  • Remove querystring from URL

    - by Malcolm Frexner
    What is an easy way to remove the querystring from a Path in Javascript? I have seen a plugin for Jquery that uses window.location.search. I can not do that: The URL in my case is a variable that is set from AJAX. var testURL = '/Products/List?SortDirection=dsc&Sort=price&Page=3&Page2=3&SortOrder=dsc'

  • QueryPerformanceCounter Not Working Properly on Amazon EC2 with Win Server 2008

    - by timeitquery
    Our application makes use of QueryPerformanceCounter to measure timings. When running it on Amazon EC2 instances we are noticing number that are out of whack. The symptoms look very similar to what has been reported with virtualized machines on HP proreliant servers, however all the articles state that this was not the case for Windows Server 2008. The articles recommended modifing the boot.ini to /USEPMTIMER - however, this seem to be missing from the documentation on bcdedit - which replaced boot.ini

  • Prevent SQL Injection in Dynamic column names

    - by Mr Shoubs
    I can't get away without writing some dynamic sql conditions in a part of my system (using Postgres). My question is how best to avoid SQL Injection with the method I am currently using. EDIT (Reasoning): There are many of columns in a number of tables (a number which grows (only) and is maintained elsewhere). I need a method of allowing the user to decide which (predefined) column they want to query (and if necessary apply string functions to). The query itself is far too complex for the user to write themselves, nor do they have access to the db. There are 1000's of users with varying requirements and I need to remain as flexible as possible - I shouldn't have to revisit the code unless the main query needs to change - Also, there is no way of knowing what conditions the user will need to use. I have objects (received via web service) that generates a condition (the generation method is below - it isn't perfect yet) for some large sql queries. The _FieldName is user editable (parameter name was, but it didn't need to be) and I am worried it could be an attack vector. I put double quotes (see quoted identifier) around the field name in an attempt to sanitize the string, this way it can never be a key word. I could also look up the field name against a list of fields, but it would be difficult to maintain on a timely basis. Unfortunately the user must enter the condition criteria, I am sure there must be more I can add to the sanatize method? and does quoting the column name make it safe? (my limited testing seems to think so). an example built condition would be "AND upper(brandloaded.make) like 'O%' and upper(brandloaded.make) not like 'OTHERBRAND'" ... Any help or suggestions are appreciated. Public Function GetCondition() As String Dim sb As New Text.StringBuilder 'put quote around the table name in an attempt to prevent some sql injection 'http://www.postgresql.org/docs/8.2/static/sql-syntax-lexical.html sb.AppendFormat(" {0} ""{1}"" ", _LogicOperator.ToString, _FieldName) Select Case _ConditionOperator Case ConditionOperatorOptions.Equals sb.Append(" = ") ... End Select sb.AppendFormat(" {0} ", Me.UniqueParameterName) 'for parameter Return Me.Sanitize(sb) End Function Private Function Sanitize(ByVal sb As Text.StringBuilder) As String 'compare against a similar blacklist mentioned here: http://forums.asp.net/t/1254125.aspx sb.Replace(";", "") sb.Replace("'", "") sb.Replace("\", "") sb.Replace(Chr(8), "") Return sb.ToString End Function Public ReadOnly Property UniqueParameterName() As String Get Return String.Concat(":" _UniqueIdentifier) End Get End Property

  • PDB: exception when in console - full stack trace

    - by EoghanM
    When at the pdb console, entering a statement which causes an exception results in just a single line stack trace, e.g. (Pdb) someFunc() *** TypeError: __init__() takes exactly 2 arguments (1 given) However I'd like to figure out where exactly in someFunc the error originates. i.e. in this case, which class __init__ is attached to. Is there a way to get a full stack trace in Pdb?

  • Does a wrapper class for a COM interop IStream already exist?

    - by AnthonyWJones
    I'm about to write a Wrapper for a COM interop IStream so that code that expects a standard .NET Stream can use it. However it occurs to me that this sort of thing may already have been done before (although I haven't been able to find it myself with web searching). So I'm just putting this out here in case I'm about to re-invent the wheel. Note I've come across code implementing IStream wrapping a .NET stream but I need the reverse.

    - by jpartogi
    Dear all, IF I am to develop a native application on blackberry, what would be the recommended way to call remote JSON object? As I understand native blackberry apps is coded using Java, would it still be able to contact a remote JSON object from Ruby on Rails? Has there been any blackberry framework to ease this use case? Thank you very much for your help. I really appreciate it.

  • stop and split generated sequence at repeats - clojure

    - by fitzsnaggle
    I am trying to make a sequence that will only generate values until it finds the following conditions and return the listed results: case head = 0 - return {:origin [all generated except 0] :pattern 0} 1 - return {:origin nil :pattern [all-generated-values] } repeated-value - {:origin [values-before-repeat] :pattern [values-after-repeat] { ; n = int ; x = int ; hist - all generated values ; Keeps the head below x (defn trim-head [head x] (loop [head head] (if (> head x) (recur (- head x)) head))) ; Generates the next head (defn next-head [head x n] (trim-head (* head n) x)) (defn row [x n] (iterate #(next-head % x n) n)) ; Generates a whole row - ; Rows are a max of x - 1. (take (- x 1) (row 11 3)) Examples of cases to stop before reaching end of row: [9 8 4 5 6 7 4] - '4' is repeated so STOP. Return preceding as origin and rest as pattern. {:origin [9 8] :pattern [4 5 6 7]} [4 5 6 1] - found a '1' so STOP, so return everything as pattern {:origin nil :pattern [4 5 6 1]} [3 0] - found a '0' so STOP {:origin [3] :pattern [0]} :else if the sequences reaches a length of x - 1: {:origin [all values generated] :pattern nil} The Problem I have used partition-by with some success to split the groups at the point where a repeated value is found, but would like to do this lazily. Is there some way I can use take-while, or condp, or the :while clause of the for loop to make a condition that partitions when it finds repeats? Some Attempts (take 2 (partition-by #(= 1 %) (row 11 4))) (for [p (partition-by #(stop-match? %) head) (iterate #(next-head % x n) n) :while (or (not= (last p) (or 1 0 n) (nil? (rest p))] {:origin (first p) :pattern (concat (second p) (last p))})) # Updates What I really want to be able to do is find out if a value has repeated and partition the seq without using the index. Is that possible? Something like this - { (defn row [x n] (loop [hist [n] head (gen-next-head (first hist) x n) steps 1] (if (>= (- x 1) steps) (case head 0 {:origin [hist] :pattern [0]} 1 {:origin nil :pattern (conj hist head)} ; Speculative from here on out (let [p (partition-by #(apply distinct? %) (conj hist head))] (if-not (nil? (next p)) ; One partition if no repeats. {:origin (first p) :pattern (concat (second p) (nth 3 p))} (recur (conj hist head) (gen-next-head head x n) (inc steps))))) {:origin hist :pattern nil}))) }

  • Stateful EJBs in web application?

    - by Sebastien Lorber
    Hello I never used stateful EJBs. I understand that a stateful EJB can be useful with a java client. But i wonder: in which case to use them on a web application? And how? Should we put these stateful beans in Session (because of stateless http)? Is it a good practice? (without debating too much about stateful vs stateless)

  • How do you get Lighttpd to compress CodeIgniter's "clean urls"?

    - by ocdcoder
    I was looking at PageSpeed on my test website and noticed that Lighttpd wasn't compressing my HTML (but was compressing my javascript and css files). I'm assuming this is because I'm using CodeIgniter and it's clean url system and since the requests don't have file extensions, Lighttpd doesn't have the rule to compress it. That being the case, how do I get Lighttpd to compress my HTML? Is this something I shouldn't be doing? Or something I need to specially configure Lighttpd for?

  • When creating an bitmap image from scratch in VB.Net, the quality stinks?

    - by ajl
    The Vb.Net application creates a bitmap from scratch and either converts to a tiff or sends it to a printer. In both cases, the quality of the image (in this case the font) is not good at all. The sample code listed below creates the graphics object that I use to write to the image. Dim gr2 As Graphics = Graphics.FromImage(New Bitmap(800, 1000), Imaging.PixelFormat.Format32bppPArgb))

  • Segmenting a double array of labels

    - by Ami
    The Problem: I have a large double array populated with various labels. Each element (cell) in the double array contains a set of labels and some elements in the double array may be empty. I need an algorithm to cluster elements in the double array into discrete segments. A segment is defined as a set of pixels that are adjacent within the double array and one label that all those pixels in the segment have in common. (Diagonal adjacency doesn't count and I'm not clustering empty cells). |-------|-------|------| | Jane | Joe | | | Jack | Jane | | |-------|-------|------| | Jane | Jane | | | | Joe | | |-------|-------|------| | | Jack | Jane | | | Joe | | |-------|-------|------| In the above arrangement of labels distributed over nine elements, the largest cluster is the “Jane” cluster occupying the four upper left cells. What I've Considered: I've considered iterating through every label of every cell in the double array and testing to see if the cell-label combination under inspection can be associated with a preexisting segment. If the element under inspection cannot be associated with a preexisting segment it becomes the first member of a new segment. If the label/cell combination can be associated with a preexisting segment it associates. Of course, to make this method reasonable I'd have to implement an elaborate hashing system. I'd have to keep track of all the cell-label combinations that stand adjacent to preexisting segments and are in the path of the incrementing indices that are iterating through the double array. This hash method would avoid having to iterate through every pixel in every preexisting segment to find an adjacency. Why I Don't Like it: As is, the above algorithm doesn't take into consideration the case where an element in the double array can be associated with two unique segments, one in the horizontal direction and one in the vertical direction. To handle these cases properly, I would need to implement a test for this specific case and then implement a method that will both associate the element under inspection with a segment and then concatenate the two adjacent identical segments. On the whole, this method and the intricate hashing system that it would require feels very inelegant. Additionally, I really only care about finding the large segments in the double array and I'm much more concerned with the speed of this algorithm than with the accuracy of the segmentation, so I'm looking for a better way. I assume there is some stochastic method for doing this that I haven't thought of. Any suggestions?
