Declaring And Integer As Two Values
Jan 13, 2011I'm working on a simple BlackJack (player vs dealer) system, that I plan on making gradually more advanced. However, while everything works brilliant, I'm yet to find a logical solution to declaring an Ace as both 1 and 11.So my question is, how do I pull this off. Below is the "New Game" logic (code) so it should give you an idea of what I'm working with (note how player scores are added together, I'm sure it's easy enough to understand...).I'd like lblPlayersum to still be a usable integer, though I'll rework everything if noone has a logical solution.Just quickly note that the "Cards" array is purely used to coordinate images."CardsVal" coordinates that values within the deck. Arrays 48, 49, 50 and 51 are the aces. (Currently defaulted to 11).[code]

Error After Implicit Conversion Of 1 Dimensional Array Of Integer To IEnumerable Of Integer() ) ?
Apr 25, 2011I'm trying to create a linked list of an array of integers. Why is the following implicit conversion required?
When I run the code that contains that conversion, I get the following error.
As a real-time data acquisition user control data (a packet of an array of bytes) arrives every second, is converted into an integer array and inserted into a linked list.
The most recently arrived data is painted as coordinates on a grid at the right of a PictureBox using Graphics.DrawLine (pen,X1,Y1,X2,Y2).
The oldest data (arriving 120 seconds ago) will be drawn at the leftmost portion of the Picturebox.
Why a linked list rather than a list? To display 120 views of time sequence data, the draw routine the most recently inserted node to a node that points to Nothing. How do I limit the length of the linked list to 120 nodes and always ensure that the last node points to Nothing?
Do While Not item Is Nothing
item = item.NextItem

Is LinkedList Implementation Of .Net Threadsafe
Apr 26, 2011I am working on an application which uses multiple threads to work on number of tasks and the parent application receives the output of the task,later to be written to files, currently I am using arraylist to append output to, but that happens to be slow when removing items from queue.I was thinking to convert arraylist part to linkedlist for optimized reads and clears,if linkedList Implementation of .Net is threadsafe or even using arraylist was threadsafe?

VS 2008 : Error: ConvertToMonth Is Not A Member Of Integer
May 20, 2009I ran into a strange issue over the weekend while I was working on an asp.net mvc project in vb.net.

In my asp.net mvc project I have a view and want to call the extension method but I get an error that the extension method is not recognized. I imported the namespace it was contained in and still couldn't shake the error. Any idea what's going on? The code is below.

The math isn't hard to do, it's just that much of it is trial and error, and redoing all the arithmetic over and over again until the aircraft's C/B is in acceptable limits can eat some time up. So, since i'm trying to learn programming I thought this might be a good way to use it for a real-world scenario.
