Python embedded in C ++/C, etc.

Take python2.6 as an example;
 

 
1.PythonSource code, Open and compile python26.dll, python26.lib, python26_d.lib, and python26_d.dll. add them to the lib directory and put them in the System32 folder.
 

 
2. You can proceed with the followingCodeNow.
 

 
Additional point: Get the currentProgramRunning directory:
 

Tchar buffer [bufsiz];

DWORD dwret = getcurrentdirectory (bufsiz, buffer );

Widechartomultibyte (cp_acp, wc_compositecheck, (buffer),-1, CH, sizeof (CH), null, null );

 
// This is the same as the following three statements.
 

// Ah ''' Shen Na, tchar, cstring char * is still in the fog of the cloud. You have to check it again...
 

 
Cstring strpath;
 

 
Getcurrentdirectory (max_path, strpath. getbuffer (max_path ));
 

 
Widechartomultibyte (cp_acp, wc_compositecheck, (strpath. getbuffer (strpath. getlength () + 1 )),
 

 
-1, CH,Sizeof(CH), null, null); // convert wchar_t * To char *... you can refer to the previous log about Unicode and ASCI
 

 
Strpath. releasebuffer ();
 

 
IntLen = strlen (CH );
 

 
StringFilename ="\ Test. py";
 

 
For(IntI = 0; I <FILENAME. Length (); I ++)
 

 
Ch [Len ++] = filename [I];
 

 
Ch [Len] = '\ 0 ';
 

Locate the. py file path you are looking.
 

 
The initial path of the pyobject below is different from the default debug folder of ..
 

 
It is also self-seeking troubles ..
 

 
3. Two embedding methods of Python: one is to directly call an existing py file.
 

Pyobject * pyfile = pyfile_fromstring (CH ,"R");

If(Pyfile = NULL)

{Printf ("Exit 1"); System ("Pause");Return1 ;}

File * f = pyfile_asfile (pyfile );

If(F = NULL)

{Printf ("Exit 2"); System ("Pause");Return1 ;}

Pyrun_anyfileex(F ,"Test. py", 0 );

 
The other is to directly Insert the statement for execution.
 

 
String pythoncode ="Print ('Hello world, I am python! ')";
 

 
Pyrun_simplestring (pythoncode );
 

 
Code:
 

 
// Pythonplugintest. cpp:
 

//

Pyobject * pyfile = pyfile_fromstring (CH ,"R");If(Pyfile = NULL) {printf ("Exit 1"); System ("Pause");Return1;} file * f = pyfile_asfile (pyfile );If(F = NULL) {printf ("Exit 2"); System ("Pause");Return1;} pyrun_anyfileex (F ,"Test. py", 0 );// Run the command directly. The command is a string. Note that parentheses must be added to Python 3.1.1.
