  • C++ for Ruby scripters

    - by Aaron Cohen
    I am a fairly capable Ruby scripter/programmer, but have been feeling pressure to branch out into C++. I haven't been able to find any sites along the lines of "C++ for Ruby Programmers". This site exists for Python (which is quite similar, I know). Does anyone know of a guide that can help me translate my Ruby 'thoughts' into C++?

  • webapp and django framework

    - by Joel
    As far as I understand, the "Getting Started" guide of GAE with Python uses the webapp framework. However, it seems like it uses Django to render templates. Does that mean that I can use the Django template engine without using its application framework?

  • Numeric representation of a color

    - by George Johnston
    What would be the best format to numerically represent a color in .NET so that I wouldn't have to use the Color object? Right now I am saving the color as a the HTML representation, but in order to use it I have to parse it out. I am dealing with a 800x600 canvas that stores a color value for each pixel and I need to be able to render the color out as quick as possible without bloating my application out to storing 500k+ color objects.

  • iPhone: no way to draw on screen outside drawRect?

    - by Seva Alekseyev
    Is there a way to draw on the iPhone screen (on a UIView in a UIWindow) outside of that view's drawRect() method? If so, how do I obtain the graphics context? The graphics guide mentions class NSGraphicsContext, but the relevant chapter seems like a blind copy/paste from Mac OS X docs, and there's no such class in iPhone SDK.

  • Using a dropdown on a static webpage as a DataSource in C#.net

    - by Matt
    I know this is a terrible way of doing things, but it's for an internal app where security is no issue. Basically, an old group created a php page with a drop down and this drop down is populated with entries from a DB. The DB owner is currently absent and for the sake of time, I would just need something that turns the entries in that drop down, always at the same url with the same ID every load into a List. Is there a quick, painless way to do this in .NET?

  • Instant win contest script

    Has anyone seen a good "quick" solution to duct tape together an instant win contest? I need to find a solution where a winner a day gets randomly selected after signing up for email.

  • How to parse the AndroidManifest.xml file inside an .apk package

    - by jnorris
    This file appears to be in a binary XML format. What is this format and how can it be parsed programmatically (as opposed to using the aapt dump tool in the SDK)? This binary format is not discussed in the in the documentation here: http://developer.android.com/guide/topics/manifest/manifest-intro.html Note: I want to access this information from outside the Android environment, preferably from Java.

  • Is it possible to capture audio output and apply effects to it?

    - by Ciaran
    Using .NET and DirectSound I want to be able to take all output sound that is coming from my audio device and apply effects to it. I've had a quick look at the docs on MSDN and there doesn't seem to be any explanation as to how to do something like this. I've read elsewhere that you'd be better off writing a driver to sit in front of your real audio driver and have that do whatever you want with the sound. Any ideas anyone to push me in the right direction?
