FormatDateTime 如何得到 英文月份的缩写?

[jaffy]

按照定义,我把月份写MMM,本指望得到英文月份的缩写,结果得到中文月份的显示,怎么才能得到英文月份?是不是要设置系统才行.

unsigned(僵哥)的代码看不懂,能说详细点吗?
====================================
不要光让给说详细解释,其实就是strftime(str表示string,f表示Format),也就是针对时间的格式化,相关的可以按一下F1得到帮助,具体的%(x)代表什么意思,在当中就有:

另外可以使用API GetDateFormat来执行转换,但是千万要记住,LanguageID不可以使用当前的,否则在非英文系统下就有可能不是你所想要的.

[BlueDeepOcean]

mmm Displays the month as an abbreviation (Jan-Dec) using the strings given by the ShortMonthNames global variable.

[BlueDeepOcean]

AnsiString as = FormatDateTime("yyyymmmdd hh:mm:ss",Now());
ShowMessage(as.SubString(5,3));

[BlueDeepOcean]

上面的5是根据字符串“yyyymmmdd hh:mm:ss”中“m”的起始位置以及个数确定的。

[i_love_pc]

是不是和安装时候的地域选择有关系,我的cb6也是这种情况,还要自己写了一个转换吗?

[BlueDeepOcean]

应该和系统的区域设置有关。

[僵哥]

#include <time.h>

struct tm *time_now;
time_t secs_now;
char str[80];

tzset();
time(&secs_now);
time_now = localtime(&secs_now);
strftime(str, 80,
"%A, %b %d 19%y",
time_now);
ShowMessage(str);

兰色的不对,
unsigned(僵哥)的代码看不懂,能说详细点吗?

其实问题不复杂,自己写一个,也没什么.准备结帖了.
