And when you ask them what steps they took to get the error it is always "I don't know I was just pressing buttons".

Out of curiousity I looked to see if Harris Technology did the rest of the code the same way I would do, and they did. (I don't feel so weird now )

Version 2.8 has just been uploaded.

I have made the code for Undo a little more efficient and it now has 5 steps (for Undo and Redo), it could easily be more, I just don't want to take up too much memory and 5 steps seems sufficient.

Let me know if more would be helpful.

Thanks SS,

I am now going to stop working on the GUI for a little bit as I think I can make it so that you can also have multiple side branches to your enclosure. It would be great to include this functionality but it's potentially quite hard to program.

Anyway, I'll give it a go.

Looks good!


I think it needs a catchier name than TransmissionLine.application

Wow... finding this thread just made my day.

I've been waiting for a program like this for a very long time, and what you have here is exceptional! I modelled a full TL in less than 10 minutes from program open to satisfied result. Everything is very well laid out, input is logical, and the graphs do appear to be accurate. Driver parameter entry was simple, and everything seems to work as expected.

Kudos to schmeet for a job very well done, and for sharing!

In terms of debugging, I have the following comments:

1. On startup the "Make a directory" box appears behind the splash screen and makes it look like the program has frozen. It wasn't until I clicked on the program's tab on the windows bar that the GUI for directory selection appeared.

2. After entering a driver's parameters in the driver window, I clicked save and everything worked perfectly, but clicking in the white "Driver Library" box caused a recoverable crash.

3. Lvc is in Henries, which caught me out the first time through. After looking more closely, I notice that all your units are consistent, but this one might be best left in mH since every datasheet I've ever seem gives Lvc in this format. I had initially put in 1.35H and all the graphs were nonsense, it wasn't until closer inspection that I found my error and re-entered as 0.00135H

4. I'm still wondering what "Enclosure Width" does since it didn't appear to change anything on the graphs. I'm guessing it's used to derive the IB response for baffle step? If so, it doesn't appear to do anything. Going from 0.1 to 10 doesn't change the graphs at all.

For reference, I'm running Win 7 64-bit.

Thanks again for this wonderful contribution, and honestly, if it just stayed the way it is now, I'd be more than happy The above is simply nitpicking.

Cheers,
Owen
