how to force a text box to always be in focus.
in [VB.NET]

From: AussieRules on 21 Feb 2010 20:31 Hi, I have an application that has a single text box, but many many buttons, and a few other controls (grid etc). The problem is that the application has a barcode scanner that acts like a keyboard. What I need to have is that the text box always has the focus, so at anytime the barcode scanner is used, the value is in the text box. If I push a button or slide the grid etc, the focus moves from the text box to the other control, which means when the bar code scanner scans, the value is not entered into the text box. Is there a way to have it so that the txt box always has the focus, yet the other controls still work ?

I don't understand. TextBox.Text = "whatever" works whether TextBox has the focus or not. And the assigned value is displayed whether TextBox has the focus or not. Bob

Do not consider that advice as a brute-force tip, but can't you consider this: ' Try to handle LostFocus event and re-focus before losing focus Private Sub TextBox1_LostFocus(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.LostFocus TextBox1.Focus() End Sub It may -not- be useful if your form design deals with another control pattern based on the user interaction principles.

Hi Onur, That was the one I forgot, You are right, but what is brute in the given question?
