Hi,
I have a program need to check the value of a application available, and then decide whether to execute codes followed.
In order to achieve this purpose, I use DO WHILE loop to judge the value, if the value meet the condition clause, program will exit the loop. But this DO WHILE loop consumes too much CPU resource.
Now my question is whether a possible way to pause a process for a given time such as one minute?
Anyone can give me some guide on this issue? Thanks
For better understanding the scenario, please refer to following codes.
Public Function DataAccessBegin () As Boolean
Try
Dim StartTime As DateTime
StartTime = Now
Do While Application("Ac tiveConnections ") + 1 > Application("Pe rmitConnections ")
'If StartTime.AddMi nutes(1) < Now Then
Me.LblMessage1. Text = "Two当前数 库访问用 太多,请 后再使用 报表!"
Me.LblMessage1. CssClass = "ERROR"
Return False
'End If
Loop
Application("Ac tiveConnections ") = Application("Ac tiveConnections ") + mDataRow(0).Ite m("FORBIDCONN ")
If Application("Ac tiveConnections ") > Application("Pe akConnections") Then Application("Pe akConnections") = Application("Ac tiveConnections ")
End If
Finally
End Try
Return True
End Function

To pause a process, you can use System.Threadin g.Thread.Sleep( x) where x is
the number of milisecond during which you want you process to be suspended.
However, in your particular scenario, i would simply use a Timer (the one in
System.Windows. Form that you can also find in the toolbox of the Window Form
designer) instead of looping and sleeping. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

When will .NET have a low-pause-time garbage collector
A low-pause-time garbage collector would greatly improve .NET's ability to serve as a platform for soft real-time systems. It doesn't have to be perfect. For example, I'd be happy with something where there was at most one pause per second, each pause was less than .2 seconds, and half the process's memory was inaccessible to the application due to garbage collection management

But I have no clue how to pause/suspend the process. As far as I can
see the Process class doesn't offer anything for this. So it's probably
the thread the process is running on that should be suspended or put to
