 Using matrices to rotate a 3D world
This tutorial teaches you how to use matrices to create an efficient way to rotate and move a camera in a 3D world. Matrices are the most common way to work a 3D world in 3D graphics. The tutorial uses dots as items in the 3D world. The tutorial is visual basic orientated but the concepts apply to all languages
Matrices provide an alternate (better) way to rotate and move your 3D world. They are far more complicated than the last tutorial and use more difficult maths. You do not really need to completely grasp the maths to be able to use them but it is useful to have a basic understanding.

| Hiding and Displaying the Mouse Cursor in Visual Basic
This quick tutorial shows you how to hide and show the mouse cursor in Visual Basic.
Hiding and Displaying the Mouse Cursor in Visual Basic
Pesky, isn't it? I hate that little cursor sometimes, and now I'm armed and ready to kill it. The scourge of mice everywhere, the bane of the arrow, it's the ShowCursor function!
Private Declare Function ShowCursor Lib "user32" (ByVal bShow As Long) As Long
This tutorial is not for the faint of heart, or the verbose... this promises to be quite short. There are only two things you need to know about this API call, how to hide the cursor, and how to show the cursor. Notice I said "hide" not destroy. The ability to click is still there, even though we remove the cursor, there is simply no longer a graphical representation.
To remove the cursor, pass 0 (that's a zero not the letter 'o') as the bShow argument. To replace the cursor, pass 1 as the bShow argument, that's it! Here's an example in case you're a slow learner :)

| Card Deck and Shuffle
How to create a virtual card deck and shuffle it.
While I was creating my black jack game I wanted to make the user
feel like they were using an actual deck of cards. To make this
illusion even more accurate I decided that I would have the computer
keep track of which cards had been used and after all cards had been
used I wanted the deck to be shuffled. Therefore I had to figure out a easy
way to shuffle the deck. That is how I came up with the following method:
First I made an image control array called imgCards that went from
1 to 52. In this array I filled slot (1) with the ace of clubs, slot (2) with
the two of clubs, and so on I continued this process until I had all 52 cards
put into their corresponding slots. This would make the array look like this:

| Dynamic Usage of Event Handlers in VB.NET
In VB.NET we can receive and handle events in 2 ways. The first one is using WithEvents and Handles keywords, and the second way is to use the AddHandler method and dynamically add event handlers through our code and with RemoveHandler dynamically remove them.
Dynamic Usage of Event Handlers in VB.NET
by: Thomas Kaloyani
With Events and Handles clause requires form us to declare the object variable and the event handler as we write our code, so linkage is created upon compilation. On the other hand, with AddHandler and RemoveHandler, linkage is created and removed at runtime, which is more flexible.
Let's assume that we want to load several MDI child forms, allowing each of them to be loaded only once, and of course to know when one of the child forms is closed. Since we have several forms to load we would like to use the AddHandler and RemoveHandler keywords so we can be flexible and write the minimal code we can.
