VB.NET: Check To See If A Process Is Running

Question

_{Friday, February 10, 2012 8:01 PM}

Hi, I'm not sure how I would use Process.GetProcessesByName() to check if a process is running, and if it isn't start it, using VB.NET?  I know how to start a process using Process.Start().

Help?

Thanks
Aaron

What Process.GetProcessesByName() does is indeed to see if there are any processes that run with a specified name, how many etc.

I recommend using this code:

Dim p() As Process

Private Sub CheckIfRunning()
    p = Process.GetProcessesByName("processName")
    If p.Count > 0 Then
        ' Process is running
    Else
        ' Process is not running
    End If
End Sub

This code will search for the process "processName.exe", so don't manually enter ".exe" in the process name.

'I found .Count is not allowed in VS2010 use '.Length' Instead

 Private Function CheckIfRunning(sProcessName As String) As Boolean
        Dim bRet As Boolean = False
        Try
            Dim listProc() As System.Diagnostics.Process
            listProc = System.Diagnostics.Process.GetProcessesByName(sProcessName)
            If listProc.Length > 0 Then
                ' Process is running
            Else
                ' Process is not running
            End If
        Catch ex As Exception
            GL.Excep("Frm_Main_SRV.CheckIfRunning", ex)       

        End Try
        Return bRet
    End Function
