Problem with PyRun_SimpleFile and MFC Application

[Susanne]

Hello!

In have embedded python into my MFC application.
It works fine using the PyRun_SimpleString method, giving it a string with
some simple commands.

When i am using PyRun_SimpleFile instead, my application crashes.

I have also created a console application. There i also call PyRun_SimpleFile.
The console application executes the given script.

My code looks like the following:

**********************************
MFC-Application:
**********************************

Py_SetProgramName("testclient");

/* Initialize the Python interpreter. Required. */
Py_Initialize();

curMode = DEBUG_MODE;

//**** is running!!!!*****
//CString command = "import CORBA; CORBA.SetTPData();";
//PyRun_SimpleString(command);
//CORBA is my python module, SetTPData a method of this modul
//in SetTPData i open an AfxMessageBox, so thats why i know that
//it works

//path of my file
char * filename2 = "C:\\cvsroot\\OCI-TestClient\\projects\\main\\tao\\test.py";
FILE *fp =fopen(filename2,"r");

int result;

if(fp !=NULL)
{
//does not work :-(
result = PyRun_SimpleFile(fp,filename2);
fclose(fp);
}

Py_Finalize();

****************************************
Now the code of the console application:
****************************************

/* Pass argv[0] to the Python interpreter */
Py_SetProgramName(argv[0]);

/* Initialize the Python interpreter. Required. */
Py_Initialize();

//create instance of my class
PythonExtension * pythi = new PythonExtension();

//init my module (not the same module like in MFC app)
pythi->initspam();

char * filename2 = "C:\\cvsroot\\OCI-TestClient\\projects\\main\\tao\\test.py";
FILE *fp =fopen(filename2,"r");
int result;

//works fine, only says, that there is no modul called CORBA
//see below
result = PyRun_SimpleFile(fp,filename2);
printf("Result: %d",result);

**********************
My python script file:
**********************

import CORBA;
CORBA.SetTPData();

//...

************************

So, does anyone of you have an idea, what i am doing wrong in my mfc app?

Somebody in a relevant newsgroup probably does. comp.lang.c++ is
NOT one of them. Perhaps along with the Python one that you used,
an MFC newsgroup can help. comp.os.ms-windows.programmer.tools.mfc
and microsoft.public.vc.mfc are the two that spring to mind.

PyRun_SimpleFile() reportedly (and I can second that) when certain compiler
flags are different from the pythonxx(_d).dll. Try setting your Project
Settings -> C/C++, Code Generation -> "Use runtime library" - to "(Debug)
Multithreaded DLL"

(Don't know if or how this affects any of your MFC stuff though)

Hope this helps,

Yes, this will be the OPs issue. However, you don't always use the
debug CRT - the important thing is to use the *same* CRT as Python
itself. So a release build of your app/extension *must* be the
non-debug in a DLL, and a debug build must use the debug in a DLL.

This is all OT in comp.lang.c++. Please trim your cross-posting.

Hello together,

after reading your comments, i looked, which configuration
im using in my console app. Its a release app.
Than i tried to run it as a debug app and now the
programm crashes like my mfc app.

So the hint with the debug dll was good.

But how can i get this dll?
I don't have the python source code and i also
can't find it in the internet.
So there is no way to create it by myself.

Can anyone of you help me again??

Thanks
Susanne
