Hello, I am learning VB.net and would like help. I’m doing a little program to check if a process is open and if it’s not, open it.

I’ve come this far: 

    Private Sub CheckIfRunning()
    p = Process.GetProcessesByName(TextBox1.Text)
    If p.Length < 1 Then
        Process.Start(TextBox1.Text)
    End If
End Sub

The problem is that it keeps opening the process several times, even if it is already open. Someone can help me with this?

vb.net process

  • What is the content of TextBox1.Text?

Hello, Sergio!

Try it this way. Note: I don’t know how you are passing the name of the process, but Getprocessesbyname has to receive the name of the process without extension already Process.Start() needs the extension.

Private Sub CheckIfRunning()

    Dim p As Process = System.Diagnostics.Process.GetProcessesByName(Path.GetFileNameWithoutExtension(TextBox1.Text))

    If p.Length < 1 Then
        Process.Start(TextBox1.Text)
    End If
End Sub
