ManualResetEvent alternative in Java

can not jdk uninstall Error 1723

for uninstall jdk

if you can not uninstall jdk update 16
1) install jdk update 15
2) create folder jdk1.6.0_16 and copy files from jdk1.6.0_15 to jdk1.6.0_16
in C:\Program Files (x86)\Java
3) install jdk 16 , it will remove old version of jdk 16

How to do dynamic loops For

Problem is
How to realize dynamic for-loops in source code

Visual Sudio solution you can dowload here

like this

for(int i = 0 ; i < 10 ; i++)
  for(int j = 0 ; j < 4 ; j++)
   for(int k = 0 ; k< 9 ; k++)
     ...........................
        ........................
          Console.Write( i , j , k ....)

* This source code was highlighted with Source Code Highlighter.

for this task i create class ManyFor

it simple to use (see ManyForTest)
ManyFor class generate all combination of i , j , k , ....

Example:

      int[] mm = new int[] { 3, 2, 4 };

      ManyFor mf = new ManyFor(mm);

      for (int s = 0; s < mf.Count(); s++)
      {
        ReadOnlyCollection<int> r = mf.Get(s);

        int i = r[0], j = r[1], k = r[2];

        Console.WriteLine(i + " " + j + " " + k);
      }

Math parse expressions. c# java

PS math parser .net , Math expression parser, Mathematical Expression Parser , .Net Math Parser, mathematical expression parsing

easy to use use and modify ( add functions , add your objects and so on)

If you can parse math expressions like this

5*4+3*7+8/3+abs(10-15 ) + max( 100 , 11, 1 ) + min ( 4 , 2) + X +X*X + ......

Visual studio solution you can download here http://stream.ifolder.ru/12757267
http://rapidshare.com/files/276525245/MathParse__1_.zip





1) generate list of tokens , where one token is object
2) create tree of tokens
3) create IValue object of math expression

1)
token is

  public class Token
  {
    public List<Token> tokens;
    public IValue ivalue;

    public string type;   
    public string value;  
    public string parseInfo;

Compile memcached windows (Cygwin) (all tests passed !!!)

Memcached win32 32 bit you can download from here
all tests from folder "t" passed ,

but in libevent test

Simple DNS resolve: [Timed out] FAILED
IPv6 DNS resolve: [Timed out] SKIPPED
Simple reverse DNS resolve: [Timed out] FAILED

//==============================================================
if you want install youself

1) you need
http://win6.jp/Cygwin/cygwin-1.5.25-15-ipv6-0.22.zip
http://monkey.org/~provos/libevent-1.4.9-stable.tar.gz
http://www.danga.com/memcached/dist/memcached-1.2.6.tar.gz

2) unpack cygwin-1.5.25-15-ipv6-0.22.zip - into you cygwin folder
about this files read site http://win6.jp/Cygwin/

3) in libevent http.c file add line ---> #define EAI_SYSTEM 11
now install libevent
./configure
make
make install

4) in memcached.c file add 3 lines --->

#define AI_PASSIVE 0x0020

#define AI_ADDRCONFIG 0x0001

#define EAI_SYSTEM 11

now install memcached

5) i run all tests and all tests passed !!!!!!! (unlike mamcached compile in visual studio )

Compile memcached-1.2.6 under windows Visual Studio 2005 (use Jellycan Code )

1) i use files from http://code.jellycan.com/memcached/
get memcached-1.2.6-win32-bin.zip
libevent
2) need folder memcached and libevent put together

/src/libevent
/src/memcached

and event-config.h (from \libevent\WIN32-Code ) copy to "/src/libevent"
and in memcached properties VS2005 add
Additional Include Directiories - ../../libevent/
3) now you can compile memcached ,
4) all files here , VS2005 solution
http://stream.ifolder.ru/10219356

5) exe here - http://stream.ifolder.ru/10219544

TESTS (Cygwin)
1) if you have cygwin
you can test memcached , in folder "t" you have test perl files ,
for run test , open cygwin shell

form cygwin_lib_perl.rar - unpack to cygwin folder
OR install cygwin_Cache-Memcached-1.24.tar.gz and cygwin_String-CRC32-1.4.tar.gz

2)you can run test separately test like this
>perl udp.t
and you can run run_all_tests.bat and view *.txt fils
you will see like this


3) you see that tests

stats.t
incrdecr.t
64bit.t

FILED !!! i dont know why !!!
who have linux or unix , all tests passed ???

Compile libevent-1.4.9-stable under windows Visual Studio 2005

Compile libevent-1.4.9-stable under windows Visual Studio 2005

0) if you want get now solution go 7) ( and 6))
1) I take file "event-config.h" from http://code.jellycan.com/memcached/ - libevent-1.4.4-stable-win32.zip
2) copy event-config.h to ---> ...\libevent-1.4.9-stable\WIN32-Code
delete event-config.h from ---> ...\libevent-1.4.9-stable
3) now you can open ...\libevent-1.4.9-stable\WIN32-Prj\libevent.sln
and compile it
4) i write

#define exit(i) printf(" _____exit(%d) - hidden _____\n", i);

in file regress_dns.c
and write in function "main" before "return (0)"

printf("End tests ...");
while(1);

5) now you run regress project and will see like this



6)!!! you can see

Simple DNS resolve: [Timed out] FAILED

i dont know why this error !!!
7) now here the all source and solution for Visual Studio 2005
open ...\libevent-1.4.9-stable\WIN32-Prj\libevent.sln

http://stream.ifolder.ru/10217927

compile and run regress test
8) libevent64.lib - libevent for 64 bit windows
