前两天看了Delphi版面精华区中的“进程死亡的自动复活“一文，觉得作者的思路很不错，利用api来监视进程的活动，当被销毁时就自动再创建进程。仔细推敲之后，发觉其实用vb也是可以做到的。于是花了半天的时间写了以下的程序，实现了使用WaitForSingleObjectAPI来监视被创建的进程的活动，一旦返回除time out 之外的消息就自动创建新的进程。以下为其实现代码。在win2000 server + vb 6.0下通过。
SHOW FULL COLUMNS FROM `jrk_downrecords` [ RunTime:0.001296s ]
SELECT `a`.`aid`,`a`.`title`,`a`.`create_time`,`m`.`username` FROM `jrk_downrecords` `a` INNER JOIN `jrk_member` `m` ON `a`.`uid`=`m`.`id` WHERE `a`.`status` = 1 GROUP BY `a`.`aid` ORDER BY `a`.`create_time` DESC LIMIT 10 [ RunTime:0.091543s ]
SHOW FULL COLUMNS FROM `jrk_tagrecords` [ RunTime:0.001154s ]
SELECT * FROM `jrk_tagrecords` WHERE `status` = 1 ORDER BY `num` DESC LIMIT 20 [ RunTime:0.001934s ]
SHOW FULL COLUMNS FROM `jrk_member` [ RunTime:0.001204s ]
SELECT `id`,`username`,`userhead`,`usertime` FROM `jrk_member` WHERE `status` = 1 ORDER BY `usertime` DESC LIMIT 10 [ RunTime:0.003633s ]
SHOW FULL COLUMNS FROM `jrk_searchrecords` [ RunTime:0.000977s ]

UPDATE `jrk_articles` SET `hits` = 1 WHERE `id` = 278455 [ RunTime:0.001367s ]
