• Visual Studio 2008 (Pre-release) Syncrhonizing an 'Order'

  Hi, I'm not sure if Synchronization Services can help me but I hope so. Suppose I create a new an Order in the client side. It has header and lines. When I synchronize with the server I need two things: - I need to be sure the header and the lines are inserted in the same transaction. - I need to validate the Order. Even if it was valid in the client side, I need to be sure it's valid before inserting it in the main database. Can this be done with Synchronization Services Thanks Thanks Rafik, Next question. Suppose I have an 'Orders' class, with header and lines, and I want to use that class to persist the changes to the database. I want to use the synchronization framework to know ...Show All

• Visual C++ Declaring a delegate

  How can I declare (not define) a delegate as if I declare a class Semantics, really. What you've done isn't defining a delegate, but rather declaring it.

  I am confused the first parameter of AddSourceFilter. Why is there a file to load and where is it If I want to capture video and render it to a monitor in realtime, is there stream only It seems there is not a file to be added. IGraphBuilder::AddSourceFilter docs say: "The AddSourceFilter method adds a source filter for a specified file to the filter graph." So it is for loading files.

• SQL Server Create Directory with a File System Task

  Hi! I'm having a bit of a problem implementing a File System Task to Create a directory and would appreciate some help if possible.

• Visual C++ VC++ 2005 redistributable (vcredist_x86.exe etc.)

  Hi there, I noticed that the Beta 2 redistributable is hosted on the Microsoft download library, but the final ones seems not to be. Will it be hosted on microsoft.com (or is it already somewhere ). Also, it has been reported to me that on Windows 2000 the (RTM) redistributal gives an unuseful error message if Windows Installer 3.1 is not installed. The message is error 1723. "A DLL required for this install to complete could not be run." . It would be a lot more helpful to my users if this was a more informative error message - the solution of installing Windows Installer 3.1 was only found by trial and error. Thanks. I agree, in a perfect world Microsoft would revisit this and eliminate the possibl ...Show All

• Visual Studio 2008 (Pre-release) Overlapping elements over a FlowDocument

  Hi, I have a FlowDocument with sections, paragraphs, lines, etc. My target is (for example) to draw two lines in order to create a cross over the page (from angle to angle) so that the lines overlaps the entire page content. Another example is to overlap a big text like "Confidential" over (or behind) the content page. I tired using floaters but they need to be inside an inline, so they take space and modify the flow of the page. I want to overlap those elements without changing the normal flow instead. Thanks, Raffaele Hi Lester, thanks for your answer but Adorners need to be created programmatically (afaik) so I cannot describe the line cross or the "confidential" directly in xaml. I need to create a ...Show All

• Community Chat Zune Subscription

  I've been scrounging around online and thought I might be able to get a definitive answer here. Currently, I have Napster-to-go with my Dell DJ. The DJ is on it's way out the door, and I'm looking at getting a Zune. Will this Zune subscription thing for 15 bucks a month allow me to transfer music to the player itself, or is it simply to let you listen to music on your computer In other words, will there be something like napster-to-go that works with the Zune TIA! I'm really confused about the Zune Terms of Service, specifically section 14, Content Usage Rules. The way it reads, it sounds like I will lose access to any content purchased during my subscription if I end my subscription. For example, I buy ...Show All

Using local reports in winforms app. I have a main form and then another form specifically for reports that contains only a Reportviewer control.
