View 2 RepliesI've been trying to create a random brush color generator, Something like this code (it creates random colors...)
vb.net
Dim rnd As New RandomDim newColor As New ColornewColor = Color.FromArgb(rnd.Next(0, 255), rnd.Next(0, 255), rnd.Next(0, 255), rnd.Next(0, 255))
So, reading around varous places, (MSDN, these forums, CodeProject etc.) it's clear that you should dispose of any Pen's, Brushes etc. that you create and that perhaps the best way is via aUsing block. But some behaviour has confused me and I think it might be related to the color I use when I create the Pen / Brush (read this in a post in the C# forums).It now works since I've used a Using block to replace the Dim....Dispose() shown below. But I don't understand why because all the Using block does is ensure that the used object is disposed of. It's just short-hand for Dim....Dispose() - at least that's what I understand

Dim _Brush_Disabled As New SolidBrush(Color.FromKnownColor(KnownColor.GrayText))
Dim _Brush_Enabled As New SolidBrush(Color.FromKnownColor(KnownColor.WindowText))

Will _Brush_Disabled and _Brush_Enabled automatically change their colors if the Windows color scheme changes?If not, how can I make them 'track' Windows color scheme changes?

View 1 RepliesDoes anybody knows if it is possible to convert a numeric value into a System.Drawing.Color (or Pen) value? I need to implement the following code:MyBitmap.SetPixel(x,y,MyColor)
MYColor is a long integer and does not work because the above code needs a system color.
i need to do is how do i create a brush color in my.settings? because System.Drawing.Color is not for Brushes is it?

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 to get all of the Brushes, this is basically pseudocode which will explain what I'm trying to do:

Brushes is a type though so how would I be able to do that?

View 3 RepliesI would like to create a reflection of a text on an image. I have used so far this:
g.DrawString(TextBox3.Text, myFont, myBrush,and i have tried some methods but none seems to work.
for example a g. transform used with matrix could do that
If I could use the DrawRectangle method to cast an Inverse colored rectangle on a graphic, it would be easy, but seaching through all the brush/ image attribute/texturebrush members, I cannot find the "inverse" option.The direct manipulation of a bitmap using bitmap.setpixel(x,y,color(255 Not getRed,255 Not getGreen, 255 Not getBlue)) is probably what I will use if nobody can show me a more "SPECKY" way.[code]
