    Here's an example, getpixel is the same as point and setpixelv is the same as pset, except api's faster and you need to specify the dc
    Code:
    'In declarations
Declare Function SetPixelV Lib "gdi32" Alias "SetPixelV" (ByVal hdc As Long, ByVal x As Long, ByVal y As Long, ByVal crColor As Long) As Long
Declare Function GetPixel Lib "gdi32" Alias "GetPixel" (ByVal hdc As Long, ByVal x As Long, ByVal y As Long) As Long

'In code

Dim Color&
color = getpixel(picture1.hdc,10,10)
setpixelv picture2.hdc,15,5,vbred
    Use
    writing software in C++ is like driving rivets into steel beam with a toothpick.
    writing haskell makes your life easier:
    reverse (p (6*9)) where p x|x==0=""|True=chr (48+z): p y where (y,z)=divMod x 13
    To throw away OOP for low level languages is myopia, to keep OOP is hyperopia. To throw away OOP for a high level language is insight.

    Aslo, you should remember to set your Form's Autoredraw property to true and remember to refresh the Form after you have drawn on the DC.
