It seems the problem is worse than I initially thought. This requirement is not specified anywhere in the SDK documentation that I can see. So, simply extending a JFrame and starting the reader capture on a separate thread seems to be sufficient.
Strange as it may seem, it only works in the context of a Java GUI application. I finally managed to get an example working. This is taken from the sample application as well. The last two parameters, the two ints, passed to the Capture method are the resolution and the timeout respectively passing -1 for the timeout blocks indefinitely. The following call just hangs and never returns.Ĭr = r.Capture(_19794_4_2005, _PROC_DEFAULT, 500, -1) ReaderCollection rc = UareUGlobal.GetReaderCollection() That is about the only way I can get it to return. Unplugging the device causes the call to fail with an exception. The only difference I can see between my sample and the SDK sample app is that the latter is a graphical application.
