• Software Development for Windows Vista Getting information about a workflow instance

  I am building an Workflow-based application that will contain a "Task List" to inform users when a workflow instance is waiting for their input. I would like to populate this Task List by examining the loaded workflows and determining which are waiting for input from the current user (based upon Role membership).

• Community Chat Some neat things about Vista.

    I'm not using the Vista Start menu. I am using someone elses and it didn't come with Help. (I think I know why) Vista's new help engine is called Helppane.exe and simply starting it up doesn't bring up help. In looking into this I discovered that the taskmanager displays somethings that it didn't used to. For example it display command lines for processes that just started up. I start the normal Vista Start button and select Help and when it came up I noticced that the command line was Helppane.exe -embedding All I had to do then was a add that to the link and I now have help. Does anyone else have any interesting Vista tips. I think we'll stat to see a lot more interest this week. Well I take that back in th ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. 3D Actors and animation for games

  Hello I am currently taking part in the XNA GSE beta, but I approach this from the content production side with focus primarily on 3D character motion and facial animation. My expertise is not coding, but intrigued by the press blitz put on by MS I took bait. Here's what I'm thinking. I would like to test and work with those here to collaborate on a project. I can provide some characters and animation in FBX format or X format, which can convert to SWM if necessary. If anyone is working on a FPS or action/adventure, or any game for that matter that would need 3D characters and facial animation please contact me. I can produce prototypes on-the-fly of any basic human in general clothing or more complex needs based on the project. Ultima ...Show All
