  • C++ - 3 possible values in Variable?

    - by noryb009
    I need to store a 30 letter combination, but each letter can only be "0", "1" or "2". When I use sizeof(myString), it returns 32. I want to use this 30 letter combination to access a row of an array, so I'm wondering if it is possible to use a 3 value bool of some sort to store 1 of 3 values in.

  • javascript, jQuery: how to save values instead of the references

    - by Patrick
    hi, I'm using the following lines to store the location of an object. var lightboxTop = $('#lightbox').css('top'); var lightboxLeft = $('#lightbox').css(' left'); I'm successively moving this object in my element, and I want to restore it previous position with the stored variables. But, I'm afraid javascript is saving the values by reference so I lose the initial positions. Am I correct ? How can I solve this ? thanks

  • Look up values in a BDB for several files in parallel

    - by biznez
    What is the most efficient way to look up values in a BDB for several files in parallel? If I had a Perl script which did this for one file at a time, would forking/running the process in background with the ampersand in Linux work? How might Hadoop be used to solve this problem? Would threading be another solution?

  • Scaling range of values with negative numbers

    - by Pradeep Kumar
    How can I scale a set of values to fit a new range if they include negative numbers? For example, I have a set of numbers (-10, -9, 1, 4, 10) which have to scaled to a range [0 1], such that -10 maps to 0, and 10 maps to 1. The regular method for an arbitrary number 'x' would be: (x - from_min) * (to_max - to_min) / (from_max - from_min) + to_min but this does not work for negative numbers. Any help is appreciated. Thanks!!

  • How can I retrieve two values from jquery-autocomplete

    - by RedMist
    I need my application to auto-complete on a company name, but also fill in a hidden form field with the ID of that company selected. I believe it's possible to return pair values, with the pipe separator, such as........ Microsoft|10 Oracle|20 Sybase|30 And indeed this seems to work, but I don't know how to access the 2nd argument.

  • check all values match using prototype

    - by snaken
    Using prototype, is there a simple method of checking that a group of values match, for example - can this code be refined to a single line or something otherwise more elegant? var val = ''; var fail = false; $('form').select('.class').each(function(e){ if(!val){ val = $F(e); }else{ if(val != $F(e)) fail = true; } });

  • Filter to values in collection in one query

    - by dotnetdev
    Hi, I have the following LINQ query: List<string> Types = (List<string>) Directory.GetFiles(@"C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727") Where(x => System.IO.Path.GetFileNameWithoutExtension(x).Contains("Microsoft")) .ToList<string>(); How could I modify this so it can only get the values stored in a collection, without writing another LINQ query (which I assume will impact performance?)? Thanks

  • Returning Null values with COUNT

    - by Randy B.
    With this query, I get a result that is two short of the table because they are not included in count, and I would like get the NULL values in the result. To do this, I am pretty sure I need to use a subquery of some kind, but I am not sure how, since the attribute in question is an aggregate. SELECT Equipment.SerialNo , Name, COUNT(Assignment.SerialNo) FROM Equipment INNER JOIN Assignment ON Assignment.SerialNo = Equipment.SerialNo GROUP BY Equipment.SerialNo, Name

    Dunno why it is...heres the coding for it. http://pastebin.org/301343 I know theres a lot of repetitiveness in the coding...but its because the arrays were retuning null so I got tired of messing with them. Everything works until it reaches line 224, which returns null values.
