• arvestal Will there be a new GetOpenFileName API that wraps/calls IFileDialog?

  Similar to the way PrintDlg calls PrintDlgEx behind the scenes in 2000/XP when you don't have a hookproc, is there going to be something similar where you call legacy APIs such as GetOpenFileName and somehow it encapsulates or calls down to IFileDialog (IFileOpenDialog) From what I saw in the PDC video here: http://microsoft.sitestream.com/PDC05/DAT/DAT307.htm#nopreload=1&autostart=1 there is a ton of COM client code that need ...Show All

• Polican Custom activity based on HandleExternalEventActivity

  I would like to create a custom activity that responds to external events and then executes a sequence of activities. I initially created an activity derived from a sequence and added my HandleExternalEventActivity at the start of the sequence. However, because sequence does not implement IEventDriven I can't add it into an EventDrivenActivity sequence and therefore can't use the Listen shape to respond to my external event or something else. ...Show All

• bwvick Where is XmlnsDefinition?

  I was reading Don Box's latest MSDN article ( http://msdn.microsoft.com/msdnmag/issues/06/01/WindowsWorkflowFoundation/default.aspx ), and I noted an attribute that I can't find (meaning: I can't compile either!).
