Adjusting Brightness of a form

Question

Hi all,

I am developing a game where the form would dim periodically.

How do I achieve the dimming effect?

Please advise. All forums only talk about dimming the image (i.e. .bmp etc)

Thanks a lot!

Hi,

what do you mean with dimming the form? Dimming the BackColor? Dimming the BackColor of the Form and of all child-controls? Something else?

Basically it is a color-related task. You will have to get the luminance of the currrent color, reduce this luminance value and construct a new rgb-color from the hsl-values of the old color with the l (luminace) part replaced by the new value.

Or, if you use SystemColors, there are some "dark" and "darkdark" predifined Colors in the SystemColors class.

Hi,

Thanks for replying.

What I meant was dimming the the BackColor of the Form and of all child-controls (sorry if it was unclear!)

Is there anyway where I can do so in VB?
