• rob warning Waithandles and Workflow Instances

  Hi, I have a unique problem and I was hoping some one would shed some light on it. I am using the regular mechanism of starting workflow instances but not before starting an asynchronous thread to listen to incoming messges from MSMQ. Everytime, I receive a message new instance of a workflow is started to deal with that message. All of these instances are created by the second (MSMQ listener) thread and not by the main host application thread. I observed that the WokflowCompleted event (registered in the host application thread) get invoked every time the WF finishes but the waithandle.Waitone() in the end of the host application code does not get invoked. I am afraid that there might be memory leakage somewhere. ...Show All

• Paul Baudouin Support for Streaming Servers ?

  I am currently trying to find out if support for any streaming architecture has been implemented in the FEB2007 release; ideally the Windows Media Server WMS architecture. I would like to be able to access streaming content under any of streaming protocols ideally rtsp:// or mms://. Our architecture is setup on WMS and I am typically working with 45-90 minute recordings. Due to the limited support for WMP on Mac OS X as well as compatibility issues with the latest Intel based macs, I am very eager to be able to replace the embeded WMP with a WPF/E based player, however I need the ability to seek to random points in a file. Also in looking at the docs, WPF/E is said to support WM9, I was wondering if it will be suporting all WM9 codecs ( ...Show All
