Editing Colours Automatically?
May 25, 2012
With my program I have made a settings form - changing the colour of other forms- and instead of writing the code for each individual form I was thinking if I can create an automatic system. The forms have different types of names & the items within have different names.In the setting form i have 3 color dialogs (one for background,Text colour -labels-, and a button color -forecolor-)
Code for Formsettings
Public Background As Color
Public TextForecolour As Color
Public buttontext As Color[code]......

Public Class Form1
Dim x As Integer, y As Integer
Dim img As Bitmap
Dim pixelColor As Color
Public Function getpixel(ByVal x As Integer, ByVal y As Integer) As Color End Function Private Sub find_img_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles find_img.Click
[Code]...
whenever i load the image, i have to load it a second time to get the colour, or if i load a new one, i get the colour from the previous image, any ideas as to why?

I have a text box where I write different frames from a serial port.
I'd like to write those frames in two different colours but I don't know how to do it.
If I change the option Textbox.Forecolor, it changes the colour of every single line, and that's not what I am trying...

I have a colour that is not predefined and I want to change the selectionbackcolor in a DGV. In the DGV it is defined as 255,255,192.
RoomNamesDGV.DefaultCellStyle.SelectionBackColor = " a colour "
How do I set the colour using 255,255,192.I need to do this as I have 2 DGV side by side and I want to show where the focus lies.

I am using Visual Basic.NET 2008. I was earlier a VB 6 developer. I found a (VB 6) code online which generates gradient colours on a form. It has a small sub (routine) which does the trick. If we pass red, green and blue values then form's backcolour changes and it appears like a gradient.Now that code is not working in VB.NET.i mean is there an easier way to generate gradient colours in VB.NET (2008)convert the code I have into .net specific so form's backcolour becomes gradient.I have attached a zip file which contains the code.

I've found out how to change colours for the text editor, etc, but is there any way to change the colours in the help? It'd be nice to be able to have [for example] white text on a black background. It'd be easier on the eyes for lengthy reading sessions.No crops were circled, or animals mutilated in the making of this sig.

I'm a beginner to VB2010. If I draw a red line on a BLANK form, obviously its red. But if I draw a second red line, which crosses the first, is there a way of controlling the colour at the crossover position, for example returning it to the original colour of the form?

I've got a picturebox where someone can draw what they like on it and I have added a colordialog so the person can change the colour of the pen.[code]The trouble is, when I change the colour, the stuff ive already drawn on the picturebox changes colour too but I want it so that it only changes the colour of the pen and not what has already been drawn

I'm trying to make it so my textbox is colour-coordinated automatically. By this, I mean that if a line begins with a certain bit of text (for example, a line starting with <text>) then it will make the whole line red.I realise that this may not be possible with a standard textbox, so I don't mind any suggestions that need an RTF item.

Can I create a Pen dashpattern that consists of alternating colours rather than a solid colour followed by a space? For example:
LinePen.DashPattern = New Single() {6, 4}
creates a pattern with a dash of 6 pixels followed by a space of 4 pixels. Rather than a space, I would like a different solid colour. That way I could create a rectangular cursor with something like a black/white alternating pattern, which would be clearly visible on top of any picture.

I have an application that dynamically draws a chart onto a winform.Both the chart background and the individual chart bars are drawn using a VisualStyleRenderer object: For Each rect As Rectangle In barRectangles
Dim renderer As New VisualStyleRenderer (VisualStyleElement.StartPanel.UserPane.Normal)
renderer.DrawBackground(e.Graphics, rect)
next
this draws a nicely rendered rectangle with full XP visual styles, my question is: how do I change the colours used to draw the shape?

I've got a bar chart on my form which when I click a button, it populates with some data showing the clients net position, which is their assets vs their liabilities. This is shown on a year-by-year basis, so the graph will go up or down accordingly. If the graph goes into negative, or is negative at any stage, I would like it to turn red, and leave the positive values green. I have no idea how to do this, or even where to start looking into the properties. I'm still new to using the charts. How can I make the x-axis labels in increments of 5 from 0, instead of increments of 5 from -1?

I have an VB.net application in which I have imported the MSchart control 6.0. It draws all the bars in the same colour. I want to have each bar in different colour. I want bars of the same series to be so. There is only one series of data.

the new program I'am developing will enable the user to customise form and text colour.hese settings are to be applied to all forms used throughout the System.The method breakdown is as follows:1. User selects colour of form and text through hovering over a rectangle object of relevant colour.2. That information is stored to a text file.3. As the system is accessed again at log on, the settings are applied to all forms.

If you are working on a project that requires non-standard colours for text, it is possible to choose your colour by specifying the RGB components in the boxes on the colorpicker or by moving the mouse around until the desired colour is obtained. This can be put into one of the custom colour boxes and used until the program is shut down. Is it possible to save that colour to the custom colour box so that the next time the project is run, the chosen non-standard colour re-appears in the custom colour box?

This will sound an unusual question but I'm looking to find a way to reduce the number of colours of an image in a PictureBox from 1,000's to 15 and then apply a custom palette of 15 colours using a closest fit algorithm...
My graphics are never larger that 64x64 pixels generally, so the processing power / overhead needed to perform this operation is relatively small!
The inital algorithm I wrote is very slow and requires me to loop every pixel in the image and loop my palette doing a comparison to find a best fit colour.
Finding a decent method to do an initial colour reduction would be great!
I wondered if there were any inbuilt VB commands for PictureBox, etc that could be used to aid me in doing this...

I am using API calls to transform a Bitmap object. I have various physical transformations (rotation, flipping, scaling, displacement) as well as some colour adjustments (inversion, brightness and contrast)Everything works fine except for when I use the rotation or shear transformations in combination with the colour adjustment. In that case the colours revert to the original image.The interesting thing about this problem is that it seems to be dependent on the off-diagonal factors (eM12 and eM21 below) in the XForm matrix. For example, here is the rotation matrix:
Public Sub RotateClockwise(Radians As Single)
With XFormMatrix
.eM11 = Cos(Radians)[code]....
is there some way I can use both SetWorldTransform and SetColorAdjustment when using non-zero values for the off-diagonal factors in my XForm transformation?

I have a listview with a number of items with different color backrounds on each. But when i click on one of the items, the color of the item that the selection has just left turns to white, but it is recognised as being green/blue/whatever. If i open up another form on top of that one, and then close it, the colour comes back for the area that the form was covering.
I have a textbox that changes its backround color based on the color of the listview item currently selected, and that always shows the correct color.
I'v crawled the web and can only find one instance of it happening and that was a graphics accelerator problem, but i cant turn off my accelerator.

This is what I need to do:
Test 1: this test shows random colours in 8 boxes which appear in a circle shape. All boxes randomly change colour every .20 sec, and no two boxes display the same colour. At the same time a box in the centre changes colour to match one of the outside boxes. The participant must match in this box�s colour by clicking on the correct outside box colour. The score is then increased by 1 point for each correct answer. Each test lasts 1 min.
Test 2: the second test is the same as test 1 but instead of displaying a box filled with a colour in the centre, the word �green�, for example, appears in the green font colour. The word has �wide� letters so that there is plenty of colour showing. All other aspects are the same.
Test 3: the final tests uses random word colours but a different word. The candidate is required to match the Word and not the colour. Eg the word �GREEN� appears but the font colour is RED.The candidate must click on the colour GREEN to score a point.

I would like to create a little list in my Windows Form showing a list of custom colors with their 'friendly names'. Technically it can be anything (ListBox, ListView, Panel etc... whatever).
I simply want it to look something like this:
I would like to store data for this list in a simple TXT file in such form:
Quote:
Blue,Blue
Red,Red
#F6A118,My favourite color
#004080,Another color
And of course I would like each element on such list to be clickable, so if I'd click 'My favourite color' it should return the color's HEX value (#F6A118).
