VB.NET使用ProcessName

Question

我创建了一个程序，其函数按进程名称读取应用程序......

当运行Calc.exe时，Label31从CLOSE更改为OPEN，但是当我关闭Calc.exe Label31时，不希望从OPEN更改回CLOSE ...

我的代码

Private Sub Timer2_Tick(sender As Object, e As EventArgs) Handles Timer2.Tick
Dim myProcess() As Process = System.Diagnostics.Process.GetProcessesByName("calc")
    For Each Read As Process In myProcess
        Label31.Text = "OPEN"
    Next
End Sub

当封闭的label31从OPEN变为CLOSE时，任何人都可以帮助我如何计算？

如果您投票，请执行以下操作：

Private Sub Timer2_Tick(sender As Object, e As EventArgs) Handles Timer2.Tick
    Dim myProcess() As Process = System.Diagnostics.Process.GetProcessesByName("calc")
    Label31.Text = If(myProcess.Length > 0, "OPEN", "CLOSED")
End Sub
