Consult the Python call fastreport DLL-CodePudding

I'd like to call in python fastreport. DLL, says below my several attempts,
1, the first to find the CLR example is used to import, in this sentence the from FastReport import * error: ImportError: No module named 'FastReport'
Is 2, and later began with DLL encoding (ANSI/unicode) and release (32/64), 64, found that python is indeed a DLL is 32-bit, later changed python3.5.4 32 bit, but still won't do
3, finally tried MSVCRT DLL can be successful, that environment should be no problem, may be obtain right
4, try ctypes way of obtaining or not, here is my code

The import ctypes
LibHandle=ctypes. Windll. Kernel32. LoadLibraryW (' MSVCRT. DLL)
Lib=ctypes. CDLL (None, handle=libHandle)
Lib. Printf (b "hello world!" )

LibHandle=ctypes. Windll. Kernel32. LoadLibraryW (' FastReport. DLL)
Lib=ctypes. WinDLL (None, handle=libHandle)
The from FastReport import *
The report=report ()
Report. The Load (" bq. Usd ")
Report. The Show ()
The result is

Result or not, I look at the others will easily tuned out, why I always say there is no this fastreport this module? Now really is no way out, want to see any friends encountered similar problems, help to raise a point of thinking, first thank you

Ah, I here can't use the same code, check the methods are tried, still won't do

Do you know FastReport. DLL in the function definition? Is a pure C language

CodePudding user response:

Try that?
When used, parameters to agree with C function declaration type, in addition to None, int, long, Byte String, Unicode String, can not directly use Python data types, must transform

 
The import ctypes 

DLL=ctypes. CDLL (" MSVCRT DLL ") 
DLL. Printf (" hello world "b) 

The report=ctypes. CDLL (" FastReport. DLL ") 
Report. The report () 
Report. The Load (" bq. Usd ") 
Report. The Show ()

Thank you for reminding me, fastreport. DLL is c # types of DLL, use the method of pythonnet CLR inside is more, but I is the CLR, or an error: ImportError: No module named 'fastreport'
Also, I tried the second method, you said there is no the from FastReport import * this sentence, not introduced, the inside of the Report should not be used

I the printf is used, the example to prove that I am in front of the environment should be no problem

The from FastReport import *
It sure is wrong, the environment there is no FastReport this module, you sure others use the same with you?
