Regarding VPT.SE's point, I have restarted PC and open with my VB application. so there isn't any program open. Also as you suggested I have added 10-20 sec puase between part.open and part.execute. so as per my best, I have tried all precautions mentioned in this complete thread and many more. But still problem remains same run program in offline only.
OK, I will add PC-DMIS 2012 MR1 Object Library. in project and will give try once again and will post my comments on that.
