Re: [SyncEvolution] sqlite backend enhancement

Hi Lukas Thanks for the response. I followed your tips but It didn't work here is my code : *TSyError res = this->ui.GetValueByID(this,** * * aItemKey,** ** valueId, ** ** ** **idx,** ** ** **sysync::VALTYPE_BUF,** ** ** **NULL,** ** ** **0,** ** ** **&valsize** ** ** **);** ** if(!res && valsize){** ** ** **data = SharedBuffer(new char[valsize*1024*1024 + 1], valsize);** ** ** **data[valsize] = 0;** ** ** **res = this->ui.GetValueByID(this,* * ** ** ** * *aItemKey,** ** ** ** * *valueId,** ** ** ** * *idx,* * sysync::VALTYPE_BUF, data.get(), valsize + 1, &valsize ); }* I ve got size = 2759 but i always extract 4 bytes. Can you help me please?
