How to Make Gradients

This code will draw a gradient on either a form or picturebox or possibly anything that has an hDC property.

Just call the DrawGradient Procedure and pass it these values:
lDestHDC - The hDC of the object you want to draw to
lDestWidth - The Width of the Gradient
lDestHeight - The Height of the Gradient
lStartColor - The color the gradient starts out with
lEndColor - The color the gradient ends up with
iStyle - 0 for left to right gradient or 1 for top to bottom gradient.

Create a new module and insert this code
