Add version control to existing SQL Server database

- by ederbf

I am part of a development team currently working with a database that does not have any kind of source control. We work with SQL Server 2008 R2 and have always managed the DB directly with SSMS. It now has ~340 tables and ~1600 stored procedures, plus a few triggers and views, so it is not a small DB. My goal is to have the DB under version control, so I have been reading articles, like Scott Allen's series (http://bitly.com/9cJmGR) and many old SO related questions. But I am still unable to decide on how to proceed. What I'm thinking of is to script the database schema in one file, then procedures, triggers and views in one file each. Then keep everything versioned under Mercurial. But of course, every member of the team can access SSMS and directly change the schema and procedures, with the possibility that any of us can forget to replicate those changes in the versioned files. What better options are there? And, did I forget any element worth having source control of?

Which data structure for List of objects + datagrid wiev

- by Martin

Hi, I have to develop a code which will store a list of objects, as example below 101, value 11, value 12, value 13 ...etc 102, value 21, value 22, value 23 ...etc 103, value 31, value 32, value 33 ...etc 104, value 41, value 42, value 43 ...etc Now, the difficulty is, that first column is an identifier, and whole table should always be sorted by it. Easy access to each element is required. Additionally, list should be easily updated, and extended by adding element at the end as well as in front and still keep being sorted by first column. Finally, I would like to be able to display values of the above in datagridview. What is most important is a performance of the implementation, as rows will be updated many times per second, and datagridview should be able to display all changes immediately. I was thinking about creating class for the values, and then a Dictionary but encountered a problem with displaying values in gridview. What would be the most optimal way of implementing the code? Thanks in advance Martin

Browser loading strategy, <head>...<body>

- by Bin Chen

I am inspecting some interesting behaviors of browser, I don't know it's in standard or not. If I put everythin inside <head></head>, the browser will only begin to render the page after all the resouces in head is retrieved. So I am thinking that put as little as possible things into head is one of the important website optimization techniques, is it right? My question is: If I put script/css in body or other parts of the html, how can I know that script has been loaded successfully so that I will not be calling a undefined function?

Working effectively unit tests / Anyone tried the in-assembly approach?

- by CodingCrapper

I'm trying to re-introduce unit testing into my team as our current coverage is very poor. Our system is quite large 40+ projects/assemblies. We current use a project named [SystemName].Test.csproj were all the test code is dumped and organised to represent the namespaces using folders. This approach is not very scalable and makes it difficult to find tests. I've been thinking about added a Tests folder to each project, this would put the unit tests "in the developers face" and make them easy to find. The downside is the Production release code would contain references to nunit, nmocks as well as the test code and test data.... Has anyone tried this approach? How is everyone else working with unit tests on large projects? Having a Tests project per "real" project/assembly would introduce too many new projs. Thanks in advance

Good error flagging | PHP

- by Wayne

For everyone that was thinking of the error_reporting() function, then it isn't, what I need is whenever a MySQL query has been done, and the statement has like if($result) { echo "Yes, it was fine... bla bla"; } else { echo "Obviously, the echo'ing will show in a white page with the text ONLY..."; } Whenever statements have been true or false, I want the error to be appeared when redirected with the header() function and echo the error reporting in a div somewhere on the page. Basically something like this: $error = ''; This part appears inside the div tags <div><?php echo $error; ?></div> So the error part will be echoed when redirected with the header() if($result) { $error = "Yes, it was fine... bla bla"; header("Location: url"); } else { $error = "Something wrong happened..."; header("Location: url"); } But that just doesn't work :(

check external website registration

- by Arsenal

Hi, I'm trying to create a PHP based game where you have to do all sorts of simple but un-obvious tasks in order to progress to the next level (eg. refresh browser, press keyboard combination, ...) Kinda like the game "this is the only level" (if anyone has ever heard of it) Now I was thinking: Would it be possible to create a level where they'd have to sign up at a different page in order to progress to the next level? So say for example they need to sign up to goal.com and if they're signed up they proceed to the next level. The page would need to constantly check if the signup process on the other site is completed. Is this even possbible? And if so, any thoughts on how? Thanks!

Storing a file in the user's directory in cross-platform Java

- by dalyons

I have a Java application that runs on Mac and Windows, directly off a CD/DVD with no installation. Now, I need to store a file containing per-user data (think favourites etc.) somewhere on the local file system, so that it can be written to. So, where do you think is a good location for this file? I am thinking something like: <USER_DOCUMENTS_AND_SETTINGS>/application data/myapp/favourites.db for windows <USER_HOME_DIR>/.myapp/favourites.db for mac/nix Thoughts? And does anyone know the best way to determine these paths within Java?

IIS url rewrite rewriting all .asp to .html

- by user335711

I need to create rules for web.config that will rewrite all requests for files with extension .html to .asp and redirect all .asp requests to .html Example: file_xyz.asp rewrites to file_xyz.html directory1/file_xyz.asp rewrites to directory1/file_xyz.html and file_xyz.html redirects to file_xyz.asp directory1/file_xyz.html redirects to directory1/file_xyz.asp What is the syntax for the rule Is this too broad a rule? If I should need for what ever reason to have a physical file such as file_abc.html how do I exclude it from the redirect rule? I am thinking I should just use ISAPI_Rewrite http://www.isapirewrite.com/ there seems to be a ton of resources out there for rewriting with htaccess and very little online help for using IIS 7 URL rewrite. Any thoughts and/or advice Thanks in advance

Is it bad practice to use python's getattr extensively?

- by Wilduck

I'm creating a shell-like environment. My original method of handleing user input was to use a dictionary mapping commands (strings) to methods of various classes, making use of the fact that functions are first class objects in python. For flexibility's sake (mostly for parsing commands), I'm thinking of changing my setup such that I'm using getattr(command), to grab the method I need and then passing arguments to it at the end of my parser. Another advantage of this approach is not having to update my (currently statically implemented) command dictionary every time I add a new method/command. My question is, will I be taking a hit to the efficiency of my shell? Does it matter how many methods/commands I have? I'm currently looking at 30 some commands, which could eventually double.

replace values in form.data when form fails validation

- by John

Hi I have a form field which requires a json object as its value when it is rendered. When the form is submitted it returns a comma seperated string of ids as its value (not a json string). however if the form does not validate i want to turn this string of ids back into a json string so it will display properly (is uses jquery to render the json object correctly). how would i do this? I was thinking of overwriting the form.clean method but when I tried to change self.data['fieldname'] I got the error 'This QueryDict instance is immutable' and when i tried to change self.cleaned_data['fieldname'] it didn't make a difference to the value of the field. Thanks

Verifying serialisation streams when used for messaging

- by Nick

I want to add distributed messaging to some applications. One target would be embedded and the other applications would be running on Windows. I'm thinking of having a connection manager, to which all of the applications would connect and communicate. I only need some simple kind of RPC mechanism. I've looked at Google Protocol Buffers, but I don't really like the idea of code generation. I'd rather use serialisation and somehow verify the format of the serialised stream. I.e. Perhaps send metadata about what the stream would contain so that each endpoint can verify it is reading the correct version. Does anyone know of any examples of this? Perhaps the message format could be read from a file which all the applications read to verify the stream format?

Emacs: adding 1 to every number made of 2 digits inside a marked region

- by WizardOfOdds

Imagine I've got the following in a text file opened under Emacs: some 34 word 30 another 38 thing 59 to 39 say 10 here 47 and I want to turn into this, adding 1 to every number made of 2 digits: some 35 word 31 another 39 thing 60 to 40 say 11 here 48 (this is a short example, my actual need is on a much bigger list, not my call) How can I do this from Emacs? I don't mind calling some external Perl/sed/whatever magic as long as the call is made directly from Emacs and operates only on the marked region I want. How would you automate this from Emacs? I think the answer I'm thinking of consist in calling shell-command-on-region and replace the region by the output... But I'm not sure as to how to concretely do this.

How to implement file transfer with Java sockets?

- by ZeKoU

Hello, I am working on a chat implementation with Java sockets. I have focused on few functionalities, like authentication, one person chat and a group chat. I was thinking about adding file transfer functionality, and I wonder what's the good practice about this. Should I have separate socket on the server with different port listening just for file transfers? Right now input and output streams that I get from server socket are binded to Scanner and PrintWriter objects respectively, so I find it hard to use that for file transfer. Any patterns you guys could recommend or give me good recommendations are very appreciated. Thanks, ZeKoU

Is there a security issue with using javascript cookies?

- by Scarface

Hey guys, another quick question for the experts. I have an alert box that displays updates processed in php to the user just like this site. I want to make it so that if the user closes the box, then it will not pop up for another 5 minutes (unless they check the messages then it will not pop up because the entries that cause the pop up are deleted in the database). On the close of the box I was thinking of giving the user a javascript cookie, since the alert box is done in javascript. I was wondering if this was a bad coding practice, since I am kind of unfamiliar with cookies and was warned against them before. If anyone has any advice or can recommend a better way, I would really appreciate it.

Term for releasing software with time dependant portions still unfinished.

- by Jeremy French

I remember a while a go on a SO podcast Jeff was talking about the bounty system and he said that they released the bounty offering code before the bounty awarding code was written as the code would not be needed for a couple of weeks. Is there a standard term for this? Agile can work in this way but it doesn’t have to. I am thinking of suggesting it to a client for something and would like to use the correct terminology along with any information backing it up as a method. Essentially the method is to release code with some functionality incomplete as the time until the incomplete functionality is needed is less that the time it will take to develop.

Advice on simple efficient way to store web form data when no db/auth required

- by ted776

Hi, I have a situation where I need to provide an efficient way to process and store comments submitted via a web form. I would normally use PHP and either MySQL or XML to store the data, but this is slightly different in that this web form will only be temporarily available in a closed LAN environment, and all i need to do is process the form data and store it a format which can be accessed by another application on the LAN (Adobe Director). Each request made by the Director app should pop the stack of data. I'm wondering how best to store the data for this type of situation as it's not something I would normally do. I'm thinking possibly storing the data in an XML file, but any advice would be great!

Registering a delegate function with an ISO C++ callback (on mono)

- by Stick it to THE MAN

I am thinking of wrapping ISO C++ code in C# class. The only problem so far is how to deal with the C++ callbacks. In .Net languages (C# and Vb.Net), I believe the callback equivalent. Sticking with C# for now, can anyone recommend a way that I can register the C# delegate functions with my ISO C++ code. The ISO C++ code is a notification library, and I want to be able to "push" the notifications to the mono framework (i.e. C# delegates in this case). My underlying assumption is that the mechanism/steps to implement this would be the same for the .Net languages - I'll just have to code the actual delegates in the .Net language of choice - is that assumption correct? Last but not the least, is the question of thread saftey. The underlying ISO C++ code that I am exposing to .Net (mono to be more specific), is both re-ntrant and thread safe - do I have to do anything "extra" to call .Net delegate from my ISO C++ code?

PHP: Grab an image from a stream (in an img tag) but if it's not there, i don't want the img tag wri

- by Gary Willoughby

I currently have code like this in a web based file called 'view_file.php' to grab an image from an internal network. <img src="put_file.php?type=<?=$TN_TYPE;?>&path=<?=$TN_PATH;?>&filename=<?=$TN_FILENAME;?>" /> The 'put_file.php' script allows access to an internal server that we don't want to expose to the internet. This script checks to see if an image is available and if it is, sends an image header and then uses readfile() to stream the image to the 'view_file.php' page. The problem is if there isn't an image available, instead of streaming a temporary 'spacer.gif' i want to not have the img tag written at all. Any Ideas how to do this? I'm thinking maybe move the img tag into the 'put_file.php' script, but how to mix strings and steams?

Easiest way to convert json data into objects with methods attached?

- by John Mee

What's the quickest and easiest way to convert my json, containing the data of the objects, into actual objects with methods attached? By way of example, I get data for a fruitbowl with an array of fruit objects which in turn contain an array of seeds thus: {"fruitbowl": [{ "name": "apple", "color": "red", "seeds": [] },{ "name": "orange", "color": "orange", "seeds": [ {"size":"small","density":"hard"}, {"size":"small","density":"soft"} ]} } That's all nice and good but down on the client we do stuff with this fruit, like eat it and plant trees... var fruitbowl = [] function Fruit(name, color, seeds){ this.name = name this.color = color this.seeds = seeds this.eat = function(){ // munch munch } } function Seed(size, density){ this.size = size this.density = density this.plant = function(){ // grow grow } } My ajax's success routine currently is currently looping over the thing and constructing each object in turn and it doesn't handle the seeds yet, because before I go looping over seed constructors I'm thinking Is there not a better way? success: function(data){ fruitbowl.length = 0 $.each(data.fruitbowl, function(i, f){ fruitbowl.push(new Fruit(f.name, f.color, f.seeds)) }) I haven't explored looping over the objects as they are and attaching all the methods. Would that work?

Using a password to generate two distinct hashes without reducing password security

- by Nevins

Hi there, I'm in the process of designing a web application that will require the storage of GPG keys in an encrypted format in a database. I'm planning on storing the user's password in a bCrypt hash in the database. What I would like to be able to do is to use that bCrypt to authenticate the user then use the combination of the stored bCrypt hash and another hash of the password to encrypt and decrypt the GPG keys. My question is whether I can do this without reducing the security of the password? I was thinking I may be able to use something like an HMAC-SHA256 of a static string using the password and a salt as the secret key. Is there a better way to do this that I haven't thought of? Thanks

SQL: without a cursor, how to select records making a unique integer id (identity like) for dups?

- by Dr. Zim

If you have the select statement below where the PK is the primary key: select distinct dbo.DateAsInt( dateEntered) * 100 as PK, recordDescription as Data from MyTable and the output is something like this (the first numbers are spaced for clarity): PK Data 2010 01 01 00 New Years Day 2010 01 01 00 Make Resolutions 2010 01 01 00 Return Gifts 2010 02 14 00 Valentines day 2010 02 14 00 Buy flowers and you want to output something like this: PK Data 2010 01 01 01 New Years Day 2010 01 01 02 Make Resolutions 2010 01 01 03 Return Gifts 2010 02 14 01 Valentines day 2010 02 14 02 Buy flowers Is it possible to make the "00" in the PK have an "identity" number effect within a single select? Otherwise, how could you increment the number by 1 for each found activity for that date? I am already thinking as I type to try something like Sum(case when ?? then 1 end) with a group by.

Proper way to have an endless worker thread?

- by Neil N

I have an object that requires a lot of initialization (1-2 seconds on a beefy machine). Though once it is initialized it only takes about 20 miliseconds to do a typical "job" In order to prevent it from being re-initialized every time an app wants to use it (which could be 50 times a second or not at all for minutes in typical usage), I decided to give it a job que, and have it run on its own thread, checking to see if there is any work for it in the que. However I'm not entirely sure how to make a thread that runs indefinetly with or without work. Here's what I have so far, any critique is welcomed private void DoWork() { while (true) { if (JobQue.Count > 0) { // do work on JobQue.Pop() } else { System.Threading.Thread.Sleep(50); } } } After thought: I was thinking I may need to kill this thread gracefully insead of letting it run forever, so I think I will add a Job type that tells the thread to end. Any thoughts on how to end a thread like this also appreciated.

How can I support conditional validation of model properties

- by Jeff

I currently have a form that I am building that needs to support two different versions. Each version might use a different subset of form fields. I have to do this to support two different clients, but I don't want to have entirely different controller actions for both. So, I am trying to come up with a way to use a strongly typed model with validation attributes but have some of these attributes be conditional. Some approaches I can think of is similar to steve sanderson's partial validation approach. Where I would clear the model errors in a filter OnActionExecuting based on which version of the form was active. The other approach I was thinking of would to break the model up into pieces using something like class FormModel { public Form1 Form1Model {get; set;} public Form2 FormModel {get; set;} } and then we would validate appropriately depending on

Building a wiki like data model in rails question.

I have a data model in which I would like to have an item that has a description that can be edited. I would like to also keep track of all edits to the item. I am running into issues with my current strategy, which is: class Item < ActiveRecord::Base has_one :current_edit, :class_name => "Edit", :foreign_key => "current_edit_id" has_many :edits end class Edit < ActiveRecord::Base belongs_to :item end Can the Item have multiple associations to the same class like this? I was thinking that I should switch to keeping track of the edit version in the Edit object and then just sorting the has_many relationship base on this version.
