Retrieving GUID(Globally Unique IDentifier) from a device

Startbeitrag von James Covington am 08.05.2015 15:58

Dear WinDev forum,

I've been tasked with reading in information from a 3rd party device (fingerprint scanner). This device is connected to my computer via an ethernet cable.

I have created a socket to communicate with this object and am now trying to declare the fingerprint scanner as a COMObject. To do so I need to retrieve the GUID for this object, however I do not know how to retrieve the GUID for an object connected via ethernet cable. Does anyone know how to solve this problem?

I am currently using WinDev20, if you need any more information feel free to ask. Thank you in advance for your help!




Hi James,

If you can already work and talk with the scanner, why do you need any com object?

A com object is... an object declared on the PC coming from a set of DLL that should have been provided with your device as a developer kit. Once this OCX/DLL file is installed you "can" register it with regsvr32 and use the objects. Then you can make a small search in the registry to find out the class ID if you can't get it (or maybe use WDXView provided with WinDev?)

Best regards,
Alexandre Leclerc
