I suspect the filename's slashes are getting escaped. It should end up
looking like c:/foo/foo.png or like "c:\\foo\\foo.png" You could use
itksys to convert these paths from the native windows style paths.

#include "itksys/SystemTools.hxx"

std::string fname = strFile
itksys::SystemTools::ConvertToUnixSlashes(fname);
if (!itksys::SystemTools::FileExists(fname.c_str()))
  {
  std::cerr << fname << " doesn't exist.. check again" << std::endl;
  }
