Create GUI App in c++ and c# with DLL Library Framework on Visual studio 2017 57
Shows how to create a #GUI windows form project with #dll library in c plus plus and c sharp on visual studio 2017
C++ code:
//MYForm.cpp is one file
#include "MyForm.h"
int main()
{
guicpp::MyForm form;
form.ShowDialog();
return 0;
}
//Source.cpp is one source file
#include ＜iostream＞ //for cout
#include ＜fstream＞ // for ofstream/ifstream
#include ＜string＞ //for ＜＜ and getline
#include＜list＞ //for lists
#include "Header.h"

{
std::ifstream input_file(in_file.c_str());
elements.clear();
std::string line;
for (int line_no = 1; std::getline(input_file, line); ++line_no)
{
elements.push_back(line);
}
input_file.close();
}
void Header::show_contents(std::ostream &out, const std::list＜std::string＞ &elements)
{

}
}

show_contents(output_file, elements);// using polymorphism
output_file.close();
}
