• Visual Studio 2008 (Pre-release) Possible to remote an Expression tree into Yukon?

  So this crazy idea came to me over lunch. Yukon hosts the CLR.  It can also host a web service.  Provided that the CLR hosted has access to all the stock .NET framework, I wonder how worthwhile it would be to: 1. Create an expression tree at the client side. 2. Transmit the tree to a service on Yukon. 3. Have Yukon execute the tree in the context of the database (security being managed, of course). 4. Transmit the results back to the client. This would be an interesting way to solve the problem of SQL not supporting many of the things we should like, and no simple means to create ad hoc CLR procedures.  It's generally a bonus ...Show All

• Visual C# How to find registered event handlers?

  Hi, I'm trying to determine if an object has any event handlers registered on it. The reason I need this, is to not let an object to register one single event twice. this .menu.BeforePopup += new CancelEventHandler(menu_BeforePopup); // OK this .menu.BeforePopup += new CancelEventHandler(menu_BeforePopup); // Don't let it happen twice   Any help would be great You can only do that from within the class that provides the event, not from the outside. You have to write explicit event add and remove accessor methods where you can do any additional checks you want. Something like private CancelEventHandler _before ...Show All

• .NET Development Is Microsoft serious about serialization?

  I've been working through a serialization model have been stumbling over many semingly simple serialization problems that lead me to believe that Microsoft is not serious about serialization. There does not appear to be a unified model or methodology to the serialization within .Net. For example, the latest problem I hit is that the System.Windows.Forms.Padding structure is not serializable. Why is it that Microsoft did not tag this seemingly simple structure with the Serializable attribute Is there some criteria Microsoft uses to decide what is serializable and what is not Another example is the inconsistency of the formatters. They are s ...Show All

• .NET Development Changing Primary Key Columns in a hierarchical dataset

  Hi, I have one set of tables in my SQL db that I need to allow the user to change the Primary Key on (it's a Clerk ID for what it's worth). I've got the set of related tables up in a hierachical dataset, and the change to the primary key in the parent is being properly cascaded to the child tables (in the DataSet). I'm updating the db via a sproc using the original key values in my Where clause. My problem is, the Update to my parent table is cascading the Primary Key change to the child tables in the database . By the time my code calls .Update on the child table(s), the Original primary key record no longer exists (it's alread ...Show All
