    Re: Replace. to _ in a string

    Use stringVariable.Replace(".", "_") since you don't seem to know what a regular expression is. stringVariable.Replace(".", "_") will return a new string with "." replaced with "_" in stringVariable,...

    Re: smooth resize image

    As an answer to your question, I can only quote myself:


    You cannot affect the way the browser renders an image (although it's possible that loading an image through a filter in Internet Explorer...

    Re: smooth resize image

    If by "messed up" you mean it looks pixelated (even when reducing the size), that depends entirely on how the browser decides to render the image. Certain browsers such as Safari resize the image...
  4. Re: WHERE clause with multiple values from one field [Access]

    For your first problem you could use this:

    SELECT EmployeeID
    FROM r_rights
    WHERE AreaID = 1 OR AreaID = 3
    GROUP BY EmployeeID
    HAVING COUNT(EmployeeID) = 2;

    It'll get the ID's of all...

    A char will always take up the specified length, while a varchar will only take up the length of its value. I.e.:

    A char(10) value set to 'Hello' will become
    'Hello ' (five spaces in the...
  6. Re: Query the amount of records that repeated in a table

    I'm spoiled with SQL Server 2005 and would do this:

    SELECT
    CASE WHEN COUNT(SN) > 1 THEN 1 ELSE 0 END AS Repeating
    FROM YourTable
    GROUP BY SN
    ) SELECT SUM(Repeating) FROM Temp;...

    Re: Problem with ON clause in MySQL 5

    That is strange... If offer and currency are the only tables with a column named currency_id, you could try changing

    ON t4.currency_id = t1.currency_id
    to

    USING (currency_id)
    and see if that...

    Re: use combo box change color.

    The multiple ID shouldn't be ignored if you're using it anywhere (such as in CSS or JavaScript) because it can cause unexpected behavior on your page.

    Anyways, to get the currently selected option...
  9. Re: About to GO insane! ajax + php == :*( Please gurus help me!

    XMLHttpRequest creates an entirely new request, separate from your page. This means it doesn't matter what form(s) you have on your page (which wouldn't make sense anyways - how would it know what...

    Re: AI for Game Programming

    That's not really a code-related question, in my opinion. It depends mostly on how your game is presented graphically.

    Re: AI for Game Programming

    For an MMORPG, A.I. is quite simple when compared to other game genres (especially FPS and RTS.) I'd still go for an FSM, yes, but since an MMORPG server has to handle a great deal of actors at once,...

    Generally FSM are predictable and not very suitable for adaptiveness. The reason I suggested it is because they are simple enough to understand and implement. If you're going for more complex,...

    Re: AI for Game Programming

    I'd go for a finite state machine (FSM) because they're easy to work with. Basically you give your actor an initial state and let it switch between states depending on what it senses. Say you've got...
