  • Are parametrized calls/sanitization/escaping characters necessary for hashed password fields in SQL queries?

    - by Computerish
    When writing a login system for a website, it is standard to use some combination of parameterized calls, sanitizing the user input, and/or escaping special characters to prevent SQL injection attacks. Any good login system, however, should also hash (and possibly salt) every password before it goes into an SQL query, so is it still necessary to worry about SQL injection attacks in passwords? Doesn't a hash completely eliminate any possibility of an SQL injection attack on its own?

  • Redundant code constructs

    - by Diomidis Spinellis
    The most egregiously redundant code construct I often see involves using the code sequence if (condition) return true; else return false; instead of simply writing return (condition); I've seen this beginner error in all sorts of languages: from Pascal and C to PHP and Java. What other such constructs would you flag in a code review?

  • why do you write tests and what is a unit test and how does it differ other types of testing ?

    - by dfafa
    im curious as to know, why tests are written? why would bother writing it ? why not just compile and run the code or view it in your browser, click around and test out stuff. i mean i can understand, a crawler that checks your web app's functions....but why is tests written, maintained and treated as important as the main feature codes ? is it crucial to always write and use tests ?

  • How do I get the Virtual Machines folder on Win7?

    - by xpmore
    I'm writing a tool called XP-More, which should help manage Windows 7 Virtual Machines. The first thing the tool has to do when launched is find the VM folder. However, turns out that folder is not listed as a Windows Special Folder. I use a workaround, but it's unreliable. Ideally, Environment.GetFolderPath(Environment.SpecialFolder.VMFolder) or so would have done the job, but VMFolder is a fiction of my imagination. Is there any real way to get that folder?

  • Should I bother with C++ or go straight to C#?

    - by Pat Riley
    I have been writing embedded C applications for almost 20 years. In the last few years I have written quite a few PC based GUI interfaces in Visual C so I could interface my embedded systems to a PC. Although my primary work will still be in deeply embedded C, I have finally decided to move my PC based tools into Ruby - (for quick scripting type stuff) and C++ or C# for GUI based interfaces and applications. Should I bother with C++ or just move straight to C#?

  • Delphi, read data from 3rd party data field

    - by donaldadams1951
    I am writing an application that needs to read a data field on another Delphi program and I do not have access to the source code of the 3rd party program. The data field contains the "foreign key" to a record I need to retrieve or create in my application. I would appreciate any links to knowledge or components that will help me with my program.

  • Use the keyword class as a variable name in C++

    - by Leif Andersen
    I am having trouble writing C++ code that uses a header file designed for a C file. In particular, the header file used a variable name called class: int BPY_class_validate(const char *class_type, PyObject *class, PyObject *base_class, BPY_class_attr_check* class_attrs, PyObject **py_class_attrs); This works in C as class isn't taken as a keyword, but in C++, class is. So is there anyway I can #include this header file into a c++ file, or am I out of luck? Thank you.

  • What is the fastest / best Base64 en/decoder for Java ?

    - by mP
    Just found the MIG Base 64 utility but its over 6 years old since its last release. It would appear to be quicker than the Apache commons equivalent but I have yet to confirm by writing up an actual test. Has anyone verified its correctness which is always a worry. If someone takes a look at the methods, please note i a referring to the non fast methods which make assumptions trading possible correctness for pure speed.

  • Getting path of file copied after deployment in a unit test C#

    - by amitchd
    Hi, The connection string in my app.config for my C# project looks like Data Source=.\SQLEXPRESS;AttachDbFilename='|DataDirectory|\EIC.mdf';Integrated Security=True;User Instance=True" I am writing unit tests for the project and have the set the test run configuration to copy the EIC.mdf, but I do am not able to reference the Deployed copy of EIC.mdf to be referenced by the app.config I created for the test project. If I set it to Data Source=.\SQLEXPRESS;AttachDbFilename='EIC.mdf';Integrated Security=True;User Instance=True" It still does not find the mdf file.

  • Class definition thinks setting a variable is a Unit?

    - by DeLongey
    Writing out a Scala class and problem here is that the compiler thinks that the code is a unit not returning the proper value. It's a method used to set a property in the class: def setObject(`object`:StripeObject):StripeObject = { this.`object` = `object` } The error is: type mismatch; found : Unit required: com.stripe.StripeObject The full class is: case class EventData(var previousAttributes: HashMap[String,Object], var `object`:StripeObject) extends StripeObject { def getPreviousAttributes = { previousAttributes } def setPreviousAttributes(previousAttributes: HashMap[String, Object]) = { this.previousAttributes = previousAttributes } def getObject = { `object` } def setObject(`object`:StripeObject):StripeObject = { this.`object` = `object` } } How do I make sure it doesn't return a Unit?

  • How do I move my git repo down level in the directory tree?

    - by edude05
    I'm currently writing an app in C# using using Visual Studio. As such, VS2010 created a Solution directory with my project directories inside. So my Hierarchy is like this: Solution .git project1 project2 What I'd like to do is make it like this: Solution Project 1 .git Project 2 As of right now the files in the solution are tracked, except for the project 2 (so stuff like project.sln for example). Is there a way I can do this without rewriting the history? Thanks in advance.

  • Javascript: How to detect if a word is highlighted

    - by fterh
    I'm writing a Firefox addon that is triggered whenever a word is highlighted. However I need a script that detects when a word is highlighted, and I'm stuck. An example would be nytimes.com (when you're reading an article and you highlight a word, the reference icon pops up). However the nytimes.com script is super complex. I'm 16 and not much of a programmer, so that is definitely way out of my league.

  • How to notify a Windows .net service from PHP on Linux?

    - by Louis Haußknecht
    I'm writing a service in C# on Windows which should be triggert by an PHP driven web frontend, which runs on Linux. Both processes share the same SQL Server 2005 database. There is no messaging middleware available atm. The PHP process inserts an row in a SQL Server table. The Windows process should read this entry and process it. I have no experience in PHP, so what would you suggest to notify the Windows process?

  • C++ Logger-Should I use an ordinary xml parser?

    - by Jonathon
    I'm working on a logging system for my 2D engine, and I'm confused on how I should go about creating/editing the file, and how I should output that file. I've learned that XML is more of a data carrier rather than a data displayer like HTML is. I've read that I can use XML to HTML converters. One method I've thought about is writing characters to a file in HTML. Clarity on these matters is what I ask of you, stack overflow.
