On-link 127.0.0.1 306 3. 127.0.0.1 255.255.255.255 On-link 127.0.0.1 306 4. 127.255.255.255 255.255.255.255 On-link 127.0.0.1 306 5. 192.168.1.0 255.255.255.0 On-link 192.168.1.151 281 6. 192.168.1.151 255.255.255.255 On-link 192.168.1.151 281 7. 192.168.1.255 255.255.255.255 On-link 192.168.1.151 281 8. 224.0.0.0 240.0.0.0 On-link 127.0.0.1 306 9. 224.0.0.0 240.0.0.0 On-link 192.168.1.151 281 10. 255.255.255.255 255.255.255.255 On-link 127.0.0.1 306 11. 255.255.255.255 255.255.255.255 On-link 192.168.1.151 281 =========================================================================== Most of those entries make sense to me, but a few confuse me: 2 and 3 seem redundant, as do 2 and 4. Why not just 2? 5 and 6 seem redundant, as do 5 and 7. Why not just 5? I'm trying to grok routing tables and this bit is still confusing me.

  • How do I force an exchange database to become "active"?

    - by makerofthings7
    We had a catastrophic failure where all that remains is a single edb file. No backups. No log files. The database that remains is on the "passive" copy. The "active" copy is missing, but the server is active. The Exchange console reports that the edb file needs to be reseeded, however there is no source to reseed from. How do I make the "invalid" database file (missing logs) valid? How do I make exchange recognize this as a valid database to use as a primary?

  • Will taking a job that's web and database related limit my software development opportunities later on?

    - by someone
    I love programming, particularly OOP. My school experience was mostly in Java/OOP, and I had a job for a limited time in Java, Python, and other OOP kind of languages. However, a move necessitated a change in jobs, and what I've ended up with now is a web-development and database intensive job. I may possibly hold this job for several years. My question is, will this limit my choices later on? Will I be able to find another Java / software-development kind of job, or will I be rejected because my experience will be mostly in a different area?

  • How can I make my Java desktop application to run on different computers in a network locally and updating same mysql database?

    - by JaMpa
    I have developed Java desktop application for registration of students in the computer laboratories in our college, but what I need is to make this application whenever it runs on any computer (Windows XP machines) on the laboratory each and every data filled by the college students goes to the same MySql database (through WAMP server) running on the server machine (Win Server 2003). Also, I need this application to run during booting of windows computers in the laboratory for the purpose when any student tries to switch on any PC in the comp lab before interfacing the desktop icons should sign in through user name and password when he has already registered or signing up in order for getting the access.

  • Building a simple web app with database? [on hold]

    - by Zooce
    I'm building a simple airline reservation system (web app) for a class. I'm trying to find out where to start learning about implementing and integrating a sql database. User's should be able to search for available flights based on destination and departure cities and the like. A good example would be Google Flights. I'd like to access a data base with all of the flight information and display it within tables on the web page. Admins should be able to modify the databases as well. I've tried to learn about things like Node.js, PHP, and AJAX, but most of the tutorials that I've found have been difficult to understand. Any suggestions would be really appreciated, thanks!

  • How can you replace a link's target in Greasemonkey?

    - by Derek
    I'm trying to write a script in Greasemonkey that will replace a link's target with something else, but with my limited Javascript knowledge I don't really know how to do this. Basically I'm trying to find all links containing a certain string of characters (ex: //a[contains(@href, 'xx')] ), and either replace them with another link, or append something to them (replacing 'abc123.com' with 'zyx987.com' or 'abc123.com' with 'abc123.com/folder'). If you could point me on the right path I'd greatly appreciate it.
