群益api– python 串接使用 pythonnet

群益api 版本: 2.13.6
python 版本: 2 or 3 64bit
用pythonnet, 一開始串SKCOM, 結果一直沒有成功, 想說要不要換 ironpython 試試
後來想說改串 Interop.SKCOMLib 沒想到卻成功了

目前遇到的問題是 Event Callback 時候沒辦法下中斷點，
另外在 Event 裡面再去呼叫 Com 的程式，好像會遇到不明的錯誤
所以全部改為使用 queue 在外部實作功能

特別一提的是 呼叫 SKQuoteLib_GetStockByIndex 輸入的的 STOCK 變數，輸出卻是不同一個(?)
所以我就在 SKCOMWapper 裡面也宣告了一個 STOCK, 每次都使用同一個就好了

在測試本程式的時候需要 更改 帳號/密碼, dll位置我是放在同一個目錄下的 dll/x64/
宣告 StockBot 時候，初始要查詢的 股票編號

switch.py 就不另外給了，網路上也是方便可以查詢的到原始碼
本身我 python 也是初學，目前先寫到可以登入、查詢股票

有些人問了 switch.py, 這裡有一個範例可以使用
https://github.com/soarpenguin/python-scripts/blob/master/switch.py
另外 pythonnet 使用群益的新版目前會遇到問題, 請參考網址, 改用 comtypes
