最近在做imap收信的功能，並把目標信件的附件存起來
沒想到發email這麼簡單，收email的處理卻是這麼的麻煩…
因為email中有太多種編碼方式了
我測試的code晚點po上來，先memo一下我找到不錯的code

vlc player播放rtsp
我的IP Camera位於192.168.27.101，且有設定密碼，所以用這樣的方式
不然他會跳出輸入帳密的視窗
rtsp://admin:admin123@192.168.27.101
如果有需要在linux下錄的話，可以用vlc或是ffmpeg
其中vlc需要安裝的東西比較多，所以需要到170MB的空間
ffmpeg只需要40幾MB就夠用了
ffmpeg -i rtsp://admin:admin123@192.168.27.101 -r 15 -vcodec copy -an -t 10 ./my-video.mp4

[python] wxpython + py2exe無法成功
之前都是做console的程式，用的也都是python內建的東西，因此py2exe都沒遇到什麼特別的問題
今天使用wxpython寫了個程式，想用py2exe包給別人用，發現包不起來!
出現這樣的訊息
No such file or directory: 'MSVCP90.dll'
網路上有人提到，把msvcp90.dll排除就可以了，如下(來源)：
python setup.py py2exe --dll-excludes=MSVCP90.DLL
執行檔做好了，又發現另一個問題，就是GUI視窗做好了，但是除了我要的windows視窗程式以外，也帶出來另一個console視窗，看起來很low.....
可以把
setup(console=['__main__.py'])
換成
setup(windows=['__main__.py'])
這樣就只會出現視窗，不會有console畫面了
另一個問題就是…整個要執行的程式資料夾很大，還不清楚怎麼縮小，如果有人研究出來了，再請跟我說一下~
---------- 2016/11/07 補上 -----------
因為上面的方式在沒有安裝MSVCP90.dll的電腦會有問題
補上新的方式解決，以下為主要二個檔案的內容
(參考資料為：連結1，連結2)
連同我的程式共三個檔案放在同一個資料夾中
在build完後，在[dist]中的就是我們要的執行檔，目前這個方法已經可以把所有需要的檔案都包成一個執行檔，要提供給別人非常方便
但我們會發現在同一個資料夾中還有另一個檔案[w9xpopen.exe]
這個檔案是為了在windows95, 98的電腦中使用sys.popen()這個指令用的
因為我們沒有想要相容於windows95, 98的電腦，只要XP以上能跑就可以了，所以這個檔案可以刪掉!!
把單一個執行檔提供給別人就好了!
