Does Python's Ctypes C_char Work For Windows 64?
I'm trying to load a process list, and it functions correctly on 32bit python. However, on 64bit, I can't get the process name to list. The code is below. If I change szExeFile'
Solution 1:
Your PROCESSENTRY32 structure is wrong. This works for me:
class PROCESSENTRY32(Structure):
_fields_ = [ ( 'dwSize' , DWORD ) ,
( 'cntUsage' , DWORD) ,
( 'th32ProcessID' , DWORD) ,
( 'th32DefaultHeapID' , POINTER(ULONG)) ,
( 'th32ModuleID' , DWORD) ,
( 'cntThreads' , DWORD) ,
( 'th32ParentProcessID' , DWORD) ,
( 'pcPriClassBase' , LONG) ,
( 'dwFlags' , DWORD) ,
( 'szExeFile' , c_char * 260 ) ]
