Keydown problem - Help!!

I have beenn pulling my hair out all night about this. Ok. I'm making a PacMan game using BitBlt. Here's my code for the form thats the problem:

Code:

---

Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)
Select Case KeyCode
Case vbKeyLeft
MLeft
Case vbKeyRight
MRight
Case vbKeyUp
MUp
Case vbKeyDown
MDown
End Select
End Sub

Sub Render()
'blit it on the buffer, mask first
BitBlt BackBuffer.hDC, PacMan2.x, PacMan2.y, 56, 58, SpriteMask.hDC, 0, 0, vbMergePaint
BitBlt BackBuffer.hDC, PacMan2.x, PacMan2.y, 56, 58, Sprite.hDC, 0, 0, vbSrcAnd
End Sub

Private Sub Form_Load()
'Show the form
Show

Draw
MainLoop
End Sub

Sub Draw()
'Set where the pacman starts
PacMan2.x = 40
PacMan2.y = 40
End Sub

Sub MainLoop()
Do
DoEvents
BackBuffer.Cls

Render
Loop
End Sub

Sub MDown()
PacMan2.y = PacMan2.y + 15
End Sub

Sub MUp()
PacMan2.y = PacMan2.y - 15
End Sub

Sub MLeft()
PacMan2.x = PacMan2.x + 15
End Sub

Sub MRight()
PacMan2.x = PacMan2.x - 15
End Sub

As you can see, when you press up, the sprite moves up, etc.

HOWEVER, nothing happens when I do. Even if I type the wrong thing, for example: MUp22 (which is not a Sub or anything), I dont get an error message, meaning that the program isnt responding to the key at all, none of them actually.

What am i doing wrong? thanks in advance.

Is the KeyPreview property of the Form set to True?

Also, I don't see you refreshing the form either

Well the code he posted is not using any continious loop or anything so the Form will refresh itself since most of the time none of the code will run at all.
