@rwblinn, sorry I am using b4j 3.71 and I cannot run your version. Any way I will try and explain exactly what the problem is.
I have made slight changes in the app as the Mime was incorrect.
- Take the attached zip file as the new app version.
- Copy the MyDesktop.txt to a known directory and rename to MyDesktop.Desktop
- Set a breakpoint on line 358
- Click "Load File" and select the MyDesktop.Desktop file you have saved somewhere.
The app will now stop at line 358 "cbMime2_SelectedIndexChanged", Index=1 and Value=3gpp and in the UI the value 3gpp is visible - great.
- Step through the subroutine
- After "End Sub" the value in the UI is gone! This is what I don't understand, I have not done anything.
- Even worse, the sub then runs a second time??????
This has got to be something simple but it is driving me nuts.
My pi is currently not connected
Sorry, my original plan was to use this app on my RPi but the filechooser does not work, therefore it only works in windows.
