* Why My tomcat complains:
 Unable to find a javac compiler;
 com.sun.tools.javac.Main is not on the classpath.
 Perhaps JAVA_HOME does not point to the JDK
- Try to add $JAVA_HOME/lib/tools.jar to tomcat JAVA-CLASSPATH.

- What is XMLTypes for in Data Base?
* we can use XML Type datatype on table columns. In short a record can have an XML attribute.
- How can i put the value of a sequence into a PL/SQL vairable in Oracle?
* Use 'DUAL' table: select XXXSEQ.CURRVAL into var from dual. 'DUAL' table can do much more than this, see the chapter 8-15 , DB92_sqlref.pdf
DUAL is a table automatically created by Oracle along with the data dictionary.
DUAL is in the schema of the user SYS, but is accessible by the name DUAL to all
users. It has one column, DUMMY, defined to be VARCHAR2(1), and contains one
row with a value ’X’. Selecting from the DUAL table is useful for computing a
constant expression with the SELECT statement. Because DUAL has only one row,
the constant is returned only once. Alternatively, you can select a constant,
pseudocolumn, or expression from any table, but the value will be returned as
many times as there are rows in the table.
- What http library can be used for programming C/C++ on Windows?
* use "WINHTTP"
- Why my VC complains that "winhttp.h" cannot be found???
* "The WinHTTP header file is "Winhttp.h", and the library file is "Winhttp.lib". If you are using the older SDK header files that come with Visual Studio 6.0, the project will not build correctly (for example, more recent type definitions such as 'DWORD_PTR' will be missing)."-http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winhttp/http/setting_internet_options_in_winhttp.asp

- HOW to build openssl on windows?
* see https://www.mmlab.cse.yzu.edu.tw/course/cns/doc/openssl.html, see lib
- What's the diference between '#include "XXX.h"' and '#include <XXX.h>'?
* Using '"' tell a C/C++ precompiler to look for header file in the search path, while using "<>" tell a C/C++ precompiler to  search in the standard library. see http://www.its.strath.ac.uk/courses/c/subsection3_13_3.html#SECTION00013300000000000000. NOTE, in VC7, search path is defined in "project attributes" dialog by feeding argument(s) like " /Ixxx", standard including path is defined in "tools->options->project".
* Why the pop-up menu won't disappear after created by TrackPopupMenu()???
为了使TrackPopupMenu函数在托盘环境中工作正常，你必须首先在拥有该弹出菜单
  的窗口中调用SetForegroundWindow函数。否则，当用户按下Esc键或在菜单以外单
  击鼠标时该菜单将不会消失。
