I am using AFSDK 4.0 (18.104.22.16843) in VB .Net 2012. Attempting to delete values from PI using the AFUpdateOption.Remove for PIPoint.UpdateValues. I am retrieving values, adding them to a listview, and then creating value objects by iterating through the list and attempting the deletion. The events do not get deleted and the return status is nothing, implying no errors. I have found a very similar call
Case # 552245
Their solution was to delete using the orginal value objects. They had been reading from a vb control, then building value objects\value list. This is also what I am doing. However, I do not want to use the original list as I am letting users select the values they want to delete through the listview. Note, from the original AFValues I am storing UTCseconds and using to create the dates for the AFValues passed to be deleted. I was not doing that originally but thought the problem was a date precision one.
