Barcode scanner claiming problem in a multithreaded application

May 28, 2007 1 Replies

Hi,



We seem to have run into a major issue, that for the time being we are unable to solve by ourselves. The trouble is that for some reason the properties PosCommon.Claimed and PosCommon.State seem to be locked somehow. There is no timeout or exception thrown there, the application simply freezes. After several days of debugging it turned out that the line of code that hangs the application is simply reading either of these properties. Has anyone ever experienced behavior like that? There are several threads accessing these properties from time to time, but it's always thread no. 1 that freezes there, and it's always after a barcode has been scanned, when the application is supposed to be in control of the scanner already. Please help.



Thanks in advance.

This newsgroup is for discussion of the MS Retail Management System and MS Point of Sale products. You might get a better response from one of the development tool groups, but your best bet is probably the scanner manufacturer's support group.

Hope that helps at least a little...
