GUI主线程waitforsingleobject的问题？

[rotus]

在主线程中用waitforsingleobject，等待子线程结束，为何子线程得不到响应，程序阻塞了。
怎么解决啊。子线程中只是完成一些计算啊

主线程中用WaitForSingleObject会阻塞整个进程的，界面会失去响应
发送消息好了

[rotus]

我查过一些资料，是这么说啊。子线程结束＋发送消息＋主线程响应，试下先。。。。

This function returns when the specified object is in the signaled state or when the time-out interval elapses.

DWORD WaitForSingleObject(
HANDLE hHandle,
DWORD dwMilliseconds );

同意oyljerry.
主线程会处于等待状态等待WaitForSingleObject的对象激发.

[lianglp]

MsgWaitForSingleObject()试一下。

[rotus]

MsgWaitForSingleObject也试过，没成功，哈哈。

在主线程用WaitForSingleObject会停止消息循环，应该用MsgWaitForMultipleObject();
参考以下代码。主要思想是在保持消息循环的同时等待事件发生。
int MessageLoop (
HANDLE* lphObjects, // handles that need to be waited on
int cObjects // number of handles to wait on
)
{
// The message loop lasts until we get a WM_QUIT message,
// upon which we shall return from the function.
while (TRUE)
{
// block-local variable
DWORD result ;
MSG msg ;

// Read all of the messages in this next loop,
// removing each message as we read it.
while (PeekMessage(&msg, NULL, 0, 0, PM_REMOVE))
{
// If it's a quit message, we're out of here.
if (msg.message == WM_QUIT)
return 1;
// Otherwise, dispatch the message.
DispatchMessage(&msg);
} // End of PeekMessage while loop.

// Wait for any message sent or posted to this queue
// or for one of the passed handles be set to signaled.
result = MsgWaitForMultipleObjects(cObjects, lphObjects,
FALSE, INFINITE, QS_ALLINPUT);

// The result tells us the type of event we have.
if (result == (WAIT_OBJECT_0 + cObjects))
{
// New messages have arrived.
// Continue to the top of the always while loop to
// dispatch them and resume waiting.
continue;
}
else
{
// One of the handles became signaled.
DoStuff (result - WAIT_OBJECT_0) ;
} // End of else clause.
} // End of the always while loop.
} // End of function.
