Main form is a cycle, first to start a thread, when the main window to check the thread finishes make edit1. Text:='1', into the next cycle, to start a thread, dangdang main form to check the thread finishes make edit1. Text:='2',
Question 1: how to make the main form know thread finished,
2: how to make the main form of execution of the thread to perform the next cycle,

I have no idea, all the big bird to give directions, had better have an example

Delphi thread wait functions WaitForSingleObject baidu once,

CodePudding user response:

Upstairs, with the help of a wait function the thread synchronization, it is a way to write up a little bit complicated,

Another method is to keep the asynchronous state, defined in the child thread a TNotifyEvent event, the main thread with routines to monitor events, after the child thread execution activate this event, the main thread will be ready to take over control,

Top 1/f,,,,,

CodePudding user response:

Although can use semaphore to do, but the main thread has been stuck in your cycle?
The asynchronous notification form line:
1, thread finish send a message to form
2, thread class set up an event functions, the Synchronize your event function call,

CodePudding user response:

A lot of kinds of methods can achieve
Semaphore
Events
Stay to resolve
