小米 USB 充電器

為了避免電子產品太多的我出門要帶太多充電器才能同時充電，當小米發表這個充電器的時候就好想買唷

單孔可以提供2.4A, 四個孔就降至7A

內容物很簡單，本體跟簡單的說明書

是台灣的企業帝聞代工的，品質有保障

HTC M7 換衣服

由於老媽的M7已經傷痕累累了，就決定幫它換個衣服，

有夠難拆的，外觀一顆螺絲都沒有，全部都是用膠黏的，拆背蓋真的很怕拆壞了

慘劇發生了，開機發現螢幕在拆的過程花屏了，只好再買個螢幕總成來換了

等了好久，螢幕總算來了，順利換上去囉

勒索軟體/病毒(綁架病毒)，中招了

當然不是我中招押，是別人中招後把我共用資料夾裡面的檔案都改掉了，

聽說過很多次，但還是第一次看到，所有檔案名稱都被修改了，副檔名也被修改為 Locky



當然，一定要留個訊息好讓你可以付贖金呀。

IIS Log 排程清除設定

網站上線久了，IIS Log 也會累積不少資料，佔用硬碟空間，
今天發現竟然大到 13 GB 的文字檔， 為了避免麻煩，
馬上找 Google 一下如何設定 Log 的清除使用 VBScript 進行刪除的動作

sLogFolder = "c:\inetpub\logs\LogFiles" iMaxAge = 30 'in days Set objFSO = CreateObject("Scripting.FileSystemObject") set colFolder = objFSO.GetFolder(sLogFolder) For Each colSubfolder in colFolder.SubFolders Set objFolder = objFSO.GetFolder(colSubfolder.Path) Set colFiles = objFolder.Files For Each objFile in colFiles iFileAge = now-objFile.DateCreated if iFileAge > (iMaxAge+1) then objFSO.deletefile objFile, True end if Next Next

 我是存在 C:\DeleteIISLog.vbs
 然後在命令提示字元執行就可以了cscript C:\DeleteIISLog.vbs

接著就去設定排程















這樣就只會保存 30 天的 Log Files

在 Server 有個很好用的遠端桌面功能，在 Windows 7 不是內建的，必須要安裝

Windows 7 Service Pack 1 (SP1) 的遠端伺服器管理工具

https://www.microsoft.com/zh-tw/download/details.aspx?id=7887

安裝完成後再去 Windows 功能中開啟，

 開啟後就可以在開始中找到遠端桌面了

一口氣把所有會連線的遠端多面都設定好，這樣以後就不用到處找 IP 跟帳密了

編碼轉換

這次遇到西歐語系編碼，系統無法正確儲存，只好寫個小工具來轉換編碼了。

先將檔案內容讀出來，GetEncoding(字碼頁)

string text = System.IO.File.ReadAllText(this.textBox1.Text, System.Text.Encoding.GetEncoding(1252));

然後另存檔案

System.IO.File.WriteAllText(this.textBox1.Text.Replace(".edi", "") + "_Unicode.edi", text);

再用記事本打開檔案就可以看到 WEIß 

大功告成

小孩遊戲床

這組小孩遊戲床的使用真方便，收起來後也有輪子方便帶著走，侄子都還沒出生，家裡越來越多他的用品了。

P2V Vhdx 磁碟縮小

要將實體機轉成 Hyper-V 的虛擬機器，首先先用到 Disk2vhd 這個工具進行轉換成虛擬磁碟 vhdx

https://technet.microsoft.com/zh-tw/sysinternals/ee656415.aspx

轉換後在 Hyper-V 開啟後發現硬碟空間配置，其實只需要 C 槽就好，D 槽完全都是空的

於是就先把 D 槽整個刪除，清出空間來，可是即便是這樣也無法將未分配的空間刪除

這時候就要使用到 Hyper-V 的功能編輯磁碟

選擇該虛擬磁碟後進行壓縮的動作

再將其掛載起來看看

已經成功的從1 TB 收到 100GB 了，也打之前的刪除磁區清掉

DHL Shipment Validation by C#

公司要導入跟物流的自動交互，如此就可以自動從 ERP 將資料傳到物流的系統，順便直接產生出提單 Label 直接可以貼在箱上。

DHL 提供的範例為 Java 的，只好問 Google 看看大家的經驗了，

經過好幾天的看文件，找範例，問廠商，總算可以順利的印出 Label 了。

string requestText//導入 XML 資料
WebRequest requestRate = HttpWebRequest.Create("https://xmlpitest-ea.dhl.com/XMLShippingServlet");//DHL 的測試環境
requestRate.ContentType = "application/x-www-form-urlencoded";
requestRate.Method = "POST";

using (var stream = requestRate.GetRequestStream())
{
var arrBytes = System.Text.ASCIIEncoding.ASCII.GetBytes(requestText);
stream.Write(arrBytes, 0, arrBytes.Length);

stream.Close();

}



WebResponse responseRate = requestRate.GetResponse();

var respStream = responseRate.GetResponseStream();

var reader = new StreamReader(respStream, System.Text.Encoding.ASCII);

string strResponse = reader.ReadToEnd();

respStream.Close();



XmlDocument xdoc = new XmlDocument();

xdoc.LoadXml(strResponse);



            XmlNodeList list = xdoc.GetElementsByTagName("OutputImage");



if (list.Count > 0)

{

//EPL2 直接傳給印表機進行列印

byte[] bytes = Convert.FromBase64String(list[0].InnerText.ToString());

IntPtr pUnmanagedBytes = new IntPtr(0);

int nLength = bytes.Length;

pUnmanagedBytes = Marshal.AllocCoTaskMem(nLength);

Marshal.Copy(bytes, 0, pUnmanagedBytes, nLength);

RawPrinterHelper.SendBytesToPrinter("DHL_Label", pUnmanagedBytes, nLength);

Marshal.FreeCoTaskMem(pUnmanagedBytes);

}

這邊會用到一個 Microsoft 網站只有找到 VB.Net 的，但網路上有人已經改成 C# 的 Class

這次訂票的經驗告訴我

訂票系統真的很複雜，很難寫，

光是一個網站的編碼都無法整合了

難怪我會看到亂碼~~~~機車哩，浪費我很多時間，只搶到給我媽跟阿姨們的，自己只能等加場了。

一直重新整理，一天三千次以上也不厭倦呀~~~~
