• Visual Studio 2008 (Pre-release) databinding bug, or am i just expecting too much? - master/detail with a combobox in the detail

  Hi, I think i may have run into a bug, maybe you'll say it's not a bug but it's not how i would have expected the framework to handle this particular case anyway... ....I'm running Vista with the feb CTP I'm setting the windows datacontext equal to an instance of a class that inherits from DependencyObject (trying to embrace the new way of handling changes in the UI / class). Then i have a listbox with it's itemssource property bound to a DependencyProperty called "Selected". I also then have a grid with it's data context set to the same path=Selected so that it shows the detail of the item selected in the listbox. This all works fi ...Show All

• Software Development for Windows Vista Activity Property values not available at runtime

  I am currently experimenting with a custom activity. We have a number of business rule objects which implement various, relatively complex data validation rules. The custom activity allows these business rule objects to be assigned to the activity and for parameters to be assigned as part of a workflow that links together a number of these business rule classes into a sequential [potentially brancing] workflow. So I basically have: BRActivity RuleClassReference ClassID ClassName ParameterCollection Parameter1 Name Value Parameter2 Name Value I've integrated these activities into an end-user design ...Show All

• SQL Server SQL 2005 Sept. CTP: Installation error related with encryption

  Hi everyone, I've been trying to get SQL Server 2005 Sept. CTP installed for a few days and always end up with the same installation error:  "Setup could not connect to the database service for server configuration. The error was: [Microsoft][SQL Native Client]Encryption not supported on the client. Refer to server error logs and setup logs for more information.

• Visual Basic Querying Active Directory to check if a Username exists

  Hi Everyone, We are doing a lot of work on our Storage server at the moment, and one thing is tidying up users folders.

• Visual C# Generics and Interfaces concepts

  Hello, I am learning how to apply generics and when to use it. I saw an example somewhere showing how to use constraints in generics, where you can specity a Type which implements an interface, something like this: class MyClass<T> where T : IMyInterface { //here come all sorts of toying with T } Now to my question: what is the advantage of using generics here Why can't I simply refer to the interface After all I am limiting T to be an IMyInterface implementation.

• Visual Studio Express Editions Continuing despite exceptions

  I have designed a class that throws an exception in cases when it gets wrong input. How can I continue program execution normally even after it throws an exception For instance, if in the constructor I throw an ArgumentException, I want to continue processing the rest of the input. Right now, I have code that looks like this (to create a new instance of the class): RandomString randomString=null; try { randomString = new RandomString( comboBoxCharsToUse.Text, ",", "\\/:* \"<>|"); } catch (ArgumentException exc) { Globals.ShowError(exc.Message); } Globals.ShowError (randomString.All()); If an ArgumentExcep ...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
