Here I go again. I solved the problem I had for a moment, using absolute Path putting the .txt file i wanted to read in a folder out of the proyect. As you said to me @jwatte, now I’m trying to add the .txt within the proyect in order to package it. Then I have the same problen when using relative path. I have seen that the current directory of a visual studio proyect is where .vcproj project file resides. I have tried to put the .txt there but it doesn’t work. I have also tried to write a file in order to create it and see where it is but for some reason it is not created anywhere. Any help please?
