USB BarScanner RawInput without Gui

Recommended Posts


I'm trying to understand the RawInput UDF but I'm not very advanced with DllCalls and Struc.

All the examples I found, which actually works with my bar scanner are using a GUI and Return 'GUI_RUNDEFMSG'.

But I don't want to do that, what I want to do is be able to read the rawinput data from the USB barscanner without any GUI and base on what I read trigger some actions/functions.

Anybody can provide a simple sample code?

      This UDF allows to set an events handler for Mouse device.
      The beginning...
      I searched for a way to disable the Mouse Primary click, and be able to call some function when the click event is received...
      Big thanks to amel27 for this one, i only organized the whole stuff to UDF style.

      Recently a user asked given two keyboards how to determine which keyboard was pressed this is the start of such functionality
