如果InternetExplorer正在运行检查

我画一个空白，有这个我知道是错的

Dim myProcesses As Process() = Process.GetProcessesByName("iexplore")

Dim myProcess As Process

For Each myProcess In myProcesses

   If myProcess.ProcessName.ToString IsNot Nothing Then

      MsgBox(myProcess.ProcessName.ToString)

   ElseIf myProcess.ProcessName.ToString Is "" Then

      MsgBox("closed")

   End If

Next myProcess
