手札的圖片共享目錄約三~四天會無法開啟(\\192.168.0.7 直接掛掉)
對應的服務 Server 會無法重新開啟
在 Windows 2008 Server 將 SMB2.0 => SMB 1.0 方法
參考連結 http://www.petri.co.il/how-to-disable-smb-2-on-windows-vista-or-server-2008.htm
Client 關閉
sc config lanmanworkstation depend= bowser/mrxsmb10/nsi
sc config mrxsmb20 start= disabled
Client 重開
sc config lanmanworkstation depend= bowser/mrxsmb10/mrxsmb20/nsi
sc config mrxsmb20 start= auto
Server
HKLM\System\CurrentControlSet\Services\LanmanServer\Parameters\Smb2 => 設為 Dword 0
需重開機，開機完後 Client 連不到也需重開
設好後，這些背後靈又出現要設了。
HKLM\System\CurrentControlSet\Services\LanmanWorkstation\Parameters\MaxCmds => 500 以上
HKLM\System\CurrentControlSet\Services\LanmanServer\Parameters\MaxMpxCt =>500 以上
HKLM\System\CurrentControlSet\Services\LanmanServer\Parameters\MaxWorkItems => 5000以上
設完後有以下現象。
系統管理工具=>共用與存放管理=>管理工作階段
每個連線的開啟檔案數是會增加減少跳動的，在SMB2.0下僅會緩慢增加
// 當Form沒有傳入 ArticleCategory, 則回傳空值
string strCategoryIDs = Request.Form["ArticleCategory"] == null ? string.Empty : Request.Form["ArticleCategory"];
-->
string strCategoryIDs = Request.Form["ArticleCategory"] ?? string.Empty;
顯示網路狀態:
netsh interface tcp show global
關閉 Auto Tuning:
netsh interface tcp set global autotuning=disabled
開啟 Auto Tuning:
netsh interface tcp set global autotuningl=normal

嘿嘿 .. 問題又發生了, 看來沒什麼效果..
pre-revprop-change.bat 的內容如下:
if "%4" == "svn:log" exit 0
echo Property '%4' cannot be changed >&2
exit 1
Sample 如下:
Imports System.Drawing.Printing

Dim TotalPage As Int32 = 0

Ex:
Dim Conn As SqlConnection = UW.SQL.GetOpenedConnection
Dim Tran As SqlTransaction = Conn.BeginTransactionTry
Dim C As Int32 = UW.SQL.GetSingleValue("Select Counter From TableA Where Id = 1", Tran)
C = C + 1
UW.SQL.executeSQL("Update TableA Set Counter = " & C & " Where Id = 1", Tran)
Tran.Commit()
Catch ex As Exception
Tran.Rollback()
UW.WU.DebugWriteLine(ex.ToString, True, True)Finally
If Conn.State <> ConnectionState.Closed Then
Conn.Close()
End IfEnd Try
以上的程式由兩個 Session 同時執行時, 並不能保証 Counter 會被加 2
若是要保証兩個 Session 都會把 Counter 加一(總共加 2), 要把以下這一行
Dim C As Int32 = UW.SQL.GetSingleValue("Select Counter From TableA Where Id = 1", Tran)
改為
Dim C As Int32 = UW.SQL.GetSingleValue("Select Counter From TableA With(XLock) Where Id = 1", Tran)

在 IE 中很簡單就能辦到, 至於其他的瀏覽器......目前還沒這個需求, 先擱著~~~~~
var img = document.getElementsByTagName("IMG")[0]; var rng = document.body.createControlRange(); rng.add(img); rng.execCommand('Copy');真是簡單到不行! 可以看出 Microsoft 當初那群規劃設計 IE 的人實在是太厲害了!!
