TKINTER连接到MS Access数据库

Question

我正在尝试使用TKINTER进行GUI选择MS Access数据库。我遇到了一个错误：“一般错误无法打开进程0xcb8螺纹0x39b8 dbc 0x1D234678“指向连接线的进程0xcb8 thread 0x39b8 dbc 0x39b8 dbc 0xcb8 thread 0xcb8 thread”的通用错误。为什么这不起作用。

import pandas as pd
import pyodbc
import numpy as np
from tkinter import *
from tkinter import ttk, filedialog
from tkinter.filedialog import askopenfile
import os
 
# Create an instance of tkinter frame
win = Tk()

# Set the geometry of tkinter frame
win.geometry("700x350")

def open_file():
   file = filedialog.askopenfile(mode='r', filetypes=[('MS Access File', '*.accdb')])
   if file:
      filepath = os.path.abspath(file.name)
      Label(win, text="The File is located at : " + str(filepath), font=('Aerial 11')).pack()
      conn = pyodbc.connect(r'Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ = ' + filepath)
      qry=("select * from Table1")
      dataf = pd.read_sql(qry, conn)
      conn.close()      

# Add a Label widget
label = Label(win, text="Browse for file", font=('Georgia 13'))
label.pack(pady=10)

# Create a Button
ttk.Button(win, text="Browse", command=open_file).pack(pady=20)

win.mainloop()
