• More than 5 custom variables across multiple websites using Google Analytics

  - by brakes

  We have multiple websites using the same Google Analytics account number so we can track visitors across multiple websites. One of these websites has set 5 custom variables. We want to introduce a new custom variable to track logged in users for our single sign-on (SSO) system to find out what parts of which website they are accessing. Is this possible or is it a case that all the custom variables have been used up by 1 of the sites?

• MySQL – Introduction to User Defined Variables

  - by Pinal Dave

  MySQL supports user defined variables to have some data that can be used later part of your query. You can save a value to a variable using a SELECT statement and later you can access its value. Unlike other RDBMSs, you do not need to declare the data type for a variable. The data type is automatically assumed when you assign a value. A value can be assigned to a variable using a SET command as shown below SET @server_type:='MySQL'; When you above command is executed, the value, MySQL is assigned to the variable called @server_type. Now you can use this variable in the later part of the code. Suppose if you want to display the value, you can use SELECT statement. SELECT @server_type; The result is MySQL. Once the value is assigned it remains for the entire session until changed by the later statements. So unlike SQL Server, you do not need to have this as part the execution code every time. (Because in SQL Server, the variables are execution scoped and dropped after the execution). You can give column name as below SELECT @server_type AS server_type; You can also SELECT statement to DECLARE and SELECT the values for a variable. SELECT @message:='Welcome to MySQL' AS MESSAGE; The result is Message -------- Welcome to MySQL You can make use of variables to effectively apply many logics. One of the useful method is to generate the row number as shown in this post MySQL – Generating Row Number for Each Row using Variable.

• Need help eliminating dead code paths and variables from C source code

  - by Anjum Kaiser

  I have a legacy C code on my hands, and I am given the task to filter dead/unused symbols and paths from it. Over the time there were many insertions and deletions, causing lots of unused symbols. I have identified many dead variables which were only being written to once or twice, but were never being read from. Both blackbox/whitebox/regression testing proved that dead code removal did not affected any procedures. (We have a comprehensive test-suite). But this removal was done only on a small part of code. Now I am looking for some way to automate this work. We rely on GCC to do the work. P.S. I'm interested in removing stuff like: variables which are being read just for the sake of reading from them. variables which are spread across multiple source files and only being written to. For example: file1.c: int i; file2.c: extern int i; .... i=x;

• How should I group these variables?

  - by stariz77

  I have a shape that will be defined by: char s_type; char color; double height; double width; These variables are scanned in from a request string sent to my server and passed into my printing function, which then prints out the shape. Currently they are just local variables sitting in my main(); however, I was wondering if there would be any advantage in creating a struct containing these variables, and then passing the struct to my printing function? or how else might I improve my program's structure/style, would passing a struct by reference have any kind of performance benefit if there were many requests and therefore many printing function calls? printer(char st, char cr, double ht, double wd); int main() { // Other main functionality. char s_type; char color; double height; double width; sscanf (serv_req, "GET /%c/%c/%lf/%lf", &s_type, &color, &height, &width); printer(s_type, color, height, width); // Other main functionality. return 0; } It seemed "neater" if I had a struct or something that didn't leave me with declarations in the middle of everything else going on in main. I'm interested in structure/style as well as performance. EDIT: didn't mean to put printer declaration inside main.

• What does it mean to say "Instance variables are not over-rided" in java?

  - by Ankit

  I am aware of the concept called field hiding in java. But still I am having a confusion in relation to instance variable being not over-ridden. According to my present knowledge, overriding a method of super-class means that the JVM will call the sub-class's over-ridden method though the super-class's method is available to the sub-class. And I read the similar thing for field hiding via the link:- Hiding Fields So, in any case we are over-ridding the instance if we change the values of the inherited instance variable in the sub-class. I am confused please help. I am using the following super-class:- public class Animal{ File picture; String food; int hunger; int width, height; int xcoord, ycoord; public void makeNoise(){ ......... } public void eat(){ ............. } public void sleep(){ .......... } public void roam(){ ............. } } It has sub-classes like Tiger, cat, dog,hippo etc. The sub-classes over-ride the makeNoise(), eat and roam() method. But each sub-class also uses a different set of values for instance variables. So as per my confusion, I am kind-of overriding all the instance variables and 3 methods of the super-class Animal; and I still have the super-class instance variables available to the sub-class with the use of the super keyword.

• How can I pass environment variables to a WSGI script, using uWSGI?

  - by orokusaki

  I've added the following line to /etc/environment: FOO_DEPLOYMENT_ENV="vbox" Upon logging in via SSH, I can echo $FOO_DEPLOYMENT_ENV and, of course, see vbox output to the shell. If I open a Python shell and run os.getenv('FOO_DEPLOYMENT_ENV'), it will return 'vbox', but the same code in my Python application, when run by uWSGI (as the www-data user), it does not see the environment variable. Clearly, this isn't a problem of uWSGI, and is rather a problem with my understanding of environment variables, or how they're properly set, and the contexts in which they can be retrieved. What am I doing or understanding incorrectly?

• var in C# - Why can't it be used as a member variable?

  - by David Neale

  Why is it not possible to have implicitly-typed variables at a class level within C# for when these variables are immediately assigned? ie: public class TheClass { private var aList = new List<string>(); } Is it just something that hasn't been implemented or is there a conceptual/technical reason for why it hasn't been done?

• Analysing Group & Individual Member Performance -RUP

  - by user23871

  I am writing a report which requires the analysis of performance of each individual team member. This is for a software development project developed using the Unified Process (UP). I was just wondering if there are any existing group & individual appraisal metrics used so I don't have to reinvent the wheel... EDIT This is by no means correct but something like: Individual Contribution (IC) = time spent (individual) / time spent (total) = Performance = ? (should use individual contribution (IC) combined with something to gain a measure of overall performance).... Maybe I am talking complete hash and I know generally its really difficult to analyse performance with numbers but any mathematicians out there that can lend a hand or know a somewhat more accurate method of analysing performance than arbitrary marking (e.g. 8 out 10)

• What Is The Relationship Between Software Architect and Team Member

  - by Steve Peng

  I work for a small company which has less than 100 persons. Several months ago, this company offered me position of SA and I accepted. There are three teams in this company, and I work for one of them. This is the first time I work as a SA. During the past months, I find I don't have any power of management, I even can't let the team member do things (coding-related) in the way which is correct and more efficient. The team members argue with me on very very basic technical questions and I have to explain to them again and again. Though some members did take my advice, other members stubbornly program in their way which frequently proved wrong finally. Recently I feel a little tired and confused. I wonder what is correct relationship between a Software Architect and team members including the team leader? Besides, is software architect also leaded by the Team Leader?

• Unable to Call Instantiate in Class Member Function

  - by onguarde

  The following javascript is attached to a gameObject. var instance : GameObject; class eg_class { function eg_func(){ var thePrefab : GameObject; instance = Instantiate(thePrefab); } } Error, Unknown identifier: 'instance'. Unknown identifier: 'Instantiate'. Questions, 1) Why is it that "instance" cannot be accessed within a class? Isn't it supposed to be a public variable? 2) "Instantiate" function works in Start()/Update() root functions. Is there a way to make it work from within member functions? Thanks in advance!

• Unity 3D - Error BCE0019 , " 'paused' is not a member of PauseScript"

  - by user3666251

  I am trying to make a game for Android in Unity. Came to the part where I have to make a pause menu option. Made a GUITexture and placed it on the top right side of the screen then I attached this script to it : #pragma strict function OnMouseDown(){ this.paused = !this.paused; } function OnGUI(){ if(this.paused){ if (GUI.Button(Rect(10,10,100,50),"Restart")){ Application.LoadLevel(Application.loadedLevel); } // Insert the rest of the pause menu logic } } It gives me this error : "Assets/Scripts/PauseScript.js(4,10): BCE0019: 'paused' is not a member of 'PauseScript'. " "PauseScript" is the name of my pause script. Thank you.

• C++: Copy contructor: Use Getters or access member vars directly?

  - by cbrulak

  Have a simple container class: public Container { public: Container() {} Container(const Container& cont) //option 1 { SetMyString(cont.GetMyString()); } //OR Container(const Container& cont) //option 2 { m_str1 = cont.m_str1; } public string GetMyString() { return m_str1;} public void SetMyString(string str) { m_str1 = str;} private: string m_str1; } So, would you recommend this method or accessing the member variables directly? In the example, all code is inline, but in our real code there is no inline code. Update (29 Sept 09): Some of these answers are well written however they seem to get missing the point of this question: this is simple contrived example to discuss using getters/setters vs variables initializer lists or private validator functions are not really part of this question. I'm wondering if either design will make the code easier to maintain and expand. Some ppl are focusing on the string in this example however it is just an example, imagine it is a different object instead. I'm not concerned about performance. we're not programming on the PDP-11

• NullReferenceException when accessing variables in a 2D array in Unity

  - by Syed

  I have made a class including variables in Monodevelop which is: public class GridInfo : MonoBehaviour { public float initPosX; public float initPosY; public bool inUse; public int f; public int g; public int h; public GridInfo parent; public int y,x; } Now I am using its class variable in another class, Map.cs which is: public class Map : MonoBehaviour { public static GridInfo[,] Tile = new GridInfo[17, 23]; void Start() { Tile[0,0].initPosX = initPosX; //Line 49 } } I am not getting any error on runtime, but when I play in unity it is giving me error NullReferenceException: Object reference not set to an instance of an object Map.Start () (at Assets/Scripts/Map.cs:49) I am not inserting this script in any gameobject, as Map.cs will make a GridInfo type array, I have also tried using variables using GetComponent, where is the problem ?

• Clean Code says to avoid protected variables

  - by Matsemann

  I have a question to a statement in Clean Code. I don't fully understand the reasoning to why we should avoid protected variables. It's from the chapter about Formatting, section about Vertical Distance: Concepts that are closely related should be kept vertically close to each other. Clearly this rule doesn't work for concepts that belong in separate files. But then closely related concepts should not be separated into different files unless you have a very good reason. Indeed, this is one of the reasons that protected variables should be avoided.

• Missed environment variables in Eclipse Juno

  - by hara

  I recently moved from Eclipse Indigo to Juno. I installed the IDE in my Ubuntu 12.04 by downloading the archive from here. Then I created an entry in the unity launcher for Juno as I done before for Indigo. Here is what I wrote in ~/.local/share/applications/eclipse-juno.desktop: [Desktop Entry] Type=Application Name=Eclipse Juno Comment=Eclipse Integrated Developmentm Environment Icon=~/.eclipse-juno/icon.xpm Exec=~/.eclipse-juno/eclipse -vmargs -Duser.name="my name" Terminal=false Categories=Development;IDE;Java; When I run eclipse from the unity launcher, eclipse does not see environment variables that I set in ~/.bascrc. Instead, if I run eclipse from shell, it can see all the env variables. How can I fix the problem? Thanks a lot.

• Naming conventions used for variables and functions in C

  - by Zel

  While coding a large project in C I came upon a problem. If I keep on writing more code then there will be a time when it will be difficult for me to organize the code. I mean that the naming for functions and variables for different parts of the program may seem to be mixed up. So I was thinking whether there are useful naming conventions that I can use for C variables and functions? Most languages suggest a naming convention. But for C the only thing I have read so far is the names should be descriptive for code readability. EDIT: Examples of some examples of suggested naming conventions: Python's PEP 8 Java Tutorial I read some more naming conventions for java somewhere but couldn't remember where.

• SSIS 2008 Configuration Settings Handling Logic for Variables Visualized

  - by Compudicted

  There are many articles discussing the specifics of how the configuration settings are applied including the differences between SSIS 2005 and 2008 version implementations, however this topic keeps resurfacing on MSDN’s SSIS Forum. I thought it could be useful to cover the logic aspect visually. Below is a diagram explaining the basic flow of a variable setting for a case when no parent package is involved.   As you can see the run time stage ignores any command line flags for variables already set in the config file, I realize this is not stressed enough in many publications. Besides, another interesting fact is that the command line dtexec tool is case sensitive for the portion following the package keyword, I mean if you specify your flag to set a new value for a variable like dtexec /f Package.dtsx -set \package.variables[varPkgMyDate].value;02/01/2011 (notice the lover case v in .value) You will get errors. By capitalizing the keyword the package runs successfully.

• How to access variables of uninitialized class?

  - by oringe

  So I've gone with a somewhat singleton approach to my game class: #include "myGame.h" int main () { myGame game; return game.Execute(); } But now I need to define a class that accesses variables in the instance of myGame. class MotionState { public: virtual void setWorldTransform (...) { VariableFromMyGameClass++; //<-- !? ...} }; I'm trying to integrate this class into my project from an example that just uses globals. How can I access variables of myGame class in the definition of new classes? Should I give up on my singleton approach?
