Gradient fill?

Does anyone know how to fill a form (or a picture box) with a gradient? Any help would be appreciated?

Thanks.

For "sided" gradient

for z = 0 to 255
me.Line (Y * 10, height)-(Width, Y * 10), RGB(0, Y, 0), BF
Y = Y + 1
next z



for horizontal
for z = 0 to 255
me.Line (Y * 20, Height)-(Width, 0), RGB(0, Y, 0), BF
Y = Y + 1
next z



for vertical
for z = 0 to 255
me.Line (0, Height)-(Width, Y * 15), RGB(0, Y, 0), BF
Y = Y + 1
next z



if you want to invert the colors then just use negative values and use scalewidth/scaleheight, you might also want to place a scalemode to pixel
to create really nice gradients, playy around with variables and you can make really nice effects...like light ray or tunnel, etc.

Good Luck

just another example:

Y2 = me.ScaleHeight
X2 = me.ScaleWidth
for z = 0 to 255
me.Line (0, me.ScaleHeight)-(Y2, Y2), RGB(0, y, 0), B
me.Line (me.ScaleWidth, Y2)-(Y2, 0), RGB(0, y, 0), B
y = y + 1
Y2 = Y2 - 1
next z
