• Visual Studio Performing Reports Asyncronously

  I'm using Visual Studio 2005. When I save a report with the "perform report asyncronously" enabled, it is not doing so in my application. It executes asyncronously in the Crystal Reports XI designer, but locks my app as soon as crystal is loaded  and begins executing the query in my application. I don't see any way to inherently force the crystalreportviewer control to run the query asyncronously in a .Net application in the documentation. ...Show All

• Visual Studio Team System Synchronizing Predecessor Info between VSTS and Project

  Since developers will probably not look at MS Project and will look at VSTS, we feel that predecessor information needs to be captured for Tasks, since tasks frequently have dependencies. Hence, we added a custom field in the process template to specify task predecessors. However, the predecessor information specified in VSTS does not get synchronized with MS Project. Also in VSTS, the predessor info contains VSTS-ass ...Show All
