Hello,

I'm writting here because I have a proble that I cannot solve by myself...

I developped matlab functions that I wanted to transfer to VB.Net through a .dll. I successfully compiled the .dll with Matlab compiler and imported it to VB.NET.

But now I'm trying to use it and i definitly don't understand why it doesn't wor. That is what I writted on VB.net

Imports StatFeaturesExtractor
sub*****
        Dim Extractor As StatFeaturesExtractor.Extractor
        Dim MatlabTypePath As MathWorks.MATLAB.NET.Arrays.MWArray
        MatlabTypePath = New MathWorks.MATLAB.NET.Arrays.MWCharArray(path)  '==> this line already bug...
          Dim Result As MathWorks.MATLAB.NET.Arrays.MWArray
          Result = Extractor.StatFeatureExtractor(MatlabTypePath)
  end sub

for your comprehention, StatFeatureExtractor is a simlpe to use (theorically) as the only argument is a string (a path) and the result consist of a 8x1 array of double

thank for your help

What is your variable path? What does it contain? Which data type does it have? What error do you get? What do you mean with "this line already bug"?

Path is a string it contains a path to my hard drive the error I have is " Une exception a été levée par l'initialiseur de type pour 'MathWorks.MATLAB.NET.Arrays.MWArray'. "
