• SQL Server 2000 tables

  - by klork

  We currently have an SQL Server 2000 database with one table containing data for multiple users. The data is keyed by memberid which is an integer field. The table has a clustered index on memberid. The table is now about 200 million rows. Indexing and maintenance are becoming issues. We are debating splitting the table into one table per user model. This would imply that we would end up with a very large number of tables potentially upto the 2,147,483,647, considering just positive values. My questions: Does anyone have any experience with a SQL Server (2000/2005) installation with millions of tables? What are the implications of this architecture with regards to maintenance and access using Query Analyzer, Enterprise Manager etc. What are the implications to having such a large number of indexes in a database instance. All comments are appreciated. Thanks

• The best way to organize WPF projects

  - by Mike

  Hello everybody, I've started recently to develop a new software in WPF, and I still don't know which is the best way to organize the application, to be more productive with Visual Studio and Expression Blend. I noticed 2 annoying things I'd like to solve: I'm using Code Contracts in my projects, and when I run my project with Expression Blend, it launches the static analysis of the code. How can I stop that? Which configuration of the project does Blend use by default? I've tried to disable Code Contracts in a new configuration. It works in VS as the static analysis is not launched, but it has no effects in Blend. I've thinked about splitting the Windows Application in 2 parts: the first one containing the views of the WPF (app.exe) and the second one being the core of the project, with the logic code (app.core.dll), and I would just open the former project in Blend. Any thoughts about that? Thanks in advance Mike

• Python: Split by 1 or more occurrences of a delimiter

  - by Adam Matan

  Hi, I have a formatted string from a log file, which looks like: >>> a="test result" That is, the test and the result are split by some spaces - it was probably created using formatted string which gave test some constant spacing. Simple splitting won't do the trick: >>> a.split(" ") ['test', '', '', '', ... '', '', '', '', '', '', '', '', '', '', '', 'result'] split(DELIMITER, COUNT) cleared some unnecessary values: >>> a.split(" ",1) ['test', ' result'] This helped - but of course, I really need: ['test', 'result'] I can use split() followed by map + strip(), but I wondered if there is a more Pythonic way to do it. Thanks, Adam

• I need to Split a string based on a complex delimiter

  - by Jason

  In C# I need to split a string (a log4j log file) into array elements based on a particular sequence of characters, namely "nnnn-nn-nn nn:nn:nn INFO". I'm currently splitting this log file up by newlines, which is fine except when the log statements themselves contain newlines. I don't control the input (the log file) so escaping them somehow is not an option. It seems like I should be able to use a comparator or a regex to identify the strings, but String.Split does not have an option like that. Am I stuck rolling my own, or is there a pattern or framework component that can be of help here?

• Split ExtJS for incremental (on demand) download.

  - by Kabeer

  Hello. I had earlier asked whether I can remove un-utilized JavaScript code from ExtJS library. JSBuilder was the answer. What about being able to download widgets on-demand? I ask this because I have discovered this from the of markup generated by Coolite (ASP.Net framework that wraps ExtJS). So do I have to go through a meticulous process of splitting the library myself or is there a better way? BTW I'd like to avoid using Coolite.

• Best practices for large solutions in Visual Studio (2008)

  - by Eyvind

  We have a solution with around 100+ projects, most of them C#. Naturally, it takes a long time to both open and build, so I am looking for best practices for such beasts. Along the lines of questions I am hoping to get answers to, are: how do you best handle references between projects should "copy local" be on or off? should every project build to its own folder, or should they all build to the same output folder(they are all part of the same application) are solutions folders a good way of organizing stuff? I know that splitting the solution up into multiple smaller solutions is an option, but that comes with its own set of refactoring and building headaches, so perhaps we can save that for a separate thread :-)

• parsing numbers in a javascript array

  - by George

  Hi I have a string of numbers separated by commas, "100,200,300,400,500" that I'm splitting into an array using the javascript split function: var data = []; data = dataString.split(","); I'm trying to parse the values of the array using parseFloat and then store them back into the array. I'd then like to add up the numbers in the array and store it as another variable, "dataSum". I've got the following code, but I can't get it working: var dataSum = ""; for (var i=0; i < data.length; i++) { parseFloat(data[i]); dataSum += data[i]; } So at the end of all this, I should be able to access any of the parsed numbers individually data[0], data[1], etc... and have a total number for dataSum. What am I doing wrong?

• Java parsing UTF8

  - by Jack

  I have the following issue with a UTF8 files structured as following: FIELD1§FIELD2§FIELD3§FIELD4 Looking at hexadecimal values of the file it uses A7 to codify §. So according to this codify it should be UTF8, but it's strange because A7 7F so 1 byte shouldn't be enough to codify §. So I tried using directly a BufferedReader with a specified charset: BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(input), utf8)) but when I try to tokenize the string with SmartTokenizer st = new SmartTokenizer(toTokenize, "§") (the SmartTokenizer is a modified version of the StringTokenizer that keeps empty tokens) no splitting occurs, and if I try to print the string I obtain FIELD1?FIELD2?FIELD3?... so § used in the file is different from the one specified as a the delimiter, and it's not able to print out it too. So what's the problem here? Maybe the original file should use 2 bytes to store §?

• mysql: how to set max_allowed_packet for shared hosting?

  - by Sadi

  Hello, I need to set (increase) max_allowed_packet. But the problem is I am using a shared hosting. So, I can not access the .ini or .cnf file. Also I can not use the SET command. How can I am able to set a value (actually increase) for the max_allowed_packet, without asking the hosting support. I have no SSH access there. EDIT: I am trying to use VB 4.0.3. In there the attachment size is limited by it. So, I do not think splitting the file can be an option in this case. Thank you Sadi

• How to Filter more than one field using WPF AutoCompleteBox

  - by Drew

  i am trying to customize the suggestions on the AutoCompleteBox in the WPF Tool kit. Right now i have a last name field which when the user enters characters a query runs that retrieves the top 10 records based on that last name. i would also like to filter by first name, i tried splitting out the comma and searching by the last name and the characters entered in the first name. however, as soon as a space or comma is entered into the autocompletebox, the suggest functionality stops working, which I believe is because the ValueMemberPath property is set to be last name. Is there a work around for this, or a way to modify the ValueMemberPath to handle multiple values? Thanks!

• T-SQL: Opposite to string concatenation - how to split string into multiple records

  - by kristof

  I have seen a couple of questions related to string concatenation in SQL. I wonder how would you approach the opposite problem: splitting coma delimited string into rows of data: Lets say I have tables: userTypedTags(userID,commaSeparatedTags) 'one entry per user tags(tagID,name) And want to insert data into table userTag(userID,tagID) 'multiple entries per user Inspired by Which tags are not in the database? question EDIT Thanks for the answers, actually more then one deserves to be accepted but I can only pick one, and the solution presented by Cade Roux with recursions seems pretty clean to me. It works on SQL Server 2005 and above. For earlier version of SQL Server the solution provided by miies can be used. For working with text data type wcm answer will be helpful. Thanks again.

• AS3: How to access pixel data efficiently?

  - by JonoRR

  I'm working a game. The game requires entities to analyse an image and head towards pixels with specific properties (high red channel, etc.) I've looked into Pixel Bender, but this only seems useful for writing new colors to the image. At the moment, even at a low resolution (200x200) just one entity scanning the image slows to 1-2 Frames/second. I'm embedding the image and instance it as a Bitmap as a child of the stage. The 1-2 FPS situation is using BitmapData.getPixel() (on each pixel) with a distance calculation beforehand. I'm wondering if there's any way I can do this more efficiently... My first thought was some sort of spatial partioning coupled with splitting the image up into many smaller pieces. I also feel like Pixel Bender should be able to help somehow, however I've had little experience with it. Cheers for any help. Jonathan

• split a string based on pattern in java - capital letters and numbers

  - by rookie

  Hi all I have the following string "3/4Ton". I want to split it as -- word[1] = 3/4 and word[2] = Ton. Right now my piece of code looks like this:- Pattern p = Pattern.compile("[A-Z]{1}[a-z]+"); Matcher m = p.matcher(line); while(m.find()){ System.out.println("The word --> "+m.group()); } It carries out the needed task of splitting the string based on capital letters like:- String = MachineryInput word[1] = Machinery , word[2] = Input The only problem is it does not preserve, numbers or abbreviations or sequences of capital letters which are not meant to be separate words. Could some one help me out with my regular expression coding problem. Thanks in advance...

• loading data from file into 2d array

  - by Chris

  I am just starting with perl and would like some help with arrays please. I am reading lines from a data file and splitting the line into fields: open (INFILE, $infile); do { my $linedata = <INFILE>; my @data= split ',',$linedata; .... } until eof; I then want to store the individual field values (in @data) in and array so that the array looks like the input data file ie, the first "row" of the array contains the first line of data from INFILE etc. Each line of data from the infile contains 4 values, x,y,z and w and once the data are all in the array, I have to pass the array into another program which reads the x,y,z,w and displays the w value on a screen at the point determined by the x,y,z value. I can not pas the data to the other program on a row-by-row basis as the program expects the data to in a 2d matrtix format. Any help greatly appreciated. Chris

• android call log like design

  - by Alxandr

  I'm trying to create a design for a list that looks like (and mostly behaves like) the call log, like shown here: I don't need all the design, but what I'm trying to achieve is the two-columned design with the splitter in-between, and the behavior that if I click on the main item (the left part) one thing happens (in this case, you open some details about the call), and if you press the outer right part something else happens (you call the contact). I'm pretty new to android, but I've managed to do most of the designs I wanted so far, so I don't need the entire layout for this one, only the part that does the splitting and the splitter. And if possible it would be nice to know how to map the clicks appropriately, though I think I might be able to find that out by my self.

• Hyphenate a random string to an exact format

  - by chrissygormley

  Hello, I am creating a random ID using the below code: from random import * import string # The characters to make up the random password chars = string.ascii_letters + string.digits def random_password(): return "".join(choice(chars) for x in range(32)) This will output something like: 60ff612332b741508bc4432e34ec1d3e I would like the format to be in this format: 60ff6123-32b7-4150-8bc4-432e34ec1d3e I was looking at the .split() method but can't see how to do this with a random id, also the hyphen's must be at these places so splitting them by a certain amount of digits is out. I'm asking is there a way to split these random id's by 8 number's then 4 etc. Thanks

• TFSBuild/MSBuild and Project Reference vs File Reference

  - by anon

  We Have a large VS solution using project references which is build by TFS Build like so: Solution - Project 1 - Project 2 - Project ... - Project N Because the solution is too large we have several smaller solutions which we use day to day: SubSolution - Project 1 - Project 19 The problem is that developers working on SubSolution find that it is not building because the project references could not be found, so they change the projects to use file references. This then goes on to break the TFS Build which cannot find these file references because they have not been built yet (Even though the projects are in the same solution). Is there a way around this tug of war between the two types of references. What is the correct way of splitting out your solutions?

• Deploying a Rails App to Multiple Servers using Capistrano - Best Practices

  - by Louise

  I have a rails application that I need to deploy to 3 servers - machine1.com, machine2.com and machine3.com. I want to be able to deploy it to all machines at once and each machine individually. Can someone help me out with a skeleton Capistrano config file / recipe? Should it all be in deploy.rb or should I break it out in machine1.rb, etc? I thought I was on the right track getting Capistrano to take in command line arguments, but it choked when I tried set the roles within the namespaces. I'd pass in 'hosts=1,2,3' as an argument and set the role:app/web/db to "machine#{host}.com" after splitting on the command and going into an each do |host| {}... Anyway, other than creating 4 different deploy.rb files and renaming it before running cap:deploy each time, I'm stumped. I'd like to be able to do the following: cap deploy:machine1:latest_version_from_svn cap deploy:all_machines:latest:version_from_svn Just don't know if it should all be in deploy.rb split up with namespaces or if it should be broken into multiple deploy*.rb files.

• How do I split an NSString by each character in the string?

  I have the following code, which works as I expect. What I would like to know if there is an accepted Cocoa way of splitting a string into an array with each character of the string as an object in an array? - (NSString *)doStuffWithString:(NSString *)string { NSMutableArray *stringBuffer = [NSMutableArray arrayWithCapacity:[string length]]; for (int i = 0; i < [string length]; i++) { [stringBuffer addObject:[NSString stringWithFormat:@"%C", [string characterAtIndex:i]]]; } // doing stuff with the array return [stringBuffer componentsJoinedByString:@""]; }

• MX Records - go to two servers?

  - by Jim Beam

  Right now I have a single mail server for IMAP. Let's say I want to introduce Exchange but not all users will be on it. Some users will be on my "legacy" IMAP, others on the "new" Exchange. Is it possible to "split up" your users (from the same e-mail domain) on two services like this? What would the MX records look like? My guess is that this isn't possible, but thought I'd ask. By the way, I realize that Exchange can offer IMAP and all that, but my question is more about splitting users across services and the MX records. The actual protocols above are only examples.

• SQL Split function.

  - by Wardy

  Hi guys, I'm looking for a way to do this ... SELECT FirstName, LastName, Split(AddressBlock, ' ', 1), Split(AddressBlock, ' ', 2), PostCode FROM Contacts The arguments I want to pass are ... The address The separator (current situation requires 2 spaces but this might be a comma or a space followed by a comma) or something else (it varies). The address part I want to return (i don't always need all parts of the split result). I seem to be able to find a few examples of splitting functions about the internet but they return a table containing the entire set of split parts. My SQL skills aren't that great so I need the answer to be ultra simple. I'm always working with nvarchar data and the function needs to be reusable.

• Best way to Fingerprint and Verify html structure.

  - by Lukas Šalkauskas

  Hello there, I just want to know what is your opinion about how to fingerprint/verify html/links structure. The problem I want to solve is: fingerprint for example 10 different sites, html pages. And after some time I want to have possibility to verify them, so is, if site has been changed, links changed, verification fails, othervise verification success. My base Idea is to analyze link structure by splitting it in some way, doing some kind of tree, and from that tree generate some kind of code. But I'm still in brainstorm stage, where I need to discuss this with someone, and know other ideas. So any ideas, algos, and suggestions would be usefull.

• strtok wont accept: char *str

  - by bks

  strtok wont work correctly when using char *str as the first parameter (not the delimiters string). does it have something to do with the area that allocates strings in that notation? (which as far as i know, is a read-only area). thanks in advance example: //char* str ="- This, a sample string."; // <---doesn't work char str[] ="- This, a sample string."; // <---works char delims[] = " "; char * pch; printf ("Splitting string \"%s\" into tokens:\n",str); pch = strtok (str,delims); while (pch != NULL) { printf ("%s\n",pch); pch = strtok (NULL, delims); } return 0;

• Restore Emacs Session/Desktop

  - by Patrick McLaren

  I've been searching for how to restore an emacs session, with no luck. I'm looking to restore all previously open buffers, some of which might contain erc, shells, directory listings, files, etc. Every time I open emacs, I spend a considerable amount of time arranging my buffers; splitting them into rows and columns, opening a shell, arranging irc channels. It takes a while to get onto work. I've tried adding the following to my init.el (desktop-save-mode 1) And then using M-x desktop-save. This only seems to restore files that are open, not shells or anything else running within buffers. I've also checked the following questions (sorry, not able to post links yet): Session management in emacs using Desktop library Emacs session / projects / window management Emacs: reopen buffers from last session on startup? And read through: DeskTop and EmacsSession at emacswiki.org/emacs/SessionManagement Here's a screenshot example of my emacs session. A simple answer would be to just focus on real work :P
