  • how to embed a webpage using wx?

    - by Giorgio Gelardi
    I need to show a webpage (a complex page with script and stuff, no static html) in a frame or something. It's for a desktop application, I'm using python 2.6 + wxPython 2.8.10.1. I need to catch some events too (mostly about changing page). I've found some samples using the webview module in a gtk application, but I couldn't have it works on wx.

  • How do I defer execution of some Ruby code until later and run it on demand in this scenario?

    - by Kyle Kaitan
    I've got some code that looks like the following. First, there's a simple Parser class for parsing command-line arguments with options. class Parser def initialize(&b); ...; end # Create new parser. def parse(args = ARGV); ...; end # Consume command-line args. def opt(...); ...; end # Declare supported option. def die(...); ...; end # Validation handler. end Then I have my own Parsers module which holds some metadata about parsers that I want to track. module Parsers ParserMap = {} def self.make_parser(kind, desc, &b) b ||= lambda {} module_eval { ParserMap[kind] = {:desc => "", :validation => lambda {} } ParserMap[kind][:desc] = desc # Create new parser identified by `<Kind>Parser`. Making a Parser is very # expensive, so we defer its creation until it's actually needed later # by wrapping it in a lambda and calling it when we actually need it. const_set(name_for_parser(kind), lambda { Parser.new(&b) }) } end # ... end Now when you want to add a new parser, you can call make_parser like so: make_parser :db, "login to database" do # Options that this parser knows how to parse. opt :verbose, "be verbose with output messages" opt :uid, "user id" opt :pwd, "password" end Cool. But there's a problem. We want to optionally associate validation with each parser, so that we can write something like: validation = lambda { |parser, opts| parser.die unless opts[:uid] && opts[:pwd] # Must provide login. } The interface contract with Parser says that we can't do any validation until after Parser#parse has been called. So, we want to do the following: Associate an optional block with every Parser we make with make_parser. We also want to be able to run this block, ideally as a new method called Parser#validate. But any on-demand method is equally suitable. How do we do that?

  • Rails and Python hosting problem

    - by maxxtack
    I am trying to host some files/rails app in the port 8080 for external access. For python I am using the SimpleHTTPServer module, and for rails, webrick. However, both of them does not work very well. I don't get the response back, and, sometimes, if I get it, it's VERY slow. Nevertheless, apache works very well on the port 8080 (i am not running them at the same time). What is going on?

  • Is a string formatter that pulls variables from its calling scope bad practice?

    - by Eric
    I have some code that does an awful lot of string formatting, Often, I end up with code along the lines of: "...".format(x=x, y=y, z=z, foo=foo, ...) Where I'm trying to interpolate a large number of variables into a large string. Is there a good reason not to write a function like this that uses the inspect module to find variables to interpolate? import inspect def interpolate(s): return s.format(**inspect.currentframe().f_back.f_locals) def generateTheString(x): y = foo(x) z = x + y # more calculations go here return interpolate("{x}, {y}, {z}")

  • Renaming table in rails

    - by Tommy
    I want to rename a table... (any table.) I tried this line of code: ActiveRecord::ConnectionAdapters::SchemaStatements.rename_table(old_name, new_name) Here's the weird thing. I know I got it working the first time, but now I get this error: undefined method `rename_table' for ActiveRecord::ConnectionAdapters::SchemaStatements:Module Was there something I need to set? Or am I going blind here.. Thanks!

  • Doubt in Conditional inclusion

    - by Philando Gullible
    This is actually extracted from my module (Pre-processor in C) The conditional expression could contain any C operator except for the assignment operators,increment, and decrement operators. I am not sure if I am getting this statement or not since I tried using this and it worked.Also for other manipulation a probable work around would be to simply declare macro or function inside the conditional expression,something like this to be precise. Also I don't understand what is the rationale behind this rule. Could somebody explain? Thanks

  • Forcing driver to device match

    - by shodanex
    I have a piece of usb hardware, for which I know the driver. However, the vendor id and product id do not match the VID, PID pair registered in the driver. Is there a way in linux to force a driver to be associated with a known device, that do not involve kernel module recompilation to add a PID / VID pair ?

  • What is your most useful C/C++ snippet?

    - by maddizzyro
    Hello all, It seems that every project has an "util" module with various code snippets used throughout other files and which don't fit any particular pattern. I want to improve my "util" library, so please post here the most useful class / function / macro that you use in all your C/C++ projects. Please keep the entries small (under 100 lines) and give only one example per post. Thank you.

  • How can I define multiple types with the same name and different type parameters using Reflection Em

    - by wawa
    How can I generate types like these using the System.Reflection.Emit libraries: public class Test<T> {} public class Test<T1, T2> {} When I call ModuleBuilder.DefineType(string) with the second type declaration, I get an exception because there is already another type in the module with the same name (I've already defined the type parameter on the first type). Any ideas?

    - by nardbard
    Is it possible to use P4Python (the perforce python api) with IronPython? I'd like to use the python api because it seems much faster than using p4.net implementionat of a Perforce API but when I try to import p4 into IronPython I receive the following error.

  • retreive the url of the page an image sits on

    - by Ayyash
    I'm trying to log URLs that access broken images, using an HTTP module to catch those images when accessed. How do you retrieve the URL where that image sits on? is there a way to do it the other way round too? That is, loop through images served in a URL and decide which ones are broken. This is all in ASP.NET with C#.
