• JBoss envers and huge audit tables

  - by LeChe

  All, I am auditing my JEE application with JBoss Evers and the nature of my application causes the audit table to grow very fast. The historic data is queried infrequently and access time is not really an issue, apart from the data from the last week. This data IS queried frequently and access needs to be fast. Ideally, I would split the data and distribute it over two tables, with the older data in compressed format. Unfortunately, Envers does not allow spreading data over multiple tables as far as I can tell from the docs. Does somebody have any idea what would be the best way to achieve this (if possible while still using Envers)? Cheers, LeChe

• PostgreSQL like + Hibernate problem

  - by Marat_Galiev

  Hi all. I want to do search in PostgreSQL for INTEGER based columns. if (!sSearch.isEmpty()) { sSearch = sSearch.replaceAll("[^a-zA-Z0-9]", "_").toLowerCase(); String[] search = sSearch.split(" "); sWhere = " "; for (NewsColumns column : NewsColumns.values()) { for (String s : search) { sWhere += "lower(" + column + "::TEXT) LIKE '%" + s + "%' OR "; } } sWhere = sWhere.substring(0,sWhere.length()-3); } Ok, I want to convert INT value to String before search, with '::TEXT' expression. But after executing I'm getting: org.hibernate.QueryException: Not all named parameters have been set: [:TEXT] [select * from news WHERE lower(ID::TEXT) LIKE '%5%' Exception. Looks like hibernate parse my convert exp as parameter. Any help is appreciated. Thanks.

• Lines-of-code counting for many C# solutions

  - by Eric

  I am currently researching a solution for counting lines of code in C#. I pretty much need a combination of the following two tools: http://richnewman.wordpress.com/2007/07/01/c-and-vbnet-line-count-utility/ http://www.locmetrics.com/index.html My problem is that I need to recursively scan a folder containing a lot of visual studio solutions. So can't really use the first tool without any major work on its code, as it's only able to scan a single solution at a time. But I also need to split the results for each solution, preferably even the contained projects. This disqualifies the second tool I found. I also found NDepend which suffers from the same problem. Do you know of any free tools that do what I need? I am unable to find anything suitable.

• How to read comma separated values from text file in JAVA?

  - by user1425223

  I have got this text file with latitude and longitude values of different points on a map. I want to store these coordinates into a mySQL database using hibernate. I want to know how can I split my string into latitudes and longitudes? What is the general way to do these type of things that is with other delimiters like space, tab etc.?

• Which SOA architecture is most appropriate for a Java application?

  - by Robert Greiner

  I am currently working on a pretty large Java 6 application where we are looking to split some of our functionality out into a service oriented architecture. It seems that the primary SOA framework for the application space is OSGi and I have been looking into Felix and Knopplerfish but I wanted to make sure that this isn't my only option. Does it make sense to use an actual web service protocol for our application like SOAP, even though we are not building a web app? Is this even acceptable? Have any of you used an implementation of OSGi (Felix, etc.) with your desktop application? if so, how did it go? Do you know of anything better? We're all pretty new to SOA here so any help would be greatly appreciated.

• PowerShell: Read text, regex sort, write output to file and formatting

  - by Bill Hunter

  I am a Powershell novice and have run into a challenge in reading, sorting, and outputting a csv file. The input csv has no headers, the data is as follows: 05/25/2010,18:48:33,Stop,a1usak,10.128.212.212 05/25/2010,18:48:36,Start,q2uhal,10.136.198.231 05/25/2010,18:48:09,Stop,s0upxb,10.136.198.231 I use the following piping construct to read the file, sort and output to a file: (Get-Content d:\vpnData\u62gvpn2.csv) | %{,[regex]::Split($, ",")} | sort @{Expression={$[3]}},@{Expression={$_[1]}} | out-file d:\vpnData\u62gvpn3.csv The new file is written with the following format: 05/25/2010 07:41:57 Stop a0uaar 10.128.196.160 05/25/2010 12:24:24 Start a0uaar 10.136.199.51 05/25/2010 20:00:56 Stop a0uaar 10.136.199.51 What I would like to see in the output file is a similar format to the original input file with comma dilimiters: 05/25/2010,07:41:57,Stop,a0uaar,10.128.196.160 05/25/2010,12:24:24,Start,a0uaar,10.136.199.51 05/25/2010,20:00:56,Stop,a0uaar,10.136.199.51 But I can't quite seem to get there. I'm almost of the mind that I'll have to write another segment to read the newly produced file and reset its contents to the preferred format for further processing. Thoughts?

• Complicated conditional SQL query

  - by DevAno1

  I'm not even sure if it's possible but I need it for my Access database. So I have following db structure : Now I need to perform a query that takes category_id from my product and do the magic : - let's say product belongs to console (category_id is in table Console) - from console_types take type_id, where category_id == category_id - but if product belongs to console_game (category_id is in table console_game) - from console_game take game_cat_id, where category_id == category_id I'm not sure if mysql is capable of such thing. If not I'm really f&%ranked up. Maybe there is a way to split this into 2,3 separate queries ?

• What is the maximum number of controls that a VBA form can hold?

  - by Lunatik

  I'm currently building an Excel 2003 app that requires a horribly complex form and am worried about limitations on the number of controls. It currently has 154 controls (counted using Me.Controls.Count - this should be accurate, right?) but is probably only about a third complete. The workflow really fits a single form, but I guess I can split it up if I really have to. I see evidence in a Google search that VB6 (this usually includes VBA) has a hard limit of 254 controls in a form. However, I created a dummy form with well over 1200 controls which still loaded and appeared to work just fine. I did get some 'out of memory' errors when trying to add specific combinations of controls though, say 800 buttons and 150 labels, leading me to think that any limit might be affected by the memory requirements of each type of control. Does anyone have any information that might help ensure that I or, more importantly, other users with differing environments don't run into any memory issues with such a large form?

• Identifying individual values in a text box using Flash

  - by Jamash1989

  I want to identify specific strings in a text box from user input to add to a score variable, like so - if (userWords.text == firstWord) { score = score + 1; } The example given adds 1 to the score, but if a user adds a space then a second word the text box views it as a whole and not individual words, resulting in no values added to the score variable. The problem lies with the whole text box being viewed as one entire string. Instead, I want to split it up so word1 will add 1 to the score, word2 will add 1 to the score, etc. I am ultra confused with this problem, so thank you to anyone that may help.

• Loop colours from variables for graphics.py [Python 3.2]

  - by user1056548

  I am creating a graphics program that draws 100 x 100 squares next to each other depending on the user-specified grid size. The user also inputs 4 colours for the squares to be coloured (e.g. if they enter red,green,blue,yellow the squares will be coloured in that order, repeating the colours). Is it possible to loop the colours from the variables the user has given? Here is what I have so far: def main(): print ("Please enter four comma seperated colours e.g.: 'red,green,blue,yellow'\n\ Allowed colours are: red, green, blue, yellow and cyan") col1, col2, col3, col4 = input("Enter your four colours: ").split(',') win = GraphWin ("Squares", 500, 500) colours = [col1, col2, col3, col4] drawSquare (win, col1, col2, col3, col4, colours) win.getMouse() win.close() def drawSquare(win, col1, col2, col3, col4, colours): for i in range (4): for j in range (len(colours)): colour = colours[j] x = 50 + (i * 50) circle = Circle (Point (x,50), 20) circle.setFill(colour) circle.draw(win) I think I should be using a list in some way, but can't work out exactly how to do it. Can anybody help?

• Regex to get rid of everything past the first sentence in a string in php

  - by andufo

  I need to get rid of everything after the first dot (if there is more than 1 sentence), but at the same time, cases like e.g. have to be omited. Some line e.g., when people do something. Extra content. Some line (some parenthesis). Extra content. I need to get rid of the "Extra content.". The returning value should be: Some line e.g., when people do something. Some line (some parenthesis). So far I've come with this regex taken from other threads, but it only finds the dots and split the string into an array. preg_replace('/(?<!\.)\.(?!(\s|$|\,|\w\.))/','',$text); Any ideas? Thanks.

• Getting value from key pair value into appended property using jQuery

  - by Neil

  How do I get the value from a key pair value into the rel property of an anchor tag? When I split the code to put the value in the correct place it doesn't work, the end of the a tag would appear on screen instead value wouldn't be applied. When I look at the resulting code in console in Firebug the rel and href swapped order so the rel is first. The 'key' should be and is in the correct location but the 'value' needs to be applied to the rel attribute. What am I doing wrong? $(function() { var obj = {"firstThing":"4","secondThing":"6","aThirdThing":"2","anotherThing":"3","followedByAnother":"4"}; $.each(obj, function(key,value) { $('#newmine').append("<li class='tagBlocks'>","<a href='#' rel=''>",value," ",key); }); });

• Blackberry Widget Packager saves my files in strange places

  - by chibineku

  I have just installed the Blackberry Widget Packager and Blackberry Web Plug-In for Eclipse, and everything works fine, but my files are output to strange places. For example, I tried putting my zipped source files in the folder Blackberry Widget Packager/web and I got an error during packaging. Packaging works when the .zip is in the same directory as wwbp, though. When a widget is successfully created, the executable .jar file and the .rapc files are put in some stupid folder like users/user/temp/widgetname094098456, and the other files are split between two folders in Blackberry Widget Packager/bin. This is slightly annoying as I don't want to be spending time herding my files. Anyone have any thoughts on why my files are being scattered like this?

• C# Importing Large Volume of Data from CSV to Database

The data needs to be formatted(e.g. name column needs to be split into first name and last name, etc.) I need to do this in a efficiently as possible i.e. time constraints I am siding with the option of reading, transforming and loading the data using a C# application row-by-row? Is this ideal, if not, what are my options? Should I use multithreading?

• How can I extract just the elements I want from a Perl array?

  Hey I'm wondering how I can get this code to work. Basically I want to keep the lines of $filename as long as they contain the $user in the path: open STDERR, ">/dev/null"; $filename=`find -H /home | grep $file`; @filenames = split(/\n/, $filename); for $i (@filenames) { if ($i =~ m/$user/) { #keep results } else { delete $i; # does not work. } } $filename = join ("\n", @filenames); close STDERR; I know you can delete like delete $array[index] but I don't have an index with this kind of loop that I know of.

• Does C# have an equivalent to JavaScript's encodeURIComponent()?

  - by travis

  In JavaScript: encodeURIComponent("©v") == "%C2%A9%E2%88%9A" Is there an equivalent for C# applications? For escaping HTML characters I used: txtOut.Text = Regex.Replace(txtIn.Text, @"[\u0080-\uFFFF]", m => @"&#" + ((int)m.Value[0]).ToString() + ";"); But I'm not sure how to convert the match to the correct hexadecimal format that JS uses. For example this code: txtOut.Text = Regex.Replace(txtIn.Text, @"[\u0080-\uFFFF]", m => @"%" + String.Format("{0:x}", ((int)m.Value[0]))); Returns "%a9%221a" for "©v" instead of "%C2%A9%E2%88%9A". It looks like I need to split the string up into bytes or something. Edit: This is for a windows app, the only items available in System.Web are: AspNetHostingPermission, AspNetHostingPermissionAttribute, and AspNetHostingPermissionLevel.

• How do you store sets in Cassandra?

  - by Ben W

  I'd like to convert this JSON to a data model in Cassandra, where each of the arrays is a set with no duplicates: var data = { "data1": { "100": [1, 2, 3], "200": [3, 4] }, "data2": { "k1", [1], "k2", [4, 5] } } I'd like to query like this: data["data1"]["100"] to retrieve the sets. Anyone know how you might model this in Cassandra? (The only thing I came up with was columns whose name was a set value and the value of the column was an empty string, but that felt wrong.) It's not OK to serialize the sets as JSON or some other string, which would make this much easier. Also, I should note that it's OK to split data1 and data2 into separate ColumnFamilies, it's not necessary that they're keys in the same one.

• Use matching value of a RegExp to name the output file.

  - by fx42

  I have this file "file.txt" which I want to split into many smaller ones. Each line of the file has an id field which looks like "id:1" for a line belonging to id 1. For each id in the file, I like to create a file named idid.txt and put all lines that belong to this id in that file. My brute force bash script solution reads as follows. count=1 while [ $count -lt 19945 ] do cat file.txt | grep "id:$count " >> ./sets/id$count.txt count='expr $count + 1' done Now this is very inefficient as I have do read through the file about 20.000 times. Is there a way to do the same operation with only one pass through the file? - What I'm probably asking for is a way to use the value that matches for a regular expression to name the associated output file.

  I followed this article on making a table-per-type inheritance model for my entities, but I get the following error when I try to add an instance of a subclass to the database. Here is how I create the subtype: var cust = db.Users.CreateObject<Customer>(); // Customer inherits User db.Users.AddObject(cust); db.SaveChanges(); I get the following error when I make that last call: "A value shared across entities or associations is generated in more than one location. Check that mapping does not split an EntityKey to multiple store-generated columns." With the following inner exception: "An item with the same key has already been added." Any ideas on what I could be missing?
