[For Visual Basic .NET]

This is my first tutorial so bare with me. I noticed how dead the Visual Basic Section is. I think we just need more content. So anyway, you may have noticed if you have worked with Visual Basic.NET for any amount of time. That keyboard input is not fun. It's because it only checks one key at a time. This really sucks if you want to make a game. So, Here is how you get around it.

First you need to put this after your Public Class.

code:
Private Declare Function GetAsyncKeyState Lib "user32.dll" (ByVal keyCode As Integer) As Short


This sets up input for the command 'GetAsyncKeyState()'.

That is pretty much all you need, that command checks the keys state when you want it to, rather than one at a time. So, if you want to check for the input you could try:

code:
If GetAsyncKeyState(83) Then
     ' Do your stuff here.
End If

83 being the S key.

The down side is you will need to use key codes. There is a list here.
I hope that was acceptable, enjoy!

How different is .NET from VB6?

I couldn't tell you. I just started learning Visual Basic .NET a week ago. Haven't gotten in to Visual Basic 6 yet.

Yeah, same... I really want to use VB.NET, but my teacher is against it for some reason or another. I so, I'll need to learn both. Neither look difficult. So it should be child's play. Razz

The only reason I use VB is because that's all they teach. If I were you I would stay clear of VB, and only use it for school purposes. There are better languages you can teach yourself Very Happy

Yeah, I want to find a good one to learn, but I can't make up my mind. I figured I stick somewhat to curriculum until i figure it out.
