Use of OPENCV library in visual C++ win32 console application

Hello All,

After installing,configuring OPENCV in Microsoft visual studio,I created a project ,used opencv functions and simply compiled,which worked fine but giving error while running it.i.e. missing some opencv dll file.Please reinstall your application.

I have reinstalled the app,but of no use.
Earlier while configuration,I put the dir at D drive,Changed it to C drive but same dll missing error.
Below is my three lines of code.

#include "stdafx.h"
#include <string>
#include <stdio.h>
#include "opencv2/core/core.hpp"
#include "opencv2/imgproc/imgproc.hpp"
#include "opencv2/highgui/highgui.hpp"
using namespace cv;

int _tmain(int argc, _TCHAR* argv[])
{
      std::string Imgpath="C:\testImage";
      Mat img = imread(Imgpath, CV_LOAD_IMAGE_UNCHANGED);
      /*Size new_size = img.size();
      resize(img, img, new_size);
      namedWindow("Step 1", CV_WINDOW_AUTOSIZE);
      imshow("Step 1", img);*/

      return 0;
}

Please help.
