• DLL search on windows

  - by Luís Guilherme

  On linux, we have LIBRARY_PATH and LD_LIBRARY_PATH environment variables in order for programs to search for libraries. Do we have similar thing on windows? Particularly Windows 7? Also, I would like to know best practices for DLL use (where to put them, use envs or not, etc.), since I want to work on windows like everyone does, and not to sloth myself on workarounds :)

• How can I trace a variable at runtime in C#?

  - by luvieere

  How can I track a variable's values as they change, at runtime, in C#? I'm interested in the same functionality that the debugger provides when I'm tracing a variable through execution steps, only that I need to call upon it from my code. Some sort of key-value observing, but for all kinds of variables(local, class, static, etc), not only properties. So, basically, receive a notification when a variable's value changes.

• set windows PATH environment variable at runtime in Java

  - by hhhh

  I have a java program that fires off an executable using the Runtime.exec() method. I'm using the variant that takes in a set of command line params as one argument, and some environment variables as another argument. The environment variable I'm tryign to set is path, so i'm passing in "PATH=C:\some\path". This does not work. Is there some trick to this or any alternatives. I am stuck to Java 1.4 unfortunately.

• C variable declarations after function heading in definition

  - by Yktula

  When reading some FreeBSD source code (See: radix.h lines 158-173), I found variable declarations that followed the "function heading" in the definition. Is this valid in ISO C (C99)? when should this be done in production code instead of just declaring the variables within the "function heading?" Why is it being done here? I refer to the function heading the string that looks like this: int someFunction(int i, int b) {

• Javascript, language files, configuration

  - by johnnyArt

  I'm building a form validation script for one of my sites, and I thought I'd make the error messages international, meaning that depending on the users language I'd give such or such response. What would the best approach be, for loading a configuration file inside of my class? Right now I'm using the following structure for a single language: const config = { 'errorName' : 'error message', 'errorName2' : 'error message', 'errorName2' : 'error message' } And calling it like this of course: config['errorName']. But I don't know how to load those variables from a file, let's say 'lang/en.js'

• How do I call setattr() on the current module?

  - by Matt Joiner

  What do I pass as the first parameter "object" to the function setattr(object, name, value), to set variables on the current module? For example: setattr(object, "SOME_CONSTANT", 42); giving the same effect as: SOME_CONSTANT = 42 within the module containing these lines (with the correct object). I'm generate several values at the module level dynamically, and as I can't define __getattr__ at the module level, this is my fallback.

• Python dictionary to variable assignments based on key value to variable name

  - by Art

  Basically, I want to take a Dictionary like { "a":"bar", "b":"blah", "c":"abc", "d":"nada" } and use it to set variables (in an Object) which have the same name as a key in the dictionary. class Foo(Object) { self.a = "" self.b = "" self.c = "" } So in the the end self.a = "bar", self.b = "blah", etc... (and key "d" is ignored) Any ideas?

• Auto-Completion in Unix VI editor

  - by IllustratedInsomnia

  Hey guys, after using graphical IDE's like Visual Studio, I'm used to pressing CTRL+Space to auto-complete a variable or function name. Now, I know such a thing isn't completely possible in VI, but I heard there was a list of commands that could be mapped that allowed automatic completion of variables and functions in the current file opened. Does anyone know what this sequence is? Thanks in advance.

• What is the naming convention in Python for variable and function names?

  - by Ray Vega

  Coming from a C# background the naming convention for variables and method names are usually either CamelCase or Pascal Case: // C# example string thisIsMyVariable = "a" public void ThisIsMyMethod() In Python, I have seen the above but I have also seen underscores being used: # python example this_is_my_variable = 'a' def this_is_my_function(): Is there a more preferable, definitive coding style for Python?

• What's the scope of a Python variable declared in an if statement?

  - by froadie

  I'm new to Python, so this is probably a simple scoping question. The following code in a Python file (module) is confusing me slightly: if __name__ == '__main__': x = 1 print x In other languages I've worked in, this code would throw an exception, as the x variable is local to the if statement and should not exist outside of it. But this code executes, and prints 1. Can anyone explain this behavior? Are all variables declared in a module global/available to the entire module?

• Allowed characters in linux environment variable names

  - by Christian Semrau

  What characters are allowed in linux environment variable names? My cursory search of man pages and the web did only produce information about how to work with variables, but not which names are allowed. I have a Java program that requires an defined environment variable containing a dot, like com.example.fancyproperty. With Windows I can set that variable, but I had no luck setting it in linux (tried in SuSE and Ubuntu). Is that variable name even allowed?

• What is the origin / meaning of these variable naming conventions?

  - by Andrew Hubbs

  What is the general meaning and where did it start to have variables with leading or trailing underscores? ex: _varName and varName_ I have always thought a leading underscore indicated the variable was a pointer but I don't know where I got this idea. Recently I have seen these naming conventions used in Java which makes that reasoning completely wrong.

• Zend_Registry: real life examples

  - by takeshin

  Do you find Zend_Registry useful? For which tasks it should be used? For which not? Global state for variables is not a good practice. Main objects may have global state injected via $front->setParam('paramName', $object), so what's the purpose of Zend_Registry?.

All it does is unpack a target tar, and then i want to permanently set some environment variables - principally the location of the unpacked libs and updating $PATH.

• Using the same variable across multiple files in C++

  - by Sam152

  In the process of changing some code, I have spilt some functions into multiple files. I have the files controls.cpp and display.cpp and I would like to be able to have access to the same set of variables in both files. I don't mind where they are initialized or declared, as long as the functions in both files can use them. This was not an issue when the functions were in the same file, but now it seems almost impossible after an hour of googling and trying various things.

• Assign query results to MySQL variable

  - by 5un5

  I'm querying a big mysql database with only read privileges, and I'd like to set some slow query results to a variable, 'foo', so I can use them again in other queries. I get, ERROR 1193 (HY000): Unknown system variable '$foo' when I enter: set $foo := (select * from table1 join table2 where bar = 0 group by id); Is there a way to do this with variables, since I don't have privileges to create temporary tables?
