用到 Python，首先你肯定得装一个Python吧，用3.x的

创建一个.py文件

说明：需要引用pythoncom (这个需要pip install pywin32 )

import pythoncom
class PythonUtilities:

_public_methods_=['SplitString']
_public_methods_ = ['httpBom']
_reg_progid_='PythonDemos.Utilities'
_reg_clsid_=pythoncom.CreateGuid()

def SplitString(self, val, item=None):
import string
if item !=None:
item=str(item)
val=str(val)
return val.split(item)

def httpBom(self):
return "hhh"

if __name__=='__main__':
print ('Registering COM server...')
import win32com.server.register
win32com.server.register.UseCommandLine(PythonUtilities)
然后在VB中就可以使用Python中的方法了

Private Sub Command1_Click()
Set PythonUtils = CreateObject("PythonDemos.Utilities")
' response = PythonUtils.SplitString("Hello from VB My name is Leo Liu")
' For Each Item In response
' List1.AddItem Item
' Next
MsgBox PythonUtils.httpBom
End Sub
最终的使用方法

cmd 中输入： Python PythonDemos.py

然后VB就可以使用Python这个类中发方法了

如果想要注销这个COM

python PythonDemos.py --unregister

然后将这个文件打包成 exe:

安装 pin install pyinstaller

Pyinstaller -F WFJieKouPY.py #打包成多文件
Pyinstaller -D WFJieKouPY.py #打包成单文件

注意：需要引用 import win32timezone 否则报错

import pypyodbc
import os
import requests
import pythoncom
import json
import win32com.server.register
import win32timezone
class PythonUtilities:
    _public_methods_ = ['FindBoms', 'SendBoms', 'test', 'GetData']
    _reg_progid_ = 'WFJieKouPY.Utilities'
    _reg_clsid_ = pythoncom.CreateGuid()
