Get windows access bridge connection status Returns the current status of the connection between IA-Connect Agent and the Windows Access Bridge (WAB). If IA-Connect Agent is connected to the WAB then the relevant details are returned as outputs. Get windows access bridge info Returns informatio...
A minimum broadcast delay of one-third the average network connection travel time is appropriate. Once you exceed this limit, the additional traffic can cause more grief than benefit. Put class files into a (compressed) container for network downloading. Avoid repeatedly evaluating invariant expression...
