cannot findobj() when running as an EXE application

Hi Guys,

I have this weird issue where when im running my application from the Matlab env. everything is working well. when i later on compile it into an EXE and run it, it doesn't work. debugging showed me that the problem is when calling findobj();. when running in Matlab it returns the handle to the object im looking for and when running as an EXE it doesnt. For reference, see attached 2 images. one taken from within matlab and the second from the cmd prompt when EXE was running.

Console output running code from Matlab:

console output running compiled code from windows:

Code used:

    % resetAllCheckBoxes(h);
     checkBoxHandle =  findobj('Tag',['param_',num2str(checkBoxNum)]);
     disp('CHECK BOX HANDLE:')
     checkBoxHandle
     input('Press entere to continue');
     set(checkBoxHandle,'Value',1);
  end

Any idea whats going on here?

Add this code

str = ['param_',num2str(checkBoxNum)]
fprintf('checkBoxNum = %f\nLooking for tag = %s', checkBoxNum, str);

Any difference in what you see between the compiled and development environment?

Hi, THanks. I changed the code to the below and now it is working. still cant say why it didnt work before...

resetAllCheckBoxes(h);

    set(h.(strcat('param_',num2str(checkBoxNum))),'Value',1);

You might want to investigate what ishandle() returns:

itsAValidHandle = ishandle(checkBoxHandle)
