如何调试超出初始断点的子进程(How to debug a child process beyond the initial breakpoint)

 我的应用程序有一个启动b.exe并与之通信的a.exe。 顺序是： 
 
 
 
 a.exe启动b.exe，并等待来自b.exe的事件，并且超时时间为10秒 
 
 
 b.exe启动，注册为COM服务器，并发信号通知事件 
 
 
 a.exe在COM接口中调用一个方法 
 
 
 调用b.exe接口方法。 <<<<<我想在这里打破 
 
 
 我想在b.exe中调用接口方法。 目前，我这样做： 
 
 
 
 在windbg下运行a.exe 
 
 
 输入.childdbg 1 
 
 
 等到b.exe启动，并且其初始断点中断。 
 
 
 在b.exe中设置另一个断点并继续。 我必须在10秒内完成 ，否则a.exe将超时并杀死b.exe。 
 
 
 我设法做到了，但10秒的超时有时会过去。 有没有更好的方法来做到这一点？ 

My app has a.exe which launches b.exe and communicates with it. The sequence is:
 
 
 
a.exe launches b.exe, and waits on an event from b.exe with a 10-second timeout
 
 
b.exe starts, registers as a COM server, and signals the event
 
 
a.exe calls a method in the COM interface
 
 
b.exe interface method is called. <<<<< I want to break here
 
 
I want to break in b.exe interface method call. Currently, I do it like this:
 
 
 
Run a.exe under windbg
 
 
Enter .childdbg 1
 
 
Wait until b.exe starts, and its initial breakpoint breaks.
 
 
Set another breakpoint in b.exe and continue. I must do it within 10 seconds, otherwise a.exe will timeout and kill b.exe.
 
 
I managed to do it, but the 10-second timeout sometimes passes. Is there a better way to do it?
