我也有过这种情况，后来有人知道，既然在1后面肯定要执行2，那为什么不把2放到1中去调用呢，不要放在主的地方调用，这样既能保证2肯定得到1的参数，又能提高程序效率 -oceandeep(北极熊® Zzz Zzz); 2002-10-4 (#781377@0)

那样做不还是一样吗? 那为什么, 用Msgbox 以后就没问题了?! 而用Sleep 就不行了? 请教. -redmouthbird(Everything but girl); 2002-10-4 (#781406@0)

有可能是程序的并行处理，不知道1能不能在sleep15000前做完 -oceandeep(北极熊® Zzz Zzz); 2002-10-4 (#781416@0)

"sleep" stops the current execution, including the "command1". try "timer" if the delay is neccessary. -pingyangtiger(平阳虎); 2002-10-4 (#781439@0)

I got it . just coz sleep will stop all execuation , which is no good . using timer makes it better . Thanks buddy . -redmouthbird(Everything but girl); 2002-10-4 (#781492@0)

呵呵，这个代码我做过，这样，在1 做完前 cpu的占用率一直是 100%，被我的 director 看见了，惨哪 -oceandeep(北极熊® Zzz Zzz); 2002-10-4 (#781458@0)
you not kidding, are u?timer is a better solution, I would say, as someone above said,
the only different is you have to figure out a better way to detect
the finish-event of 1st command, i always worry about dead-loop
kind of things -rootbear(啤酒(^v^)); 2002-10-4 {214} (#781505@0)

其实我是想说：不能用sleep。因为主线程sleep会无法接收到第一个call完成时的消息。其实更合理的作法是在第一个call完成的消息里执行第二个call -miketany(MIKE老狼); 2002-10-4 (#781563@0)

use vb's timer, it works in thread mode. -bluebluesky(bluebluesky); 2002-10-4 (#781941@0)

请教一个问题：VB中如何把一个异步方法转为同步方法？其实这和正在讨论的问题是一样的，不能sleep，不能timer，如果用循环又会占用CPU，高手有什么办法吗？ -miketany(MIKE老狼); 2002-10-4 (#781973@0)

VB好象没办法实现VC的那种多线成，以前试验而已，即使去得线程序号也控制不了。不过大概手低，不灵 -ningxin0809(雁影行洲); 2002-10-4 (#781983@0)
你不是自己解决了嘛，互相调用 -oceandeep(北极熊® Zzz Zzz); 2002-10-4 (#781986@0)

不明白，能详细一点吗？我正要做一个function，把一个异步调用的方法包装成一个同步方法，是不容易 -miketany(MIKE老狼); 2002-10-4 (#782489@0)

偶以前做过，最近没空，天天在TTC上横贯toronto，劳命伤财，过两天再来看你们做好了没。 -henhen(哼哼~~,找工ing~~~~); 2002-10-8 (#787731@0)

1, I think you can you Semaphore, mutex this kind of API, for example, Semaphore, WaitForSingleObject works in the way u want)2, develop a dll using VC, and send a handle( for example , edit) to dll, and in the dll develop a function, using SendMessage, PostMessage, post the message to the handle's holder, in the holder's event(for example edit's onchange) deal with defferent message useful to you. -bluebluesky(bluebluesky); 2002-10-8 {278} (#787445@0)
