另外給初接觸 objective-c 的介紹:

obj->method(argv);

[obj method: argv];

@implementation HelloController
- (IBAction)sayHello:(id)sender {
  [destinationTextField setStringValue:[sourceTextField stringValue]];
}
@end

(id)sender 是一個可以選擇性的用法,若您有需要取得發出 IBAction的元件時,可以用這個 sender變數來取得.但記得可能需要 cast一下.

UIButton *senderButton=(UIbutton*) sender;[senderButton setHidden: YES];

這樣就會把該button隱藏起來.

[2010/7/9 下午 04:48:25] Rimmon 2.0: jason 有 mac os 的 sftp GUI 的 tools 嗎?

[2010/7/9 下午 04:48:40] Rimmon 2.0: 想要用 tools 傳 code 比較方便

[2010/7/9 下午 04:51:05] _RTN Jason Chen: http://www.versiontracker.com/dyn/moreinfo/macosx/15693

[2010/7/9 下午 04:51:08] _RTN Jason Chen: Fugu

[2010/7/9 下午 04:51:35] _RTN Jason Chen: www.versiontracker.com 有非常多的 OSX 軟體可下載

[2010/7/9 下午 04:53:59] _RTN Jason Chen: 還有 Microsoft Remote Desktop Connection 可遠端遙控 Windows

[2010/7/9 下午 04:55:13] _RTN Jason Chen: smb://172.30.0.29/Install   這樣 OSX 才看得懂網路分享目錄

[2010/7/9 下午 05:00:10] _RTN Jason Chen: Finder, 用 apple鍵 + K 再輸入 cifs://172.30.0.19/Install 即可連 server shared

要研究這麼深?! 沒辦法, 最近遇到奇怪問題非得啟用 Promiscuous Mode 來看看發生啥事了.

上週聽了 ora 公司的產品說明, 覺得不錯.

它是 tracking system 產品, 可是更 friendly / 非侵入式的作法, 它利用 switch 或 SLB設備的 mirror port 把流經的 traffic 導進這個 program , 由這個 program 來進行 traffic 分析.

架構簡圖:

若要自行作的話可能會需要看懂這個

不過 , 這邊有指定 eth0 , 若 server 有很多 interface 的話就要注意一下了.

#include <stdio.h>
#include <sys/ioctl.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <net/if.h>

int main( int argc, char *argv[] )
{
	int s;
	struct ifreq buffer;

	s = socket(PF_INET, SOCK_DGRAM, 0);

	memset(&buffer, 0x00, sizeof(buffer));

	strcpy(buffer.ifr_name, "eth0");

	ioctl(s, SIOCGIFHWADDR, &buffer);

	close(s);

	for( s = 0; s < 6; s++ )
	{
		printf("%.2X ", (unsigned char)buffer.ifr_hwaddr.sa_data[s]);
	}

	printf("\n");

	return 0;

"C 語言" … ㄏㄏ.. 這麼古老且重要的語言,從 1972年開始到現在至少超過30年! 學會 pointer 後 C 就算是懂 90% 了

Expat is an XML parser library written in C. It is a stream-oriented parser in which an application registers handlers for things the parser might find in the XML document (like start tags). An introductory article on using Expat is available on xml.com.

Jack 大大寫好了這段 code , 很好用, 就貼在這兒了, 下次可以直接剪下跟貼上

重點有兩個:

1. From encoding 是 CP950

2. libiconv 不要用 libc 的, 因為缺一個 function : iconvctl

int fnConvert(const char *from, const char *to, char* save, int savelen, char *src, int srclen)
{
    iconv_t cd;
    char   *inbuf = src;
    char *outbuf = save;
    size_t outbufsize = savelen;
    int status = 0;
    size_t  savesize = 0;
    size_t inbufsize = srclen+1;
    char* inptr = inbuf;
    size_t      insize = inbufsize;
    char* outptr = outbuf;
    size_t outsize = outbufsize;

    if ( ( cd = iconv_open(to, from) ) == (iconv_t)-1 )
    {
        status = -1;
        goto done;
    }

    iconv(cd,NULL,NULL,NULL,NULL);
    if (inbufsize == 0)
    {
        status = -1;
        goto done;
    }
    while (insize > 0)
    {
        size_t res = iconv(cd, &inptr,&insize,&outptr,&outsize);
        if (outptr != outbuf)
        {
            int saved_errno = errno;
            int outsize = outptr - outbuf;
            strncpy(save+savesize, outbuf, outsize);
            errno = saved_errno;
        }
        if (res == (size_t)(-1))
        {
            if (errno == EILSEQ)
            {
                int one = 1;
                iconvctl(cd,ICONV_SET_DISCARD_ILSEQ,&one);
                status = -3;
            }
            else if (errno == EINVAL)
            {
                if (inbufsize == 0)
                {
                    status = -4;
                    goto done;
                }
                else
                {
                    break;
                }
            }
            else if (errno == E2BIG)
            {
                status = -5;
                goto done;
            }
            else
            {
                status = -6;
                goto done;
            }
        }
    }
    status = strlen(save);
done:
    iconv_close(cd);
    return status;
}

EXAMPLE:
int fnB2U( unsigned char *str )
{
    int srclen, destlen, status;
    unsigned char tmp[2048];

    status = -1;
    if ( ( srclen = strlen( str ) ) == 0 )
        return status;
    destlen  = sizeof( unsigned char ) * ( srclen * 2 ) + 1;
    tmp[0] = '';
    if ( ( status = fnConvert ( "CP950", "UTF-8", tmp, destlen, str, srclen) ) > 0 )
        strcpy( str, tmp);
    else
        printf( "status = %dn");
    return( status);
}
