outlook 自動儲存尚未傳送的郵件

有的使用者不知是不是信件開太多,pst又掛載一大堆,三不五時outlook就會突然都沒反應,雖然從工作管理員查看,cpu還是有在處理,但每封信或是outlook主視窗上面所有的鈕都無反應,只能強制關係。

這時後如果有些信寫到一半還沒寄出會存成草稿,就會怕資料不見。 

outlook裡面有一個自動存到草稿的功能,就在"選項"-->"郵件"裡面,可以設定幾分鐘內沒寄出的信自動儲存。

如果是正常方式關閉outlook,系統會問你,要不要存,你選擇不存,就算超過設定的時間,也不會存到草稿。

但若不小心outlook當掉,超過時間的那些信,其實就可直接在開啟outlook後在草稿匣內找到,這功能還蠻實用的。

電腦登入後都會啟動一個程式Bright Data

下載格式工廠來做一些影片轉檔時,發現電腦右下角工具列,多了一個程式"Bright data",不知是什麼東西。



每次登入電腦就會啟動,在windows啟動列表中,卻找不到這個項目,電腦的程式安裝清單內也沒有。

查了一下才發現這是做網路代理的程式,但被被不肖份子濫用,使個人設備成為攻擊跳板。

https://www.cc.ntu.edu.tw/chinese/cert/cert20230815.asp  這個網頁有提供移除方法。

簡單的說就是用Autoruns.exe或procexp.exe去找搜尋net_updater64.exe、net_updater32.exe及brightdata.exe或服務Brightdata Service是否持續運行,找到就把這個程式刪除。


When downloading Format Factory to perform some video conversions, I noticed a program called "Bright data" appearing in the toolbar at the bottom right corner of my computer screen. I was unsure what it was.


Every time I logged into my computer, it would start up, but I couldn't find it in the Windows startup list, nor was it listed in the installed programs on my computer.


After some investigation, I discovered that it's a program used for internet proxies, but it has been abused by malicious actors, turning personal devices into attack proxies.


This webpage (https://www.cc.ntu.edu.tw/chinese/cert/cert20230815.asp) provides a method for removing it.


In short, you can use Autoruns.exe or procexp.exe to search for net_updater64.exe, net_updater32.exe, and brightdata.exe, or check if the Brightdata Service is continuously running. Once found, you can delete the program.

ESXI 7.0 安裝好WINDOWS 2019 無法使用ctrl alt del

剛裝好一台 ESXI 7.0,在上面建好一台win2019的虛擬機後,要傳送ctrl +alt +del做登入時,都沒反應。

之前也遇過,不過那是做了windows更新,裝到了vmtool造成的,這次卻是裝好win2019就沒辮法登入了。

後來發現是因為裝好後,通常都會直接選擇"開啟瀏覽器主控台",然後操作,有時後傳送ctrl +alt +del會失效。

改用"啟動遠端主管台"來傳送ctrl +alt +del,就可以了。



Just installed an ESXi 7.0 server, and after setting up a Windows Server 2019 virtual machine on it, I found that pressing ctrl + alt + del to log in doesn't work.

I've encountered a similar issue before, usually caused by Windows updates or installing VMtools. However, this time, even after setting up Windows Server 2019, I couldn't log in.

Later, I realized that after installation, I typically chose "Open Browser Console" directly, and sometimes sending ctrl + alt + del wouldn't work.

Switching to "Launch Remote Console" to send ctrl + alt + del solved the issue.

利用python做台指期當沖自動交易~~失敗

 利用python做台指期當沖自動交易~~跑了快三個月吧。

程式本身沒什麼問題,大概就是停損出場會滑價,其他方面執行上是沒什麼問題。

但失敗了,因為策略太爛了,雖然風報比把2:1,但太常停損了,勝率太低,所以最重要的還是策略,程式只是個輔助。

現在就停止當沖,在好好想想策略吧。

EDGE開啟pdf檔直接另存

 有時後用EDGE在瀏覽網頁時,看到一些PDF檔,EDGE可以直接顯示,不用另存成PDF檔,再用 PDF reader開啟。

如果希望直接存在PDF檔,不要在EDGE中直接開啟,可以調整機碼來達行。

機碼位置如下,如果沒有的話,可以自行手動新增,設定好要重開機才會生效。



Sometimes, when browsing web pages using EDGE, you may come across PDF files that EDGE can display directly without the need to save them as PDF files and then open them with a PDF reader.

If you prefer to save the PDF file directly instead of opening it in EDGE, you can adjust the registry to achieve this.

If you cannot find this registry entry, you can manually add it yourself and ensure that the changes take effect after restarting your computer.

WIN10 安裝framework 3.5失敗 0X800F0954

 win10在裝framework 3.5一直失敗,錯誤代碼是 0X800F0954 。

有人說要去HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU\ 裡面調機碼,把UseWUServer的值改成0。

但發現自己的電腦裡並沒有這個機碼,所以就手動新增,設定好重開機,就可以成功安裝。



Windows 10 fails to install Framework 3.5, and the error code is 0X800F0954.

Some suggest modifying the registry key at HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU\ by changing the value of UseWUServer to 0.

However, it was found that the registry key was not present on the computer, so it was manually added. After configuring and restarting, the installation was successful.

WINDOWS複製資料夾 包含權限

 如果要把A資料夾整個完整複製,包含裡面的權限跟所有資料,然後名稱變成B資料夾。

而且B資料夾本身的權限必須跟A資料夾相同,可以使用robocopy這個內建指令。

執行指令前要確認B資料夾不存在,再執行指令。

指令: robocopy D:\A D:\B /E /COPYALL



If you want to completely copy the entire A folder, including its permissions and all data inside, and rename it to B folder, you can use the built-in command robocopy.

Ensure that the B folder does not exist before executing the command.

Command: robocopy D:\A D:\B /E /COPYALL

WINDOWS 檔案總管內點選檔案時速度很慢

使用者反應,他在檔案總管裡,開啟一個pdf檔案時很正常,然後再點其他pdf檔案後,檔案不會馬上開啟,要等個幾十秒,他認為是程式有問題。

把程式重新安裝後,還是一樣,後來發現在檔案總管內,是有開啟預覽窗格的功能,如果這個功能關閉,連續開啟不同檔案時,就不會有緩慢的問題了。




User feedback indicates that when he opens a PDF file in File Explorer, it works fine. However, when he tries to open another PDF file after that, the file doesn't open immediately; instead, it takes several seconds. He believes there is an issue with the program.

Even after reinstalling the program, the problem persists. Later, it was discovered that within File Explorer, there is a feature to open a preview pane. When this feature is disabled, there is no longer a delay issue when opening different files consecutively.

python py轉exe後執行失敗

 最近在更新一個python檔案,更新完要透過pyinstaller轉成exe,會用到pandas跟openpyxl兩個套件。

轉出來後卻無法執行,錯誤訊息是說numpy有問題(Error importing numpy: you should not try to import numpy from....)

這個是在裝pandas時自動裝進來的,研究到最後就是python的版本太新(3.9.x),重新建一個虛擬環境,降到3.6就排除這個問題了。

但卻產生另一個錯誤(ImportError: Missing optional dependency 'xlrd'. Install xlrd >= 1.0.0 for Excel support Use pip or conda to install xlrd)

查到最後也是版本的問題,最快的方法就是重做一個虛擬環境,python是3.8.1,然後pip install pandas跟openpyxl,xlrd跟numpy的問題就沒了。



I have been updating a Python file recently, and after the updates, I need to convert it to an executable using pyinstaller. The script relies on two packages, pandas and openpyxl.

However, after the conversion, the executable cannot run, and the error message indicates an issue with numpy (Error importing numpy: you should not try to import numpy from....). It turns out that this issue arose because of the version of Python being too new (3.9.x) when installing pandas. I resolved this by creating a new virtual environment and downgrading to Python 3.6.

However, this led to another error (ImportError: Missing optional dependency 'xlrd'. Install xlrd >= 1.0.0 for Excel support. Use pip or conda to install xlrd). After investigation, I found that this was also a version-related problem. The quickest solution was to create a new virtual environment with Python 3.8.1 and then install pandas and openpyxl using pip. This resolved the issues with xlrd and numpy.

solidworks 2015 無法點兩下檔案直接開啟 swshellfilelauncher 嘗試開啟您的檔案時發生錯誤

 solidworks 2015 安裝好之後,程式可正常開啟,開啟舊檔/新檔都正常。

但是如果在資料夾內對著檔案直接連點兩下開啟時,solidworks有啟動,但會跳出一個swshellfilelauncher 的錯誤視窗,內容是嘗試開啟您的檔案時發生錯誤


解法就是對著檔案按右鍵,選擇用"solidworks launcher"開啟檔案。
如果還是不行,一樣是對著檔案按右鍵,選擇預設程式,然後到solidworks的安裝目錄中找到swshellfilelauncher ,設定用該程式來開啟圖檔,就可以了。




After installing SolidWorks 2015, the program opens successfully, and both opening existing files and creating new files work as expected. However, if you double-click a file directly within a folder, SolidWorks launches but displays an error window titled "swshellfilelauncher," stating that an error occurred while trying to open your file.

The solution is to right-click on the file, choose "Open with SolidWorks Launcher." If this doesn't resolve the issue, right-click on the file again, select "Open with," and navigate to the SolidWorks installation directory to find swshellfilelauncher . Set it as the default program for opening image files, and the problem should be resolved.
