Hello crydev

If MovieInfo has operator< it is easy, just call Sort(myvector);

If not, you can do this:

struct MySortWay {
	bool operator () (const MovieInfo& a, MovieInfo& b) const { 
		return a.value < b.value; // Just an example. It dependes on MovieInfo contents
	}
};

Vector <MovieInfo> myvector;

Sort(myvector, MySortWay);

Thanks Koldo, this makes sense to me. I tried it using the operator < which I created inside MovieInfo:

bool operator < (const MovieInfo& pComp) const
{
	return pComp.cFullPath > cFullPath;
};

However, the two Sort methods do not have the same algorithm! I have tried to find out another way of fixing my problem but since I am using callbacks to fill up my ArrayCtrl one item by another from another thread I'm having trouble finding out how I could sort on the fly.

The ArrayCtrl.Sort() and Sort(myVector) both sort alphabetically, but not exactly the same. What should I do to abandon this problem? Is there a way maybe to sort on the fly so I can keep my callback system?
