How to hide process by clicking button

Question

I wonder if it is possible I get the id of a program like in the example and hide it (since it is already open), taking it from the navigation bar (http://i.imgur.com/fiAQ3fJ.png), that is, when clicking the button it hides the program, but it continues running normally and hidden. I haven’t tried anything yet because I still don’t understand how to do.

Answer 1

There are several ways to do this, but here’s one of the easiest.

Above all, refer to this namespace:

Imports System.Runtime.InteropServices

Now declare that function.

<DllImport("user32.dll")> _
Private Shared Function ShowWindow(ByVal hWnd As IntPtr, ByVal nCmdShow As Integer) As Boolean
End Function

And use this method to display or hide something.

Public Sub AlterarStatus(ByVal NomeDoProcesso$, ByVal Status As Integer)
    Dim mywindow As Integer
    Dim processRunning As Process() = Process.GetProcesses()
    For Each pr As Process In processRunning
        ' Uso do ToLower() para ignorar maiúsculas de minúsculas, se não quiser isso, remova
        ' nos dois membros
        If pr.ProcessName.ToLower() = NomeDoProcesso.ToLower() Then
            mywindow = pr.MainWindowHandle.ToInt32()
            ShowWindow(mywindow , Status)
        End If
    Next
End Sub

In the argument Status, if its value is 0, the window will be occult, if it’s 1, she will be showoff.
