How to convert this .net code to arx?

[D_D_K]

Hi,

I'm trying to convert this code to arx, however at the end I can't get the dimstyletablerecord (it always returns NULL),

I don't know what I missed? 

ID dimid;
DST* dst; //dimstyletable
...
DSTBR* dstr = new DSTBR; //dimstyletablerecord
dstr->setName(L"Test");
ErrorStatus e= dst->add(dimid,dstr);
dst->close();
DSTBR* dimtab = nullptr; 
acdbOpenObject(dimtab, dimid, fR); <---dimtab return NULL.
