Get Mac Address in MFC

GetMacAddress in MFC

Get by using GetAdaptersInfo function
//

..
Get by using ip address
//If localhost -> GetMacAddress(_T("*"));
//if have ip -> GetMacAddress(_T("192.168.1.1"));//

..

CString to string

..

string CstringToString(CString str)
{
    CT2CA pszConvertedAnsiString(str);
    std::string s(pszConvertedAnsiString);

    return s;
}

findContours, drawContours example code

The code is various example code for drawing contours.


...

namedWindow("show1", 0);
 namedWindow("threshold", 0);
 namedWindow("contours", 0);

 Mat img;
 img = imread("pattern.jpg");

 cvtColor(img, img, CV_RGB2GRAY);
 
 imshow("show1", img);


 threshold(img, img, 128, 255, CV_THRESH_BINARY);
 imshow("threshold", img);


 Mat dst = Mat::zeros(img.rows, img.cols, CV_8UC3);
 
 vector< vector< Point> > contours;
 vector< Vec4i> hierarchy;

 findContours(img.clone(), contours, hierarchy,
  RETR_CCOMP, CHAIN_APPROX_SIMPLE);

 
 //ex 1)
 drawContours(dst, contours, -1, CV_RGB(255,0,0), 1, 8, hierarchy);

 
 // iterate through all the top-level contours,
 // draw each connected component with its own random color
 //ex 2)
 int idx = 0;
 for (; idx >= 0; idx = hierarchy[idx][0])
 {
  Scalar color(rand() & 255, rand() & 255, rand() & 255);
  //drawContours(dst, contours, idx, color, FILLED, 8, hierarchy);
  drawContours(dst, contours, idx, color, 1, 8, hierarchy);
 }
 


 //ex3
 for (int i = 0; i < contours.size(); ++i)
 {
  
  for (int j = 0; j < contours[i].size() - 1; ++j)
  {
   line(dst, contours[i][j], contours[i][j + 1], CV_RGB(255, 0, 0), 1);
  }

File exist check code

bool fileExists(const char* path)

  FILE* file;
  bool exists;

  file = fileOpen(path, "r");

  return exists;
}

FILE* fileOpen(const char* path, const char* mode)

  char path_[PATH_MAX];

  assert(path);

  FILE* fp;
  fopen_s(&fp, path_, mode);
  return fp;

explanation of _CRT_SECURE_NO_WARNINGS, VO_MSE_FUNC_THROUGH_POINTERS option in Visual Studio

I was then able to build your project proceeding as follows:
-in the Preprocessor Definitions, you did not add both compiler options _CRT_SECURE_NO_WARNINGS and VO_MSE_FUNC_THROUGH_POINTERS
_CRT_SECURE_NO_WARNINGS is necessary to use the strcpy function
VO_MSE_FUNC_THROUGH_POINTERS is needed to get the pointers to the exported functions of the libraries
-Also, as your code is c++, you need to add extern "C" to "voEngine engine = NULL;" and "#include "
// global engine (for the sake of readability)
extern "C" voEngine engine = NULL;

// common utility functions
extern "C" {
#include
}
