  • Detemining a database's OS with a SQL query?

    - by KaizenSoze
    I'm writing a tool to gather customer configuration information. One of the questions I want to answer, what OS is the customer database running on. I haven't found a generic way to find the OS with SQL and I can't create stored procedures on the customer's database. If there is a way, it's probably vendor specific. Suggestions? Thanks in advance.

  • How do I get the Virtual Machines folder on Win7?

    - by xpmore
    I'm writing a tool called XP-More, which should help manage Windows 7 Virtual Machines. The first thing the tool has to do when launched is find the VM folder. However, turns out that folder is not listed as a Windows Special Folder. I use a workaround, but it's unreliable. Ideally, Environment.GetFolderPath(Environment.SpecialFolder.VMFolder) or so would have done the job, but VMFolder is a fiction of my imagination. Is there any real way to get that folder?

  • drawbacks of storing all ''things' in a central table

    - by naiquevin
    Hi, I am not sure if there is a term to describe this, but I have observed that content management systems store all kinds of data in a single table with their bare minimum properties while the meta data is stored in another table in form of key value pairs. for eg. everything (blog posts, pages, images, events etc) is stored in one table and considered as a post. I understand that this allows for abstraction and easy extensibility we are considering designing our new project this way. It is not exactly a CMS but we plan to keep adding modules to it in stages. Lets say initially there will be only posts and images on which comments can be posted. Later on we might add videos which will also have the commenting feature. what are the drawbacks of this approach ? and will it work for a requirement like ours ? Thanks

  • "reduce" or "apply" using logical functions in Clojure

    - by Alex B
    I cannot use logical functions on a range of booleans in Clojure (1.2). Neither of the following works due to logical functions being macros: (reduce and [... sequence of bools ...]) (apply or [... sequence of bools ...]) The error saying that I "can't take value of a macro: #'clojure.core/and". How to apply these logical functions (macros) without writing boilerplate code?

  • Neat way of calling InvokeRequired and Invoke

    - by ho
    I seem to remember seeing some neat way of calling InvokeRequired and Invoke to avoid repeating too much code in every event handler but I can't remember what that was. So does anyone know a neat way of writing that code? Preferably for VB.Net 2005.

  • Second min cost spanning tree.

    - by Evil
    Hello. I'm writing an algorithm for finding the second min cost spanning tree. my idea was as follows: 1) Use kruskals to find lowest MST. 2) Delete the lowest cost edge of the MST. 3) Run kruskals again on the entire graph. 4) return the new MST. My question is this: Will this work? Is there a better way perhaps to do this?

  • Javascript: How to detect if a word is highlighted

    - by fterh
    I'm writing a Firefox addon that is triggered whenever a word is highlighted. However I need a script that detects when a word is highlighted, and I'm stuck. An example would be nytimes.com (when you're reading an article and you highlight a word, the reference icon pops up). However the nytimes.com script is super complex. I'm 16 and not much of a programmer, so that is definitely way out of my league.

For example, a mail client, telephone directory, a simple graphical editor, audio player. Thanks!

  • PHP difference between notice and warning

    - by Stegeman
    When writing code errors, warnings and notices can occur. I know the idea behind errors. I suppose a warning is there to inform you about something that can cause an error, but isn't a notice exaclty the same? I suppose a notice is not a message of something doing right ;). It's just a bit confusing to me. Can anybody tell the difference between those two and the way these messages should be treated.

    - by amitchd
    Hi, The connection string in my app.config for my C# project looks like Data Source=.\SQLEXPRESS;AttachDbFilename='|DataDirectory|\EIC.mdf';Integrated Security=True;User Instance=True" I am writing unit tests for the project and have the set the test run configuration to copy the EIC.mdf, but I do am not able to reference the Deployed copy of EIC.mdf to be referenced by the app.config I created for the test project. If I set it to Data Source=.\SQLEXPRESS;AttachDbFilename='EIC.mdf';Integrated Security=True;User Instance=True" It still does not find the mdf file.

  • File mode for creating+reading+appending+binary

    - by MihaiD
    I need to open a file for reading and writing. If the file is not found, it should be created. It should also be treated as a binary for Windows. Can you tell me the file mode sequence I need to use for this? I tried 'r+ab' but that doesn't create the files if they are not found. Thanks

  • 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?

  • event handling in C++

    - by Max
    Hi. I'm writing a game in C++, and I'm trying to get it to recognize keyboard and mouse events. Google tells me that boost.signal is suitable for event handling, but none of the code samples or tutorials I've found tell me how to associate a keypress or mouseclick with a function. Can anyone shed any light on this?

  • How do I keep my app from tracking bot requests as views

    - by trustfundbaby
    This is a general question about writing web apps. I have an application that counts page views of articles as well as a url shortner script that I've installed for a client of mine. The problem is that, whenever bots hit the site, they tend to inflate the page views. Does anyone have an idea on how to go about eliminating bot views from the view count of these applications?
