this is an internal function used to build dwgdirect com interface - dwgdirectx. what do you need it for?

i am creating an dwg view activex control, used iunknownptr to pass oddbdatabaseptr, so i could use the common oddbdatabase, beteewn two dwgview view controls, how can i solve this problem? can i call function: odoxgetolelinkmanager()? thanks a lot

if you are creating activex not dependent on odax or dwgdirectx, you should maintain the mapping between database and it's com wrapper yourself. if you are using ddx, then there is an interface called iacadbasedatabase to retreive/set oddbdatabase to/from a ddx wrapper.
but the thing you are trying to implement is impossible for other reasons - one database cannot be displayed simultaneously in different threads (using worlddraw/viewportdraw), ( e.g. because entities may contain caches, built while first regen)

thanks to vladimir!
i have an other question: why odgslayouthelperptr->update() funcion need lots of memory used in an activex control? can i free the momory? for example it needs 30m memory if i use my dwgview activexcontrol, but it only need 12m if i use a mfc application , if i donot call odgslayouthelperptr->update(), there needs the same momory.
maybe conveyor is set up differently?
or gsmodel enabled/disabled?
