yuki_wu	Posted - 08/23/2018 : 03:23:06 AM Hi couturier, There are a few of functions may help: https://www.originlab.com/doc/OriginC/ref/OriginObject-GetIncomingOperation https://www.originlab.com/doc/OriginC/ref/OriginObject-FindIncomingOperations https://www.originlab.com/doc/OriginC/ref/DataObject-IsFormulaAutoUpdate I also thought of a tricky method: void IsLocked() { Worksheet wks = Project.ActiveLayer(); Column col(wks, 1); if(!col) return; vector& vec = col.GetDataObject(); double dCur = vec[0]; double dNew = -999; try{ vec[0] = dNew; } catch(int nErr) { out_str("Locked"); return; } vec[0] = dCur; return; } Hope it can be some help. Regards, Yuki OriginLab
