Im using VBStudio 2010 Pro and I am writing to the registry the Font and Background colors so that my form load will apply the chosen colors. Can't get it to work for me though.
Am setting like this:
ColorDialog.ShowDialog()
My.Computer.Registry.SetValue("HKEY_CURRENT_USERBMSUFontColor", "FontColor",

I was curious why this bit of code won�t detect that the ARGB value is Blue:
[Code]...
When I run the code it says that the color isn�t Blue.
I need to create hex color to visualize wit it a number on google earth. Moreover I would like to create a small image file that depicts the color used in google earth. so I convert hex color from ARGB to brush color This is my

I'd like to know how to convert argb to rgb
View 12 RepliesI have a hexadecimal value contained in a string in the format like #FF00 for red, #0FF0 for green and #00FF for blue. I remove the hash sign so it's just the hexadecimal number but after that, I'm stuck? I know there's a convert.tostring or something but I'm not sure how to use it when converting from hex to decimal.[code]How do you do the reverse of this? From Hexadecimal to Decimal so I can create the argb value of my brush colour. If there is an easier way, please say but, as far as I am aware, Visual Basic.net 2010 doesn't let you define a colour using #0FF0.

View 7 RepliesQ1. is there a way to set an argb value to a Control?
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.AllowTransparency = True
Me.BackColor = Color.FromArgb(155, 255, 0, 0)
End Sub
i get error when setting BackColor "control does not support tarnsparent background colors"
Q2. is there any difference between this 2:
argb(255,0,0,127) "opacity is 1, blue is half" and
argb(127,0,0,255) "opacity is half, blue is max"
Q3. what if there are rounding off errors in the conversion to/from argb/rgb say argb(200,0,0,150) when converted to 255 opacity i get (255,0,0,117.5585938~)can i say that argb(255,0,0,118) is exactly equal to argb(200,0,0,150) or is argb(255,0,0,117) exactly equal to argb(200,0,0,150), or is there no way to exactly convert argb(200,0,0,150) to a value with alpha at 255?
Q4. is it true that there is absolutely no relation between argb and rgb, because the actual rgb value of an argb depends on the color of the element behind it?
i use this code to insert argb value from picturebox to listview

I'm looking to get the label to show the ARGB value of the backcolor on my current form using vb 2010.
View 2 RepliesWhy is it that in parts of the .Net architecture that ARGB colours are expected be as type Integer when ARGB is outside the range of Integer? (ARGB requires 32 bits of precission, but Int has 31 bits of precission).Now of course I could just do a conversion, but what freaking conversion to use??? (I'm not affluent with all the VB global methods and the sort)
I've tried things like:
Code:
Dim value As Integer = &H80000014
Dim uvalue As UInteger = CType(value, value)
''overflow others include Convert.ToUInt32 -> value was either to large or to small and a few others all offering up nonsense about overflows, when all I freakin' want is a colour that Microsoft's own engineers have done stupid things like expect Integer values in places where UInteger should be, or vice versa. How about some consistency...
Code:
Dim value As UInteger = &H80000014 ''<- not represntable as a Uinteger???
Dim uvalue As UInteger = 2147483668 ''<- same value in decimal, same exact value! and it works this says it's not representable as a UInteger?

I want the background of my form to be the same color as the window frame color that the user selects, even if that changes. I selected System->WindowFrame as my background color, but it always remains a dark grey, regardless of what I have my window color set to. How else would I achieve what I want? I assumed I was doing it the correct way. Do I actually need code that gets the system window color and then apply it?
View 4 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.

View 6 RepliesI know that with some of the programs I use, when you click on an item to change it's color, the color dialog will actually show the current color and it's rgb value.
I'd like to do that in my application but can't find the answer on how you do it.
To change the backcolor on a textbox, the user double clicks the box and it shows the color dialog.
I think I have all the properties set right -- fully open to show custom colors etc.
BUT, it doesn't show the current color.
They all have 0 0 0 rgb.
I would like to use a full range of possibilities for a color, such as 255,255,255 instead of predefined colors, like red. How can I do this in code. Me.backcolor=?
