how add a string to focused texbox in winform c#

Question

I want to add a char to focused texbox in winform c#. how can i do that ? actually i want control e.KeyChar in myform_KeyPress event.

private void add_user_KeyPress(object sender, KeyPressEventArgs e)
    {
        if (e.KeyChar == '\r' && hidden_scan_textbox.Text != "")
        {
            shomare_shenasai_view.Text = hidden_scan_textbox.Text;
            hidden_scan_textbox.Text = "";
        }
        if (e.KeyChar != '\r')
        {
            hidden_scan_textbox.Text += e.KeyChar;
       //here i want to add e.KeyChar to focused texbox
            e.KeyChar = '\0';
        }
    }

just added the char required why do you need it to be `e.KeyChar` — V4Vendetta, Oct 04 '11 at 07:39
why not leave how is - char will be entered to focused textbox automatically by default :) — Renatas M., Oct 04 '11 at 07:48
i work with a `barcode scanner` so i need to handle it by myself — hamze, Oct 04 '11 at 07:50

myFormInstance.ActiveControl returns the current focused control in the form.
Be careful because it could (depending on how your form is built) also be another control and not a textbox.

Have also a look at here: What is the preferred way to find focused control in WinForms app?

@hamze: Sorry, no idea. We need more code to try to understand the problem, you could possibly post a new question... – digEmAll Oct 04 '11 at 08:32
