- The 'dllPath' and 'headerFile' should be correctly defined in the code in order to use them correctly.
- This assumes that 'app.statusText' is a valid UI property. If 'app.statusText' does not exist or is not correct type of UI control this line will throw an error.
- Lastly try changing the line 'app.statusText.Text = errorMessage;' to app.statusText.Text = ex.message' and then try to run the code.

Error loading DLL: Property assignment is not allowed when the object is empty. Use subscripted assignment to create an array element.

Error in App_Sushant_2/startupFcn (line 124)
app.statusText.Text = errorMessage;
The code refreed to in the error message shows assigning a public property as app.dllHandle and has it code as follows:
- methods (Access = public)
% Construct app
function app = App_Sushant_2
app.dllHandle = [];
- try
% Load the DLL and store the handle in dllHandle property
app.dllHandle = loadlibrary(dllPath, headerFile); %'alias', 'Neurostimulator_HID_DLL_2'
app.statusText.Text = 'DLL loaded successfully';
catch ex
% Display error message if DLL loading fails
errorMessage = sprintf('Error loading DLL: %s', ex.message);
disp(errorMessage);
app.statusText.Text = errorMessage;
return;
end
