  There seems to be a lot of activity on this forum and it has me wondering...are all these questions coming from applications that aren't going to launch until after Orcas ships OR is it "OK" to create apps today that are targetting .NET 2.0 using LINQ/DLINQ :) Is there any chance there will be a Go Live license for LINQ/DLINQ before Orcas ships Whats the latest on when Orcas is expected to ship Basically, when can we expect that we'll be able to use LINQ for real ...Show All

• SQL Server TRANSACTION

  Hi everyone, I have some doubts about Transact keywords. At the below snippet, transact is used for also error handling and as I understood that when the error occured in the transaction scope, the error is caught and then managed in a desired way. for instance, at the below snippet, the programmer catches and manages the error by first printing a message and then rooling back the execution(Stopping(ending) the execution).So can it be said that TRANSACTION is also used for ERROR HANDLING because of the above reasons BEGIN TRAN INSERT titles(title_id, title, type) VALUES (@title_id, @title, @title_type) IF (@@ERROR <> 0 ) BEGIN ...Show All

• Software Development for Windows Vista VMR9 and HD Resolution Video

  I've been having some problems with displaying DivX HD Video in my application that uses DirectX9 together with VMR9. I have been talking about problems with VMR9 before and that the only solution so far have been putting a Sleep(10) in the render loop to get rid of (I guess) blocking problems. The blocking has for me caused problems with the video not playing in full frame rate. Now, the problem is that to get DivX HD (for example) content to play smoothly I have to Sleep(25) or more, and this is a problem because I'm trying to run DirectX at 60hz or more and then everything else will not be able to play smoothly. Windows Media HD works nic ...Show All

• Visual Studio Express Editions Problems with Splash Screen and VB 2005 Express

  I create a default splash screen using Add New item | Splash Screen and then I select it in the project properties. When I run in it the VB2005 environment, the splash screen shows as expected, but then gives an error message: NullMessageException was unhandled . before running the application. Without the splash screen the application runs fine. The exception detail follows. Has anybody any idea what I am doing wrong The funny thing is if I breakpoint the code, depending on where I place the breakpoint in the Splashscreen_load , the exception does not come up. After some experimentation, the problem also may be related to my code. Th ...Show All

• Software Development for Windows Vista Authoring Workflows at runtime

  I want to implement a designer at runtime for my clients so they can create their own Workflow. As there is no out-of-the-box control to implement this I suppose I have to work with the workflowview class explained in lab 12.  I implemented this functionality but now I'm having some problems: 1)  When I try to move activities in the workflow I get an error stating "Component Serialization Service is missing".  2)  I've tried some variants of DoDragDrop from a listbox to drag a new activity to the workflow but the toolboxservice is missing and I think the workflowview also is missing the dragdropmanager at runtime.
