• Visual Basic Updating Multiple Related Tables in a Database

  Hello. I am new to the VB 2005 arena, and apologise if I am asking a stupid question. But I am really stuck on one thing. I have many tables in my database all of which are related to each other in one way or the other. All the relationships are one-to-many. I am using MS Access 2003 and the database format is Access 2000. The problem is that whenever I try to update a parent table it says that a child table contains related records so I cannot change or delete any records. And I am not able to update any tables.

• Visual Studio 2008 (Pre-release) Sum in Query Expression

  Is it possible to do the following using query expression syntax: decimal total = customers     .SelectMany(c => c.Orders)     .Sum(o => o.Total); Or can this only be done presently with the extension methods Not every Standard Query Operator is currently represented by a Query Expression analog.  But since Query Expressions all return IEnumerable<T>, and since Standard Query Operators are extension methods that operate on IEnumerable<T>, .Sum() can be invoked on the result of a Query Expression: (some_query_expression).Sum() -Scott ...Show All

• Visual Studio Express Editions Tab Control _click Doesn't

  Ok I give... The tabcontrol_click event. As I read the 'help' file If there is at least one TabPage in the collection, and the user interacts with the tab control's header (where the TabPage names appear), the TabControl raises the appropriate event.
