Convert Hex To ARGB

Nov 29, 2010

I 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.

Set An Argb Value To A Control?

Dec 14, 2009

Q1. 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?

VB, Integer, Uinteger, And ARGB Colour Values?

Jul 21, 2010

Why 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?

Convert - Bytes[i / 2] = Convert.ToByte(hex.Substring(i, 2), 16)

Feb 22, 2010

See where my vb.net equivalent of a working c# assignment statement is not working?

bytes(i / 2) = Convert.ToByte(hex.Substring(i, 1), 16)

Here's the c# followed by the vb.net function.

private byte[] StringToByteArray(String hex)
{
int NumberChars = hex.Length;
byte[] bytes = new byte[NumberChars / 2];

[CODE]...

And the vb.net that is throwing the error within the for loop

Private Function StringToByteArray(ByVal hex As String) As Byte()
Dim NumberChars As Int16 = CShort(hex.Length)

Convert A Hex To An Int?

Jan 8, 2010

How do I convert a hex to an int. I know:

Dim hex as String = "FFFF"
Dim int as Integer = Val("&h" & hex)

The problem is that it only returns a signed integer, so the example above gives -1 instead of 65535. Is there a way to make Val return a Long instead f.ex. , or an other way ?
