C# Problem with calling many ItemNames for AdxRtHistory

Having problems retrieving data using the AdxRtHistory class in C#

AdxRtHistory work well for for retrieving past data for a small group of RICs however for large numbers of RICs AdxRtHistory just returns the first 1MB worth of data. The program is currently retrieving the data in one massive batch, I tried doing multiple batches (on the same program) but with no success. Was wondering if anyone has a solution to this problem

Thanks in advance

I suggest you use the .NET Data API which has more functionality that the AdxRtHistory. The tutorials can be found here.

@yuri.gt a couple of questions:

is there an error or the request just times out?

could you specify the exact number of RICs, e.g. 100 for large requests and 10 for a small group.

There is no error or time out. After about 300-400 RICs or so the program will pause, get the data for those RICs and then fail to get the RIC data for the remaining RICs after that pause. The program would resume and execute without retrieving the data for the last few RICs

I'm also quite sure that it's not a problem with the RIC format, I changed the order of the input of RICs and the program continued to have that brief pause at around 300-400 RICs.

I'm currently using the ItemNames attribute in AdxRtHistory which is a string parameter, I don't think this is the right attribute for calling many RICs since a List would be more suited for the purpose however I'm not sure of the attribute name or if one even exists?
