Hi,
I am using your C# SDK to create a project which uses Zebra D3678 HP barcode scanner to capture barcode and images. Then I exported the C# project as a .dll file and imported the dll file in my python backend code. When I ran the python code. I got the following error,
"Unable to cast COM object of type 'System.__ComObject' to interface type 'CoreScanner.ICoreScanner'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{2105896C-2B38-4031-BD0B-7A9C4A39FB93}' failed due to the following error: Object is not connected to server (0x800401FD (CO_E_OBJNOTCONNECTED))." after couple of minutes.
The C# is used to capture and send both barcode data and image data (as string) to my python backend.
The same project was working fine when I used socket connection to communicate between python and C# codes.
But I am required to remove the socket connection dependency.
Please help me to solve this issue.
Thanks in advance.
