Tring to figure out how to use the GvPort->SetData command without crashing C4D. I want to pass a BaseLink and or our own custom datatypes.

Sorry, I am still investigating this and the corresponding GetData() issue. Will report back as soon as I hear anything.

First, I guess this cannot be repeated too often:

In other words, don't rely on the current GV or TP system to be either predictable, stable or consistent. I know I've told you this privately, but it deserved to be said in public as well.
That being said, I found some more information about allocating Dynamic Data within Xpresso. From studying the functions in c4d_graphview.h some things can be learned. To use GetData() you must first call GvAllocDynamicData(), then you can use data.data as d. (I couldn't get this to work though.) For GeData-Gv conversion, see the GvSetDataInContainer() implementation.

OK, where is the GvSetDataInContainer() implementation?
Thanks, darf

In other news: find-in-files useful for finding stuff in files... ;-)
//c4d_graphview.h
inline Bool GvSetDataInContainer(const void* const data, GvValueID value_id, BaseContainer &bc, LONG container_id, LONG cpu_id = 0)
{
CUSTOMDATATYPEPLUGIN* pl = FindCustomDataTypePlugin(value_id); if (!pl) return FALSE;
GeData ge_data; CallCustomDataType(pl,ConvertGvToGeData)(data,cpu_id,ge_data);
bc.SetData(container_id,ge_data);
return TRUE;
}
I.e. it calls a function pointer function in the CUSTOMDATATYPEPLUGIN. I don't really know what value_id to use here for BaseLink. Perhaps something interesting can be found if browsig the Registry for e.g. C4DPL_CUSTOMDATATYPE items. (Haven't tried myself, don't have the time at the moment.)
