Taking input parameter in C++ Win32 console application - visual-c++

Question

I generated C++ shared library in MATLAB and integrated it in Win32 console application in C++. I have to call this console application from PHP.It has 5 inputs which should be passed from php. When I run the application giving the input parameters it runs. The code which runs properly is as below:
#include "stdafx.h"
#include "shoes_sharedlibrary.h"
#include <iostream>
#include <string.h>
#include "mex.h"
using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{
/* Call the MCR and library initialization functions */
if( !mclInitializeApplication(NULL,0) )
{
exit(1);
}
if (!shoes_sharedlibraryInitialize())
{
exit(1);
}
mwArray img= "C:/Users/aadbi.a/Desktop/dressimages/T1k5aHXjNqXXc4MOI3_050416.jpg";
double wt1 = 0;
mwArray C(wt1);
double wt2=0;
mwArray F(wt2);
double wt3=0;
mwArray T(wt3);
double wt4=1;
mwArray S(wt4);
test_shoes(img,C,F,T,S);
shoes_sharedlibraryTerminate();
mclTerminateApplication();
return 0;
}
The C,F,T,S are value between 0 and 1. How can I pass the input arguments as it is in _TCHAR*?How can I convert the _TCHAR* into decimal or double and again converting that into mwArray to pass into test_shoes. The test_shoes only takes mwArray as input.
The test_shoes function definition is:
void MW_CALL_CONV test_shoes(const mwArray& img_path, const mwArray& Wcoarse_colors,
const mwArray& Wfine_colors, const mwArray& Wtexture, const
mwArray& Wshape)
{
mclcppMlfFeval(_mcr_inst, "test_shoes", 0, 0, 5, &img_path, &Wcoarse_colors, &Wfine_colors, &Wtexture, &Wshape);
}

You can convert the command line string arguments to double using the atof() function from stdlib.h. As I see you are using the TCHAR equivalents, there is a macro that wraps the correct call for UNICODE and ANSI builds, so you can do something like this (assuming your command line arguments are in the correct order)
#include "stdafx.h"
#include "shoes_sharedlibrary.h"
#include <iostream>
#include <string.h>
#include "mex.h"
#include <stdlib.h>
using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{
// ... initial code
// convert command line arguments to doubles ...
double wt1 = _tstof(argv[1]);
mwArray C(wt1);
double wt2 = _tstof(argv[2]);
mwArray F(wt2);
double wt3 = _tstof(argv[3]);
mwArray T(wt3);
// ... and so on ....
}
Note that argv[0] will contain the name of your program as specified on the command line, so the arguments begin at argv[1]. Then your command line can be something like:
yourprog.exe 0.123 0.246 0.567 etc.
