Installed ubuntu 9.10 on laptop. The installation package is an iso file for CD-image, then I have to record it via InfraRecorder to write to DVD-R/W since a commercial software refused to write CD-image into DVD. The installation process is simple. I have to change my wireless router settings to allow it broadcast so that ubuntu can connect to it successfully. Firefox hung up the system when I clicked eclipse download link - first system cold reset. Open jre-6u17-linux-i586.bin via Archive Manager leads to second system hang up and cold reset. It took me days to find out the right guide (Sun Java JRE) to install JRE.  unpack eclipse-cpp-galileo-SR1-linux-gtk.tar.gz and install it according to this post (Install Eclipse Galileo (3.5) on Ubuntu Jaunty (9.04)). it can't create new C++ project - no effect after hit "Next" or "Finish" button, no error message too. Some people posted a workaround - Problems with Eclipse buttons in Ubuntu 9.10.
Another GUI hang up: click on "Go" menu of "File Browser", Drop down menu of "Edit" was transparently drawn on screen and then the whole screen lock up. Although mouse is still active, but "Ctrl+Alt+Backspace" and "Ctrl+Alt+F1" do not work.

Most desktop application are developed in single language like C++, or Java, but sometimes integrating with other languages like script and XML/XSL also has prominent advantages:

• Some tasks can be easily implemented in script language, but requires much more efforts doing via C++;
• Script is easier to change and maintain to meet fast changing customer requirement;
• it takes less efforts doing representation in XSLT/HTML than traditional OS UI development.

Here is a concept design in VC++. msscript.ocx can be used to embed vbscript/jscript in VC++ application, reference: How To Call Run() Method of the Microsoft Script Control in C++. script is much more efficient than VC++ when doing OS administrative tasks via WMI. Script can convert WMI resultset into XML, and then using XSLT to transform XML into HTML and display it in a WebBrowser control. Reference: XSLT – Transformation.

Usage: It can be implemented in a desktop application to display complex content to user. WebBrowser is a powerful representation control, but it is not convenient to setup a web server to feed the content within a desktop application framework. Then a new protocol can be created to implement a rich client application that takes advantage of powerful layout capability of html without the burden of http server.

I have written a wxPython script to create a GUI prototype for review, but it is not convenient to ask user installing python. Fortunately py2exe is able to rescue. Install py2exe, create setup.py according to the Tutorial.Run the following command:

D:\test\python>c:\Python26\python.exe setup.py py2exe

got error: error: MSVCP90.dll: No such file or directory

copy C:\Program Files\Microsoft Visual Studio 9.0\vc\redist\x86\Microsoft.VC90.CRT\msvcp90.dll to D:\test\python\msvcp90.dll and run above command again, now it successfully build python script as Windows executable under D:\test\python\dist. There are a bunch of files, but it is better than installing python on user’s machine.

Downloaded MinGW-5.1.6.exe and installed to default location, then downloaded and installed gcc 4.4.0:

gcc-core-4.4.0-mingw32-bin.tar.gz
gcc-c++-4.4.0-mingw32-bin.tar.gz
gcc-core-4.4.0-mingw32-dll.tar.gz
gcc-c++-4.4.0-mingw32-dll.tar.gz

After this, g++ operator-test.cpp -o a.exe output nothing in console window, also does not product output file. “g++ –v” confirmed that I was using 4.4.0. At last, I found gcc-4.4.0-mingw32-notes.txt and followed its instruction to install other [required] components:

GMP Runtime [REQUIRED]
  gmp-4.2.4-mingw32-dll.tar.gz

libiconv Runtime [REQUIRED]
  libiconv-1.13-mingw32-dll-2.tar.gz

MPFR Runtime [REQUIRED]
  mpfr-2.4.1-mingw32-dll.tar.gz

POSIX Threads for Win32 Runtime [REQUIRED]
  pthreads-w32-2.8.0-mingw32-dll.tar.gz

Now “g++ operator-test.cpp -o a.exe ” worked as expected.

alloca function allocates memory from stack, thus is much faster than heap and is released automatically when function exit. At first look it like like declare a char array, but the difference is that you can only declare array of fixed size on stack, but you can get variable size memory (although limited by available stack size) via alloca.

#include <windows.h>
#include <iostream>
#include <iomanip>
#include <exception>
void test_stackoverflow(int size)
{
    std::cout << __FUNCTION__ << "("<<size<<")\n";
    char* ptr = static_cast<char*>(alloca(size));
    ptr[0]='a';
    std::cout << __FUNCTION__ << "()\n";
}

void test_with_std_exception()
{
    try
    {
        for(int i=102; ;i++ )
            test_stackoverflow(i*10240);
    }
    catch (std::exception& e)
    {
        std::cout << e.what()<<std::endl;
    }

}
void main(int argc, char* argv[])
{
    __try{
        for(int i=102; ;i++ )
            test_stackoverflow(i*10240);

    }
    __except (EXCEPTION_EXECUTE_HANDLER)
    {
        std::cout<<"Exception code 0x"<<std::hex<< _exception_code()<<std::endl;
    }
    if (argc>1)
        test_with_std_exception();
}
// cl -EHa overflow.cpp
// D:\test\stl>overflow.exe
//test_stackoverflow(1044480)
//  Exception code 0xc00000fd

The interesting fact is that std::queue and std::priority_queue has different interface – std::queue has front(), but std::priority_queue has top().

#include <stack>
#include <list>
#include <iostream>
#include <string>
#include <queue>

template<typename ContainerType>
void fill_container(ContainerType& cnt)
{
    cnt.push('a');
    cnt.push('0');
    cnt.push('b');
    cnt.push('c');
}

void main()
{
    typedef std::stack< char, std::list<char> > char_list_stack;
    char_list_stack mystack; fill_container(mystack);
    std::cout << "\ncontent in stack:";
    while(mystack.size())
    {
        std::cout << mystack.top() << " ";
        mystack.pop();
    }

    std::queue<char, std::list<char> > myqueue;
    fill_container(myqueue);
    std::cout << "\ncontent in queue:";
    while(myqueue.size())
    {
        std::cout << myqueue.front() << " ";
        myqueue.pop();
    }

    //std::priority_queue<char, std::deque<char> > mypqueue;
    std::priority_queue<char, std::vector<char> > mypqueue;
    fill_container(mypqueue);
    std::cout << "\ncontent in priority_queue:";
    while(mypqueue.size())
    {
        std::cout << mypqueue.top() << " ";
        mypqueue.pop();
    }

}
// cl -EHsc stack.cpp -link -verbose:lib
// content in stack:c b 0 a

A program linking with libboost_program_options-vc90-mt-gd-1_35.lib crashed at desc.add_options(), but the release version worked. At last it turned out to be due to mixed usage of debug version CRT and release version CRT – the program in trouble linked to some release version library in its debug build. The interesting fact is that VC++ 2008 does not complain during compilation, but boost.program_options raised obscure run-time error.

Here is a simple example that demonstrate usage of INNER, FULL, LEFT and RIGHT JOIN.

Create 2 tables
create table p1(pid integer, pname varchar(20));
create table p2(pid integer, ptype varchar(10));
insert some data into the tables.
insert into p1(pid, pname) values(1,'p1');
insert into p1(pid, pname) values(2, 'p2');
insert into p1(pid, pname) values(4, 'p4');
insert into p2(pid, ptype) values(1,'t1');
insert into p2(pid, ptype) values(2, 't2');
insert into p2(pid, ptype) values(3, 't3');

select * from p1;

	pid	pname
1	1	p1
2	2	p2
3	4	p4

select * from p2;

	pid	ptype
1	1	t1
2	2	t2
3	4	t4

inner join is implicit. The following two produce the same result.

select * from p1,p2 where p1.pid=p2.pid;
select * from p1 inner join p2 on p1.pid=p2.pid;

	pid	pname	pid	ptype
1	1	p1	1	t1
2	2	p2	2	t2

select * from p1 left join p2 on p1.pid=p2.pid;

	pid	pname	pid	ptype
1	1	p1	1	t1
2	2	p2	2	t2
3	4	p4

 

1;"p1";1;"t1"
2;"p2";2;"t2"
4;"p4";;""
select * from p1 right join p2 on p1.pid=p2.pid;

	pid	pname	pid	ptype
1	1	p1	1	t1
2	2	p2	2	t2
3			3	t3

select * from p1 full join p2 on p1.pid=p2.pid;

	pid	pname	pid	ptype
1	1	p1	1	t1
2	2	p2	2	t2
