用可timer控件之后程序有点卡,怎么办........

怎么用的？

对啊，要看你怎么用才卡，要是不管怎么用都卡，那就没人用了。

就是更新进程信息.....再跟新的时候有点卡.....有没有什么办法呀

你代码贴一下，让大家帮你看看。

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Me.ListView1.Items.Clear()
Dim myprecess As Process() = Process.GetProcesses
Dim thisprocess As Process
For Each thisprocess In myprecess
Dim mylistviewitem As New ListViewItem
Try
mylistviewitem.Text = thisprocess.ProcessName
mylistviewitem.SubItems.Add(thisprocess.Modules(0).FileName)
mylistviewitem.SubItems.Add(thisprocess.WorkingSet64)
mylistviewitem.SubItems.Add(thisprocess.PriorityClass)
ListView1.Items.Add(mylistviewitem)
Catch ex As Exception
End Try
Next
End Sub

进程这方面我不懂
但我确定这是你进程处理不当出现的问题
与Timer无关
另外建议你将代码改为
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Timer1.Enabled = False
Me.ListView1.Items.Clear()
Dim myprecess As Process() = Process.GetProcesses
Dim thisprocess As Process
For Each thisprocess In myprecess
Dim mylistviewitem As New ListViewItem
Try
mylistviewitem.Text = thisprocess.ProcessName
mylistviewitem.SubItems.Add(thisprocess.Modules(0).FileName)
mylistviewitem.SubItems.Add(thisprocess.WorkingSet64)
mylistviewitem.SubItems.Add(thisprocess.PriorityClass)
ListView1.Items.Add(mylistviewitem)
Catch ex As Exception
End Try
Next
Timer1.Enabled = True
End Sub

能不能说下为什么要这样子...先谢过了....

不是一定要这样做
如果你的代码没问题那就不用管它
你要知道为什么
那就把Timer的时间间隔改为1吧
呵呵

知道为什么了,不过还是很卡....
