MATLAB: Do I get error “The specified file could not be found” for the deployed application that uses “actxserver”

activexfilefoundMATLAB Compilernotpowerpoint

I am currently deploying an application I created in MATLAB.

The problem which occurs here is while generating an activeX presentation with the following lines :

ppt = actxserver('PowerPoint.Application');
ppt.Visible = 1;
pTemplate = 'Template.pptx';
Presentation = ppt.Presentation.Open(pTemplate)

When the app is deployed it returns me an error :

Error using Interface.91493462_5A91_11CF_8700_00AA0060263B/Open
Invoke Error, Dispatch Exception: Le fichier spécifié est introuvable.
(The specified file could not be found)

I do not see this error when running the application from within MATLAB. Furthermore, this error continues even if the file is included as a dependency when I compile it.

How can I make sure my compiled application finds this file?

This application is able to run from within MATLAB because 'Template.pptx' was on the file path.

In order to use this file in a deployed application, the full path must be specified in the argument to "ppt.Presentation.Open".

MATLAB: How to use MATLAB Compiler to compile an application that uses a report and stylesheet generated by MATLAB Report Generator

In order to include the report and stylesheet in your application, use MCC's -a flag as follows:

mcc -m myfile.m -a myreport.rpt -a mystylesheet.rgs

This will add the RPT and RGS files to the CTF archive which is created by MATLAB Compiler and these files when then be accessible by the compiled application.

Note that if you modify the call to REPORT to use the absolute path to the report file, then the report file and stylesheet must be located in that same location on the deployment machine and you would not use the -a flag.

MATLAB: How to add sections to PowerPoint with MATLAB Report Generator

Hi Ruixin,

Currently, the MATLAB Report Generator's PPT API does not support creating sections programmatically.

The team plans to add this functionality in the future releases.

Alternatively, as a workaround, you can add sections in your template presentation with maybe a single slide in each section, for e.g., a Section Header slide. Then generate your new presentation using this template presentation and add the new slides using the index number, which represents the position of this new slide in the generated presentation. See https://www.mathworks.com/help/rptgen/ug/mlreportgen.ppt.presentation.add.html

For example, create a template presentation, named input.pptx, with 2 sections where each section consists of a single section header slide, as shown below:

Now create your output presentation using this input presentation as shown below:

ppt = mlreportgen.ppt.Presentation("output.pptx", "input.pptx");
open(ppt);
% Add slide to Section1.
% Specify the index as 2 as this needs to be inserted after the 
% Section 1 header slide which is present at index 1.
sect1Slide = add(ppt,'Title and Content',2);
% Add slide to Section2.
% Specify the index as 4 as this needs to be inserted after the 
% Section 2 header slide which is now present at at index 3.
sect2Slide = add(ppt,'Title and Content',4);
close(ppt);
rptview(ppt);

The generated output presentation looks like:

Hope this helps!

Thanks,

Rahul
