Hi,

Is it possible to capture, for example, F5 keystroke on a form even if the focus is on a textbox?

I need to capture F5 on a form independently of the control that has the focus.

Thanks!

The simple way to do this is using form.keypreview.  Setting this property true sends all key presses to the form level  handler:
Form.KeyPreview Property
http://msdn.microsoft.com/en-us/library/system.windows.forms.form.keypreview.aspx

Public Class Form1

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Me.KeyPreview = True
    End Sub
    Private Sub Form1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
        If e.KeyCode = Keys.F5 Then
            MsgBox("F5")
            'If this is false, then keypress is sent on to focus control
            e.Handled = True
        End If


    End Sub


End Class

Enable the KeyPreview property of the form and capture the keypress in the KeyDown event of the form
