Windows自動啟動程序的十大藏身之所

Windows啟動時通常會有一大堆程序自動啟動。不要以為管好了「開始→程序→啟動」菜單就萬事大吉,實際上,在Windows XP/2K中,讓Windows自動啟動程序的辦法很多,下文告訴你最重要的兩個文件夾和八個註冊鍵。   
一、當前用戶專有的啟動文件夾   這是許多應用軟件自動啟動的常用位置,Windows自動啟動放入該文件夾的所有快捷方式。用戶啟動文件夾一般在:\Documents and Settings\<用戶名字>\「開始」菜單\程序\啟動,其中「<用戶名字>」是當前登錄的用戶帳戶名稱。   

二、對所有用戶有效的啟動文件夾   這是尋找自動啟動程序的第二個重要位置,不管用戶用什麼身份登錄系統,放入該文件夾的快捷方式總是自動啟動——這是它與用戶專有的啟動文件夾的區別所在。該文件夾一般在:\Documents and Settings\All Users\「開始」菜單\程序\啟動。
  
三、Load註冊鍵   介紹該註冊鍵的資料不多,實際上它也能夠自動啟動程序。位置:HKEY_CURRENT_USER\Software\Microsoft\WindowsNT\CurrentVersion\Windows\load。   

四、Userinit註冊鍵   位置:HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon\Userinit。這裡也能夠使系統啟動時自動初始化程序。通常該註冊鍵下面有一個userinit.exe,如圖一,但這個鍵允許指定用逗號分隔的多個程序,例如「userinit.exe,OSA.exe」(不含引號)。 圖一   

五、Explorer\Run註冊鍵   和load、Userinit不同,Explorer\Run鍵在HKEY_CURRENT_USER和HKEY_LOCAL_MACHINE下都有,具體位置是:HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\Run,和HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer\Run。   

六、RunServicesOnce註冊鍵   RunServicesOnce註冊鍵用來啟動服務程序,啟動時間在用戶登錄之前,而且先於其他通過註冊鍵啟動的程序。RunServicesOnce註冊鍵的位置是:HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunServicesOnce,和HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServicesOnce。   

七、RunServices註冊鍵   RunServices註冊鍵指定的程序緊接RunServicesOnce指定的程序之後運行,但兩者都在用戶登錄之前。RunServices的位置是:HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunServices,和HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices。   

八、RunOnce\Setup註冊鍵   RunOnce\Setup指定了用戶登錄之後運行的程序,它的位置是:HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce\Setup,和HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce\Setup。   

九、RunOnce註冊鍵   安裝程序通常用RunOnce鍵自動運行程序,它的位置在HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce和HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce。HKEY_LOCAL_MACHINE下面的RunOnce鍵會在用戶登錄之後立即運行程序,運行時機在其他Run鍵指定的程序之前。HKEY_CURRENT_USER下面的RunOnce鍵在操作系統處理其他Run鍵以及「啟動」文件夾的內容之後運行。如果是XP,你還需要檢查一下HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnceEx。   

十、Run註冊鍵   Run是自動運行程序最常用的註冊鍵,位置在:HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run,和HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run。HKEY_CURRENT_USER下面的Run鍵緊接HKEY_LOCAL_MACHINE下面的Run鍵運行,但兩者都在處理「啟動」文件夾之前。

DB2 JDBC Connection

DB2 Connection Methods

// COM.ibm.db2.jdbc.app.DB2Driver uses db2java.zip and create dbname ODBC in OS
String JDBC_DRIVER = "COM.ibm.db2.jdbc.app.DB2Driver";
String CONNECTION_URL = "jdbc:db2:dbname";

// com.ibm.db2.jcc.DB2Driver uses db2jcc.jar
String JDBC_DRIVER = "com.ibm.db2.jcc.DB2Driver";
String CONNECTION_URL = "jdbc:db2://172.0.0.1:50000/dbname";
Class.forName(JDBC_DRIVER).newInstance();
Connection con = DriverManager.getConnection(CONNECTION_URL,CONNECTION_USERID, CONNECTION_PASSWORD);

//Using Connection pool. Config "jdbc/dbsource" in Application Server
InitialContext ctx = new InitialContext();
DataSource ds =(DataSource)ctx.lookup("jdbc/dbsource");
con = ds.getConnection();

//Using Connection pool with Ref Resource. Config "jdbc/dbsource" in Application Server
1.Config resource ref. in application server. following will be generated in web.xml

<resource-ref id="ResourceRef_1156216203871">

SUBST [drive1: [drive2:]path]
SUBST drive1: /D
drive1: Specifies a virtual drive to which you want to assign a path.
[drive2:]path Specifies a physical drive and path you want to assign to virtual drive.
/D Deletes a substituted (virtual) drive.

Type SUBST with no parameters to display a list of current virtual drives.

e.g.
subst z: c:\temp

subst z: /d

Locale Setting Tips

1. For Sametime to show chinese character
"Regional and Laugage Options" --> "Advanced" --> "Language for non-Unicode programs"--> "Chinese (Taiwan)"

2.For ES in Websphere
"Regional and Laugage Options" --> "Regional Options" --> "Standards and formats" --> "English (United States)"

3.For DB2 Configuration Assistant
"Regional and Laugage Options" --> "Advanced" --> "Language for non-Unicode programs"--> "Chinese (Taiwan)/English (United States)"
"db2jds.exe problem" will be happened while the language is "Chinese (Hong Kong S.A.R.)"

Usage of CLOB

public String generatePaymentNotice(String pEmail_status, String pInclude_header_ind) throws Exception {
Vector lvParaValue = new Vector();
String lvSQL = "select pkg_cg_enrolment.Sf_Cg_Gen_Payment_Notice(?,?,?,?,?) as result from dual";
lvParaValue.add(this.getYear());
lvParaValue.add(this.getOrg_id().toUpperCase());
lvParaValue.add(this.getOrg_name());
lvParaValue.add(pEmail_status);
lvParaValue.add(pInclude_header_ind);
ResultSet lvRs = db.executeSelect(lvSQL, lvParaValue);
// CHING. use oracle.sql.CLOB instead of java.sql.Clob for WebSphere Deployment.
// java.sql.Clob tempClob = null;
oracle.sql.CLOB tempClob = null;
if (lvRs != null && lvRs.next()) {
tempClob = (oracle.sql.CLOB) lvRs.getObject("result");
}
lvRs.close();
if (tempClob.length() > 1) {

fromUnicode = sun.io.CharToByteConverter.getConverter("Big5");
return new String(fromUnicode.convertAll(tempClob.getSubString(1 , (int) tempClob.length()).toCharArray()));
} else {
return "";
