[2005] Convert Color Image to a Gray Shade Image

Hi all,

I'm creating a custom button control. I need to show a color image when the button control is enabled and a gray shade of the same image when the button control is disabled. How can i convert a color image to a gray image in VB 2005.

Thanks,

Here is how you do it in vb.

You can also use a third party program to make a copy of your image in grayscale and use it when button is disabled. I would go this way myself as it would be faster and your code would be smaller. Use IrfanView, get it here,
