有没有办法与PowerBuilder中的键盘按键值与Barcode Scanner条目区分开 [英] is there a way to differentiate from Barcode Scanner entry from Keyboard key pressed values in PowerBuilder

推荐答案

使用singlelineedit控件。将光标放在此处。用户可以扫描条形码或输入条目。

Use a singlelineedit control. Put the cursor there. User either scans barcode or types in entry.

扫描仪模拟键盘输入。实际上，没有任何方法可以区分两者。如果您使用OCX或COM类型控件来操作扫描仪，则可以在它们之间进行区分

The scanner simulates keyboard input. There is not really any way to differentiate between the two. If you use an OCX or COM type control to operate the scanner then you may be able to tell between them
