How to Focus a TextBox VB.Net

I have a text box in my form. When clicking the tray icon the form is shown and on form load I have written the code to focus on the text box. But it's not pointing the text box. Let I have 2 forms formB and formC I am calling formC from formB so that I doesn't getting the focus. how to give focus to the second form? I have find the solution to this problem . we have to overwrite the show method. Let's say formA and formB. Then FormB is in focus now. 

Private Sub FormB_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    Me.Timer1.Enabled = True
    Me.Timer1.Interval = 2000
End Sub`

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
    Timer1.Enabled = False
    Dim frmquickListPHD1 As New FormC()
    frmquickListPHD1.Show(CallingForm, CallingControl, Me)
End Sub

   Overloads Sub Show(ByVal f1 As Form, ByVal c As Control, ByVal f2 As Form)
    callingform = f1
    MenuForm = f2
    callingcontrol = c
    Show()
End Sub
Private Sub FormC_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    Me.TextBox1.Focus()
End Sub`

use the ActiveControl property of your form in the load event of the form:

Me.ActiveControl = Textbox1

Alternatively, if you're showing an instance of FormB from FormA on some event then you could use the following code in FormA:

Dim FormB1 as new FormB
FormB1.show()
FormB1.ActiveControl = FormB1.Textbox1

Don't use focus, from msdn (http://msdn.microsoft.com/en-us/library/system.windows.forms.control.focus.aspx):

Focus is a low-level method intended primarily for custom control authors. Instead, application programmers should use the Select method or the ActiveControl property for child controls, or the Activate method for forms.

The issue may be that the form does not have focus when you open it from the system tray?

Try something like:

frmTest.Show
frmTest.Select

The in your Form_Activated event of frmTest

textbox1.Select
