Embedding Python into C - importing modules -

-

I'm having trouble using embedded Python for C - whenever I try to use imported module I get one:

Unsupported exception on 0x1e089e85 in PythonIncl.exe: 0xC0000005: Access violation location 0x00000004.

error is in PyObject_GetAttrString () method and documentation is not much help. I have also tried to use tutorials from IBM, but always have the same access Get infringement.

The example code for one of the following tutorials, which I can not seem to work on, is that wrong here?

The C-code (in a main file): 

  #include & lt; Python H & gt; Int main () {PyObject * strret, * mymod, * strfunc, * strargs; Four * seistrets; Py_Initialize (); Mymod = PyImport_ImportModule ("reverse"); Strfunc = PyObject_GetAttrString (mymod, "rstring"); Strargs = Py_BuildValue ("(S)", "Hello World"); Strret = PyEval_CallObject (strfank, strings); PyArg_Parse (strret, "s", and cstrret); Printf ("reverse string:% s \ n", cstrret); Py_Finalize (); Return 0; }   
 Python code (in a file called reverse.py, same folder):  
  def rstring (s): i = len (S) - 1t = '' while (i> gt; -1): T + = s [i] i - = 1 return t   
 I MSVS2008, Python 2.7  Some references: I am trying to embed a small dragon script which uses open opc, which is in a large number of programs and wants to transfer data between the two. However, I have failed in the Proof of concept exam with basic examples already.   
 
 
  PyImport_ImportModule  Calls: This fails and returns  NULL < / Code>. The reason for this is by default, the current directory is not in the search path. Add  
  PySys_SetPath ("."); // first .. mymod = PyImport_ImportModule ("reverse");   
 To add the existing directory to the module search path and work your example.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...
