![]() ![]() I didn't clear the entered text from the TextBoxes. If you enter (or scan) something in TextBox 1 and then press Enter (which usually barcode scanners automatically do after scanning a barcode), the entered/scanned Text will be displayed by DemoLabel and the input focus will automatically advance to TextBox 2, then to TextBox 3 and from there again to TextBox 1. ![]() Then replace the code of Form1 (source file "Form1.vb") with the following code. Create a new Windows-Forms-Project, add three TextBoxes to the Form via the Designer and name them BarcodeInput1, BarcodeInput2, BarcodeInput3 and add a Label named DemoLabel. Using Raw Input from C# to handle multiple keyboards If you want to take a look at that anyway, I can serve you only with an article that does this with C#: Theoretically there are ways to directly read it from the barcode-scanner so that you don't have to have that text-input-control but that would be way more advanced and, as you're saying you're a beginner to VB.NET, most probably out of your current scope. So all you would have to do is to ensure that some text-input-control has the input-focus before attempting to scan something and then process it like any text-input. ![]() It should appear as if entered it via keyboard. You can verify that by opening just any word-processing application and scanning a barcode. Meaning, they will send key-press-events to your application as if you entered something via keyboard. If you buy barcode-scanners with an USB-connector, they will have keyboard-emulation. ![]()
