Issue While Making an App in MATLAB 2019a

[ae3007]

Hi,

I have a script that runs well. I try copying and pasting it into the app. This does not work. It seems if I have run it as a script before I open the app, the app works. If I open MATLAB and run the app, this does not work. The error I get is below. I think it has to do with loading libraries. Any thoughts?

Operation failed: An error occurred while executing the driver disconnect code.
Dot indexing is not supported for variables of this type.
If this error is not an instrument error, use MIDEDIT to inspect the driver.

Error in icdevice (line 311)
delete(obj);

Thanks,

Adam

The error seems to come from this section of the initialization part of the .mdd:

init(obj)

if(ispc)
[ps2000NotFound, ps2000Warnings] = loadlibrary('ps2000.dll', @ps2000MFile);

elseif(ismac)

[ps2000NotFound, ps2000Warnings] = loadlibrary('libps2000.dylib', @ps2000MFile, 'alias', 'ps2000');

elseif(isunix)

[ps2000NotFound, ps2000Warnings] = loadlibrary('libps2000.so', @ps2000MFile, 'alias', 'ps2000');

else

% Do nothing

end

end

% Only load library once
if(libisloaded('ps2000Wrap'))

% Do nothing

else

if(ispc)

[ps2000NotFound, ps2000Warnings] = loadlibrary('ps2000Wrap.dll', @ps2000WrapMFile);

elseif(ismac)

[ps2000NotFound, ps2000Warnings] = loadlibrary('libps2000wrap.dylib', @ps2000WrapMFile, 'alias', 'ps2000Wrap');

elseif(isunix)

[ps2000NotFound, ps2000Warnings] = loadlibrary('libps2000Wrap.so', @ps2000WrapMFile, 'alias', 'ps2000Wrap');

else

% Do nothing

end

end

Hi

Are you able to post your app code so that I can have a look what is going on and try to reproduce the issue?
