Essentially I am searching an array for colors. If there is no input, on button click you get an error. If the color does not exist you get an error. If it exists then it tells you. The latter two events are not happening.

I'm not sure whether this post should be in the System.Drawing topic, but here goes... I need to create an array of colors to be applied into a Dundas Chart. The chart code is not the issue, but I can't seem to create an array of colours. Here's what I need to be able to do.

I am trying to create an array of colors. approach 2 doesn't work and I do not know why
Code:
'approach 1: works
Dim list As Color() = New Color() {Color.FromArgb(255, 0, 0), Color.FromArgb(0, 255, 0), Color.FromArgb(0, 0, 255)}
Code:
'approach 2: fails.. why?
Dim list() As Color = New Color() {Color.FromArgb(255, 0, 0), Color.FromArgb(0, 255, 0), Color.FromArgb(0, 0, 255)}
If instead I wish to create an array of strings, both approach works, that's weird.

View 5 RepliesI have a array of pixels. And I would like to Quantize them.
For Example
FF00FF,00FFFF stuff like that, but most are custom colors and are not a standard 256 color palette. So I need code to convert a color to a 256 color. I dont have any idea on how to do this, but thats why I came here. I do not want to use System.Graphics.Image.Palette or anything like that as this project uses arrays for images. I would like to if at all possible be able to convert a R, G, B color to 8bit, 16bit, 256bit and possibly use the HSL or NeuQuant method or something close to that, or maybe even some other methods of doing it. I do need to be able to do this for a single pixel, but I will also need a method for a array of them.
I've got an array containing lots of "Color" and I want to change the order of this colors (random) but with a password: so another user can get the "original" (and correct) sequence of the array only with the right password. How can I do this in Visual Basic .NET or C# ? Do have I to use a particular encryption engine?

View 4 RepliesI'm creating a little program to help my students to understand colour-mixing in Hex for their Web Design course. What I've got so far, is as follows: The user is presented with 3 sliders (one each for R, G and B) and a button. The 3 sliders each go from 0 to 15 - and when the user hits the "Show me!" button, Select Case jobbies translate the 0 to 15 values as seen here:

this is what i need to do: In the right-hand label, invert the colors of the image. Hint: the inverting white should give black and inverting black should give white. Inverting red (255,0,0) gives cyan (0,255,255). visual basic express 2008 this is what i have, what do i need to make changes to in order to accomplish this?

I am working on a program to generate 50 circles starting with the smallest in the center of the form. The circles do not over lap and the appear to grow outward. Each circle has to be a random color. I have the code that generates what I need but all the circles are the same color. I was thinking about either using an array to hold each circle and color as to not assign the same color to all of them but not sure about putting a graphic in an array. I also think maybe a nested loop of some sort but was unable to figure one out.
Private Sub mainForm_click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Click
Dim penColor As New Pen(Color.FromArgb(Rnd() * 255, Rnd() * 255, Rnd() * 255, Rnd() * 255), 2)

This works to do what I need to get done, I just need each circle to have a random color as it is drawn.
