问题描述

大家好
在我的代码中，我正在使用一个无限循环while(1)
{
xxx;

}
但是现在当我按下一个按钮时，我需要打破这个循环吗?怎么做?请帮助我...谢谢您的宝贵意见.

Hi guys
in my code i am using one infinite loop while(1)
{
xxx;

}
But now i need to break this loop when i press one button ? how to do that? please help me in that ....Thanks for ur valuable comments

推荐答案

break语句使循环的执行立即结束:

The break statement causes execution of the loop to end immediately:

while(1==1)
   {
   xxx();
   if (condition)
      {
      break;
      }
   }

错别字:"1 = 1"，而不是"1 == 1".感谢johannesnestler！ -OriginalGriff [/edit]

[edit]Typo: "1=1" instead of "1==1". Thanks johannesnestler! - OriginalGriff[/edit]

，如果您需要压缩代码:)

if you neeed compact code :)

while(!condition)
{
   xxx();
}

在按钮的处理程序中设置condition = true

Set condition=true in button''s handler

//但是现在我需要在按下一个按钮时中断此循环

至少有两个变体:):
-循环和按键监视程序处于不同的线程中(使中断条件发生)
-循环也处理其(主)线程的消息(处理产生中断条件)

// But now i need to break this loop when i press one button

There are at least two variants :) :
- the loop and the key-watcher are in different threads (wather makes the break condition)
- the loop does process messages for its (main) thread as well (processing makes the break condition)
