CBitmap problem

Could anyone out there help me fix this dorky program?

#include <iostream>
#include <fstream>
#include <afxwin.h>
#include <windows.h>

using namespace std;

void getres(int &height, int &width);
BOOL MyLoadBitmap (std::string szFilename);

int main (int argc, char *argv[])
{
 int height, width;
    //CImage image;
 bool bbitmap;

 std::string inputfilename = "test.bmp";
 //ifstream inputfile (inputfilename.c_str());
    bbitmap = MyLoadBitmap (inputfilename.c_str());

 getres(height, width);

 return 0;
}

void getres (int &height, int &width)
{
 width = 640;
 height = 480;
}

BOOL MyLoadBitmap(std::string szFilename)
{
// ASSERT(szFilename);
 DeleteObject();

 HBITMAP hBitmap = NULL;
 hBitmap = (HBITMAP)LoadImage(NULL, (LPCSTR) szFilename.c_str(),
IMAGE_BITMAP, 0, 0,
  LR_LOADFROMFILE | LR_CREATEDIBSECTION | LR_DEFAULTSIZE);
 return Attach(hBitmap);
}
