Dynamically linking python into my vc project - help required

[mrinalini]

Hi,

I am trying to embed python into my MFC application. I have done this
before by statically linking to the python lib. But I want to change
this now.
The idea is to take the information from the registry for the installed
version of python on the target machine. Then load python using
loadlibrary call and use the functions from python using pointers to
functions returned by GetProcAddress .

For example -

hModPython = AfxLoadLibrary("Python23.dll");

pFnPyRun_SimpleString *pFunction = NULL;
pFnPy_Initialize *pPy_Initialize = NULL;

pFunction = (pFnPyRun_SimpleString *)::GetProcAddress(hModPython,
"PyRun_SimpleString");
pPy_Initialize = (pFnPy_Initialize *)::GetProcAddress(hModPython,
"Py_Initialize");

try
{
pPy_Initialize();

if ( pFunction )
{
(*pFunction)("import sys"); // call the code
}
else
{
AfxMessageBox("unable to access function from python23.dll.",
MB_ICONSTOP|MB_OK);
}
}
catch(...)
{

}

And then I want to execute a python script through my MFC application
-

HANDLE hFile = CreateFile(file, GENERIC_READ, FILE_SHARE_READ,
NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);

DWORD dwSize = GetFileSize(hFile, NULL);
DWORD dwRead;

char *s = new char[dwSize +1];

ReadFile(hFile, s, dwSize, &dwRead, NULL);

s[dwSize] = '\0';

CString wholefile(s);

wholefile.Remove('\r');
wholefile+="\n";
CloseHandle(hFile);

pFnPy_CompileString *pFPy_CompileString = (pFnPy_CompileString
*)::GetProcAddress(hModPython, "Py_CompileString");

CString fl(file);

PyObject* pCodeObject = pFPy_CompileString(wholefile.GetBuffer(0),
fl.GetBuffer(0), Py_file_input);

if (pCodeObject != NULL)
{
pFnPyEval_EvalCode *pFPyEval_EvalCode = (pFnPyEval_EvalCode
*)::GetProcAddress(hModPython, "PyEval_EvalCode");

PyObject* pObject = pFPyEval_EvalCode((PyCodeObject*)pCodeObject,
m_Dictionary, m_Dictionary);
}


I am facing two problems here , though I want to link to python
dynamically I am required to include python.h for my code to compile
the following declaration.

PyObject* pCodeObject



I tried copying some of the python definitions including PyObject into
a header in my mfc app. Then it complies fine. but Py_CompileString call
fails. so finally I am unable to run script from my MFC application by
linking to python dynamically.

How can this be done ? Please help. Is there a different approach to
linking to python dynamically. Please could you write to me ?

Thanks in advance,
