Black And Blue (color Testing)
Aug 4, 2010
Provided the following
vb.net Private Function isBlue(ByVal aRGB As Color) As Integer
If aRGB.R < 30 And aRGB.G < 30 And aRGB.B > 170 Then
[CODE]....
I use it with the following:
vb.net Dim count As Integer = 0
Dim img3 As New Bitmap(DirectCast(CameraTable.Controls("camera" & z.ToString), PictureBox).Image)
For x As Integer = 10 To 16
Works great. Takes a small square and tests for the blue color indicated by the aRGB value.
What I am trying to do now is test for all Black (as opposed to blue). I want to copy that isBlue Sub to a "isBlack" Sub and perform a like test, but I do not know what to use for this part:
If aRGB.R < 30 And aRGB.G < 30 And aRGB.B > 170 Then explain those values and what changes to each one does?
I've edited the code some:
vb.net Dim bluepixels As Integer = 0
Dim blackpixels As Integer = 0
Dim img3 As New Bitmap(DirectCast(CameraTable.Controls("camera" & z.ToString), PictureBox).Image)
[CODE]...
And in the sub I am testing for an R, G, and B value less than 3 (black should be all 0's) I'm still interested in how to manipulate those RGB values to test for other colors, or very specific hex colors.

I have a form with a lot of LineShapes on it, and basically what I'm trying to do is make certain lines a blue colour and others a black colour, depending what it's in an array of integers. Each line is called line1, line2 etc. So if one of the values in the array is 3, then line3 would be coloured blue.
I have the following code to handle all the lines more easier:
MeterArray = New PowerPacks.LineShape() {line1, line2, line3, line4, line5}
However, since I'm going to have about 50 seperate lines, this is going to look quite messy when I reach line50. So my question is, is there a tidyier way of handling these lineshapes.

He wanted to know how they can do to convert a portion of the form that you see only blue or black and white. I mean, the user presses a button and all that is in the form sees only blue or black and white only.

[URL] That way if the string that is not recognised that is passed to Color.FromName it returns a SolidColor of
Color.Black = Color.FromARGB(255,0,0,0)
That way, Forms and controls that only support SolidColors are supported.Installing VB6 on Windows 7?

Even with <label>.forecolor = Color.Black. I find that my labels' borders are not {255,0,0,0} but rather {255,100,100,100), a middlish gray, Is there some system setting (e.g., themes, Silverlight) from which the standard label draws its color?( I am familiar with the sub-classing work-around, but have hundereds of instances that would have to be changed.)

So I have a Vertical Scroll which enables you to change the Foreground color of the highlighted text inside the Rich TextBox. Here is the code of the Vertical scroll named Vscrollbar1:
RichTextBox1.SelectionColor = Color.FromArgb(VScrollBar1.Value)
It does indeed work. Then I have a button that makes the Rich Textbox not Visible. Using Richtextbox1.visible=False Then I have an open button, which makes it Visible again. But what I wanted is that the text inside the Rich Textbox to be color Black; but the color of the from the scroll keeps appearing. Here is my code for the Close Button:
Richtextbox1.SelectionColor=Color.Black
I even changed it to this:
Vscrollbar1.Value=0
But still no difference.

I am using the cursor converter to set both
dim cCon as cursorconverter = new cursorconverter
me.cursor = cursorconverter.ConvertFrom(myCursor.cur)
and
windows.forms.cursor.current = cursorconverter.ConvertFrom(myCursor.cur)
the reason for setting both is that otherwise the cursor will not always have the desired appearance. I know that cursors can be rendered in color, like 3D-Bronze, windows animated, hands and variations.

I would like to load a GIF file, and start with the first pixel and check to see if that pixel color is closer to Black, Red, Green or Yellow, then take what ever color it closest matched to and output that color as a number, 0, 1, 2 or 3. So just for a small example a 5x4 GIF would be converted to something like this: 0112223322220111332?

I'm looking into adding some unit tests for some classes in my data access layer and I'm looking at an update routine that has no return value.It simply updates a row based on the id you provide at whichever column name you provide.Inside of this method, we collect the parameters and pass them to a helper routine which calls the stored procedure to update the table.Is there a recommended approach for how to do unit testing in such a scenario?

I'm building an Active Directory wrapper in VBNET 2.0 (can't use later .NET) in which I have the following:
IUtilisateur
IGroupe
IUniteOrganisation
These interfaces are implemented in internal classes (Friend in VBNET), so that I want to implement a façade in order to instiate each of the interfaces with their internal classes. This will allow the architecture a better flexibility, etc.Now, I want to test these classes (Utilisateur, Groupe, UniteOrganisation) in a different project within the same solution. However, these classes are internal. I would like to be able to instantiate them without going through my façade, but only for these tests, nothing more.

I use VB2010 Express on a Win7(x64) desktop. I use the following code to select items from data listed in a ListView and then save the selections to a database when I have finished choosing. I use the following code
[code language="VB.NET"] Private Sub ListView1_Click(ByVal
sender As Object, ByVal e As System.EventArgs) Handles ListView1.Click
Dim z As Byte = ListView1.SelectedItems.Item(0).Index
Dim n As Byte = 0
[Code] ......
Each time I click on an item in the list, that item is highlighted in Blue. When I click on another, the highlighting transfers to the new item and the previously selected item is green. The HideSelection has no effect on the highlighting, nor does transferring the Focus to another control. How to get rid of the blue highlighting as the only way I have found is to click in the listview control below the data which is counter intuitive.

I have three HScrollBars(for the colors red, green, blue and maximum to 255), a picturebox(to see the output color) and a textbox which gives the color in HTML output. For example: 0xE60000FF >> This is a red color.I know I first should make a code and paste it here, but I really don't have any idea how.
