  • Manipulating Directory Paths in Python

    - by G Ullman
    Basically I've got this current url and this other key that I want to merge into a new url, but there are three different cases. Suppose the current url is localhost:32401/A/B/foo if key is bar then I want to return localhost:32401/A/B/bar if key starts with a slash and is /A/bar then I want to return localhost:32401/A/bar finally if key is its own independent url then I just want to return that key = htt p://foo.com/bar - http://foo.com/bar I assume there is a way to do at least the first two cases without manipulating the strings manually, but nothing jumped out at me immediately in the os.path module.

  • Are conditional subqueries optimized out, if the condition is false?

    - by Tobias Schulte
    I have a table foo and a table bar, where each foo might have a bar (and a bar might belong to multiple foos). Now I need to select all foos with a bar. My sql looks like this SELECT * FROM foo f WHERE [...] AND ($param IS NULL OR (SELECT ((COUNT(*))>0) FROM bar b WHERE f.bar = b.id)) with $param being replaced at runtime. The question is: Will the subquery be executed even if param is null, or will the dbms optimize the subquery out? We are using mysql, mssql and oracle. Is there a difference between these regarding the above?

  • How to extract the current state of the registry? (in C/C++, XP)

    - by Doori Bar
    I was wondering how one might extract the current state of the registry, of Windows XP, in C or C++? (While the OS is active). I been trying to use BackupRead() on the registry-files, but it is impossible to CreateFile() them. I managed to create a Shadow Copy of the registry-files, but it wasn't the current state of the registry. Would appreciate any hint... (I know ERUNT is able to do it) Thanks, Doori Bar

  • With paperclip, how can I change the image location to a ":parent_model_id/:id" folder format?

    - by Jamis Charles
    Given that I have a Listing model that has many images and each image has one attachment, how can I have the listing_id be part of the folder structure? Like so: system/photos/[listing_id]/:id I know that using :id will output the id of the image record. Here's what I currently have: class Image < ActiveRecord::Base belongs_to :listing #Rails ActiveRecord Relation. An image belongs to a post. # paperclip data has_attached_file :photo, :styles => { :medium => "300x300>", :thumb => "100x100>" }, :url => "/public/system/:class/:attachment/:id/:style_:filename" end

  • Declare variables that depend on unknown type in template functions.

    - by rem
    Suppose I'm writing a template function foo that has type parameter T. It gets an object of type T that must have method bar(). And inside foo I want to create a vector of objects of type returned by bar. In GNU C++ I can write something like that: template<typename T> void foo(T x) { std::vector<__typeof(x.bar())> v; v.push_back(x.bar()); v.push_back(x.bar()); v.push_back(x.bar()); std::cout << v.size() << std::endl; } How to do the same thing in Microsoft Visual C++? Is there some way to write this code that works in both GNU C++ and Visual C++?

  • bash tools for parsing arguments

    - by BCS
    I have a bash script that uses a few variables (call them $foo and $bar). Right now the script defines them at the top with hard coded values like this: foo=fooDefault bar=barDefault .... # use $foo and $bar What I want is to be able to use the script like any of these: myscript # use all defaults myscript -foo=altFoo # use default bar myscript -bar=altBar # use default foo myscript -bar=altBar -foo=altFoo An ideal solution would allow me to just list the variable that I want to check for flags for. Is there a reasonably nice way to do this? I've seen getopt and I think it might do about 70% of what I'm looking for but I'm wondering if there is a tool or indium that builds on it or the like that gets the rest.

  • How to define a custom iterator in C++

    - by Robert Martin
    I've seen a number of posts on SO about how to define custom iterators, but nothing that seems to exactly answers my question, which is... How do I create an iterator that hides a nested for loop? For instance, I have a class Foo, inside of the Foo is a Bar, and inside of the Bar is a string. I could write for (const Foo& foo : foo_set) for (const Bar& bar : foo.bar_set) if (bar.my_string != "baz") cout << bar.my_string << endl; but instead I want to be able to do something like: for (const string& good : foo_set) cout << good << endl; How do I do something like this?

  • How do I deploy a word template solution and run it regardless of it's location?

    - by user265316
    Hi, I'm trying to deploy a Word Template solution that uses VSTO with VS2010. Everything goes well until I try to move the template file away from the folder that has the assemblies (then I get a "failed to customization error"). What is the best way to make sure that file knows where the assemblies are? Should I update the _AssemplyLocation property programatically or is there another way to do this? Thanks.

  • VS2010 (older) installer project - two or more objects have the same target location.

    - by Hamish Grubijan
    This installer project was created back in 2004 and upgraded ever since. There are two offending dll files, which produce a total of 4 errors. I have searched online for this warning message and did not find a permanent fix (I did manage to make it go away once until I have done something like a clean, or built in Release, and then in Debug). I also tried cleaning, and then refreshing the dependencies. The duplicated entries are still in there. I also did not find a good explanation for what this error means. Additional warnings are of this nature: Warning 36 The version of the .NET Framework launch condition '.NET Framework 4' does not match the selected .NET Framework bootstrapper package. Update the .NET Framework launch condition to match the version of the .NET Framework selected in the Prerequisites Dialog Box. So, where is this prerequisites box? I want to make both things agree on .Net 4.0, just having a hard time locating both of them.

  • Index a mysql table of 3 integer fields

    - by Doori Bar
    I have a mysql table of 3 integer fields. None of the fields have a unique value - but the three of them combined are unique. When I query this table, I only search by the first field. Which approach is recommended for indexing such table? Having a multiple-field primary key on the 3 fields, or setting an index on the first field, which is not unique? Thanks, Doori Bar

  • How to copy resources from other module to specific location ? (maven)

    - by smallufo
    I have a maven-managed project with some modules. One module contains some native codes inside "src/main/resources/native" directory. Second module packages all related modules to a WAR file. Here comes the question : How to copy the "native/" directory (and its sub-directories) in first module to WEB-INF/native directory in the second module ? I found a copy resources plugin , but it seems not what I want. (It copies directory inside the same module , but I want cross-module copy) Thanks in advanced.

  • int foo(type& bar); is a bad practice?

    - by Earlz
    Well, here we are. Yet another proposed practice that my C++ book has an opinion on. It says "a returning-value(non-void) function should not take reference types as a parameter." So basically if you were to implement a function like this: int read_file(int& into){ ... } and used the integer return value as some sort of error indicator (ignoring the fact that we have exceptions) then that function would be poorly written and it should actually be like void read_file(int& into, int& error){ } Now to me, the first one is much clearer and nice to use. If you want to ignore the error value, you do so with ease. But this book suggests the later. Note that this book does not say returning value functions are bad. It rather says that you should either only return a value or you should only use references. What are your thoughts on this? Is my book full of crap? (again)

  • How do I reset my pointer to a specific array location?

    - by ohtanya
    I am a brand new programming student, so please forgive my ignorance. My assignment states: Write a program that declares an array of 10 integers. Write a loop that accepts 10 values from the keyboard and write another loop that displays the 10 values. Do not use any subscripts within the two loops; use pointers only. Here is my code: #include "stdafx.h" #include <iostream> using namespace std; int main() { const int NUM = 10; int values[NUM]; int *p = &values[0]; int x; for(x = 0; x < NUM; ++x, ++p) { cout << "Enter a value: "; cin >> *p; } for(x = 0; x < NUM; ++x, ++p) { cout << *p << " "; } return 0; } I think I know where my problem is. After my first loop, my pointer is at values[10], but I need to get it back to values[0] to display them. How can I do that?

  • Apache/mod_rewrite > Tomcat encoding %26 and "&"...

    - by user293479
    Apache is the front-end to my web app then I use mod_rewrite to proxy the request to JBoss. So far this sounds pretty standard, but the problem I am having is: if I access the app directly through jboss @ http://localhost:8080/app/page?raw=foo%26bar&page=1: request.getParameter("raw") = foo&bar If I access the app through Apache @ http://localhost/foo%26bar&page=1 request.getParameter("raw") = foo So somewhere along the way, the %26 is lost and replaced with an & which chops the raw variable. This is my Apache rewrite rule. RewriteRule ^/(.*) \ http://localhost:8080/app/home?raw=$1 [L,P] The Apache access log shows: http://localhost/foo%26bar&page=1 And the rewrite log shows: http://localhost:8080/app/home?raw=foo&bar&page=1 But I want the request to be: http://localhost:8080/app/home?raw=foo%26bar&page=1 I am pretty sure that this also occurs with slashes / too so to me this is some sort of encoding issue. Is there a way to proxy the URL untouched? Can't seem to figure this one out.
