  1. Hi All, I m trying to build a software, and data management has become too complex. In short, it is acquiring data from three channels and doing some calculations and then showing and reporting that data for the user to make a fitting decision. The user then, can save the file and import the saved worked-up file later to view or manipulate. The data consist of three interdependent data set, and so far, I have collected the dat as an array of clusters (size 3) for three sets and kept user input data in the same manner. I am also using a simple "producer/consumer" design. However, I think that may have been a mistake, and I might be able to do a better job using either actor or QMH design, especially since I need to think about adding the acquisition part (which is not yet developed). The thing is that I have not used oop before at all and am not quite sure if this is the correct approach and how should I bundle my data. Considering that the data (not all but some) need to be accessed by other classes if I goo with oop. For example, should I keep the data as separate class data and use methods for override or keep it as an array in the parent class and use static methods and only use child classes for graphing. These are the type of questions I am struggling with. Also, can anyone help me decide between DQMH, Actor or just standard Producer/Consumer patterns, please? I am completely lost. Thank you in advence. This is how the front pannel looks like: And this is the data set for the system (which I am keeping as an array) there will me more data added to this as the capabiliy grows.
  2. I recently ran into this issue and wanted to know what the community has to say about it. I have a main program that is a QMH that can launch a single actor (picked by the main program and loaded through PPL) to perform a task. I want to have that actor update a CVT for the main program to monitor. I set up the CVT in the main program and had the actor write to CVT. When that call happens I get an error that it can't find that tag in the CVT. I have a CVT viewer that shows that exact tag, though. For testing, I setup the CVT in the actor with the exact same tag list and it finds it just fine. This leads me to believe that the QMH main program lives in a different memory space from the actor. (Maybe things loaded through a PPL live in different memory?) The current work-around is to send the value back to the main program. I don't really like doing that but it is what it is. My next option will be to convert the main program to an actor and see if the child actor can see the CVT setup by the main actor. Any thoughts on this? Maybe I'm doing something wrong? Edit: Tested a QMH with an actor called directly, instead of through a PPL and the actor can see the CVT without error. Next up, trying a packed actor called directly instead of loaded dynamically. Edit 2: Created a trivial PPL actor and called it directly from the main program and it could not see the CVT. Is there a good workaround for this?
  3. Hi I have a very strange Actor Launch problem. I start an Actor to do some calculations for every attached DUT. And that has been working great, 1,2,3 Actors(DUTs) no problem. But now I’m starting to get problem when I have around 5 or more Actors that I start of the same type. The screenshot below shows my problem. The queue used to get the Actor’s Enqueuer back after the Asynchronous start of the Actor, didn’t receive anything. I debugged the code, and could see that the Queue-Reference was the same for the Enqueuer and the Dequeuer. Also no errors were found on the Enqueuer Error in. Has anybody seen something similar? The code only fails if there are too many started actors at the same time! Cheers, Mike
