When editing a code module, any methods marked as Obsolete do not (by design) show up in the top-right hand declration drop-down. (I've rasied this as a problem on another thread since it's causing me and other colegues a head-ache. Can I propose a VS setting to include obsolte methods would be a simple and useful enhancment.)

View 6 RepliesI'm working on a Visual Basic application in Visual Studio 2010. The application was originally created in VB6, which had a dedicated menu button editor. Now I need to add new drop-down items to my button menus, but VS10 seems to have no facility for this. All attempts so far appear to lead me to tool strip support, which I do not want.

View 9 RepliesI've been creating short test apps repeatedly to try to understand some of the concepts in VB.NET.For the most part it has been illuminating.I read Bucky's .NET knowlegebase tutorial on passing objects as parameters to newly created forms. He shows how to create a new class that inherits from the base form class and define a New() method with parameters Extending the concept I thought about doing the same thing with a form that was created at design-time (In this case Form2).

Base class has one field to hold numeric balance value. With 2 methods that accept arguments for adding and subtracting the new input calculating new balance. Sub class has four fields dates, transaction, memo and amount.I have a deposit form, and withdraw form. Each time one transaction is entered it creates an object with sub class fields, then adds to the account collection. My problem is not understanding how to call the deposit/withdraw method and pass the current transaction amount back to the base class to alculate the new balance. Does anyone have any links to information/tutorials on how to perform something like this? As you can see with my code I have tried various different approaches without any success.

Obviously, I don't wish that the class Glider has the method "start_engines" neither the property "num_engines". Otherwise, other child classes may have. How can I supress these property and method in child class, not just ignoring (if I can)?

i know is there any simpler ways of coding to enable the user to drag and drop button and this button will toggle the background color when the condition is true.
