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?

Is It More Efficient To Use UInteger Instead Of Integer

Nov 7, 2009

if there is no need for my variable to store negative values, is it more efficient to use UInteger instead of Integer? both are 4bytes and i've got a feeling unsigned works faster though i'm nt sure about it. note that the range of my variable is 0 to 2147483647, hence i could use a UInt32 or Int32 and both would give me the same result so i'm wondering about optimum performance.

Colour Picker Scanning - Log On Method - Users Selecting A Colour From A Paint Panel

Mar 15, 2012

To .NET after getting tired of using VB6 due to the lack of functionality. I'm trying to create a log on method for a system which will involve users selecting a colour from a paint panel and then placing/drawing the colour in 1 or more tiles of a grid, basically a 3x3 grid in which for example they selected the blue colour and drew in the top left tile and the bottom left tile. The logon is selecting the correct colour and placing the colour in the appropriate tile. What i want them to be able to do is place even a single pixel of colour so it has a high accuracy. So far i have a timer which loops from the width of the grid to the height of the grid.

Private Sub Timer1_Tick(sender As System.Object, e As System.EventArgs) Handles Timer1.Tick
Dim BMP As New Drawing.Bitmap(1, 1)
Dim GFX As System.Drawing.Graphics = System.Drawing.Graphics.FromImage(BMP)
GFX.CopyFromScreen(New Drawing.Point(MousePosition.X, MousePosition.Y), _

[CODE]...

To start with i have just hard coded the colour i want it to detect. At present it produces an error. Parameter must be positive and < Width the error is on System.Drawing.Point(i,j). If i place the mouse over the colour then run the program it will say it has been found, but otherwise it wont find the colour. I believe i am not updating the location of the pixel or something to that effect.

Replace All Pixels Of A Single Colour With A Different Colour?

Sep 16, 2009

I'd like to replace all the white pixels in a bitmap image with pixels of the colour "Color.FromKnownColor(KnownColor.MenuHighlight)". Is there some method in the Image, Bitmap or Graphics classes I can use, or will I simply have to inspect each pixel in the image with GetPixel, check whether it is a white pixel, and then set it with SetPixel?Here is the code I am using now:

Private Shared Sub highlight(ByVal b As Bitmap)

Declaring And Integer As Two Values

Jan 13, 2011

I'm working on a simple BlackJack (player vs dealer) system, that I plan on making gradually more advanced. However, while everything works brilliant, I'm yet to find a logical solution to declaring an Ace as both 1 and 11.So my question is, how do I pull this off. Below is the "New Game" logic (code) so it should give you an idea of what I'm working with (note how player scores are added together, I'm sure it's easy enough to understand...).I'd like lblPlayersum to still be a usable integer, though I'll rework everything if noone has a logical solution.Just quickly note that the "Cards" array is purely used to coordinate images."CardsVal" coordinates that values within the deck. Arrays 48, 49, 50 and 51 are the aces. (Currently defaulted to 11).[code]

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?
