❶ JS代碼高手幫我看段JS代碼，幫我分析下這些代碼具體是什麼含義
一個打包，一個解包，
❷ c++中藍牙編程的庫類
安裝PSDK就可以用了，之前有寫過一個類在MFC裡面調用，並能成功與藍牙手機通信，只不過是非標準的藍牙協議。代碼如下：

❸ ORACLE PL/SQL代碼錯誤
BTH DATE, 這里多了個逗號。語法檢查不通過，把這個去了。
❹ 木馬查殺時顯示C:\HP\HPQWare\BTHHost\PostUser.bat是風險項，想問一下可以刪除嗎
從名字看是個批處理文件，可以刪除的。你可以用記事本打開看下代碼
❺ 求EXCEL代碼：表一中不確定幾行，除標題行外；添加記錄到表二最下面。
樓主沒有說明數據是從表一的哪裡開始，添加到表二的下面又是哪一列開始，難以下手
假設復製表一的數據到表二的A列開始粘貼，代碼如下：
Sub DataCopy()
Dim bth%
bth = Application.InputBox("請輸入表一的標題行數", "提示", 1, , , , 1)
Worksheets("表一").UsedRange.Offset(bth).Copy
Worksheets("表二").Range("a" & Worksheets("表二").Rows.Count).End(xlUp).Offset(1, 0).PasteSpecial xlPasteValues
Application.CutCopyMode = False
End Sub
❻ windows C++通過藍牙連接安卓手機。電腦端必須用C++，不能使用Java，C#等語言。我的代碼如下：
addressFamily
Address family of the socket. This member is always AF_BTH.
