Hey all, I'm attempting to bind a function, then store it in a map. Later I want to call that function with parameters that I don't yet have when I bind it. So this is the code `boost::bind(&State::setBufferSourcePlaying, &::top->dsp->getState(), 0, 1 )` Currently I'm not binding any "dynamic" data, ie …

Hey All, I've been stumbling into the same (annoying little) problem a couple of times, and I'd like to find out how to fix it properly. Pseudo code [code=c++] // file A.hpp #include "classB.hpp" class A { A() }; // file A.cpp A::A() { } [/code] [code=c++] // file B.hpp …

Hey all, (Skip down till "Question:" if you're in a rush) Context: I'm coding on an audio application which involves storing buffers of audio. I'm currently using a [ICODE]std::vector<float>[/ICODE], as a member of an [ICODE]AudioBuffer[/ICODE] class. These [ICODE]AudioBuffer[/ICODE] instances are held in another class [ICODE]ResourceHolder[/ICODE]. In the "process" callback (where …

Hey all, I've a couple of large enough vectors in my code, talking about 88200+ floats per vector. I wanna copy the contents of one into the other. I've read around, some say [code=c++]vector.swap ( otherVector );[/code] is fastest? Currently I'm using the following: [code=c++]for(int i =0; i < vector.size(); …

Hey guys, I written a base class (AudioTrackElement), and derived a class from there (Looper) and another (VolumePan). The looper class implements functionality, while the AudioTrackElement is there just so I can hold many Loopers and VolumePan objects in the same vector. The problem: I can create a [icode]std::vector<AudioTrackElement>[/icode] no …

Hey all, Slight continuation on[URL="http://www.daniweb.com/forums/post1092017.html"] this thread.. [/URL] Not essential though. Hence the new thread.
