  • Essential Programming Tools

    - by Mat
    We all have different needs due to the platform and/or stack we work with, and simple programmer preference is famous for starting religious wars. However, in each area there is usually a set of tools that get recommended over and over, even though people might individually prefer one member over the others. Unix text mode code editors, for example, is an extremely contentious issue but no one can deny that most people will choose either vi or emacs. So, without criticising the alternatives, recommend me developement tools. Text editors for different platforms, version control systems, bug trackers, database engines, templating systems... whatever! What do you enjoy using every day? I'll edit together the answers as a list of highly recommended tools in each area. Please don't start discussing which is the best ;)

  • Use only some parts of Django?

    - by Hanno Fietz
    I like Django, but for a particular application I would like to use only parts of it, but I'm not familiar enough with how Django works on the inside, so maybe someone can point me into the right direction as to what I have to check out. Specifically, I want to use: The models and database abstraction The caching API, although I want to avoid database lookups by caching, not HTML generation, and since the caching framework in Django is intended for the latter, I'm not sure yet whether that's really appropriate. I would not use: Templating urlconfigs Or, more exactly, I'm neither using HTTP nor HTML. So basically, I have a different input / output chain than usual. Can this work? My personal killer feature in Django is the Object / database mapping that I can do with the models, so if there's another technology (doesn't have to be Python, I'm in the design phase and I'm pretty agnostic about languages and platforms) that gives me the same abilities, that would be great, too.

  • ASP.NET MVC Session usage

    - by Ben
    Currently I am using ViewData or TempData for object persistance in my ASP.NET MVC application. However in a few cases where I am storing objects into ViewData through my base controller class, I am hitting the database on every request (when ViewData["whatever"] == null). It would be good to persist these into something with a longer lifespan, namely session. Similarly in an order processing pipeline, I don't want things like Order to be saved to the database on creation. I would rather populate the object in memory and then when the order gets to a certain state, save it. So it would seem that session is the best place for this? Or would you recommend that in the case of order, to retrieve the order from the database on each request, rather than using session? Thoughts, suggestions appreciated. Thanks Ben

  • ASP.NET connection pool question

    - by James Evans
    Does the same connection string used on two different physical servers hosting different web applications that talk to the same database draw connections from the same connection pool? Or are pooled connections confined to at the application level? I ask because I inherited a 7 year old .NET 1.1 web application which is riddled with in-line SQL, unclosed and undisposed sql connection and datareader objects. Recently, I was tasked to write a small web app that is hosted on another server and talks to the same database and therefore used the same database connection string. I created a LINQ object to read and write the one table required by the app. Now the original .NET 1.1 app is throwing exceptions like "Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached." Maybe these are unreleated, but wanted to get your opinions to make sure I cover all my bases. Thanks!

  • SQL Server compatibility mode not logged

    - by smithsi
    I've been researching a problem which was diagnosed as someone changing the compatability mode for the SQL Server database from 80 to 90 on SQL Server 2005 for a database which had it's compatibility mode set to 80 due to legacy stored procedure code not having been upgraded. I found that when changing the compatibility mode this is not logged in the SQL Server logs. Has anyone seen this issue and is this a bug or is there an alternative method to track these changes?

  • How to automatically change a parameter in Reporting Services when another is changed?

    - by Victor Rodrigues
    I have a 'Product' parameter in my report. Depending on the product the user chooses, it will call the report generator stored procedure from a different data source. Looking at this article, I've found how to do the first part of this solution. I've created two internal parameters, Server and Database, and the connection string will use them to connect to the right database. But I need to set this two parameters when the user chooses a product. How could I do this? (If @Product = X) = @Server = Y, @Database = Z

  • Backing up MySQL DB wtih mixture of innodb and myisam tables

    - by madphp
    I have a large database (almost 1GB) and it has a mixture of innodb and myisam tables. Does anyone have any general tips when backing it up or more specifically the commands i should send to mysqldump. I see that i should lock myisam tables, and that single transactions for innodb, but what if i have both. Also, what is actually happening when i lock an entire (very big) table on a production database.

  • What do you use for recurring payments in a Rails Application?

    - by Chance
    I'm fairly new to rails so I'm definitely not up to speed on the community's best practices, tools, etc. So I figure this may be the best place to ask. What do you use for recurring billing in a rails app? From what I can tell, there are a number of options including rolling my own with ActiveMerchant or using one of the SaaS out there. As far as the SaaS recurring billing systems, I've only stumbled upon one thus far (chedder getter) and I'm hoping there are alternatives (if, for nothing else, so I can compare). Additionally, I've seen a few invoice systems but they either do not handle the payment portion, do not seem to fit well with the intention, or are extremely outdated. Thanks in advance!

  • at what point in the test cycle are the test results written to a file?

    - by jcollum
    I'd like to take the entirety of the test results and publish it to a database. Got the database, got the table, got the script to publish it. Question is, at what point in the ms-test cycle would the results be fully written to the file? And how can I get the path to that file? I'd especially like to grab the "TextMessages" node and put it into my database. I assumed AssemblyCleanup, but the TestContext doesn't seem to be available then.

  • Web app - Biometric system connection

    - by DMin
    Hi, I will be developing an application for a club where they will have visitors use biometric systems(finger print) or magnetic cards to mark their attendance. This application is planned as a web app, made using PHP/MySQL/Javascript. It does a lot of other things as well. What I wanted to find out is how is the interface between Biometric/Megnetic Card systems to a web app done? I've never worked on this and am hoping if someone who has experience with this can throw some light on this as to how this could be accomplished. Any pointers will be appreciated. (I'm afraid there's got to be some form of application installed on a pc that would interface with the hardware and probably makes calls to the web app. But, if there was a way to connect it to the web app directly, then the app would be easy to deploy to any location with minimal installation.) Thanks! :)

  • Best practice. Do I save html tags in DB or store the html entity value?

    - by Matt
    Hi Guys, I was wondering about which way i should do the following. I am using the tiny MCE wysiwyg editor which formats the users data with the right html tags. Now, i need to save this data entered into the editor into a database table. Should I encode the html tags to their corresponding entities when inserting into the DB, then when i get the data back from the table, not have the encode it for XSS purposes but I'd still have to use eval for the html tags to format the text. OR Do i save the html tags into the database, then when i get the data back from the database encode the html tags to their entities, but then as the tags will appear to the user, I'd have to use the eval function to actually format the data as it was entered. My thoughts are with the first option, I just wondered on what you guys thought.

  • How to change a Datasource's username/password at runtime in a J2EE app?

    - by Toto
    I've deployed a web-module which connects to the database via a datasource configured in the J2EE application server. Currently, the user/password for the database connection is set in the proper J2EE application server's datasources configuration file. I want to change during runtime the datasource's user/password. (e.g.: implement a new web form in which the user is asked to enter de user/password to be used in the database connection). Is there a standard way to do that in J2EE applications or it depends on the J2EE application server? In this case I'm using Orion application server.

  • updating batches of data

    - by gaponte69
    I am using GridView in asp .net and editing data with edit command field property (as we know after updating the edited row, we automatically update the database), and I want to use transactions (with begin to commit statement - including rollback) to commit this update query in database, after clicking in some button (after some events for example), not automatically to insert or update the edited data from grid directly to the DB...so I want to save them somewhere temporary (even many edited rows - not just one row) and then to confirm the transaction - to update the real tables in database... Any suggestions are welcomed... I've used some good links, but very helpful, like: http://www.asp.net/learn/data-access/tutorial-63-cs.aspx http://www.asp.net/learn/data-access/tutorial-66-cs.aspx etc...

  • Dollar ($) sign in password string treated as variable

    - by ncatnow
    Spent some time troubleshooting a problem whereby a PHP/MySQL web application was having problems connecting to the database. The database could be accessed from the shell and phpMyAdmin with the exact same credentials and it didn't make sense. Turns out the password had a $ sign in it: $_DB["password"] = "mypas$word"; The password being sent was "mypas" which is obviously wrong. What's the best way to handle this problem? I escaped the $ with a \ $_DB["password"] = "mypas\$word"; and it worked. I generally use $string = 'test' for strings which is probably how I avoided running into this before. Is this correct behavious? What if this password was stored in a database and PHP pulled it out - would this same problem occur? What am I missing here...

  • Idiomatic way to read .env variables in Ansible?

    - by Arms
    I'm provisioning a Vagrant box with Ansible, and using Benno Joy's MySQL role to setup MySQL (including creating a database and users.) The database name and credentials are stored in a .env file in the project's root. What would be the idiomatic way to use these variables when provisioning MySQL? Should I write a custom script that generates a YAML file from my .env, and then use the include_vars module? Or is there a simpler way?

  • Schema changes with replication

    - by Even Mien
    What are the steps to make a schema change to a SQL Server 2005 database using transactional replication? I'm trying to add a database column. I thought if I removed the article for the table, made the schema change, and then added the article for the table back that the schema change would replicate. I am now getting the following error every minute or so: SQL Server errors Replication-Replication Distribution Subsystem: agent [jobname] failed. Invalid column name 'NewColumn'.

  • Excel File opened under Ubuntu, read by R, OpenOffice

    - by Vishal Belsare
    I have a bunch of Excel files which are updated on a daily basis on a Windows machine. I transfer them to a Ubuntu machine and want to open them there. Specifically, I want to read the files as a database under R. A couple years ago, I used ODBC under a Windows machine to open Excel files through R. Is there any way, I can do this with R under Ubuntu? I could make a database .ODB file for the corresponding XLS files using OpenOffice, but I don't know of a way to connect to a .ODB database. OpenOffice seems to have ways to connect TO databases, but no way to connect to ODB. Thanks for any potential solutions.

  • How to programmatically change a data cell of Ms Access using VB.Net?

    - by manuel
    I have a Microsoft Access database file connected to VB.NET. In the database table, I have a 'No.' and a 'Status' column. Then I have a textbox where I can input an integer. I also have a button, which will change the data cell in 'Status' where 'No.' = textbox.Text(), when I click it. Let's say I want the 'Status' cell to be changed to "Low". What codes should I put in the button_Click event handler? Here is the codes I used to retrieve and display the database table. Public Class theForm Dim con As New OleDb.OleDbConnection Dim ds As New DataSet Dim daTitles As OleDb.OleDbDataAdapter Private Sub theForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load con.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=|DataDirectory|\db1.mdb" con.Open() daTitles = New OleDb.OleDbDataAdapter("SELECT * FROM Titles", con) daTitles.Fill(ds, "Titles") DataGridView1.DataSource = ds.Tables("Titles") DataGridView1.AutoResizeColumns() End Sub
