Other apps (the barcodescanner) does not have the rights to change values in your app.

If you got the barcode sended to the edittext it is up to YOU to clear the edit to get the next barcode.

if u have a Barcode reader as keyboard simulation (ex via Bluetooth connected), normal it send a line break char (return)
so u need process this text after the device simulate the enter key
and then set the text property to empty string.

Hello
what I use to know if there is any value in the EditText is:

B4X:

Sub TxtBarCode_FocusChanged (HasFocus As Boolean)
    If TxtBarCode.Text.Length>=1 Then
        SearchPCod(TxtBarCode.Text)
    End If
End Sub

To clean the EditText in the SearchPCod function if it does not find the product is:

B4X:

ToastMessageShow("Product "&TxtBarCode.Text&" Does not exist",True)
TxtBarCode.Text =""
TxtBarCode.RequestFocus

I use a barcode reader connected by Bluetooth
