循环内存消耗？ [英] Do loop memory consumption?
问题描述
下面的Timer循环消耗了我的开发PC的所有可用CPU时间。
我希望能够将CPU时间的使用限制在最小值，因为
it实际上并没有做任何事情，只是倒数剩下的时间。
非常感谢任何帮助。
比尔
昏暗t作为整数= 0
Dim Start，Finish，TotalTime As Double
''Start = Microsoft.VisualBasic.DateAndTime.Timer
完成=开始+ mSeconds''将结束时间设置为mseconds持续时间。
t + = 1
lblInfo.Text =" test timer - > " &安培; t $ / $
lblInfo.Refresh（）
''等待5秒后再进行其他处理。
循环
The Timer loop below consumes all available CPU time from my development PC.
I would like to be able to restrict its use of CPU time to minimum since
it''s not actually doing anything but counting down the time left.
Any help is greatly appreciated.

Dim t As Integer = 0
Dim Start, Finish, TotalTime As Double
''Start = Microsoft.VisualBasic.DateAndTime.Timer
Finish = Start + mSeconds '' Set end time for mseconds duration.
Do While Microsoft.VisualBasic.DateAndTime.Timer < Finish
t += 1
lblInfo.Text = "test timer -> " & t
lblInfo.Refresh()
'' Do other processing while waiting for 5mseconds to elapse.
Loop

修复此问题的一种方法是在你的lblInfo.Refresh（）之后插入System.Thread.Sleep（100）
。

One way to fix this would be to insert System.Thread.Sleep (100) right
after your lblInfo.Refresh ().

比尔，
您是否考虑过使用System.Windows.Forms.Timer？

请回复到新闻组。
Bill,
Have you considered using System.Windows.Forms.Timer instead?

Tom;
这似乎解决了我的问题。我发出1000毫秒的CPU时间和b $ b b显着下降。使用的内存大概还差不多，但是我可以支付
！
另外一个问题，请：
我需要在用户中断循环按下STOP按钮。问题
btnStop（在同一表格上）在循环期间无法访问。
有没有办法在do循环期间检查按钮是否被按下
例程？
再次感谢;

Tom;
That seemed to solve my problem. I assinged 1000 miliseconds and CPU time
went down significantly. memory used still about the same, but that I can
afford!
Another question, please:
I need to interrupt the loop when user presses the STOP button. The problem
that btnStop(on the same form) is not accessible during the loop.
Is there a way to check if the button was pressed during the do loop
routine?
Thanks again;
Bill
