Listview, HideSelection And Row Colour?
Oct 9, 2010
I currently have a listview on a forum. The user will select an item and press a button, presenting a second form with data based on their selection. In the event that the user wishes to return from the second form back to the first, the selected item in the list view should still be selected.
I have set the hideselection property to false, but have found that the selected item will be a light gray as opposed to the normal blue. Can anyone please tell me how to change the colour so it will always be blue?

Is there any way to change the default colour to the highlight when a listview row is selected? Apparently the default blue colour causes some problems for some users who have some visual eyesight problems. They didn't tell me what colour they wanted but they did indicated the blue is annoying.

I am making a diary Form in VB.NET to do this I am using a listview with two columns.
Column 1 consists of a list of time and column 2 is the description
Can I change the colour of certain cells in column 2 only. So when I read in the data from the database it reads in the description and then puts the data in the relevant time slot but I want the recent cells of the description column to be a different colour.

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.

It always defaults to the first item in the colour list I've tried

[code]...
It displays the color of the pixel at the coordinate typed into the text boxes.I have a video of a tennis ball which is bouncing on the spot, and the background in brown, so when the tennis ball comes into view there is a significant color change and i want it to start and stop a timer each time the colour changes significantly.So my question is, how do i get it to check whether the colour chas changed significantly?

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)
Dim highlightColour As Color = Color.FromKnownColor(KnownColor.MenuHighlight)
Dim whiteARGB As Long = Color.White.ToArgb

I have created a program that Draw a circle and then you can move it around a picturebox. I have made code so that it changes colour but instead of changing the colour of the circle already been drawn it creates a new circle which when you overlap the original circle with the new circle it cuts part of it.So what I wanted it to do when I change the colour of the circle it changes the colour of the circle already been drawn instead of creating a new circle.
[Code]...
Also I can't use the X and Y coordinate input to move the circle to the entered coordinates.

I am making a html editor in visual basic 2010 for Uni and i am coming across some problems.
I'm using the richTextBox because it is more editable for what i am doing. The first of my questions is: How can I change the colour of text.
What I have done so far is add a timer that will constantly check to see if the user has entered... lets say "<div>" then i want that text to change to a different colour... say red.
My second question is: Obviously in web dev when you write the <div> tag you have other content inside it like: <div id=""/> so how can i make the entire string between the < and the > or the <div> </div> become the same colour.

I need to convert a VB.NET colour to a hex code.Here is my code thus far:
TextBox1.Text = ColorTranslator.ToHtml(Button1.BackColor)
The back color of button 1 is red. However when I use this code the textbox types "red" instead of "#ff0000". Is this because when typing HTML, most normal people would type:
<font color="red">
<!--- Instead of typing --->
<font color="#ff0000">

I have written a program to return the colour of a pixel from an image. The problem I have is I need to return the colour name. Of course not all colours returned will be one of the pre-defined colours (knowncolours), so my question is, is there a way to find the nearest knowncolour which matches the colour of the pixel?
I have looked at GetNearestColour but am confused by its function. It just seems to return the same colour as the parameter passed into it.

I'm trying to make a text editor, and I want to make it highlight different syntax in different colours.
E.g. when the user types in <html> I want that to appear in red.
How exactly would you go around doing this?
For a better visualisation, this is what I have so far:
From the properties pane of VB.net, I can only change the whole TextBox's font colour.
