• Visual Studio Team System [URGENT HELP NEEDED!] Unit Tests fail because of connection string problem

  Hi all, I am part of a six member group which is developing a hospital information system in the .NET platform using ASP.NET 2.0 and VSTS.

• .NET Development Best Practice: Activity status

  I'm back again! For me this is a bit hard to grasp/tackle. My application has a UI and several other classes. I know that no class should interact with the other if its not needed, which is fine. I know about these things. If I have a class doing some work (not the UI), I want to be able to notify the UI of the status/activity that is going on in this work. Is it correct for me to say that I should create events which would be raised from this class, so that the UI will catch it and display the status to the user Obviously this "work" class knows nothing about the UI class, nor does it need to. All it needs to do is its work and then display the status of what its doing, wherever this status is displayed is none ...Show All

• Software Development for Windows Vista It works.. there was great rejoicing

  Hello Everyone, I've created my own custom PropertyBindDialog because the one that Microsoft provides is pretty deficient. Unfortunately my own custom PropertyBindDialog will not be used after I call Activity.SetBinding - after I do this for a given property my own custom PropertyBindDialog is ignored and the Microsoft BindDialog is used. Here's some of my source code... The problem occurs when I call SetBinding on the property Test. After I call SetBinding, my PropertyBindDialog is no longer used when I want to edit the Test property - the Microsoft BindDialog is used and my custom PropertyBindDialog is ignored. Anyone out there have any ideas namespace MyActivityLibrary { public partial class MySpe ...Show All

• SQL Server Query optimisor out of stack space

  Hi, I have recently upgraded to SQL Server 2005 (SP1) Developer Edition from SQL Server 2000 (SP4). Since doing so, i have been unable to delete any records from a specific table. I have found this is due to having approximately 340 foreign key constraints referencing the UserID column of the table. This functionality worked in SQL Server 2000. Do Microsoft plan to release any fixes for this issue Kind Regards, Martyn... Wow, 340 FKs ! I don't think there is going to be a fix for this. The cost for maintaining this constraint is quite large. You should consider simplifying the schema. http://msdn2.microsoft.com/en-us/library/aa337357.aspx ...Show All
