This seems to be similar to your question at http://www.codeproject.com/Questions/407747/while-loop-should-run-till-i-press-another-button. Please don't ask the same multiple times.

This requires message processing inside the loop to ensure that the button's handler is called.

// 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)

Solution 1

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

C++

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

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

a minor typo: 1=1 should be 1==1 or true or just 1

Oops! :O
Fixed.

shouldn't the condition be (key != 1)?

OriginalGriff 21-Jun-12 6:50am

Depends how how he detects keypress. Since he doesn't give us any idea, it's safest just to use a generic "condition" and let him sort it out.

yeah break will do the job in any case
