My VB6 application needs the data directly from the Android app. That is why the server is built into the Windows VB6 application.
This server function has been working very well for my application for almost 20 years.
In the meantime I use your "AsyncStreams" without a prefix for the app. That works wonderfully ....
This also settled my request. Thanks very much.
By the way:
The VB6-application is used by rescue coordination centers.
My app sends the position and the current status from the ambulance-vehicle to the coordination center,
so they can choose the best vehicle (shortest way and free).
