Hello. I have an app that controls several external devices using the comms port and serial communication. I use the same app on about 5 different computers and the comms ports are always different.
For each of my external devices, I use a drop down to select the comms ports (i.e. Com2) but set the default value. But when I run the app on a different instrument, I need to go to all the drop downs and select the relevant comms port.
(My app is compiled by the way and the target computers have the runtime compile installed)
My questions are:
1: Can I get the default value (of the dropsown box) to change and be permanent after I first change it.
2: If not, can I use a file to read in at startup, so this inititalisation text file can be changed for each computer (..how do you read a file from the actual deployed directory)
Thanks
Jason

You have to use "load" / "save" functions to store and reload your settings.
The app does not support permanent changes of the compiled code.

Actually, mfilename doesn't work for deployed apps (i.e. an EXE created)
It returns this, but my actual exe is in C:\Matlab\EXE\
'C:\Users\Scan\AppData\Local\Temp\Scan\mcrCache9.9\....

Good point. I'm not sure whether I'm allowed to put external links here but you can search the internet for this.
I found one idea which sends the 'path' command to the system and just checks the latest entry - which should be the app execution path. Sorry for not being more pecise.
