Create Visual Studio Project with API from matlab

Hi everyone, I have to create a visual studio project (programmatically) from Matlab, using the API present in this site

https://docs.microsoft.com/en-us/dotnet/api/envdte.projects?view=visualstudiosdk-2017. In the last folder of the path below, there are files .h and .c. Anyone has encountered a problem like this? I'm using Visual Studio 2017 and Matlab 2019b.

I show what are the APIs that I'm using that don't work:

openedVS = actxGetRunningServer('VisualStudio.DTE.15.0');

sol=openedVS.DTE.Solution;

sol.Create('C:\Users\matte\Desktop\VisualStudio','MyNewSolution');

sol.SaveAs('C:\Users\matte\Desktop\VisualStudio\MyNewSolution.sln');

proj=sol.AddFromTemplate('C:\Users\matte\Desktop\VisualStudio\ConsoleApplication1\ConsoleApplication1\ConsoleApplication1.vcxproj','C:\Users\matte\Desktop\VisualStudio','My New Project',true);

proj.ProjectItems.AddFromDirectory('C:\Users\matte\Desktop\Tesi\file generazione\file generati\');

On the last row of code I obtain the followng error:

Error using Interface.8E2F1269_185E_43C7_8899_950AD2769CCF/AddFromDirectory

Invoke Error, Dispatch Exception: Non implementato

Error in Creazione_Progetto (line 7)

proj.ProjectItems.AddFromDirectory('C:\Users\matte\Desktop\Tesi\file generazione\file generati\');

Hi @Matteo Boccino,

I am able to reproduce the error you are facing. This is actually expected behavior because ProjectItems.AddFromDirectory() is not implemented for all project types (especially VC++ projects), or not exposed through the DTE automation layer.

As a workaround, instead of using AddFromDirectory(), you’ll need to add the .c and .h files individually using AddFromFile() or AddFromFileCopy() as shown below:

folderPath = 'C:\Users\matte\Desktop\Tesi\file generazione\file generati\';
files = dir(fullfile(folderPath, '*.c'));
files = [files; dir(fullfile(folderPath, '*.h'))];

for k = 1:length(files)
    fullPath = fullfile(folderPath, files(k).name);
    proj.ProjectItems.AddFromFile(fullPath); % Or AddFromFileCopy if you want a copy
end

Also note that if you're trying to add these to a specific folder inside the project, like proj.ProjectItems.Item("Source Files").ProjectItems.AddFromFile(...), you’ll need to navigate through the project tree.

I hope this helps resolve the issue!
