I have small app in C# : WinForm with comboBox, texBox and listBox
1.I choose number from comboBox e.g. G00K
2.next I read barcode via USB device to texBox e.g. G00K 2C0109 140314A 281 133
3.after reading the number is writting to listBox.
Working well.
Now I want to verify number before writtng to listBox. First four digits from reading barcode must be same like number I choosed in ComboBox.
Thank for reply
