Code snippets for uber-n00bs

[drew]

Guessing I'm not alone here... I'd sure appreciate the odd code snippet here & there.

Things like:
cycling through all project media on all tracks and reading the takes & items, so I can make lists of names/durations of items etc
moving selected items
moving cursor backwards & forwards according to project tempo.

Thanks!

I haven't checked if this actually works... But something along these lines would get you the project's items' lengths and active take names...

void DoDumpItemDurationsandActiveTakeNames()
{
	
	MediaTrack* TheTrack;
	MediaItem* CurItem;
	MediaItem_Take* CurTake;
	int numItems=0;
	char TempString[500];
	for (int i=0;i<GetNumTracks();i++)
	{
		TheTrack= CSurf_TrackFromID(i+1,FALSE); // we get the pointer/handle to track using the CSurf API, i+1 comes from 0 being the master track, we don't expect items there
		numItems=GetTrackNumMediaItems(TheTrack);
		for (int j=0;j<numItems;j++)
		{
			CurItem = GetTrackMediaItem(TheTrack,j);
			if (GetMediaItemNumTakes(CurItem)>0) // empty items don't have any takes, so following code could maybe  crash without checking there are takes
			{
					CurTake=GetMediaItemTake(CurItem,-1); // -1 gets the active take
					double ItemLength=*(double*)GetSetMediaItemInfo(CurItem,"D_LENGTH",NULL);
					char *TakeName=(char*)GetSetMediaItemTakeInfo(CurTake,"P_NAME",NULL);
					// format some kind of text output 
					sprintf(TempString,"Track %d item number %d active take has name %s and length %f",i+1,j+1,TakeName,ItemLength);
					// we are super lazy and just output to the debug viewer
					OutputDebugString(TempString);
			}
				
		} 


	}
}

Finally tried this - and success!!! ThanX Xenakios!
