I configurate the hardware, OPC server, and from VB Iconnected to the OPC server, add a new group, but can't add item and items, for example,VB program is: myopcgroup.opcitems.additem("D445.ST_1.test_opc",1) I just want add one item. But I monitor VB variable, found in group, there is nothing, no item in the group. In VB 6, no problem, everything is OK. but in visual stadio 2010, (VB10), it's problem. Thanks.
