  • QuickGraph - is there algorithm for find all parents (up to root vertex's) of a set of vertex's

    - by Greg
    Hi, In QuickGraph - is there algorithm for find all parents (up to root vertex's) of a set of vertex's. In other words all vertex's which have somewhere under them (on the way to the leaf nodes) one or more of the vertexs input. So if the vertexs were Nodes, and the edges were a depends on relationship, find all nodes that would be impacted by a given set of nodes. If not how hard is it to write one's own algorithms?

  • Why is fulltextsearch for phrase ignored in SQL Server?

    - by cpt.oneeye
    I am executing the following SQL statement on an indexed SQL Server 2008 R2 database. SELECT * FROM mydatabase WHERE (CONTAINS(ColumnA,'"The Apple is red"')) The problem is that it returns too many entries. It also returns entries where 'ColumnA' contains only one of the words ('Apple' or 'is' or 'red'...) and not only the entries which contains the exact phrase. According to MSDN this should be the way to search for a phrase. Thanks cpt.oneeye

    - by Narek
    I want to use a field (kind of QTextEdit), which is capabale of storing picture and text (like MS Word is doing) and it serializes and deserialaizes picture+text data. Is there any Qt Widget that allows us to manipulate with picture and text simultaniously and it has set/get functions which operate with serializable type? In othger words, I want to know if there exsists any Qt widget that can store picture+text and has "get" types of function that returns the content of that widgets editable area, which is a Type that could be serialized with QDataStream.

  • Is it possible to virtualize war file execution without separate J2EE container deployments?

    - by Smith
    Let's say I want to allow my developers to upload their war files to a web app (not the application server itself) running on our intranet and that web app would then run those wars as if they were separate apps deployed individually in our J2EE container. In other words, we are not actually deploying the wars as separate apps in the container - they are simply running side-by-side inside this one web app that acts like a J2EE container. Is that possible? Something like a war virtualization app?

  • Create web application with ajax from the begining or add ajax later?

    - by klew
    I'm working on my first Ruby on Rails aplication and it's quite big (at least for me ;) - database has about 25 tables). I'm still learning Ruby and Rails and I never wrote anything in Javascript nor Ajax. Should I add Ajax to my application from the begining? Or maybe it will be better to add it latter? Or in the other words: is it (relatively) easy to add ajax to existing web application?

  • What needs to be passed to an editor from a keyboard app to move the cursor one char left?

    - by yno
    What key code does an Android editor app expect the keyboard app to send when it is going to be interpreted as a left arrow? In other words, what is the keyboard program supposed to send to its calling program (some kind of editor) if the user intends to move the cursor one char to the left? A related issue: what do the minus values for the "android:codes" attribute mean? () Any pointers to these issues will be appreciated.

  • When running UPDATE ... datetime = NOW(); will all rows updated have the same date/time?

    - by Darryl Hein
    When you run something similar to: UPDATE table SET datetime = NOW(); on a table with 1 000 000 000 records and the query takes 10 seconds to run, will all the rows have the exact same time (minutes and seconds) or will they have different times? In other words, will the time be when the query started or when each row is updated? I'm running MySQL, but I'm thinking this applies to all dbs.
